摘要
潜在通路分析是一种常用于提高电路设计可靠性的方法。给予功能延伸,将潜在通路分析(S C A)技术引入AP1000核电厂主回路系统的设计分析。通过建立和主回路工艺特性相适应的模型,并采用人工路径搜索技术,判明标准设计中存在潜通路,再通过分析提出了工程上较为可行的方案,算例表明该方案可明显降低潜通路的影响。
Sneak circuit analysis is a papular method for circuit reliability design. By extending the methodology, sneak circuit analysis is applied in the design of RCS of AP1000 nuclear power plant based on the modeling of process system properly. With the manual path searching technique, the sneak paths are disclosed in the current standard design. Based on further analysis, a practical engineering proposal is given and the simulation indicates the effectiveness of decreasing the effects of sneak paths.
