Fuel performance modeling of transuranic burning boiling water reactor

Description
Reduced-moderation boiling water reactor could serve as near-term alternative to sodium fast reactors for the application of transuranic waste incineration. To accurately analyze the fuel rod behavior of this reactor, modification of existing LWR fuel performance code is necessary because of significant deviation from typical operating condition of light water reactors. In this work, physical phenomena relevant to high temperature and high burnup conditions previously modeled and implemented in FRAPCON-EP have been upgraded to FRAPCON-3.5. Semi-empirical models describing porosity and cesium migration behaviors have been replaced with mechanistic models. Hydrogen migration and precipitation kinetics in cladding have been added in the new version of FRAPCON-EP. Fuel performance comparison between RBWR-TB2 and ABWR fuel rods has performed. The results suggest that because of high axial peaking factors and relatively flat power history combined with high peak burnup, fuel temperature is significantly higher in fissile zones of RBWR-TB2 leading to various undesirable effects such as excessive corrosion and cladding deformation.
