关于某核电站厂址废物处理设施液态流出物在线监测报警阈值设定的探讨

Abstract

Abstract: The upper limit of total emission concentration of radionuclides other than ³H and ¹⁴C in a coastal nuclear power plant is 1 000 Bq/L, per Technical requirements for discharge of radioactive liquid effluents from nuclear power plants (GB 14587-2011). In order toeffectively prevent and control of abnormal discharge, it requires that the threshold of on-line monitoring instrument interlock alarm should not exceed the emission concentration control value by a factor of 5. The process and matters needing attention for alarm threshold setting are, however, not provided in detailin the standard. It was discussed in this paper, with problems encountered in practical work.

Key words: Nuclear Power Plant, Site Radwaste Treatment Facility, Radioactive Liquid Effluents, On-line Monitoring, Alarm Thresholds
