Description
Post-irradiation examination on 'JOYO' MK-II core fuel subassemblies and fuel irradiation behavior analysis have been conducted in Fuels and Materials Division. It was confirmed through these examinations that they performed satisfactorily during 'JOYO' operation and no failure was occurred. Fuel behavior dependency on burnup, linear heat rate etc. was made clear by plenty of data. Fuel behavior such as fuel temperature, material strength, FP gas release rate, FCCI, fuel pin diameter change etc. were conservative than those of estimated by design, which demonstrated the adequacy of fuel design for 'JOYO' MK-II. The fuel life at the end of using still have enough margin compared with life limit evaluated from actual irradiation data and the possibility of fuel design method improvements was suggested.
