摘要
Abstract
AP1000 passive power plant uses passive water supply to provide cooling for the spent fuel pool after the accident,and the critical safety analysis requires that the boron concentration in the spent pool is higher than the minimum allowable boron concentration to ensure sufficient subcritical margin.Based on the design of AP1000 spent fuel pool,using CFD fluid analysis software,porous media model and component transport model are used to simulate the effect of non-boronized water supply on non-uniform boron dilution in fuel storage area.The results show that the local boron concentration in the fuel storage area is reduced by the dilution of non-boronized water sources.Under the premise of effective control of water replenishment,the local boron concentration is reduced to about 2 140 ppm,which is higher than the allowable minimum boron concentration,thereby does not affect the critical safety of spent fuel.关键词
