摘　　要：重水堆核电站辐射防护的重点是氚内照射。秦山第三核电厂借鉴国外同类型电厂的经验，结合本厂运行和管理特点，初步建立了电厂的氚内照射辐射防护管理模式。本文从设计、运行过程、作业过程、工作人员防护等方面介绍秦山第三核电厂对氚的控制和防护措施，从场所监测、人员氚内照射剂量监测等方面介绍氚监测方法；给出了2003～2006年电站氚内照射剂量的监测结果，并与国外同类型电站进行了比较。Tritium internal exposure contributes to personnel dose more significantly in PHWR than in PWR and BWR. As the first PHWR in China, Third Qinshan Nuclear Power Plant （hereafter as ＂TQNPP＂） keeps developing radiation protection on tritium internal exposure, based on the operation experience of foreign PHWR plants and the practice of TONPP. This paper briefly introduces the tritium hazards and radiation protection on tritium hazards related to design, operation, work control, personnel protection at TQNPP. The personnel dosimetry results on tritium internal exposure from 2003 to 2006 show that the radiation protection on tritium hazards at TQNPP is effective, which makes the personnel internal exposure dose lower than other CANDU plants.
