[1D12] Development of Fuel Performance Code FEMAXI-8

Model Improvements for Light Water Reactor Fuel Analysis and Systematic Validation

*Yutaka Udagawa1, Masaki Amaya1 (1. Japan Atomic Energy Agency)

Keywords:Fuel Performance Code, LWR Fuel, High Burnup, Fission Gas Release, Relocation

FEMAXI-8 is the latest version of the fuel performance code FEMAXI developed by JAEA. A systematic validation work has been achieved against 144 irradiation test cases, after many efforts have been made, in development of new models, improvements in existing models and the code structure, bug-fixes, construction of irradiation-tests database and other infrastructures.
