“New” Nuclear Reactors, Same Old Story

“New” Nuclear Reactors, Same Old Story Peak Energy 16 June 09 AMory Lovins has a look at various new forms of nuclear power being touted as the next big thing – “…………

…………on closer examination, the two kinds most often promoted—Integral Fast Reactors (IFRs) and thorium reactors4—reveal no economic, environmental, or security rationale,…………………………
Integrated Fast Reactors (IFRs) – ……………Fast reactors were first offered as a way to make more plutonium to augment and ultimately replace scarce uranium. Now that uranium and enrichment are known to get cheaper while reprocessing, cleanup, and nonproliferation get costlier—destroying the economic rationale—IFRs have been rebranded as a way to destroy the plutonium (and similar transuranic elements) in long-lived radioactive waste. Two or three redesigned IFRs could in principle fission the plutonium produced by each four LWRs without making more net plutonium. However, most LWRs will have retired before even one commercial-size IFR could be built; LWRs won’t be replaced with more LWRs because they’re grossly uncompetitive; and IFRs with their fuel cycle would cost even more and probably be less reliable………………………..
Thorium reactors………………..thorium can’t fuel a reactor by itself: rather, a uranium- or plutoniumfueled reactor can convert thorium-232 into fissionable (and plutonium-like, highly bomb-usable) uranium-233. Thorium’s proliferation,9 waste, safety, and cost problems differ only in detail from uranium’s…………
any new type of reactor would probably cost even more than today’s models: even if the nuclear part of a new plant were free, the rest—two-thirds of its capital cost—would still be grossly uncompetitive with any efficiency and most renewables, sending out a kilowatt-hour for ~9–13¢/kWh instead of new LWRs’ ~12–18+¢. In contrast, the average U.S. windfarm completed in 2007 sold its power (net of a 1¢/ kWh subsidy that’s a small fraction of nuclear subsidies) for 4.5¢/kWh. Add ~0.4¢ to make it dispatchable whether the wind is blowing or not and you get under a nickel delivered to the grid.

Most other renewables also beat new thermal power plants too, cogeneration is often comparable or cheaper, and efficiency is cheaper than just running any nuclear- or fossil-fueled plant. Obviously these options would also easily beat proposed fusion reactors that are sometimes claimed to be comparable to today’s fission reactors in size and cost……………………….
Small reactors……………………….the whole nuclear business will complete its slow death of an incurable attack of market forces. Meanwhile, the rest of us shouldn’t be distracted from getting on with the winning investments that make sense, make money, and really do solve the energy, climate, and proliferation problems, led by business for profit.
