摘要: 分析研究了使微型中子源反应堆延长单次运行时间的几种改进方案。研究与实验结果表明,在中心控制棒与堆芯原有结构保持不变,不超过安全运行限值的情况下,在侧铍反射层外附加弧形补偿板,再添加适当当量的顶铍片后,中心控制棒与补偿板联动,可使微型中子源反应堆一次连续运行时间大大提高,提高了微型中子源反应堆的运行性能。Abstract: This paper analyzes some improvement plans to prolong the single operation time of the Miniature Neutron Source Reactor (MNSR). Test results shows that after adding proper quantity of Be plates on the top Be plates box, the single operation time of MNSR can be greatly prolonged by installing the compensation Cd-plate outside the flank Be-reflector and making the plate and central control rod move together, without any change of central control rod and the original structure of the reactor core. The operation performance of MNSR can be improved.
