压水堆回路与空间的放射性计算方法

本文讨论了压水堆一回路、二回路及回路空间的放射性来源及计算方法。其中包括水的固有活性,杂质活性,腐蚀产物活性和裂变产物活性。讨论了当蒸汽发生器有破损时带有放射性的一回路水向二回路泄漏引起二回路及其设备房间空气中出现放射性的过程及其计算方法。

A Method of the Calculaton of Radioactivity in the Pwr Loops and Equipment Rooms

This paper is devoted to the discussion of the radioactive sources from the primary loops,secondary loops and the equipment rooms of the presurred water reactor and a suggestion is proposed about the calcula- tion mathod.Among the various radioactive sources are the intrinsic activities,impurity activities,triton activities,corrosion product activi- ties and fission product activities,It has also been taken into accunt that the radioactive material would be leaked from primary loops into the secondary system and equipment rooms when the vapor Ieaked from the vapor generation.
