田湾核电站长周期换料冷却剂流量丧失事故分析

Loss of Flow Accident Analysis on Long Fuel Cycle for Tianwan Nuclear Power Station

摘要: 田湾核电站采用长周期燃料循环策略后，堆芯热工物理参数发生变化，最终安全分析报告的结论已不适用，需要对事故工况进行重新分析。本文给出了失流事故分析的主要假设和分析方法，采用瞬态计算程序DINAMIKA-97计算分析了失流事故。分析结果表明，所有失流事故均满足安全准则的要求，核电站的安全是能够保障的。

Abstract: After the long fuel cycle is adopted at Tianwan Nuclear Power Station (TNPS), the core thermal and physical parameters will be changed, thus the conclusion in Final Safety Analysis Report is not applicable, and therefore the accidents need to be reanalyzed. In this paper the main assumptions and analytical methods were presented, and the transient calculation program of DINAMIKA-97 was used in analyzing the loss of flow accident. The analysis results indicate that all the safety criteria are met for the loss of flow accident, and the nuclear power station safety can be ensured.
