摘　　要：^(63)Ni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^(63)Ni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^(63)Ni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^(63)Ni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^(63)Ni监测的建议。^（63）Ni 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 ^（63）Ni in liquid effluents from NPPs. On the basis of the discharge sources of ^（63）Ni and the reference values of discharge statistics in nuclear power plants of pressurized water reactors abroad,the dose assessment and the measurement methods for ^（63）Ni were investigated and monitoring of ^（63）Ni in liquid effluents discharged from nuclear power plants in China is proposed.
