摘要
面向开展研究堆概率安全分析(PSA)的需求,以研究堆通用可靠性数据库IAEA-TECDOC-930为通用数据源,基于贝叶斯方法建立了研究堆可靠性数据收集与处理方法,并以西安脉冲堆(XAPR)为对象设计开发了研究堆可靠性数据管理与分析系统,通过该系统的应用获取了不确定性较小且能反映本堆特征的部件可靠性参数。
To carry out the probability safety analysis (PSA) for research reactors, an approach based on Bayesian theory for reliability data collection and processing of research reactors was proposed utilizing the generic reliability data for research reactors from IAEA-TECDOC-930. Moreover, a reliability data management and analysis system for Xi' an Pulsed Reactor (XAPR) was developed. Taking advantage of the system, the reliability parameters suited XAPR feature was obtained.
