| 摘 要： | 对CAP1400反应堆的吊篮与围筒旁通流量进行实验研究，研究了不同直径的围筒底板开孔下旁流腔的阻力特性及对应原型堆堆芯压降下的旁流份额。研究结果表明，当围筒底板开孔直径大于等于1.2倍的最小实验测量直径时，旁流腔的流量份额超过了对应原型堆堆芯压降下总流量的0.5%，其余孔径下旁流腔的流量份额均小于对应原型堆堆芯压降下总流量的0.5%。

| Abstract: | An experiment concerned with bypass flow between core barrel and core shroud was carried out . Not only resistance characteristics of bypass flow but also bypass mass flow rate proportion corresponding to original pressure drop of core under different orifice diameters of core shroud support plate were investigated .It is found that w hen orifice diameter is 1.2 times larger than the minimum orifice in experiment , bypass mass flow rate exceeds 0.5% of total core mass flow rate under reference core pressure drop condition .Otherwise the bypass mass flow rate is less than 0.5% of total core mass flow rate under other orifice diameters conditions . |
