[3H14] Introduction of MOX and Pu-ROX fuels in PBR with accumulative fuel loading scheme
Keywords:Pebble bed reactor, Accumulative fuel loading scheme, MOX fuel, Pu-ROX fuel, High burnup performance
MOX and Pu-ROX fuels were introduced in PBR with accumulative fuel loading scheme. The purpose was to obtain high burnup with long operation time. MVP-BURN was used for burnup calculation. The results showed that maximum discharge burnup and operation time of Pu-ROX fuel was higher than that of MOX fuel. Moreover, negative temperature coefficient for both fuels were reached in all temperature conditions.
