RShieldMC程序计算核电厂辅助厂房屏蔽特性

Auxiliary Plant Shielding Character Calculation Based on RShieldMC Code

采用自主研发的辐射屏蔽专用蒙卡程序RShieldMC,结合可视化建模工具JLAMT,对某核电厂辅助厂房进行建模,计算辅助厂房屏蔽墙外光子剂量率,并将计算结果与MicroShield、MCNP程序计算结果进行比对。结果表明,RShieldMC计算结果与MicroShield、MCNP程序计算结果符合良好,验证了RShieldMC程序在屏蔽计算问题中的可靠性与工程应用性。

A dedicate radiation shielding software RShieldMC was developed based on Monte-Carlo method.The nuclear power plant auxiliary building was modeled via visual modeling software JLAM T and was used for the validation of RShieldMC.The Photon dose rates outside the auxiliary plant shielding wall were calculated by using RShieldMC code.The RShieldMC results were compared with that of MCNP and MicroShield codes.The calculation results of RShieldMC show a relatively good consistency with the MCNP and MicroShield results.The agreement of the results indicates the reliability and engineering application of RShieldMC in PWR shielding calculation.
