ABSTRACT

During 2005 CNEA has continued and developed new RERTR activities. Main goals are the plan to convert our RA-6 reactor from HEU to a new LEU core, to get a comprehensive understanding of U-Mo/Al compounds phase formation in dispersed and monolithic fuels, to develop possible solutions to VHD dispersed and monolithic fuels technical problems, to optimize techniques to recover U from silicide scrap samples as cold test for radiowaste separation for final conditioning of silicide spent fuels and to improve the diffusion of LEU target and radiochemical technology for radioisotope production.
Future plans include

• Completion during 2006 the RA-6 reactor conversion to LEU
• Improvement on fuel development and production facilities to implement new technologies, including NDT techniques to assess bonding quality.
• Irradiation of miniplates and full scale fuel assembly at RA-3 and plans to perform irradiation on higher power and temperature reglme reactors
• Optimization of LEU target and radiochemical techniques for radioisotope production.
