随着核电厂的运行,由于运行环境、设备性能、警卫力量等变化,会导致电厂实物保护系统的能力发生变化,因此核电厂管理人员能否及时发现系统缺陷或薄弱环节对核电厂重要安全设施和核材料的安全有着重要意义。文章通过对集成安全系统薄弱点分析方法(VISA)的分析介绍,以期核电厂管理者能够通过此方法评估电厂实物保护系统性能,并能够采用有针对性的改进和补救措施改善或增加实物保护系统的能力。
With the operation of nuclear power plants, due to changes in operating environment, equipment performance, security forces and other changes will lead to changes in the ability of plant physical protection system, so NPP managers can detect system defects or weaknesses in time to the nuclear power plant important safety facilities And the safety of nuclear materials is of great significance. The article introduces the analysis of VISA, in order that NPP managers can evaluate the physical protection system performance of power plant by this method and can improve or increase the physical protection system by using the targeted improvement and remedial measures Ability.
