摘　　要：中子噪声用于反应堆冷却剂沸腾监测有独特的作用。本文使用 Wach- Kosaly的理论模型，比较成功地解释了堆芯中冷却剂的沸腾引起的中子噪声，通过对压水堆局部沸腾零功率堆模拟实验的计算与分析，得出了判断汽泡上升速度的物理量。The neutron noise method has been used to monitoring reactor coolant boiling.In this article,Wach- Kosaly model has been used to interpret the neutron noise induced by coolant boiling.The equation based on the model is got and used for calculation.The physical variable with the relation of bubble's velocity is got from the calculated result (autopower spectral density).
