摘要
核电厂厂区辐射和气象监测系统(KRS系统)用于监测厂区及周边γ环境剂量率是否存在异常变化。某核电厂针对KRS系统γ剂量率监测数据出现非正常波动,从发生的时间、频次,以及剂量率波动变化的趋势,通过分析和实验验证,确认KRS系统AS4子站点γ剂量率数据波动是由3MX、4MX厂房内射线探伤活动所致。
The radiation and weather monitoring system(KRS system)of nuclear power plants is used to monitor whether there are abnormal changes of the environmental gamma dose rate in the plant and its surroundings.From the time and frequency of occurrence,and the trend of fluctuations,through analysis and experimental verification,we confirmed that dose rate data fluctuations of the AS4 sub-sites of the KRS system in a nuclear power plant are caused by radiographic inspection activities in 3MX and 4MX workshops.
