Analysis on the Critical Security and Influence Factors of the Spent Fuel Pool

In this paper the spent fuel in storage grid is assumed to be the new fuel, then the critical security of APIO00 spent fuel storage rack is analyzed and computed.Prelimina- ry validation shows that the parameters of framework can satisfy the criticality safety stand- ards.And the water density in the spent fuel storage pool will be the main influence factors to study the spent fuel storage criticality safety problems.
