AbstractAbstract
[en] Conceptual design of DUPIC irradiation pellets with double cladding was carried out. And the preliminary study of the temperature effect on the design and manufacturing parameters of DUPIC pellets through HEATING and GENGTC was performed. The analysed results of the newly designed DUPIC pellets to be irradiated in HANARO, were, 1) thermal conductivity of fuel, linear power of fuel and axial gap affected greatly the temperature of fuel, 2) thickness of sheath, gamma heating rate and thermal transfer coefficient affected little the temperature of fuel. 3) the centerline temperature calculated by HEATING was evaluated higher than that by GENGTC such presented to be desirable for using GENGTC in the view point of safety GENGTC, 4) by transient thermal analysis, after 160 seconds, the temperature of fuel reaches its equivalent temperature.
