【摘要】：一次屏蔽计算对于评估工作人员的辐射剂量、确保反应堆压力容器(RPV)及堆内构件在整个反应堆寿期内的安全性、防止混凝土屏蔽体及其外部部件和结构被过度活化具有重要意义。本文推导了TORT程序三维源分布计算公式和源几何转换方法,编写了相应的程序模块,并在秦山一期、CAP1400和CAP1700计算模型上进行了验证和应用。结果表明,本文推导的理论模型和开发的程序是正确的,为后续提高一次屏蔽设计精度提供了基础。
[Abstract]:A shielding calculation is used to evaluate the radiation dose of the workers to ensure the safety of the reactor pressure vessel (RPV) and the reactor components throughout the reactor lifetime. It is important to prevent concrete shield and its exterior parts and structures from being overactivated. In this paper, the calculation formula of 3D source distribution and the method of source geometric transformation for TORT program are derived, and the corresponding program modules are compiled, and verified and applied on the calculation model of CAP1400 and CAP1700 in the first phase of Qinshan. The results show that the theoretical model and the program developed in this paper are correct and provide a basis for improving the precision of primary shielding design.
