摘要
核电站的年度换料大修是整个核电站核安全风险较大的一项重要生产活动。在大修期间,大量核安全相关设备退出,安全保障系统无法正常运行,一旦发生事故,可采用的安全对策较少。为了降低核安全风险,结合核安全控制的反应性控制、堆芯冷却和放射性物质的包容等三大屏障,以及与机组正常相比运行时要更低的运行功率来说,加强大修期间核安全监督管理是非常有必要的。
The annual refueling overhaul of nuclear power plants is an important production activity with a large nuclear safety risk.During the overhaul,a large number of nuclear safety related equipments were taken out of operation,and the safety assurance system could not operate normally.Once an accident occurred,fewer safety measures could be taken.In order to reduce the nuclear safety risk,combined with the three barriers of nuclear safety control reactive control,core cooling and containment of radioactive materials,and the lower operating power compared with the unit,strengthen nuclear safety supervision and management during overhaul.It is very necessary.
