Design of test fuel rod for high burnup UO2 pellets in HANARO irradiation capsule

Creators

Description

Test fuel rod was designed to irradiate the large grain UO2 pellet developed for the high burnup LWR fuel in the HANARO in-pile capsule. UO2 pellets will be irradiated up to the burnup higher than 70 MWD/kgU. To irradiate the UO2 pellets at the power and temperature conditions equivalent to LWR fuel, in-pile behavior of test rods was analyzed by varying the fuel rod filling gases. In addition, to satisfy the safety criteria of HANARO such as prevention of ONB(Onset of Nucleate Boiling), fuel melting and wear damage of the capsule during the long term irradiation, design of coolant flow channel and flow rate in the capsule was optimized
