摘　　要：核电厂厂用电系统的功能是为核电厂设施提供安全可靠的电源,核电厂供电安全对核安全至关重要。福岛第一核电厂就是在丧失厂用电及最终热阱的情况下发生了严重的核事故。厂用电系统具备两列相互独立的厂外电源作为工作电源和辅助电源。文章通过收集国内外运行核电厂丧失厂外电事件,对运行核电厂丧失厂外电的机组状态、事件发生原因进行了分析,提出了应对厂外电失效的改进措施和建议。The function of the service power system of a nuclear power plant is to provide safe and reliable power supply for the nuclear power plant facilities. The safety of nuclear power plant power supply is essential for nuclear safety. The serious accident of Fukushima Dail＇chi nuclear power plant occurred due to loss of service power and the ultimate heat sink. The service power system has two independent offsite power supplies as working power and auxiliary power. This article collected events of loss of offsite power supply in operating nuclear power plants at home and abroad, and analyzed the plant status and cause of loss of offsite power supply events, and proposed improvement measures for dealing with loss of offsite power supply.
