There is constant debate about whether conventional reprocessing and recycling that is, the closed fuel cycle should be commercially deployed, given the sensitive processes inherent in these aspects of the fuel cycle. As technologies become more widely available, the debate increasingly circulates around which states are already incorporating these aspects of the fuel cycle, which states intend to do so, and whether these policies pose problems for the international community. Numerous reports have compared conventional reprocessing technologies, but as each one points out, it is tremendously difficult to create a uniform system of analysis or baseline for comparison.

Nuclear reprocessing

To compete and thrive in the 21st century, democracies, and the United States in particular, must develop new national security and economic strategies that address the geopolitics of information. In this century, democracies must better account for information geopolitics across all dimensions of domestic policy and national strategy. This process has to be examined in the context of the current strategic competition between China and the U.

For decades, there has been an intense debate over the best approach to managing spent fuel from nuclear power reactors, whether it is better to dispose of it directly in geologic repositories, or reprocess it to recover and recycle the plutonium and uranium, disposing only of the wastes from reprocessing and recycling. The relative costs of reprocessing vs.

Economics is not the only or even the principal factor affecting decisions concerning reprocessing today. But economics is not unimportant, particularly in a nuclear industry facing an increasingly competitive environment.

At a minimum, if reprocessing is being done to achieve objectives other than economic ones, it is worthwhile to know how much one is paying to achieve those other objectives. While some analysts have argued in recent years that the costs of reprocessing and direct disposal are similar, and that reprocessing will soon be the more cost-effective approach as uranium prices increase, the data and analyses presented in this report demonstrate that the margin between the cost of reprocessing and recycling and that of direct disposal is wide, and is likely to persist for many decades to come.

In particular:. Since the total back-end cost for the direct disposal is in the range of 1. Even though most new reactors are built with storage capacity for their lifetime fuel generation, so few additional costs for interim storage need be incurred. Therefore the extra electricity cost, were these approaches to be pursued, would be even higher. Arguments for separations and transmutation to limit the need for additional repositories rest on a number of critical assumptions that may or may not be borne out in practice.

In this report, we have focused only on the economic issues, and have not examined other issues in the broader debate over reprocessing. Nevertheless, given a the costs outlined above; b the significant proliferation concerns that have been raised particularly with respect to those reprocessing approaches that result in fully separated plutonium suitable for use in nuclear explosives ; and c the availability of safe, proven, low-cost dry cask storage technology that will allow spent fuel to be stored for many decades, the burden of proof clearly rests on those in favor of investing in reprocessing in the near term.

A key, nearly unique, characteristic of nuclear energy is that used fuel may be reprocessed to recover fissile and fertile materials in order to provide fresh fuel for existing and future nuclear power plants. Several European countries, Russia, China and Japan have policies to reprocess used nuclear fuel, although government policies in many other countries have not yet come round to seeing used fuel as a resource rather than a waste. This contributes to national energy security. A secondary reason is to reduce the volume of material to be disposed of as high-level waste to about one-fifth. In addition, the level of radioactivity in the waste from reprocessing is much smaller and after about years falls much more rapidly than in used fuel itself. Uranium mining will become much less significant.

Transmutation of transuranics TRUs and fission products that are recovered from spent fuel offers potential for improving the technology for long-term disposal of radioactive waste. This appendix addresses various economic issues related to the use of transmutation as a primary waste management strategy, focusing primarily on future reprocessing costs under various plant ownership and financing arrangements. It also addresses the substantial institutional barriers that would inhibit private-sector financing of such a strategy in the United States. The nuclear industry of the early s was characterized by rapidly increasing worldwide demand for generating commercial nuclear power capacity, rising uranium prices, and an impending shortage of uranium enrichment capacity. There was a consensus within the nuclear community that spent reactor fuel would be reprocessed to recover residual uranium and plutonium for recycle in light-water reactors LWRs and ultimately to fuel breeder reactors.

Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. With commercialization of nuclear power , the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors. It can employ all the actinides , closing the nuclear fuel cycle and potentially multiplying the energy extracted from natural uranium by about 60 times.

Ultimately, most critical decisions have been made by the leadership of the Chinese state and the Communist Party of China. China committed to generating electricity using nuclear fission energy with two significant steps.

Reprocessing and Recycling of Spent Nuclear Fuel presents an authoritative overview of spent fuel reprocessing, considering future prospects for advanced closed fuel cycles. Part One introduces the recycling and reprocessing of spent nuclear fuel, reviewing past and current technologies, the possible implications of Generation IV nuclear reactors, and associated safely and security issues. Parts Two and Three focus on aqueous-based reprocessing methods and pyrochemical methods, while final chapters consider the cross-cutting aspects of engineering and process chemistry and the potential for implementation of advanced closed fuel cycles in different parts of the world.

Recycling versus Long-Term Storage of Nuclear Fuel: Economic Factors

The objective of the present study is to compare the associated costs of long-term storage of spent nuclear fuel—open cycle strategy—with the associated cost of reprocessing and recycling strategy of spent fuel—closed cycle strategy—based on the current international studies. The analysis presents cost trends for both strategies. Also, to point out the fact that the total cost of spent nuclear fuel management open cycle is impossible to establish at present, while the related costs of the closed cycle are stable and known, averting uncertainties.

Сьюзан отказывалась что-либо понимать. Она была абсолютно уверена, что не вводила такой команды - во всяком случае, намеренно. Подумала, что, может быть, спутала последовательность нажатия клавиш. Немыслимо, - подумала. Согласно информации, появившейся в окне, команда была подана менее двадцати минут. Сьюзан помнила, что за последние двадцать минут вводила только свой персональный код, когда выходила переговорить со Стратмором.

Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола. Хотя Стратмор терпеть не мог выделять кого-нибудь из подчиненных, он с особым вниманием относился к своей единственной сотруднице. Когда его обвиняли в фаворитизме, он в ответ говорил чистую правду: Сьюзан Флетчер - один из самых способных новых сотрудников, которых он принял на работу. Это заявление не оставляло места обвинениям в сексуальном домогательстве, однако как-то один из старших криптографов по глупости решил проверить справедливость слов шефа. Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств. На фотографии она была изображена наклонившейся над постелью, в одних трусиках.
