摘要:
近期美国核管会NRC颁布的标准审查大纲《Standard Review Plan》Rev.3(2007)版已通过我国核安全审评中心翻译出版，表明我国核安全局将按最严的国际标准执行核工程的安全审查。通过对比美国核管会标准审查大纲SRP 3.7.2节1989版、2007版以及最新2013版的抗震主系统主要内容，结合以往核电工程抗震分析的实践经验，按其所列验收准则各条分别作出专业性的讲解与点评。研究表明：SRP 2013版在概念上更清晰，并在可操作性上更加完善，研究成果对理解核电厂抗震主系统分析要求具有很好的参考价值。 Abstract:Recently, the third revesion of Standard Review Plan for the review of safety analysis reports for nuclear power plants (SRP Rev.3) issued by U. S.A NRC in 2007 has been translated and published by Beijing Review Center of Nuclear Safety, which states clearly National Nuclear Security Administration will carry out the most rigorous international standards in safety review of nuclear projects. In this investigation we studied the different versions of Seismic System Analysis SRP 3.7.2 in 1989, 2007 and 2013, combined with the past practical experiences of nuclear seismic analysis, then concluded the technical explanation and reviews according to the acceptance criteria of each standard clause. The results shown that the 2013 version of SRP was clearer in concept and more perfect in operation. This work provides good guidance for seismic system analysis of NPPs.
