核电厂辐射指数评价模型构建

Construction of Radiation Index Evaluation Model for Nuclear Power Plants

通过确定反应堆厂房具有代表性的辐射测点,建立标准化的辐射监测方法准确获取测点的辐射数据,再计算和分析辐射指数从而定量评价机组的辐射水平变化规律,实践经验表明,辐射指数评价模型准确反映了机组辐射水平变化规律,在大修的辐射防护管理、辐射剂量控制、辐射异常调查和源项分析中发挥了重要作用,具有较强的实用价值,也可为其他电厂的辐射防护管理提供思路和借鉴。

Radiation index evaluation model establishes a standard radiation monitoring method to obtain radiation data of typical radiation spots in reactor buildings,then calculates and analyzes the radiation index to evaluate the fluctuation law of radiation level.The practice proved that the radiation index evaluation model can accurately show the fluctuation trend of radiation level of u-nits.The radiation index evaluation model has made a great effort in radiation protection manage-ment,radiation dose control,abnormal radiation events’investigation and source analysis,it has practical value and provides nuclear peers with ideas and references on radiation protection man-agement.
