| 摘 要： | 为了准确分析核设施停机后周围空间的三维辐射剂量场分布情况,基于严格两步法(rigorous two step method,R2S)停堆剂量计算的方法,开发了基于蒙特卡罗输运计算程序MCNP5和燃耗计算程序ORGEN2. 1耦合的三维停堆剂量计算程序M OCA,实现了中子输运计算、材料活化计算和光子剂量计算的自动耦合,并通过中子辐照例题与Super MC程序进行对比验证,结果表明MOCA的计算结果与Super MC计算的结果吻合较好,可以为核设施的运维检修以及退役的剂量率空间分布提供参考数据。

| Abstract: | In order to accurately analyze the three-dimensional radiation dose field distribution in the surrounding space after the nuclear device is shut down.This work develops a three-dimensional radiation dose calculation program MOCA based on Monte Carlo transport calculation program MCNP5 and the burning consumption calculation program ORGEN2.1,realized the automatic coupling of neutron transport calculation,material activation calculation and photon dose calculation,and compares the results with the SuperMC program through the neutron irradiation example.The results show that the results of MOCA are in good agreement with those of SuperMC,which can provide reference data for the operation and maintenance of nuclear facilities and the spatial distribution of dose rate of decommissioning. |
