摘要: 梳理了核电厂控制区人员进出管理的要求,介绍了CPR1000压水堆核电厂控制区人员进出的流程及国际上控制区人员进出管理的先进模式——“珠峰”模式。CPR1000压水堆核电厂控制区人员进出管理以辐射分区为基础,进入控制区时需要先将自身衣物脱掉,再更换辐射防护衣物,控制区进出流程复杂。“珠峰”模式是指一种无需更换衣服直接进入核电厂控制区的人员进出管理方式,以污染分区概念为基础,对核电厂控制区内进行细致的污染分区,针对各污染分区制定不同的防护用品使用规则和进出流程,从而简化核电厂控制区人员进出流程。文章最后从进出控制区的时间、污染物水平、工器具管理、人员意识等几方面对两种人员进出控制区的优缺点进行了对比分析,并指出EVEREST是压水堆核电厂控制区人员进出管理发展的方向,能够适用于现役核电厂的改造。

Abstract: The paper reviews the access requirements of radioactive control area in NPP, and introduces the access process of CPR1000 as well as the international advanced access control mode “EVEREST”. The access management of radioactive control area for CPR1000 NPPs based on radiation zoning requires outer-layer clothes off first and then radiation protective clothing on before entering into the control area, which is complicated comparing with the “EVEREST” mode, which bases on contamination zoning and evolves towards an entrance without universal dress. “EVEREST” needs exact contamination partition, and adopts different radiation wear and access process for each zone. Its purpose is to simplify the NPP radioactive control area access. By comparison, EVEREST is found a good applicability for the recast of in-service PWR NPPs.

Key words: pressurized water nuclear power plant, radioactive control area, people access, “EVEREST” mode
