Spent Nuclear Fuel Transport: Problem State and Analysis of Modern Approaches

Cost analysis of the US spent nuclear fuel reprocessing facility

a r t i c l e i n f o The US Department of Energy is actively seeking ways in which to delay or obviate the need for additional nuclear waste repositories beyond Yucca Mountain. All of the realistic approaches require the reprocessing of spent nuclear fuel. However, the US currently lacks the infrastructure to do this and the costs of building and operating the required facilities are poorly es...

Investigation of the required thickness of thorium spent fuel lead transport cask depending on different fuel burnups and cooling times

Thorium fuels have attracted researcher’s attention due to the reduction of uranium deposits in the world, more abundances than uranium, and the ability to be breeding in thermal and fast reactors. This study aimed to investigate the radiation safety and the amount of necessary shielding for the transportation of spent thorium fuel in the Tehran Research Reactor. The ORIGEN and MCNPX computatio...

Partitioning and Transmutation of Spent Nuclear Fuel by Peacer

Challenges of managing long-living spent nuclear fuel wastes are to be technically overcome by a partitioning and transmutation system named as PEACER that is an abbreviation of its design goals: Proliferation-resistant, Environment-friendly, Accident-tolerant, Continuable and Economical Reactor. PEACER has been developed to manage spent nuclear fuels by uniquely combining Pb-Bi cooled critical...

Modal Analysis of Spent Fuel Cask for WWER-1000 Reactors

The Spent Fuel Assemblies (SFAs) of WWER-1000 reactors are planned to be transported by special containers which are supposed to be designed in a manner to stand against vibrations and impacts in order to protect the spent fuel from any possible damage. The vibration opposition of these containers shall be far beyond the critical resonance, because the resonances about the natural frequency of ...
