Nuclear fuel strategies
-
Disposal of spent nuclear fuel is a major political and public-perception problem for nuclear energy. From a radiological standpoint, the long-lived component of spent nuclear fuel primarily consists of transuranic (TRU) isotopes.

Full recycling of transuranic (TRU) isotopes can in theory lead to a reduction in repository radiotoxicity to reference levels in as little as ~500 years provided reprocessing and fuel fabrication losses are limited. However, over a limited timeframe, the radiotoxicity of the ‘final’ core can dominate over reprocessing losses, leading to a much lower reduction in radiotoxicity compared to that achievable at equilibrium.

The basic strategy of Russian nuclear energy is propagation of a closed fuel cycle on the basis of fast breeder and thermal reactors, as well as the solution of the spent nuclear fuel accumulation and resource problems.

This paper presents potential fuel storage scenarios for two options: the current nuclear power replacement strategy, which will see 16 GWe of new capacity installed by 2030 and a median strategy, intended to ensure implementation of the UK’s carbon reduction target, involving 48 GWe of nuclear capacity installed by 2040.

Partitioning and transmutation strategy R&D for nuclear spent fuel: the SACSESS and GENIORS projects
In this context, and in the continuity of the FP7 EURATOM SACSESS project, GENIORS focuses on the reprocessing of MOX fuel containing minor actinides, taking into account safety issues under normal and mal-operation.

In this paper, is addressed the stability of one of most promising extractants (TODGA, N,N,N0,N0-tetraoctyldiglycolamide) but also the importance of designing realistic model to simulate and study the degradation of the systems.

Another closely-related dynamic is a fundamental shift that is taking place in terms of priority geographic markets. A 2011 global CEO survey by PricewaterhouseCoopers (PWC’s Growth Reimagined) found that the large majority of corporate executives have shifted their primary focus to developing markets. Although doing business in these markets is nothing new, making them the primary target market, where firms plan to invest the majority of their efforts and expect the majority of their future sales, is new and significant.

At the same time, both countries chemically process liquid HLW in order to immobilize it for safer storage and disposal. The United States and Russia, however, have different approaches to and long-term strategies for realizing end points for SNF and HLW. The United States currently plans to transport SNF to a geologic repository for disposal without chemical processing. Russia plans to develop the capacity to chemically p
