台山核电厂气态流出物取样代表性评述

Discussion on Representativeness of Sampling of Airborne Effluents in Taishan NPP

本文介绍了台山核电厂烟囱气态流出物取样监测系统的设计,并结合ISO 2889-2010标准要求,对该系统取样代表性进行了评述,为核电厂烟囱气态流出物取样监测系统的设计和审评提供参考。

Gaseous release is one of the main two ways in which radioactive effluents of nuclear power plants（NPPs） release to the environment in the normal operation.Representativeness of sampling of the effluents should be ensured to accurately determine the discharge quantity of effluents.This paper introduces the design of sampling and monitoring systems of airborne radioactive effluents from the vent in the Taishan NPP,discusses the representativeness of sampling from gaseous effluents in the Taishan NPP taking into consideration of the new requirements of the standard of ISO 2889-2010,presents some advices on design improvements for sampling and monitoring system for the gaseous effluents of the future EPR NPP,which could be a reference for reviewing representativeness of sampling of airborne effluents in NPP.
