Here is an entertaining and well researched video documentary from my friend John Coleman at KUSI-TV about the history of the Keeling Curve and its founder.
Watch:
From the YouTube description:
A great scientist named Roger Revelle had Al Gore in his class at Harvard and the Global Warming campaign was born. Revelle tried to calm things down years later, but Gore said Revelle was Senile and refused to debate. John Coleman documents the entire story and shows how our tax dollars are perpetuating the Global Warming alarmist campaign even though temperatures have not risen in years.

M Paul, actually Russian scientists were one of the first to have promoted a coming ice age, and Ukraine’s politicians voted to annex with Russia. Since when has Russia ever agreed with the west?
There is a good book ” Ice not Fire’ – Al that will kill us. Written years ago. Having studied archaeology and palaeoanthropology, the pattern of our global climate changes seem to indicate we are in for a cooling episode but it may not actually come to a full glacial period for a long time.
And it may not involve all the globe, the Northern Hemisphere will probably be most affected, but we are smart we should be able to do something about this before it becomes catastrophic.
Have you read Colleen McCullough’s ‘Creed of the Third Millennium’. Not one of my favorite books, but did she do a good job, describing what a Northern hemisphere ice age was like.? She had scientific advice on this one too. Worth a read.

To put that in context, in 1988 we had had what was at that time a record-warm year for global temperature but now it has been 18 years since we had a year that cold!
= = = = = = = = =
The constantly revised, adjusted, homogenized and pasteurized mathematical abstraction called “global average temperature” apparently has no relationship to what’s happening on the ground.
For example, your gurus from the Hadley Centre for Climate Prediction and Research told us, only 14 years ago, that “snowfalls are now just a thing of the past.” As you probably know, that is the most widely read and laughed at report on the Independent website to date! But it wasn’t just the predictions from Hadley:

(a lot of misinformation about Thorium)
Many years ago I was a qualified nuclear engineer, much technology has changed but not the basic physics (which was pretty much determined by 1947 along with the many proposed reactor basic designs)
You can NOT build a reactor out of thorium (just like natural uranium). You could have a mass of thorium the size of the Earth and it would not go critical (you would get a whale of a lot of heat from the alpha decay but fission would be an extremely low order probability)
What the idea behind a thorium “reactor” is that a normal reactor (fueled with U235 or Pu239) surrounded by a Thorium (naturally Th232) blanket would generate U233 via neutron capture. The U233 would then be the fuel in a reactor . Notice that there is very little difference between this blanket that generates U233 and a U238 blanket which transforms to Np239 decaying to Pu239.
If you let the U233 sit in the reactor it can fission (just like Pu239) or it can add a neutron to form U234 which like the counterpart Pu240 is basically nonfissionable. In fact with a little more neutron capture you can end up with evil plutonium , the bugaboo of all the antinukes.
So you have to have a uranium reactor to get thorium to form uranium to serve in your reactor.
Now as to the claims of no bomb making ability. Totally false. U233 makes a poor bomb, but as scientists and engineers demonstrated at Yucca Flats, with a bit of careful engineering you can get a nice big atomic bomb blast (which is the core of any hydrogen bomb). And since you would have a 99+% U233 available with only chemical separation instead of isotope separation you actually have a greater risk of diversion of nuclear fuel into weapons production. Never underestimate the creativity of engineers, especially those who have a CAUSE.
The radioactive daughter products of a U233 fission are pretty much identical with those of a U235 fission (a bell curve of just about every neutron proton combination with peaks around Strontium and Iodine plus various numbers of free neutrons and delayed neutrons). So the radiation effects and contamination problem would be the same (as they are with U235 and Pu239 systems). So the antinukes will get their lawyers up in arms and increase the cost of your power reactors far beyond simple engineering costs.
The 9 points you mention are totally false or irrelevant, any competent physics student should be able to point out the mistakes, so it is obvious that you are either spreading false information or do not know anything about nuclear engineering.
:
1. Safety – a completely no-explosion, no radioactive release system.
False, you can make a bomb using thorium just like you can a reactor – you just have to convert it to uranium.
2. Is 150 times as efficient for extracting energy from the fuel (99%+ vs 0.7%).
Only if you ignore the U238 which can be changed to Pu just like Th goes to U.
3. Known thorium reserves and in storage is sufficient for thousands of years
And Uranium reserves are larger.
4. Will be used to use up (as in clean up, forever) the already existing nuclear waste
So can any reactor if you add enough reactivity. (but that does not eliminate non fission fragment radioactives like Cobalt 60)
5. A ball of thorium the size of a racquetball contains all the energy for one person for their entire lifetime.
And a similar sized ball of Uranium has even more energy.
6. Reactors can be sized up or down – to small enough to power a small town or a medium-sized company.
Yep. and the only reactor to kill an American (SL1) was a “portable” Army reactor that suffered a control rod removal prompt criticality steam explosion that killed the 3 operators.
7. Reactor construction costs of about $600 million (at current efficiencies) vs $20-40 billion (depending on cost overruns) for light water reactors.
Until the lawyers get active.
8. Instant shut down – The pilot reactor was shut down on Fridays and turned back on on Monday mornings.
Almost all reactors have the instant shutdown – it is called the SCRAM switch. The problem is that the daughter fission fragments continue to produce about 7% power levels from delayed neutrons so you can not just walk away (unless you have zilch power history) And Thorium has the same daughter fission fragments as Uranium or Plutonium.
9. Non-proliferation, because of its own physics. The fuel cannot be stored in missiles for any length of time without irradiating and destroying the controls. The fuel also gives off so much radiation that it is impossible to hide the weapons. The military 50 years ago decided thorium was not usable for nukes.
Remember that U233 bomb at Yucca Flats. Sure you may have to have the control components separated to have safety and long life. But a similar safety problem existed on our Mk45 nuclear torpedoes. The way we armed them was to open a hatch, pull out a control block, turn it around, then reinsert it. You could just have the control block stored separately and take a couple extra seconds in the arming process. (and the military decision was not that U233 was not usable, it was that Pu239 was cheaper and U235 and Pu239 were better materials)
If you wanted a safe reactor system I would suggest a look at the molten salt SUB critical designs. The same high operating temperature to achieve high thermal efficiency, but designed to be sub critical always. It is forced to criticality by the addition of massive amounts of neutron provide by a set of high energy neutron generators. (powered by the reactor). These gigavolt neutron generators tip the condition into critical and allow powerup. They effectively act as additional control rods with the difference being that they must be operating to allow criticality rather than poisoning the reaction like inserted control rods). Safer since it is better since you WILL have shutdown without the extra neutrons compared to SHOULD have shutdown with control rod poisoning.
Even jet aircraft can get their energy from thorium. Not directly. They can use electrolysis to make hydrogen and switch over from jet fuel (kerosene) to hydrogen.
Ever look at the density of hydrogen? We can’t even efficiently use it for ground vehicles let alone mass sensitive things like planes. The problem is not H mass, it is the mass of a gas tank. And hydrogen likes to slip through cracks and weld joints, with liquid hydrogen being even more evil.
In addition to thorium, 4.7 billion a year could give us graphene that much sooner. And what does graphene do? Well, among MANY other uses, coating electrical terminals with them has been found to make recharging batteries more than ten times faster. It is also the strongest and hardest material by weight ever known. It is also the best non-friction surface treatment ever known – better than teflon.
I later worked as a high energy chemist. One of our products was Graphite Monofloride. (CFx ) A much cheaper and better lubricant than Teflon, and considering its structure, probably than grapheme. (and has been around for about 50 years). It was shown that a small amount added to a grease provided much better coefficients than the best high temperature molybdenum disulphide grease.
Industrial inertia overcomes better science just about any day!

I am curious –
I am trying to understand how this so off topic drivel wasn’t snipped by a moderator. Does it serve a purpose that I can’t fathom?
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Personally I think it is very topical. Think in a world view, and where the power shift is. Read “Confessions of an Economic Hit Man” then think about what is happening with the BRICS countries and what that alliance might mean down the road given they don’t really buy in to the AGW meme. That means they focus their resources elsewhere – on economics, health, pollution, energy, resource development AND even their versions philanthropy (with strings tied of course, but no different than the western powers for the last 100 years). The shell game and where is the pea requires distraction and AGW certainly provides a distraction – at least for me since I read this site regularly. But some people devote their lives to AGW and I often wonder what their motivation is. Even if it is benign, it gives other countries an opportunity so it is relevant if you look at the “big picture”. We have some governments telling us “Climate Change” is the number one concern while most of us are worrying about food on the table and a roof over our heads. Who has their eye on the ball – the IMF or the BRICS countries? I am not sure, but I do think about it. (Darn those John Grisham, John Le Carre, Frederick Forsyth, Chrichton, and a host of others. But so much fun 😉 )
Reblogged this on The GOLDEN RULE and commented:
Thanks to WUWT for posting this presentation.
There are a few minor imperfections but the overall information, science and conclusions are fully substantiated by the contents.
It is a telling point that the scientist who basically initiated the scare of CO2 being significant in affecting global temperature, later recanted and tried to redeem himself, only to be labelled as senile. Typical instance of the documented truth being swamped by rhetoric and blatant lies.
Then the issue of funding – CO2 influence and carbon trading skeptics are criticized as being funded by vested interests, yet the whole global warming scare empire was built up and is still sustained by mega financing from governments. Strange how, again, truth is squashed by untrue misinformation.
Anyone wishing to debate the validity of this presentation is invited to comment with sensible and logical questions or refutations.
Thanks for the effort, Mr Coleman.
@Albert Whiteman Smith –
Oh, Keerist, I’ve got to go through this point by point. . .
To say that a thorium reactor is not a thorium reactor is like saying that bread eaten is not fuel for the human body because it doesn’t enter the bloodstream as bread crumbs. Ignorant point. I did not think it necessary to spell out every step of the LFTR process. No, the throium is not the actual fuel in the core. But it is the material we take out of the ground and enter into the beginning of the process, to irradiate it so that in a month’s time it turns into U-233, which is the fuel actually driving the core. But because bread sits in the stomach for a good while does not make bread a non-fuel for the body. In the same sense liquid gasoline is not the fuel for cars. Only in the vaporized state does it become volatile. One does not pull up to a gas station and buy vaporized gasoline. Your point is pedantic.
Earl, just because you worked with light water reactors doesn’t mean that you know what is going on with LFTRs unless you’ve educated yourself about LFTRs – specifically.
Yes, the core has to deal with radiation and contamination. Duh.
1. No, the energy producing SYSTEM cannot be exploded. You are talking about something other than the reactor. You are making up a straw man argument. Not even what I said.
2. Yes, 150 times the energy extraction of Thorium out of the ground vs U-238 out of the ground. You have a habit of twisting my words in to straw man arguments and “proving” something wrong that is not what I said. Nor what the facts are.
3. Uranium being more abundant than thorium? Not even. ONCE AGAIN, you’ve twisted my statement – which in this case didn’t even MENTION Uranium. In terms of reserves right now, yes, more uranium – in terms of weight or volume. Yet with only 0.7% accessible energy out of U-238, those U-238 reserves don’t deliver much energy vs even the lesser thorium reserves. As to abundance in the earth’s crust, look it up on any chart of abundance of elements in the earth’s crust – more thorium than uranium, and the vast bulk of the uranium is U-238 – USELESS as a fuel, but the raw material for U-235. There are also vast areas of the Moon that are known to have thorium.
4. Using LFTRs to burn up existing nuclear wastes – “So can any reactor if you add enough reactivity.” So, the question is, then, why are we not “adding reactivity” to light water reactors instead of filling up Yucca Mountain? LFTRs will – WILL – burn up our nuclear wastes, once they come on line – and get more energy out of them than we got the first time around in light water reactors. Are you going to say that is a BAD thing???
5. “And a similar sized ball of Uranium has even more energy.” WHICH kind of uranium? And if it is true about U-235, why are we not extracting 99%+ energy out of it? Why do we have such large quantities of nuclear waste now? You, being a nuclear engineer, must know that the ONE big negative about light water reactors is the nuclear waste and what to do with it. Wouldn’t you WANT those wastes used up instead of contaminating the planet? Why can we not USE more energy. It isn’t how MUCH energy, it is how much USABLE energy. Don’t be comparing U-235 with a ball of thorium. Compare a ball of U-238 to the ball of thorium – and it is no contest.
6. Re sizing reactors up or down: “Yep. and the only reactor to kill an American (SL1) was a “portable” Army reactor that suffered a control rod removal prompt criticality steam explosion that killed the 3 operators.” Mein Gott, your logic fallacies know no end. So ANY small reactor is more dangerous, is that your argument? And no reactor in Chernobyl ever killed anyone, right? We can only include American reactors? Is that your argument? The SL1 meltdown could not have happened with a LFTR. PERIOD. Educate yourself on LFTRs and then get back to me.
7. Re reactor construtcion costs: “Reactor construction costs of about $600 million (at current efficiencies) vs $20-40 billion (depending on cost overruns) for light water reactors.
Until the lawyers get active.” Is that supposed to be a rebuttal? Why don’t you just say, “My dad can beat up your dad”? Or “Your mother wears combat boots”?
8. Re instant shutdown: “Almost all reactors have the instant shutdown – it is called the SCRAM switch. The problem is that the daughter fission fragments continue to produce about 7% power levels from delayed neutrons so you can not just walk away (unless you have zilch power history) And Thorium has the same daughter fission fragments as Uranium or Plutonium.” 7% still putting out power – is that your idea of being shut down? WOW. As you said, “The problem is…” NO. These guys shut the reactor down and went HOME – no worries about meltdowns or 7% still cranking. If my 140 mph car is shutdown to 7% it is still going 10 mph. Is that being “shut down”? Not in any book I know.
9. No, Pu-239 was not cheaper. And IS not cheaper than U-233. When the first LFTR since the 1960s is built, it will make more U-233 in weeks than the amount of Pu-239 that has been made in over 60 years. It took a LOT of processing to even make the FIRST plutonium. Think Hanford. What you mean to say is that, having MADE the Pu-239, it was lying around and more available. And that took the entire Hanford processing plant – which cost HOW many billions of dollars in today’s dollars and how much energy expenditure?
With umpteen countries working on FTRs and not even the Americans really putting effort ONE into SUBs, lets make a bet as to which is online first.
There ARE no control rods in LFTRs. Get control rods out of your head. They are yesterday’s tech. Weinberg saw the advantages of liquid nuclear fuel way back in the ’50s. He just couldn’t out vote the military, so none of this has seen the light of day until the Chinese visited Oak Ridge by the thousands, and the world had to ask what is it that the Chinese see that we don’t?
Whether you and your American nuclear engineer buddies want it or not, or fight it or not, it is out of your control.
LFTRs are coming. You guys should be the ones volunteering before Congress to get an American one up and running. I wish to hell you all WOULD.

We differentiate between uranium fueled reactors and Plutonium fueled reactors (and mixed fuel reactors). So even though the fissile material comes out of the ground as uranium (235/238) and is then converted into U235 and plutonium239, by your logic it should all be classified as a uranium reactor. Make up your mind and lets be consistent.
****
Earl, just because you worked with light water reactors doesn’t mean that you know what is going on with LFTRs unless you’ve educated yourself about LFTRs – specifically..
After my work with the Navy I was back in graduate school where I specialized in high energy chemistry — which just happens to include the molten salt reactors. We had a very extensive library on the research results of the molten salt breeder programs., as well as our own work on molten fluorides. I have read more primary research reports than you have even seen (I know because a lot of what I read was classified)
********
1. No, the energy producing SYSTEM cannot be exploded. You are talking about something other than the reactor. You are making up a straw man argument. Not even what I said..
Part of the design with the molten salt reactors is an on site reprocessing facility which would allow concentrating the U233. The U233 can then be used to make your bomb. Simple and efficient. Actually more efficient that the Plutonium separation at Hanford because there is no need to chop up the fuel rods and dissolve them in acid. Any nuclear engineer knows that a functioning nuclear reactor can not be made to yield a nuclear explosion (but you would be surprised how devastating a mere 2000 % power excursion can be). But we all know that you can take a military reactor (using weapons grade uranium235) chop it up and make a number of nuclear weapons from the fuel. Your “thorium” reactor has much larger amounts of what could be classed as weapons grade U233. The detonation of the U233 weapons proves it can be done.
*******
2. Yes, 150 times the energy extraction of Thorium out of the ground vs U-238 out of the ground. You have a habit of twisting my words in to straw man arguments and “proving” something wrong that is not what I said. Nor what the facts are.
The point is that the U238 is discarded solely because of political decisions. (and only by the US — other countries have reprocessing facilities) Until Carter put a stop to it we had promised the electric companies that we would construct and operate a repossessing facility to make use of all the energy in all the isotopes. The failure of the government to keep its word is why we have all the high level waste just sitting around (and why the nuclear industry is so uneconomic)
*********
3. Uranium being more abundant than thorium? Not even. ONCE AGAIN, you’ve twisted my statement – which in this case didn’t even MENTION Uranium. In terms of reserves right now, yes, more uranium – in terms of weight or volume. Yet with only 0.7% accessible energy out of U-238, those U-238 reserves don’t deliver much energy vs even the lesser thorium reserves.

There are also vast areas of the Moon that are known to have thorium.
The critical issue is available reserves. Any geologist can explain that overall crustal abundance does not equate with extractable reserves. The Naval reactors Facility in Idaho is sitting on one of the worlds largest thorium deposits. It has never been developed and frankly it was a major pain, giving off enough radon to trigger our alarms several times a week. (those alarms are sensitive, I once followed a shipyard worker who caused a major radiation leak evolution. He had a unburned Coleman lantern mantel in his wallet which set off all the alarms. Culprit was the small amount of Thorium salts to increase the brightness once burned)
*********
4. Using LFTRs to burn up existing nuclear wastes – “So can any reactor if you add enough reactivity.” So, the question is, then, why are we not “adding reactivity” to light water reactors instead of filling up Yucca Mountain? LFTRs will – WILL – burn up our nuclear wastes, once they come on line – and get more energy out of them than we got the first time around in light water reactors. Are you going to say that is a BAD thing???
Nope, you just ignore the fact that politics says that “THOU SHALT NOT HAVE REPROCESSING”. Without that commandment the uranium 238 is back in the game. (and you get to have your own reprocessing as part of your reactor)
*********
5. “And a similar sized ball of Uranium has even more energy.” WHICH kind of uranium? And if it is true about U-235, why are we not extracting 99%+ energy out of it? Why do we have such large quantities of nuclear waste now? You, being a nuclear engineer, must know that the ONE big negative about light water reactors is the nuclear waste and what to do with it.

Don’t be comparing U-235 with a ball of thorium. Compare a ball of U-238 to the ball of thorium – and it is no contest.
See the issue with reprocessing facilities above.

The SL1 meltdown could not have happened with a LFTR. PERIOD. Educate yourself on LFTRs and then get back to me.
The problem with SL1 was the fact that a single man, manually lifting a totally inserted control rod was able to insert enough reactivity, AND RATE OF CHANGE IN REACTIVITY to give prompt criticality. This was not a problem with the basic uranium issue, it was a problem of the reactor being so SMALL that a small change in reactivity was capable of a massive percent change. SMALL is ultra dangerous.
**********
7. Re reactor construtcion costs: “Reactor construction costs of about $600 million (at current efficiencies) vs $20-40 billion (depending on cost overruns) for light water reactors.
Until the lawyers get active.” Is that supposed to be a rebuttal? Why don’t you just say, “My dad can beat up your dad”? Or “Your mother wears combat boots”?
Talk to any expert on reactor economics, the actual construction costs are minor. The problem is getting through all the permitting steps, and that is where the lawyers live. Naval reactors are expensive because of their small size, but are not even in the same league as power plant costs per MW because of the lawyers.
*********
8. Re instant shutdown: “Almost all reactors have the instant shutdown – it is called the SCRAM switch. The problem is that the daughter fission fragments continue to produce about 7% power levels from delayed neutrons so you can not just walk away (unless you have zilch power history) And Thorium has the same daughter fission fragments as Uranium or Plutonium.” 7% still putting out power – is that your idea of being shut down?

Is that being “shut down”? Not in any book I know.
Sorry to educate you but the issue is not the source of the fuel. It is a matter of the fission fragments. Your U233 fission and a U235 fission produce the same fragments. It is the 7% of neutrons that are delayed that allow you to differentiate between a nuclear detonation and a controllable reactor. It is the difference between reaction times having to be 10E-12 seconds and several seconds. So your thorium reactor will have the same delayed neutrons (and consequent 7% power level) as any other reactor. These fragments rapidly decay so after a day you are no longer at measurable power levels, but the decay can take decades to reach near zero levels.
At a 2MW power level the heat conduction through the walls would be enough to prevent any temperature rise. Research reactors (such as current thorium systems) and Power reactors have different engineering problems.
*********
9. No, Pu-239 was not cheaper. And IS not cheaper than U-233. When the first LFTR since the 1960s is built, it will make more U-233 in weeks than the amount of Pu-239 that has been made in over 60 years. It took a LOT of processing to even make the FIRST plutonium. Think Hanford. What you mean to say is that, having MADE the Pu-239, it was lying around and more available. And that took the entire Hanford processing plant – which cost HOW many billions of dollars in today’s dollars and how much energy expenditure?
It takes one absorbed neutron to make U238 go to Pu239. It take one absorbed neutron to make Th232 go to U233. A U233 fission produces LESS neutrons than a U235 (or Pu239) fission. So QED a thorium/U233 reaction is more expensive than a U238/Pu239 reaction simply because it takes more fissions to produce the same amount of new fissile material
**********
With umpteen countries working on FTRs and not even the Americans really putting effort ONE into SUBs, lets make a bet as to which is online first.
I will grant you that with zero effort in nuclear reactors the US is going to fall far behind, the Environmentalists are killing US. But please note that all these great programs are being carried out with reactors that are only rated at 2 MW, just a little bit higher than the power used by our LiBr salt air conditioner on my sub.
*******
There ARE no control rods in LFTRs. Get control rods out of your head. They are yesterday’s tech. Weinberg saw the advantages of liquid nuclear fuel way back in the ’50s. He just couldn’t out vote the military, so none of this has seen the light of day until the Chinese visited Oak Ridge by the thousands, and the world had to ask what is it that the Chinese see that we don’t?
Get Murphy’s law firmly in your mind. Yes I know that you can use thermal expansion properties to control power levels. My first reactor did just that. But you may be interested in what we called … [details trimmed. 8<) Mod] … Similar exercises are left for the ingenuity of future nuclear engineers on a thorium system.
And then I suggest you look up the issue of plating / chemical hide out in multi salt systems. Much like your hot water heater you can form deposits of salts on surfaces. Interesting effects occur if those salts happen to be fissionable. We are not talking about going boom, just melting critical components (which are already stressed by high temperature corrosive salts). Homogeneity is a problem with just about any salt system with cycling temperatures. Look at eutectic salt heat storage systems that fail after a few hundred cycles.
*********
The world of engineering is not simple. Wishes do not necessarily come true. And note we have been working on molten salt reactors for over 60 years, publishing our research for all to read. Just like the Soviets were able to build nuclear weapons after reading our research notes (still classified) in just a few years and the Smyth report which pointed out all the missteps we made, the world has the chance to take all our efforts and produce a working system, maybe.

I want submarine-sized reactors for Oregon, Washington, and Idaho. That way we can have all the electricity we need, and retrofit the dams for better fish migration, flood control and irrigation purposes. We could bring Snake and Columbia River waters to many more places and substantially increase food production if it were not being used for power generation.
@Albert Whiteman Smith –
“So even though the fissile material comes out of the ground as uranium (235/238) and is then converted into U235 and plutonium239, by your logic it should all be classified as a uranium reactor. Make up your mind and lets be consistent.”
Except that the U-238 is never EVER introduced into the reactor at all. Thorium IS. Your logic says that the bread into the body is first taken and refined and refined and refined and refined externally for weeks and months before being eaten as some other material. As I said, pedantic point.
“We had a very extensive library on the research results of the molten salt breeder programs., as well as our own work on molten fluorides. I have read more primary research reports than you have even seen”.
Any of it relating to thorium?
“Part of the design with the molten salt reactors is an on site reprocessing facility which would allow concentrating the U233. The U233 can then be used to make your bomb. . . . Your “thorium” reactor has much larger amounts of what could be classed as weapons grade U233. The detonation of the U233 weapons proves it can be done.”
From footnote 6 in Wikipedia article on U-233:
Yes, everyone needs nukes that may pre-detonate.
2. “The point is that the U238 is discarded solely because of political decisions. (and only by the US — other countries have reprocessing facilities) Until Carter put a stop to it we had promised the electric companies that we would construct and operate a repossessing facility to make use of all the energy in all the isotopes. The failure of the government to keep its word is why we have all the high level waste just sitting around (and why the nuclear industry is so uneconomic)”
And if you had your way, what percentage of the available energy could and should be extracted? You are saying that, though some “high” level could be extracted, we are just throwing several times of the energy down the drain? And this wasn’t happening in the 25 or so years before Carter? And Reagan and Bush and Carter, etc., never undid Carter’s decision? And how much re-processing did this entail? How much cost? With how much reduction in net energy?
Thorium’s “re-processing” happens simply by flowing in a jacket past the core and then removing the Xenon, and then essentially letting it sit while it re-processes itself. Oversimplified here, but essentially that is it.
3. “The critical issue is available reserves. Any geologist can explain that overall crustal abundance does not equate with extractable reserves. The Naval reactors Facility in Idaho is sitting on one of the worlds largest thorium deposits. It has never been developed…”
Of course overall abundance is not in itself sufficient. But when India and the U.S. and China have large identified it means they specifically know where to go to get it. And the fact that thorium has so far been considered waste byproducts and we are sitting on it, that means that we DO know where to go. Extractable? Yes. They are sitting on it WHY? Because thre currently is no use for thorium. Of course, when LFTRs and other types of thorium reactors come online, thorium will no longer be a waste material. Not only that, thorium reserves will grow as it becomes a non-waste commodity – because the geologists will go out looking for more. That is what happens with oil (and happened with uranium); there is no reason to think that won’t happen with thorium.
For a U.S. thorium deposits map see http://en.wikipedia.org/wiki/File:NAMrad_Th_let.gif
4. (Re: Burning up existing nuclear waste in LFTRs) “Nope, you just ignore the fact that politics says that “THOU SHALT NOT HAVE REPROCESSING”. Without that commandment the uranium 238 is back in the game. (and you get to have your own reprocessing as part of your reactor)”
What does that have to do with thorium LFTRs being able to use up wastes? If they’ve chosen to do or not do something with U-235 in the U.S., what does that have to do with thorium LFTRs being used all around the world? U.S. decisions on U-235 – a moot point as far as China and India and others are concerned.
From the Molten Salt Reactor Experiment (MSRE) page at Wiki: “Additions of uranium and plutonium to the salt during operation were quick and uneventful…” In other words, as far as things stand right now, my statement stands un-rebutted.
5. Re: a ball of thorium having more or less energy than (an E.S. unspecified type of) “uranium”: First of all, it doesn’t rebut the orignal attatement that that sized ball of thorium is a lifetime of energy for one person. The U-235 or U-238 points you make are tangential, at best.
You don’t rebut my point. You just run off in your pro-uranium direction, which is entirely beside the point. And what is the point? That LFTRs are coming, and there is NOTHING that is going to stop them – unless it is some as-yet-uncovered insurmountable technical problem with thorium LFTRs themselves. Is that problem going to happen? Possibly. So far, nope. Reading several more things on LFTRs today, it sounds more and more like getting from here to there is “merely” hands-on development and engineering. I say merely because it is still going to take many man-years to get the first one up and running. But there really are no technical problems, just developing pilot reactors (for hands-on) and then sizing them up to full scale (multi-GW).
6. “The problem with SL1 was the fact that a single man, manually lifting a totally inserted control rod was able to insert enough reactivity, AND RATE OF CHANGE IN REACTIVITY to give prompt criticality. This was not a problem with the basic uranium issue, it was a problem of the reactor being so SMALL that a small change in reactivity was capable of a massive percent change. SMALL is ultra dangerous.”
I take your point. Yet that reactor was capable of a meltdown – which is what happened. A LFTR is not. If it overheats the reactions slow down due to expansion and even from planned overflow. IN ADDITION, there is the freeze valve. If you don’t know what that is, look it up.
You are pointing at, for example, a tree sloth and arguing that horses can’t run. Apples and oranges. Or maybe a better analog would be internal combustion engines versus diesel. Problems with one do not necessarily translate to the other. And in this case, I argue that your point is moot.
7. Costs: Tens of billions versus <$1B – you minimize this apparently simply because you are so pro-uranium. You just keep raising bars and lowering bars, depending on which favors uranium (and the career you have invested in uranium). Like billions don't matter if they are spent on uranium. It's called "Confirmation bias" – in which anything favorable to your side is given an easy pass, and everything favorable to the competitor (thorium) has the bar raised as high as you need it to, in order to tell everyone it will fail.
You've got a sliding standard, Earl. And nothing you've said argues that thorium is not going to be coming down the road.
ALL technologies get replaced in their time. The horse and buggy, propeller airliners, 8-track tapes, VHS, CDs, steam automobiles. So don't hyperventilate about light water reactors eventually going extinct. Do not imagine that light water reactors will always be the end-all and be-all of nuclear power. In its time thorium will possibly be replaced, too – though with only three elements capable of being the fuel for reactors, maybe not. Or perhaps LFTRs (as opposed to thorium) is what will be replaced eventually.
8. "Research reactors (such as current thorium systems) and Power reactors have different engineering problems."
There ARE no current thorium LFTR systems. As to different problems, I've worked as an engineer in R&D (7 years) and on many full-bore production machines, and this principle is true, not just for nuclear plants. However, if you read up on the MSRE, you will see that they didn't just sit on their hands – they ran experiments and trials to identify problem areas for upscaling to full size. Yes, other problems will come up – but they are, by and large, engineering problems, meaning that the science is proven and it is up to engineeers to work out the technical details. Will they have problems along the way? OF COURSE. How many problems came up in developing light water reactors? The will existed to push through those problems and to solve them. Such will be the case with LFTRs, too.
But you have to remember this: It is not the U.S. working on this. The other countries will solve the problems, and then the U.S. will have to buy the technology. You and your cronies have no say in this.
"It takes one absorbed neutron to make U238 go to Pu239." That is why it takes the gazillion dollar Hanford plant to make plutonium, then? To add one neutron?
"It take [sic] one absorbed neutron to make Th232 go to U233." That is obvious, yet I quote from above: “Separation of the uranium-232 from the uranium-233 proved to be very difficult and not practical.”

“There ARE no control rods in LFTRs. Get control rods out of your head.”
Actually, that was a misstatement on my part. (I immediately started talking about liquid fuel, so you can see that I got the two rods juxtaposed and wrote the wrong one down.) There ARE control rods in LFTRs – or at least there were in the MSRE. It is the fuel rods that I meant to point out. My bad. They are not going to use the expansion-cool-down as a primary control. That would not be good engineering at all. They want positive controls, not passive. Even if the molten salts make the reactor more-or-less self-controlling. I certainly wouldn’t count on it. Not without years of experience behind such a decision.
I don’t disagree with your caution about Murphy’s Law, which is why I favor positive controls always. Don’t just start up a LFTR and expect it to manage itself. That would be stupid. I personally DO have a lot of faith in nuclear engineers, that whatever is necessary for good control, they will deal with it and solve it.
And perhaps there IS a minimum sized LFTR, below which the reactivity is too touchy. Good! Then designs will give some wide service factor on size and go no lower. However, the 7Mw MSRE was not, apparently, too small, and that would make an awfully small online reactor. The $600M price tag above was based on a 1Gw reactor. Between 1Gw and 7 Mw is a wide range for smaller reactors.
At the same time, look at how consciously and intentionally you had to TRY to sabotage your S5W.

“And then I suggest you look up the issue of plating / chemical hide out in multi salt systems. Much like your hot water heater you can form deposits of salts on surfaces. Interesting effects occur if those salts happen to be fissionable. We are not talking about going boom, just melting critical components (which are already stressed by high temperature corrosive salts).”
Good points, and ones I have not read up on as much as I would like. However, let’s let Wiki speak here (footnotes removed but available on the Wiki page for MSRE):
“A low chromium, nickel–molybdenum alloy, Hastelloy-N, was used in the MSRE and proved compatible with the fluoride salts FLiBe and FLiNaK. All metal parts contacting salt were made of Hastelloy-N…
…At the time that design stresses were set for the MSRE, the data that was available indicated that the strength and creep rate of Hastelloy-N were hardly affected by irradiation. After the construction was well along, the stress-rupture life and fracture strain were found to be drastically reduced by thermal neutron irradiation. The MSRE stresses were reanalyzed, and it was concluded that the reactor would have adequate life to reach its goals. At the same time a program was launched to improve the resistance of Hastelloy-N to the embrittlement.
An out-of-pile corrosion test program was carried out for Hastelloy-N which indicated extremely low corrosion rates at MSRE conditions. Capsules exposed in the Materials Testing Reactor showed that salt fission power densities of more than 200 W/cm3 had no adverse effects on compatibility of fuel salt, Hastelloy-N, and graphite. Fluorine gas was found to be produced by radiolysis of frozen salts, but only at temperatures below about 100 °C.
Components that were developed especially for the MSRE included flanges for 5-inch (130 mm) lines carrying molten salt, freeze valves (an air-cooled section where salt could be frozen and thawed), flexible control rods to operate in thimbles at 1200 °F (650 °C), and the fuel sampler-enricher. Centrifugal pumps were developed similar to those used successfully in the aircraft reactor program, but with provisions for remote maintenance, and including a spray system for xenon removal. Remote maintenance considerations pervaded the MSRE design, and developments included devices for remotely cutting and brazing together 1½-inch pipe, removable heater-insulation units, and equipment for removing specimens of metal and graphite from the core…
…One unexpected finding was shallow, inter-granular cracking in all metal surfaces exposed to the fuel salt. The cause of the embrittlement was tellurium – a fission product generated in the fuel. This was first noted in the specimens that were removed from the core at intervals during the reactor operation. Post-operation examination of pieces of a control-rod thimble, heat-exchanger tubes, and pump bowl parts revealed the ubiquity of the cracking and emphasized its importance to the MSR concept. The crack growth was rapid enough to become a problem over the planned thirty-year life of a follow-on thorium breeder reactor. This cracking could be reduced by adding small amounts of niobium to the Hastelloy-N.”
All in all, I am glad to have this discussion with you. You have not really rebutted any of my original points, though you may think so. You diverted to straw man arguments, and then when it came down to brass tacks, all you did was make confirmation bias arguments in favor of uranium and tried to nitpick against thorium. I still see nothing ahead but development and engineering to be done for LFTRs – and no even slightly insurmountable problems.
The closest you came IMHO was on the proliferation issue, but the U-232 contamination issue simply shoots that down. No one in their right mind would make a nuke that might pre-detonate.
@Magma
could you please try posting something of substance for a change?
In general those who call any new energy source “free” are activists, and are playing very fast and loose with their terms. Real engineers and planners would blush to make such a claim.
The second test for an activist is the insistence on getting rid of coal and oil as a necessary step in bringing a new technology into use. There is no reason why energy, transportation, shipping, and home use should come from one source. For example, placing cars and trucks as a new demand on the electrical grid is on its face undesirable, unreasonable, and full of unforeseen consequences and costs.
Energy sources should be diversified further, and include coal and gas. The electrical grid is far too vulnerable to be relied on for transportation and shipping. The greatest danger to the grid is government control through remote access and smartmeters, rationing, and instabilities introduced by “renewables.”

Agreed. Look at Zeke’s post, for example. That is substance. None of Magma’s come close.

(continues the sermon)
What you seem to ignore is the fact that I was working on the issues associated with Molten Salt Breeder Reactors 40 years ago. What do you think my work in fluorine systems was directed towards? You seem to think that the issues of corrosion etc were solved. They were NOT. They were merely reduced to an “acceptable” level that we HOPED would prevent the formation of large holes in the reactors. (the problem was not Thorium or Uranium – it was the salts themselves NaF and KF are nasty at high temperatures)
I am in favor of both Thorium and Uranium/Plutonium reactors.
What I was pointing out is Thorium is NOT the Holy Grail.
The biggest idiocy in the Acolytes of Thorium is their insistence that it is bomb proof, proliferation proof, and a panacea.
As you noted U233 as a weapon was hindered by the presence of U232. U233 from Thorium would be (relatively) free of U232 so it would be a better source for the fission core of a thermonuclear device. Thorium would make the risks even greater than they are today.

Of course, idiot. Nuclear engineering is not limited to only studies of Uranium.

Yes, everyone needs nukes that may pre-detonate.
Actually having pre detonation problems would mean that you only have a fizzle not a boom. Much less damage experienced. From a non military point of view squib yields are nice.

Who said Reagan and Bush were good guys? In fact I would class them as more evil, simply because they pretended to want to halt the Socialist progress while actually compromising They all just acquiesced to the enviro nuts who wanted to kill ALL nukes (as well as coal, natural gas, and hydro). Reprocessing would allow full use of the U238 being converted to Pu239.
*******
Thorium’s “re-processing” happens simply by flowing in a jacket past the core and then removing the Xenon, and then essentially letting it sit while it re-processes itself. Oversimplified here, but essentially that is it.
Xenon is not a problem it is a feature. No removal system would ever be designed to handle the 24 hour poison, you simply burn your way through it. Costly in neutrons for a breeder budget but that is life. The same “simple” reprocessing can describe a U238 /Pu239 process. you could just use the molten salt system, or remove the fuel rods for a month. The complications only occur id you want to separate the Pu239 / U233 for weapons use.
******
Engineering is the art of taking scientific discoveries and moving from the bench scale to pilot plant to prototype to commercial. Thorium and molten salt systems are still at the bench scale, and have been for over 60 years. We are just a little bit ahead of fusion plants which have been in the works for the same period, with roughly the same success. The same promise of “FREE” energy is made, they just neglect all the extra problems like radiation effects on the plants. (Fusion produces more radiation not less per MEV of energy produced)

OK, you have a mass of molten salt that is undergoing out of control excursions. And you actually expect a freeze plug (at the bottom no less) to make a timely melt to spread the components all over the floor (oh what a radiological mess) It is like expecting the oceans to heat up the deep waters from their 4C temperature by heating the surface. Hasn’t happened in 4 billion years.

“It takes one absorbed neutron to make U238 go to Pu239.” That is why it takes the gazillion dollar Hanford plant to make plutonium, then? To add one neutron?
Yep. Transmutation of the elements is not cheap when you have to scale up by an Avogadro factor.
***
“It take [sic] one absorbed neutron to make Th232 go to U233.” That is obvious, yet I quote from above: “Separation of the uranium-232 from the uranium-233 proved to be very difficult and not practical.”
So you ignore the danger associated with proliferation associated with isotope separation U233 and prefer lower cost Thorium transmutation U233 that would no longer have the drawbacks associated with a U233 bomb.

You obviously do not realize that control rods are at best a TERTIARY control and probably a Quaternary control.
First you have the delayed neutrons effect which moves you out of the nano second reaction time zone.
Secondly you have the thermal protection effects of expansion in both water and salt systems
Thirdly you have the physical dispersion effect of not allowing a concentration of fissiles to occur (China Syndrome)/ Fukushima
Fourthly you have the installed neutron adsorbing rods
and Fifthly you have total system poisoning with Boron.
You best have all five available or you are tightrope walking without a safety net.

Oh ye of great faith. Experience will teach you that the most dangerous phrase is ” I have taken all eventualities into consideration” Engineering is advanced by massive disasters and many dead bodies.
*******

No, that was just the funniest way to sabotage. There were many much quicker methods that were mentioned in my qualifications exams. Together with the one they had not anticipated. The life of a reactor operator is hours of boredom punctuated by seconds of sheer terror. And the most dangerous words an officer can say are “:I relive you, sir”
Since this is a CO2 related board I will give you an example of deadly effects of that horrid gas. My sub was only a couple years old when we discovered that we were only a short time away from a monumental disaster. The CO2 on a sub is removed by an amine extraction system and then dumped overboard. We discovered just a couple years after launch that the CO2 we were dumping into the exhaust of a sea water cooling system was altering the pH enough that the piping was already eaten 50% away. And this was after 6 decades of designing and building submarines and working for the safest systems possible.

You are ignoring the issue. I gave an example of the Glauber Salt crystallization problem. (Homogeneous mixture of Na2SO4 decahydrate) after a number of freeze cycles it separates into components which no longer provide the thermal fusion properties. Molten salts do no maintain a homogenous characterization when undergoing temperature cycling and especially crystallizations. You nice uniform mix of NaF KF and (Ufx / ThFx) will not stay uniform after a few crystallizations (shutdown/ cool down) . You will end up with undissolved concentrations of fissionables in the worst places.

The closest you came IMHO was on the proliferation issue, but the U-232 contamination issue simply shoots that down. No one in their right mind would make a nuke that might pre-detonate.
Repeating. The U232 issue only applies to natural uranium sourced U233. Thorium sourced U233 is free of U232 and thus makes a better bomb. (still not a good bomb, but better than available). Blowups Happen.
It is the general case that in these videos denying global warming that no actual climate scientists are ever involved in their making. While it is true that In The Last Year Of His Life, Roger Revelle’s name was attached to a paper that had already been written and published By Fred Singer downplaying global warming, to leave the story there is entirely misleading.
Revelle’s daughter wrote:
“…Roger Revelle—our father and the “father” of the greenhouse effect—remained deeply concerned about global warming until his death in July 1991. That same year he wrote: “The scientific base for a greenhouse warming is too uncertain to justify drastic action at this time.” Will and other critics of Sen. Al Gore have seized these words to suggest that Revelle, who was also Gore’s professor and mentor, renounced his belief in global warming. Nothing could be further from the truth.”

You deniers always have to twist facts and quotes a little to make your case. How come?

The global warming scare has always been with us. It just comes and goes. Same with global cooling.
Now please pay attention Barbra & Jack Donachy, this is how it’s done. I don’t ask people to simply Google something I assert, well not 97% of the time. 😉
All I see on your blog is FOOD, FOOD, FOOD and a few icicles. Alaskan temperatures have been trending down since 2000. Please get out of your tent and have a life. Sheesh! A few days of a warm January is not unusual or a sign of global warming. Did you complain during the last Alaskan winter. Brrrrrrrr.
