Feasibility study on use of LEU [low enriched uranium] and MEU [medium enriched uranium] aluminide fuels in the KUR
- 1. Kyoto Univ., Kumatori, Osaka (Japan). Research Reactor Inst.
Description
Because of the delay of the safety review to use LEU silicide fuel in the KUR, the feasibility study on use of LEU and MEU aluminide fuels (2.2 gU/cm3) was performed. Thermal hydraulic study did not find any difficulty, however, neutronics study has some problems even when beryllium reflector is used instead of the existing graphite reflector. Namely, even when the LEU aluminide fuel is fully loaded in a whole fuel region, a goal depletion of 35 %U-235 can not be attained. On the other hand, the MEU aluminide fuel can get an upgraded performance. It is concluded that for continuation of the KUR operation, either one of the following fuels is needed: 1) the present HEU alloy fuel (0.5845 gU/cm3), 2) MEU aluminide fuel (<2.2 gU/cm3), or (3) LEU silicide fuel (3.2 gU/cm3).
