【摘要】：绝大多数核电厂概率风险评价均以单个反应堆为单位,安全目标的制定也是如此。事实上,同一场址(site)上有多座核电厂(plant)、同一厂址(plant)上有多个反应堆(reactor)的情况并不罕见。为将概率风险评价从单个反应堆推广至整个场址,本文在定义场址风险的基础上,针对始发事件展开分析,给出其分类及识别方法建议。分析表明,多堆场址的始发事件可归入2类单堆始发事件,以及3类多堆始发事件。此结果是开展多堆场址概率风险评价的第1步,具有重要价值。
[Abstract]:Most probabilistic risk assessments of nuclear power plants are based on individual reactors, as are safety objectives. In fact, it is not uncommon for (site) to have multiple nuclear power plants on the same site, (plant), on the same site, and multiple reactors on (plant) on the same site. In order to extend the probabilistic risk assessment from a single reactor to the whole site, this paper defines the site risk, analyzes the origin events, and gives some suggestions for classification and identification. The analysis shows that the initiation events of multi-heap sites can be classified into two types of single-heap events and three types of multi-heap events. The results are the first step in the probabilistic risk assessment of multi-reactor sites and are of great value.
