    I continue to conclude: It's not Chernobyl. When all this began I said a worst case would be one or more Tsar Bomba equivalents. We now know it is far less than that. It does not appear that the entire mess will equal one Chernobyl.

    There will probably be a greater and more fatal impact: the rejection, in the West, of nuclear power, which will either have dire economic consequences and lead to even more transfer of wealth into the sovereign investment funds of the Near East, or possibly to wars: I point out that our Middle East Wars have been deadly; nuclear power has not directly killed anyone in the United States. There are debates about "extra" cancer cases caused by nuclear power, but I know of no proof that there have been any.

    Note that China is not going to halt nuclear power construction. The major effect of Fukushima Daiichi may well be a very great Chinese comparative advantage. Cheap easily available energy and freedom are the keys to economic prosperity: the Chinese are moving toward both. The United States is moving away from both. The results are predictable.

    Meanwhile, there is no sign of any danger to anyone outside the evacuation zone in Japan, and indeed not much evidence of danger inside it. Japan will be deprived of some rice farming land for a few years -- perhaps -- and of the energy from the plant. Of course the plant was older and scheduled for retirement to begin with.

    The difference betweent fission, fusion and geothermal is that geothermal requires no fuel creation or elimination. You dig two deep holes fairly close together and force water down one of them. The heat of the Earth heats the water, which comes up the other hole - usually as steam or superheated water that will become steam when the pressure is released, but sometimes just as much hotter water. Naturally after the energy gained is tapped, the hot water is then re-injected. For new water some use sewage effluent and solve two problems at once. There is no ash, no spent fuel to rot in casks 100,000 years under close supervision of a non-proliferation task force. There are no mining deaths because there's no mine.

    Actually, thus far every design type of theoretical fusion plant would necessarily create radioactive waste, although not as much of it as fission plants. The reason is the same one that the waste-water in the original article is a problem: nuclear reactions work by massive cascades of nutrons randomly hitting atoms in the core. When those nutrons hit the nucleus of an atom (in a way that causes them to be absorbed in the right way), then you get your nuclear reaction, and that in turn produces more neutrons as ersatz-billiard-balls to continue your reaction, plus energy (in the form of heat) that you harvest off (usually with water) to convert into your power-transmission method of choice (usually electricity).

    The problem in all of this is that you can't just limit it to your fuel and your energy harvester (water), you wind up with lots of other elements in the reaction chamber that also get bombarded with neutrons. And some percentage of those elements are going to wind up transmuting into radioactive waste.

    In the case of a fusion reactor that is probably going to be whatever serves as the reaction chamber wall. Remember, neutrons are magnetically/electrically neutral particles, so you can't contain them using magnets, so you just have to let your reactor wall take the hits, and slowly degrade into radioactive waste. No one has a solution to this problem, and it is unlikely that one exists.

      RTGs do not produce much external radiation - they are based on alpha-emitter material that is absorbed by the surrounding shielding converting radiation into heat. However, space hardware is rad-hardened because of cosmic rays - natural radiation present in space. This is often not as high-level as can be found near reactor core.

    Then try to drive that remotely. The name "radioactivity" is not there in vain. It really creates horrible noise in all radio frequencies, so forget "fly by radio" models. Either it's autonomous, or driven by cable, or you set up a goddamned 100KW radio tower for driving your drone to overcome all the noise.

    And then you got a ground drone with all electronics shielded by an inch of lead, driven by a mile long spool of cable unwound from a roll on the back. Now give it a camera that can still see the outside and won't crash due to radiation - possibly analog, with only the CCD exposed, and in such a way that radiation won't pass inside bypassing the lenses. Give it a manipulator arm that has all electronics shielded. Give it a battery that will be able to drive the half a ton of lead, 100kg of wire, and another half a ton of hardware of the device - forget your fancy micro engines, every exposed part must be thick rugged so that electric noise doesn't affect it. Make sure it's radiation-leak proof, because even a small hole in the shield may crash the software.

    And now build it. How long will it take you to do it?

Over the lifetime of a fusion plant you'd end up with barely enough high level waste to put into a small oil drum - this can then be destroyed. People seem to forget that you can use the huge neutron flux of a fusion reactor to transmute materials, ie you can convert dangerous radioactive waste into much more benign waste. It would require a dedicated plant, but this would be no problem in a fusion economy.

    This is typical and normal for Japanese companies not to be forthcoming with information. They simply don't offer information unless it is required. You might consider this "secretive" especially when such an event literally has potential to affect everyone on the planet in some way, but this is simply not inherent to the way the Japanese think. This is an embarrassment and simply would prefer not to talk about it. I think this trend is clear and obvious from the very beginning of the reporting of the situation. The picture painted was always one indicating "nothing to worry about" and so on. As things progressed, they had to "admit" more failure as it couldn't be denied.

    In the western mind, this does the opposite of "building trust" and is read as being deceptive. Even now, I cannot help but feel that way.

  29. Jerry Pournelle's *uninformed* view of Fukushima by MrKaos · · Score: 4, Insightful
    Clearly Pournelle's research is inadequate.

    I continue to conclude: It's not Chernobyl. When all this began I said a worst case would be one or more Tsar Bomba equivalents. We now know it is far less than that. It does not appear that the entire mess will equal one Chernobyl.

    Rubbish, Tsar Bomba's fall out is measured in kilograms, Chernobyls around 10's of tons. Due to the spent fuel pools there is approximately 30-40 years worth of spent fuel at Fukushima and we could be looking at around 800-1000 tons of plutonium assuming a 10 year refueling cycle. Great that it didn't blow up however the release of radionuclides will continue to occur until all the leaks are repaired. The question is how this will be achieved. Chernobyl released it's radionuclides into the air and all over the land because it was land locked. It seems that because Fukushima is releasing its radionuclide yield into the ocean that this is somehow less concerning. Let's do and see the science and asses the actual damage based on that, not hyperbole.

    There are debates about "extra" cancer cases caused by nuclear power, but I know of no proof that there have been any.

    The claim can be made for two reasons. First at TMI the science wasn't even done. Dr Carl Johnson, an expert in radiation related diseases asked the NRC and DOE to do a survey to look for some of these elements in the respirable dust around TMI after the accident and they refused. So if the authorities *refused* to take measurements on which to base long term cancer studies can be based, how can a supposition be made about how many lives have been lost due to increased cancer rates?

    It can be best summed up by this 2004 quote of Dr Michael Fernex formerly of the University of Basel who worked for the WHO;

    "Six years ago we tried to have a conference. The proceedings were never published. This is because in this matter the organisations at the UN are subordinate to the IAEA. Since 1986 the WHO did nothing about studying Chernobyl. It's a pity. The interdiction to publish which fell upon the WHO conference came from the IAEA. The IAEA blocked the proceedings; the truth would have been a disaster for the nuclear industry"

    Here is the actual text of the agreement. However the UNICEF report "Human consequences of the Chernobyl nuclear accident" summarised it neatly;

    "Life expectancy for men in Belarus, Russia and Ukraine, for example, is some ten years less that Sri Lanka, which is one of the twenty poorest countries in the world and is in the middle of a long drawn out war"

    Maybe Pournelle is just to lazy to look and since cancer takes years to gestate I think it's premature to understand the damage done to the Japanese populace by Fukushima.

    the Chinese are moving toward both. The United States is moving away from both. The results are predictable.

    Absolutely predicable. If they make the same tragic organisational mistakes that every other country has made then we will see an accident on the same scale. It's difficult to believe that the Chinese will succeed where the UK, USA, USSR, Germany and now Japan has failed.
