摘要: 新燃料贮存主要涉及到的核安全问题是临界安全。对新燃料组件临时存放的方案进行临界安全计算时必须考虑两项独立事件的情况下组件的临界安全。采用SCALE对三门核电将首炉新燃料组件存放于冲洗井中的方案进行了临界计算。计算结果显示,即使在极限的两项独立事件同时发生的前提下, 三门核电首炉机组的燃料组件在冲洗井中存放的临界安全也是有保障的。

Abstract: Criticality safety is a major concern for nuclear safety in new fuel storage. Double contingency accident of new fuel criticality safety analysis must be considered for new fuel storage. SCALE was used for the criticality analysis of new fuel stored in cask washdown pit in Sanmen Nuclear Power Plant in this paper. The results show that plans for new fuel storage in cask washdown pit in Sanmen Nuclear Power Plant are safe even when two independent abnormal events occur simultaneously.

Key words: AP1000 new fuel, cast washdown pit, criticality safety analysis
