摘要：
In order to grasp the torque characteristics of reactor coolant pump (RCP) under two-phase conditions, a special test platform was built in this study to carry out experimental research on a model pump based on the scale model of RCP. Firstly, the single-phase flow characteristics of the pump with multi-speed under normal condition, reverse pump condition, positive and negative energy consumption condition, obverse and reverse turbine condition, etc. were obtained. Then, the pump under single-phase air and two-phase 0.1-0.9 void fraction (the void fraction span is 0.1) was tested for the above conditions one by one. The proportionality law was used to sort out the experimental data at multiple speeds, and the variation rules of the torque under different void fractions, different flow rates and different conditions were obtained. Based on the data, homologous curve suitable for the primary circuit safety analysis software can be obtained simultaneously. The results show that with the increase of void fraction, the torque under the same condition decreases continuously, and the proportionality law curve drifts to zero gradually, while the homologous curve has the process of "degradation" first and then regression. When the void fraction reaches about 0.7, the degree of "degradation" reaches the maximum. © 2023 Atomic Energy Press. All rights reserved.
