核电厂液态流出物中63Ni的排放、剂量评估及监测方法研究

摘要/Abstract

摘要： ⁶³Ni是核电厂液态流出物中排放量较大的核素,在排放的裂变产物和活化产物中占比在10%以上,但我国核电厂目前对液态流出物中的⁶³Ni没有开展监测,没有相关监测数据的积累。本文在核电厂排放的⁶³Ni的来源分析及国外压水堆核电厂排放统计参考值调研的基础上,对⁶³Ni排放的剂量评估和测量方法进行了分析研究,并提出我国核电厂开展液态流出物中⁶³Ni监测的建议。

关键词: 核电厂, 流出物, ⁶³Ni, 监测, 剂量评估

Abstract: ⁶³Ni is one of the main radionuclides with more than 10% of the total activity for all fission products and activation products in liquid effluent from nuclear power plant (NPP), but until now in China there is no monitoring data for ⁶³Ni in liquid effluents from NPPs. On the basis of the discharge sources of ⁶³Ni and the reference values of discharge statistics in nuclear power plants of pressurized water reactors abroad, the dose assessment and the measurement methods for ⁶³Ni were investigated and monitoring of ⁶³Ni in liquid effluents discharged from nuclear power plants in China is proposed.

Key words: nuclear power plant, liquid effluents, ⁶³Ni, monitoring, dose assessmen
