一、概述中国科学院原子能研究所研究性重水反应堆,于1958年开堆时发现,当反应堆处于满负荷的正常运行状态时,重水泵的磨损指示器中气体增长非常迅速,经十五分钟即将指示器充满(约0.3升);当重水泵在1500转/分运行时,气体增长的速度更加显著。试验证明,气体是来自反应堆内部。由于活性区液面气泡层的存在,会降低反应堆的反应性并影响重水泵的正常工作。
I. Overview The CAS heavy water reactor, which was discovered in 1958, found that when the reactor was in normal operation at full capacity, the gas in the wear indicator of the heavy water pump grew very rapidly and was about to be indicated after 15 minutes (About 0.3 liters); when the heavy water pump is running at 1,500 rpm, the rate of gas growth is even more pronounced. Experiments show that the gas is from inside the reactor. Due to the existence of the bubble layer in the active zone, the reactivity of the reactor will be reduced and the normal operation of the heavy water pump will be affected.
