Abstract
A conceptual design study was carried out on a super high-burnup mixed-oxide (MOX) fuel assembly(SHB FA) for pressurized water reactors (PWRs) using transuranium (TRU). This study aims to avoid the surplus plutonium (Pu) accumulation and to reduce the accumulation of long-lived radioactive minor actinides (MAs) by utilizing the currently existing PWRs under the condition that the Japanese program to develop fast breeder reactors (FBRs) is tend to delay. For this purpose, an SHB FA with discharged burnup of -80GWd/t was investigated by utilizing MAs positively as both burnable absorbers and fissile suppliers and loading high-content Pu. It is possible to load the SHB FAs in a current PWR together with UO2 FAs and to use 2.5 times as much amount of Pu as that in a standard 1/3 MOX core. Moreover, it is found to be possible to reduce the total number of fresh FAs further from that of a high-burnup (55GWd/t in maximum)UO2 (4.9wt%) core and also to reduce the accumulation of MAs in the nuclear fuel cycle significantly.
