摘要: 某核电厂采用了国际上比较先进的 “EVEREST”进出控制区模式,人员可以穿着普通劳保服进出辐射控制区。为避免或减少辐射控制区内因设备意外泄漏导致的污染扩散和人员沾污,该核电厂控制区采用潜在污染风险管理方式,包括通过分析反应堆回路主要设备的放射性介质包容可靠性以及已发生的污染事件原因,识别潜在污染区域,对控制区进行污染分区,并对潜在污染区和实际污染区设置边界,对进入的人员进行相应的防护。

关键词: 表面污染, 潜在表面污染, EVEREST, 核电厂

Abstract: A nuclear power plant adopts the international advanced “EVEREST” access controlled area mode, which allows personnel enter and leave the radiation controlled area in ordinary labor protection clothing. In order to avoid or reduce contamination spread and human contamination caused by accidental leakage of equipment in the radiation controlled area, the potential contamination risk management method were adopt in the controlled area of the nuclear power plant, which includes analyzing the reliability of the radioactive media inclusion of the main equipment in the nuclear loops and the causes of the contamination events that have occurred, identifying the potential contamination area, dividing the controlled area and setting boundaries for potential contamination area and the actual contamination area, and providing the personal protection accordingly.

Key words: surface contamination, potential surface contamination, EVEREST, nuclear power plant
