Nuclear fuel in a reactor accident.

Nuclear accidents that lead to melting of a reactor core create heterogeneous materials containing hundreds of radionuclides, many with short half-lives. The long-lived fission products and transuranium elements within damaged fuel remain a concern for millennia. Currently, accurate fundamental models for the prediction of release rates of radionuclides from fuel, especially in contact with wat...

Fast Reactor Fuel Reprocessing Technology in India

The limited indigenous uranium resource coupled with the need of energy independence necessitated the Department of Atomic Energy (DAE) in India to opt for a three-stage nuclear power program comprising of PHWRs in Stage 1, FBRs in Stage 2 and Th-U based reactors in Stage 3, respectively to meet the energy needs of the growing Indian economy. Presently the country has stepped into the 2nd Stage...

Monolithic Fuel and High-Flux Reactor Conversion

Monolithic fuels are the most promising candidate for a next generation of high-density research reactor fuels. If successfully developed, the remaining HEU-fueled reactors in the world could presumably be converted to low-enriched fuel — and the use of highly enriched uranium in the civilian nuclear fuel cycle eventually terminated. The most challenging type of reactors to convert are single e...
