福岛核事故发生后,多机组核电厂的总体风险受到越来越多的关注,但国内外缺乏评价多机组核电厂总体风险的方法或导则。本文结合有关法规对核电厂的总体安全要求,探索将单机组的一级概率安全评价(PSA )方法拓展为多机组的风险评价方法。以双机组核电厂为例,讨论了多机组厂址 PSA定量化的一些问题,提出了机组间相关性的一些见解,并阐明了数学原理。本文讨论的方法对研究多机组厂址PS A方法具有重要价值。
福島覈事故髮生後,多機組覈電廠的總體風險受到越來越多的關註,但國內外缺乏評價多機組覈電廠總體風險的方法或導則。本文結閤有關法規對覈電廠的總體安全要求,探索將單機組的一級概率安全評價(PSA )方法拓展為多機組的風險評價方法。以雙機組覈電廠為例,討論瞭多機組廠阯 PSA定量化的一些問題,提齣瞭機組間相關性的一些見解,併闡明瞭數學原理。本文討論的方法對研究多機組廠阯PS A方法具有重要價值。

After the Fukushima nuclear accident ,more and more attentions were paid to the integrated risk of multi-unit nuclear power plant (NPP) ,while there is no any methodology or guideline ,at home or abroad on assessing the integrated risk of multi-unit NPP sites . According to the general requirements for NPP sites by relevant regulations ,an exploration was developed to assess the integrated risk of the multi-unit site by extending the methodology of level-1 probabilistic safety assessment (PSA ) of the single-unit site .A two-unit site was employed as a demonstration to discuss some quantification issues of multi-unit sites ,with some insights on dependencies among the units and mathematical mechanisms . T he approach discussed in this paper is of important value for the research on PSA methods of multi-unit NPPs .
