秦山核电站燃料元件考验回路是为了考验秦山核电站燃料元件而设计的,它安装在重水研究堆上。运用概率安全评价方法(PSA)对考验回路进行分析,其目的是为了估价它的安全性和评价此回路的设计。分析的步骤和模式与核电站的PSA相同。主要步骤是熟悉此系统,调查和选择初因事件,建立事件树、故障树,收集数据,定性分析、定量分析和结果分析。分析仅限制在考验回路的初因及正常运行时考验回路操纵员可能的失误。分析结果:事故发生的总频率小于10~(-4)a(-1),此事故发生频率作为考验回路安全运行是可以接受的。对考验回路的设计提出改进意见,特别是关于操纵员的人因失误。
Qinshan nuclear power plant fuel components test circuit is designed to test the Qinshan nuclear power plant fuel components designed, it is installed in heavy water research reactor. The probabilistic safety assessment method (PSA) is used to analyze the test circuit in order to evaluate its safety and to evaluate the design of this circuit. The steps and modes of analysis are the same as those of a nuclear power station. The main steps are to familiarize yourself with the system, investigate and select incidents, establish event trees, fault trees, collect data, qualitative analysis, quantitative analysis, and analysis of results. The analysis only limits the initial cause of the test circuit and tests the possible errors of the circuit operator during normal operation. Analysis results: The total frequency of accidents is less than 10 ~ (-4) a (-1). The frequency of this accident is acceptable as the test circuit safe operation. Comment on the design of the test circuit to improve, especially on the human error of the operator.
