摘　　要：带有可移动反射层的小型反应堆由于反射层的位移会导致反应堆功率测量产生偏差。基于分析这种偏差问题产生的成因与特性,针对性地提出了“工作组+补偿组”双组核探测器的测量补偿方案。实施结果表明,应用该方案后基本消除了可移动反射层对核功率测量带来的影响。The reflector movement of the small reactor with movable reflector will lead to the deviation of the reactor power measurement.Based on the analysis of the causes and characteristics of this deviation problem,a measurement compensation scheme for a"working group+compensation group"dual group nuclear detector is proposed.The implementation results indicate that the application of this scheme has basically eliminated the impact of movable reflector on nuclear power measurement.
