摘要
近年来,国内核电厂发生多起由于海水生物的入侵,导致核电厂机组失去最终热阱而被迫停机停堆。位于杭州湾畔的秦山核电基地也曾发生过类似因海草入侵等,导致机组被迫降功率的事件。对于核电厂来说,反应堆热量的导出是核安全三要素之一,应时时刻刻得到保障,因此,研究核电厂热阱丧失后的运行控制手段显得尤为重要。文章只着重分析了秦山基地M310机组在热阱丧失事件发生时,对机组安全的影响分析,并根据内陆电厂经验提出现有热阱优化方案,改善事故后果的缓解手段。
In recent years,many nuclear power plants in China have been forced to shut down because of the loss of the final heat sink due to the invasion of seawater organisms.Qinshan Nuclear Power Bbase located on the Bank of Hangzhou Bay also experienced similar incidents that the unit was forced to cut power due to seaweed invasion.As one of the three elements of nuclear safety,the export of reactor heat should be guaranteed all the time for nuclear power plants.Therefore,it is particularly important to study the operation control means after the loss of heat sink in nuclear power plants.This paper only focuses on the analysis of the impact on unit safety of M310 unit in Qinshan Base when the loss of heat sink occurs,and according to the experience of inland power plants,it puts forward the optimization scheme of existing heat sink to improve the accident mitigation means.
