摘要
介绍了华龙一号核电站大气排放系统在系统设计、压缩空气储罐材质变更、大气排放阀消音器结构优化三方面的优化措施。系统设计优化加快了在蒸汽发生器传热管断裂(SGTR)基准事故下一回路的快速冷却,增强了系统的余热导出能力,并为系统提供冗余的超压保护。压缩空气储罐的材质修改解决了采购困难问题,消音器的构造优化避免了调试、运行中的安全隐患。
The optimization measures of the air emission system of HPR1000 Nuclear Power Plant in three aspects:system design,material change of compressed air storage tank,and optimization of the structure of air emission valve silencer are introduced.System design optimization accelerates rapid cooling of the circuit following a steam generator heat transfer tube break(SGTR)reference event,enhances the system's waste heat extraction capability,and provides redundant overpressure protection for the system.The material modification of the compressed air storage tank solves the problem of procurement difficulties,and the optimization of the structure of the silencer avoids potential safety hazards in commissio-ning and operation.
