电子束氨法脱硫反应器内部剂量率的模拟计算

Simulation Calculation of Internal Dose Rate in EA FGD

为验证MCNP用于计算电子束氨法脱硫反应器内部剂量率的可行性,本文借用"小孔成像"的原理对能量为0.57MeV的电子加速器进行模拟,计算电子束氨法脱硫反应器内部的剂量率分布,并与文献中的实验测量值以及EGS4程序模拟值进行比较。结果表明:MCNP程序计算所得到的反应器内部剂量率分布在25.7%误差下的结果与EGS4程序模拟结果一致。

In order to verify the feasibility of MCNP for calculating the internal dose rate of an electron beam ammonia desulfurization vessel, the principle of "pinhole imaging" is employed to simulate an electron accelerator with energy of 0.57 MeV. The dose rate is then calculated, and compared with experimental measurements in the literature and the simulation values with the EGS4 program. It shows that the MCNP program calculation results at 25.7% error are consistent with those from the EGS4 program simulation.
