反应堆主屏蔽的设计与计算

Design and calculation for the main shielding layer of researching reactor

为使反应堆处于运行状态时 ,对辐射源的屏蔽满足辐射安全的要求 ,以及对堆的各部件和材料满足辐射限制的要求 ,必须设计堆的主屏蔽层。介绍了主屏蔽的设计与计算方法 ,以研究堆为设计实例 ,给出了主屏蔽的主要计算结果表明 ,以池水和重混凝土作生物屏蔽能满足辐射安全限值的要求 。

To satisfy the national safety criteria of the radiation shielding when the reactor is in operation, We must complete the design of shielding for the main body of reactor. This paper introduces the design and computing methods of the shielding for the main body of reactor, using the researching reactor as an example, and gives the results of the computing for the radiation shielding. The results show that it can satisfy the safety criteria of radiation to use water and heavy concrete as biological layer for radiation, so the design of the main layer for radiation shielding is reliable.
