【摘要】 微堆存在二个潜在资源 ,即附加补偿棒和池水。在确保安全的前提下 ,可将它们挖掘并加以利用。设置附加补偿棒 ,把闲置的顶铍反射层的后备反应性加以利用并逐步释放。微堆为“罐 池”结构 ,运行时堆水与池水存在较大温差 ,2 7t池水可作为一大的冷源 ,通过池水中的螺旋冷却器冷却 1 4t堆水 ,可获得较多的温度效应。采取了这两项措施之后 ,可大大延长微堆的可连续运行时间 ,改善它的运行性能 ,拓宽了微堆的应用 ,提高其寿期内的价值更多还原

【Abstract】 After long term research, it is believed that there are two utilizableres resources in miniature neutron source reactor(MNSR) provided reactor safety is ensured:(1) The reserve reactivity in the top of berylliums shims can be absorbed by adding compensatory control pated, and then be released progressively. (2) Owing to the big difference in temperature between the reactor water and the pool water during reactor operation, 27 t pool water can be used as a large cool source for cooling the 1.4 t reactor water through the cooling coil in the pool, and the temperature effect gained therefore will externd MNSR successive operation time. These two measures will improve MNSR’s performance, widen out its adaptation scope, and add its value.更多还原
