Sensitivity analysis of nuclear fuel cycle transitions
The present United States nuclear fuel cycle faces challenges that hinder the expansion of nuclear energy technology. The U.S. Department of Energy identified four classes of nuclear fuel cycle options the U.S could transition to, which would overcome these challenges and make nuclear energy …

Rethinking the light water reactor fuel cycle
The once through nuclear fuel cycle adopted by the majority of countries with operating commercial power reactors imposes a number of concerns. The radioactive waste created in the once through nuclear fuel cycle has to be isolated from the environment for thousands of years. In addition, plutonium …

Modeling special nuclear material diversion from a pyroprocessing facility
As a result of the once-through fuel cycle implemented in the US, used nuclear fuel (UNF) steadily increases. One proposed solution is the transition to a closed nuclear fuel cycle, in which reprocessing reduces build up of UNF. Pyroprocessing is an attractive method for this transition for its …

Development of thermodynamic cycles for sodium-cooled-fast reactors.
… an interest to design reactors that operate on a closed fuel cycle, and SFR is one of the potential options. A BN-600 reactor is a sodium-cooled fast-breeder reactor built at the Beloyarsk NPP in Russia, and it is in operation since 1980. On the secondary side it utilizes a subcritical-pressure …

An evaluation of the net breeding capability of heterogeneously-fuelled pressure-tube heavy water reactors with the thorium fuel cycle
The thorium fuel cycle is a promising future option for an alternative to uranium. The pressure tube heavy water reactor (PT-HWR) has for decades been considered capable of achieving net breeding on the thorium fuel cycle, but this capability has not been conclusively demonstrated. The goal of this …
