通过调研国内外相关资料,并结合国内开展评估工作的经验,分别总结出适用于我国已运行核电站和处于设计阶段核设施的实物保护系统(PPS)有效性评估方法,有助于加强和改进我国核设施的防护措施,提高实物保护系统的有效性和效费比,推进评估工作的规范化。评估方法均基于设施的设计基准威胁,评估过程主要包括调研分析、建立模型和参数设置、薄弱路径分析、情景分析、风险分析、升级改进方案对比分析等内容。对已运行核电站的评估方法还
By investigating the relevant data both at home and abroad and combining with the experience of domestic assessment work, this paper summarizes the evaluation methods of the physical protection system (PPS) applicable to the nuclear power plants that are already in operation in our country and the nuclear facilities in the design stage, which are helpful to strengthen and improve our country Nuclear facilities protection measures to improve the effectiveness of the physical protection system and cost-effectiveness, and promote the standardization of assessment. The assessment methods are all based on the design baseline threat of the facility. The assessment process mainly includes investigation and analysis, model establishment and parameter setting, weak path analysis, scenario analysis, risk analysis, comparison and analysis of upgrade and improvement schemes. The method of evaluation of already operating nuclear power plants also
