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.
