The separation of /sup /U and /sup /U in the reprocessing of HTGR fuels is a key feature of the feed-breed fuel cycle concept. This is attained in the Fort St. Vrain (FSV) reactor by coating the fissile (Th-/sup /U) particles and the fertile (Th-/sup /U) particles separately with silicon carbide (SiC) layers to contain the fission products and to protect the kernels from burning in. In India, reprocessing of aluminum-clad thorium fuel has been carried out on fuel irradiated in the CIRUS reactor. The reprocessing of these rods, which had been irradiated to a level up to kg of U per ton of thorium, and cooled for more than two years, was made in a pilot-scale test facility at BARC and at the IGCAR (Anantharaman et Cited by: 1.

reprocessing and refabrication of fuel. The protactinium formed in thorium fuel cycle also cause some problems, which need to be suitably resolved. The information on thorium and thorium fuel cycles has been well covered in the IAEA-TECDOC (May ) File Size: 1MB. The principal gaseous wastes in reprocessing of fuel elements from high-temperature gas-cooled reactors (HTR's) arise from the burning head-end step, from the fuel dissolution operation, from the. In the HTGR fuel particles (UC 2 or ThO,), 10 Ci of '~C/ GW(e)-ir will be formed from 25 ppm of nitrogen. whereas "0 in the ThO, will contribute an additional 2 Cli GW(e)-yr. All I~C contained in the fuels may be released in a gas mixture (CO,. CO. CH~, etc.) during fuel . Nuclear fuel is material used in nuclear power stations to produce heat to power is created when nuclear fuel undergoes nuclear fission.. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear three most relevant fissile isotopes are uranium, uranium and plutonium

This book presents the state of the art on thermophysical and thermochemical properties, fabrication methodologies, irradiation behaviours, fuel reprocessing procedures, and aspects of waste management for oxide fuels in general and for thoria-based fuels in particular.

The sustainability of nuclear energy involves.
