反应堆竖直放置方案时,停堆工况和正常运行工况下,距离屏蔽体最外面一层2m处中光子剂量率小于200 mRem/h(2 mSv/h)为约束条件下的屏蔽体厚度。
When placing the reactor vertically, the thickness of the shielding body is constrained by a photon dose rate of less than 200 mRem/h (2 mSv/h) at a distance of 2 meters from the outermost layer of the shielding body under shutdown and normal operating conditions
