EPR堆芯严重事故下安全壳内的辐射屏蔽计算
EPR containment radiation shielding calculation in the state of a severe accident
MCNP程序可以从粒子输运、扩散方程的角度来模拟计算堆芯在严重事故下安全壳内的辐射剂量水平。本文以EPR堆芯为例，采用MCNP 5程序及其核数据库CCC-710建立了精确的三维蒙特卡罗模型，在此基础上对EPR严重事故下安全壳内的辐射剂量率进行了计算分析，为判断堆芯情况和制定应急防护行动提供了数据参考。
By using MCNP code，containment radiation levels of EPR could be calculated in a way of particle transport or diffusion equation. A accurate 3D model of a EPR was built based on MCNP Version 5 and its nuclear databases CCC-710 in this paper. Theγ-Ray Dose Rates of EPR containment in the state of a severe accident were performed, which can also provide information for core damage judgment and response to the nuclear emergency.
