概要 （英文）

EIMUS,A COMPUTER CODE FOR EVALUATION OF INTEGRATED LWR FUEL PERFORMANCE BY MECHANISTIC MODELLING OF UNSTEADY PROCESSES,IS DEVELOPED. THE CODE IS BASICALLY A MODIFICATION OF FEMAXI-3,IMPLEMENTING A NEW FISSION GAS RELEASE MODEL,FGRBEM,FOR HIGH BURNUP FUELS UP TO 60MWD/KGU. THE MATHEMATICAL MODELS IN EIMUS,WHICH ARE BASED ON BOUNDARY ELEMENT METHOD,CAN ANALYSE DETAILED PROCESSES SUCH AS FISSION GASDIFFUSION IN PELLETS,INTERMIXING OF FISSION GAS AND FILLED HELIUM. DATA FROM BATTELLE HIGH BURNUP EFFECTS PROGRAM AND SOME OTHER INTERNATIONAL PROJECTS ARE UTILIZED FOR CODE VERIFICATIONS.
