核电厂辐射控制区不同进出模式运行成本分析

Running Cost Analysis for Different Access Modes in Radiation Control Areas of Nuclear Power Plants

本文从核电厂控制区两种进出模式在防护用品的使用量、清洗防护用品的废液产生量以及固废产生量方面对日常运行期间和大修期间进行了运行成本分析。分析可知,采用清洁控制区模式控制区进出模式无论在日常运行期间还是大修期间,其运行成本均低于传统“七件套”模式。尤其是日常运行期间,清洁控制区模式的运行成本仅占“七件套”模式的约三分之一。

We analyze the running costs for operations and outages,with respect to the two access modes in controlled areas of nuclear power plants.The use of protective equipments,the production of liquid waste from cleaning protective equipments and the production of solid waste are all taken into account.The analysis shows that the running cost for the EVEREST mode is lower than that for the traditional"Seven-piece-set"mode,whether during operations or outages.For typical daily operations,the running cost for EVEREST accounts for only about one third of that for"Seven-piece-set"mode.
