| 摘 要： | 本文介绍一个自行编制的用于计算压水堆核电站在常规运行工况下气载放射性物质向环境释放量的计算机程序ＭＧＡＬＥＳ。采用ＯＲＩＧＥＮ２程序，根据燃料元件的成份和燃耗情况计算堆芯的放射性核素谱；用放射性物质经堆芯向一回路迁移的逃脱率系数计算一回路冷却剂中的放射性核素浓度；再考虑核电站实际运行过程中一、二回路冷却剂的泄漏以及通风、除气等过程，计算其正常运行工况下气载放射性物质向环境的释放量。

| Abstract: | A computer code,MGALES,to calculate the release amount of gaseous ra-dioactive effluents from PWR nuclear power plant under normal operation conditions is intro-duced in this paper. The ORIGEN2 code was adopted to calculate the radioactive spectra in PWR core, and the escape rate of radionuclides from fuel element to primary coolant wasused to calculate the radioactive concentration in primary coolants. In combination with theleakage from primary and secondary coolants and the process of building ventilation and e-quipment degasification,the radioactive release amount of gaseous effluents from PWR un-der normal operation condition to environment was calculated. |
