反应堆探测器孔道的计算分析

CALCULATING ANALYSIS FOR THE MONITOR HOLES IN THE REACTOR

摘要: 针对反应堆物理设计中探测器孔道的设置,提出了计算模型和计算方法,并作了实际计算。结果表明,探测器孔道的设置使安全壳外和混凝土壳外的中子通量和γ通量都会增大,对屏蔽是有影响的。在屏蔽设计中应考虑它的影响,以确保反应堆的安全。

Abstract: Calculating model and method for the reactor physics design of the disposition of monitor holes are presented.The calculated results with this model show that the disposition of monitor holes increases the neutron flux andγflux out of the containment and concrete shell,and their effects in the shielding design should be accounted for.
