Japan's Last Nuclear Reactor Shuts Down

AmiMoJo writes "Japan's last active reactor is shutting down today, leaving the country without nuclear energy for the first time since 1970. All 50 commercial reactors in the country are now offline. 19 have completed stress tests but there is little prospect of them being restarted due to heavy opposition from local governments. Meanwhile activists in Tokyo celebrated the shutdown and asked the government to admit that nuclear power was no longer needed in Japan and to concentrate on safety. If this summer turns out to be as hot as 2010 some areas could be asked to make 15% power savings to avoid shortages, while other areas will be unaffected due to savings already made."

      Unlike molten salt reactors, a class of fast breeders utilize liquid sodium, which reacts violently with water- and has been a bit of a problem (very costly) when heat-exchangers, reheaters, and similar equipment fails.

      Molten salt reactors, like the one prototyped at Oak Ridge National Laboratories back in the 60s, ran for years. The corrosion issue stems from the inadvertent production of tritium (from an undesired isotope of lithium in some formulations of the salt) which can combine with the fluorine (Liquid Fluoride Thorium Reactor/LFTR) to produce a strong acid. These and other problems appear to have very viable solutions (from listening to the relevant scientists and engineers), and should not be used to disparage the technology.

      To compare this fission technology that has already been demonstrated in principle with a prototype, to fusion which has not even achieved break-even demonstrates a serious lack of understanding of the issues involved. The primary advantages of the molten salt reactor to energy production are the following:
      - based on fission which is a well-understood phenomena; U-233 liquid-fueled reactor already demonstrated in principle decades ago (found to be very reliable)
      - a liquid fuel system that operates at low pressure and high temperature which allows for very high levels of safety and efficiency
      - the above which contribute to the high likelihood of low-cost reactors
      - low cost reactors will dramatically lower the cost of carbon-free energy
      - high temperatures allow for more efficient cogeneration; example: ammonia synthesis which could be used as an energy carrier on the scale of petroleum, which would address both concerns about fuel supply and carbon emissions
      - high temperatures also allow for the use of dry cooling (as opposed to "wet" cooling which uses a lot of water), necessary for an efficient thermodynamic cycle
      - thorium fuel is about as abundant as lead (3-4 times more abundant as uranium), and so very low cost
      - fissile startup requirements are minimal (less than a tonne of 20% enriched U-235 is possible)
      - system is very proliferation resistant (lots of technical details in the specifics)

      The disadvantages:
      - we must face our fear of nuclear energy
      - more R&D (substantially less than $10 billion) will be required before this technology is a commercial reality
      - bureaucratic and industry resistance to a new technology (they've already committed themselves to something else which is not suited for solving our systemic problems)
      - the general public remains woefully ignorant of the risks it is facing by foregoing nuclear energy

      The potential is that we have a nuclear system that is so safe and efficient that it may have the convenience, but at lower cost, than modern and ubiquitous natural gas plants. We are looking at perhaps the greatest technology humanity has ever developed, at best critical to our transition to a sustainable existence, and at worst, an essential technological step to reduce the risk we currently face. The United States may lack the technical leadership to step into a new era of low-cost carbon-free energy, but its rivals are seriously looking at this approach (China is apparently putting around $100 million annually into this), and if it proves viable on a commercial scale (all signs so far showing absolutely "yes"), the US will be left behind. It is difficult to overstate the importance of this issue to national security. Our economic well-being is dependent upon the cost and convenience of energy, and "farming" low-density energy sources dramatically increases our risk in this area. Lower the cost of energy and you will facilitate wealth creation, otherwise we face recession and decline.

It badly scarred them not only physically but mentally. The recent disaster effectively killed a chunk of the country and Japan already has a shortage of land especially farmland. It may have been smarter to phase it out but the fear of a second such disaster was too great. Japan is fairly new to nuclear power and they are in a unique situation. The country is very active geologically and earthquakes are commonplace and it has a lot of potential for similar disasters. None of us can know the real position they were in. The accident happened because they got sloppy and after reviewing other plants they may have seen shortcomings in the other plants that could have lead to disasters and the upgrades would take too long. I'm just saying there may be more to it than we know and Japan has a lot of pride and it's hard for them to admit they got sloppy. It's easy to say all the disasters are human error but it's impossible to take human error out of the equation. Growing up I heard there would statistically be one disaster every thousand years. If statistics were accurate we would be safe for the next three thousand years. Human error will always be a factor. As costs rise also there's a tendency to cut corners increasing risk. That's what caused the gulf oil spill. All the reactors in this country are rapidly approaching the end of their projected lives and many have already passed it.

In the near term we need all of the sources including coal and oil but a critical part of the puzzle will be that ugly word, conservation. Trust me, the Japanese will be hearing that word a lot over the next few years. Used wisely conservation is a powerful part of the puzzle. Obama got laughed at for suggesting properly inflated tires would save as much oil as the arctic reserve would contribute. As funny as some found it the fact is he was right. If everyone embraced conservation they wouldn't have to change their lifestyles significantly and we could put off new power plants for a decade or more.

But, the two are highly related - that is, there was good reason to be skeptical of promises of safe, long-term operation. A small, compact variation of the Navy's system is being marketed to U.S. communities for local power production at this time, but its adoption is meeting strong resistance in the regulatory agencies and congress due to big power and big energy special-interest influence - i .e. corruption.

    So yes, there is a way to have safe, long-term nuclear power right under our feet and it is only our inept corrupted political system that keeps us from realizing it.

    the trouble with Nuclear is the disasters are so bad, and sooner or later the reactors get privatized and some wealthy jackass cuts funding to safety. Since he doesn't live anywhere near the disaster (or could just move if he did) he's fine. Running a nuclear reactor is very, very expensive. So there's a LOT of money to be made by cutting corners and skipping maintenance. The kind of people who run our world (thanks to the way inheritance works) are not very bright either. Unless safety can be made so cheap that the margins aren't good enough to attract your average capitalist you'll never have 100% safe nuclear power.

      Which is why we don't build very large dams much any more, unless absolutely forced to. Perhaps you can agree that the same logic should apply to nuclear power.

      In a lot of the world, large dams aren't being built because the suitable sites either already have a dam or have a large number of NIMBYs in residence. The geology matters; build in a limestone area, and your reservoir will never hold water as the rock will always be too permeable. (Put the dam itself in a bad area and it will collapse. That's occasionally happened, until everyone learned not to do that, and far more died from that "learning" than have ever died due to nuclear accidents.)

      Look, we don't claim that nuclear power is 100% safe (it clearly isn't) but we do claim that you're putting a falsely low estimate of risk on the alternatives. Remove those rose-tinted glasses!

      Death is not the only consequence of a nuclear disaster. Look at the economic damage and the cost of fixing the problem. A large area of Japan is uninhabitable, a large number of people were displaced and are now jobless and living on benefits just outside the exclusion zone. You can argue all you like about whose fault it is and if the actions taken were justified, but none the less it happened.

      But most of that is due to excessive caution and fear-mongering. If you can't measure the radiation or the chemical pollution, by what possible standard is it unsafe? Mystic karmic vibration disturbance?

      If Fukushima had been a geothermal plant, if instead there had been large off-shore wind farms, even if there had been a coal plant on that very same spot this would not have happened.

      That is true. It is also the case that the pollution produced by that plant's normal operation would have caused many cases of respiratory diseases and low-to-medium levels of chronic poisoning. Furthermore, the cost of importing all that coal (Japan has none to speak of domestically) would have resulted in the Japanese people having significantly less money to spend on other things (such as healthcare, but it's really a long list of missed opportunities). As I said before, take off those rose-tinted glasses; don't just see the downsides of one alternative, look the others fairly too and weigh them all in the balance.

      Your ignorance is showing. The notable fission products released from a nuclear plant accident are 131I, 137Cs, and 90Sr. 131I has a half-life of just over 8 days. In 80 days, it's 1/1000 the level, in 160 days, 1/1M, in 240 days 1/1B. It's a short term hazard.

      137Cs and 90Sr each have a half-life of ~30yrs, making them a factor for up to 600 years. Both are beta emitters, so they're primarily a hazard only when inhaled, ingested, or with direct skin contact. However, 90Sr isn't produced in large quantities, so it's not a major factor. That leaves 137Cs. The main concern with 137Cs is with unknown/untreated exposure. It's easy and fairly cheap to treat exposure (including land) if you know about the contamination. 137Cs and 131I are the primary isotopes released at both Chernobyl and Fukushima.

      So, what about the others. 238U (4.4B yrs) and 235U (700M yrs) in the fuel have such long half-lives and are primarily alpha emitters, such that you can hold them with just gloves.

      Uranium fueled reactors will produce small amounts of 239Pu (24,100 yrs), 242Pu (373K yrs), and 241Pu (14yrs) The 241Pu is the most radioactive of these, but it's produces in much lower quantities than the other two. The other two are less radioactive, and are produced in small quantities. Contrary to urban legend, Pu is not "the deadliest substance known", in fact, the body generally won't absorb it even if eaten (definitely not recommended). The real risk from Pu is if it's inhaled, and still, due to the long half-life of 239Pu and 242Pu, you would have to inhale a notable number of atoms to have any likelihood of increased risk.

      And if you switch to thorium fueled reactors, they produce virtually no plutonium, and no weapons grade uranium. The do produce some different isotopes that need to be managed. Overall, they're significantly "cleaner" and "safer" than a uranium fuel cycle.

      In either case, using fuel reprocessing, you drastically reduce the nuclear waste. If you do it well, you can separate it into short-lived waste that needs only to be buried for ~400 years, and long-lived waste, which is less of a risk, and could be safely mixed in with the original ore from which the Ur or Th was mined. That ore would be less radioactive than it was before mining. Yes, I did just say that we could dispose of "radioactive waste" by putting it back where we originally mined the Ur/Th, AND that that would leave LESS radiation in the environment than was there naturally.

      That would require people get over the fear of the terms "nuclear" and "radiation" (which we're exposed to constantly), and it would require changes in environmental regulations. I know it sounds scary, to put the waste back into the tailings from which it was mined, but that's actually the safest way to dispose of it, and it has a net effect of reducing radiation in the environment.

    Of-course this is assuming that an activist can be fully converted into energy, but since an average activist is against all forms of energy that people actually need to live, we can also conclude that activists are generally against human survival, and thus they are self-defeating. If the activists get their way, there will be no humans, but there also will be no activists, so by converting activists into energy even in less efficient ways (an open fire stove), would still provide us with some energy and bring the Earth closer to the blissful moment, when the people are removed from it, starting with the activists.

    While nuclear can be done safely, there seems to be no effort to do so - as it would deny environmentalists a chance to remake the power grid in their own way.

    Nuclear isn't done so much in the US because of litigation. The instant somebody announces they're going to be looking at building a nuke plant anywhere, the lawyers come out from the rocks and start burying the courts in paperwork, trying for injunctions to stop any and all nuclear construction.

    Nuclear plants are expensive. They wouldn't be nearly as expensive if it weren't for the legal fees associated with the word 'nuclear'. When you have an activist-lawyer go in front of a camera and say "The only phisics I know is Ex-Lax', you know you're dealing with idiots.

    Just read the history of the Perry Nuclear Plant. Most of the 'construction time', the plant was idle, nothing was moving due to the injunctions. They weren't even allowed to do maintanance on what they already had up, so when the injunctions lifted, they got the construction crews in there to inspect 100% and replace anything that even LOOKED like it had a rust spot, or they wouldn'tve received their operating license. And they had to keep full construction crews on the payroll even while they were waiting for the injunctions to crawl through the courts because if they didn't, the crews would vaporise off to other jobs with no guarantee of getting them back. Half the time they just barely got through with the inspection and maint before they got hit with yet another injunction. The lawyers made tons of money on that project.

    All told, Perry cost $6 billion and took 9 years to build, mostly due to the injunctions. They never did finish the #2 Unit because of cash flow problems from all the litigation. Even though all but the containment vessel is done for #2, they stopped construction on it in '85 & 'abandoned' it in '94. They still have to do maintanance on the empty building in order to keep their license to operate since it's considerted legally to be 'one complex'. It could have gone online with both reactors at half the cost and within 3 years of groundbreaking if it wasn't for all the injunctions.
