摘　　要：氚是核电厂放射性流出物中重要的核素,氚源项也是核电厂辐射环境影响评价中最重要的关注点之一。本文基于压水堆核电厂中氚的产生机理建立氚源项的计算模型,并结合我国某在役核电机组2003—2018年运行经验反馈数据,对理论计算模型的结果进行对比分析。研究结果表明,本文建立的氚的计算方法所得到的模拟值与实际运行情况相符,本文氚排放计算采用的计算模型和假设是合理的。Tritium is an important nuclide in the radioactive release of nuclear power plants.Tritium release is also one of the most important concerns in the radiation environmental impact assessment for nuclear power plants.Based on the generation mechanism of tritium for PWR nuclear power plants,the calculation model of tritium release is established.Combined with the operational feedback data from a nuclear power plant during normal operation in China in 2003-2018,the result of the theoretical calculation model are compared and analyzed.The research result shows that the simulation values obtained by the calculation method of tritium are consistent with the actual operation.The calculation model and assumption used in the calculation of tritium release are reasonable.
