摘要
根据三代核电设计准则要求,华龙一号堆芯中子注量率测量方式相对于M310堆型发生了根本性变化,从而导致探测器设计发生重大改变。本文针对华龙一号堆芯中子注量率的测量需求,对其堆芯中子注量率测量仪表选用的自给能中子探测器(SPND)的核、电性能关键参数进行研究和分析,并给出了SPND的设计方案。通过堆上试验验证,其性能满足华龙一号堆芯中子注量率测量的设计需求。
According to the requirement in the guidelines of 3 th generation nuclear power plant,the measure method for the in-core neutron flux in HPR1000 is changed fundamentally,resulting in great change in the design of the neutron detector.Based on the requirement of the in-core neutron flux measurement,this paper conducts the analysis and research on the key parameters which affect the nuclear and electric performance of SPND,and puts forward a design scheme of SPND.The test in the reactor proves that the design of the detector satisfies the requirement of the in-core neutron fluence measurement system.
