摘　　要：本文分析了HFETR概率安全分析所需的设备基本信息,针对部分设备采集或记录数据较少、难以通过经典估计方法得到准确的可靠性参数的情况,本文采用通用数据源和贝叶斯估计方法应用信息化管理技术,设计和开发了HFETR设备可靠性数据库管理系统,并借鉴核电厂的数据,验证了该系统估算的设备可靠性参数的准确性,为HFETR一级PSA、在线风险评价及以可靠性为中心的维修奠定了基础。This paper analyzes the basic information of equipment required for HFETR probabilistic safety analysis. For some of the equipment, it is difficult to get accurate reliability parameters through the classical estimation method due to the small amount of data collected or recorded. General data source and Bays estimation method are adopted. By applying information management technology, the reliability database management systems of HFETR equipment is designed and developed, and the accurate of the reliability parameter estimation results of the system is verified by referring to the data of nuclear power plant, which lays a foundation for providing basic reliability data for HFETR level 1 PSA, online risk assessment and reliability-centered maintenance.
