我院设计的第五座微型反应堆,于1990年完成了零功率实验检验。通过元件法和水位法实验,确定了该堆的临界装载量以及在后备反应性有一定裕度条件下堆的实际燃料装载量。用元件-周期法检验了堆中心控制棒的效率不小于7.5×10~(-3)△k/k。检验了上铍反射层的积分效率和水位系数。
The fifth mini-reactor designed by our hospital completed the zero-power experiment in 1990. Through the component method and water level test, the critical load of the reactor and the actual fuel load of the reactor under a certain margin of the backup reactivity were determined. The element-cycle method was used to test the efficiency of the control rod of the heap center not less than 7.5 × 10 ~ (-3) △ k / k. The integration efficiency and water level coefficient of the beryllium reflector were tested.
