Research on Decay Heat Calculation and Measurement for Pool-Type Research Reactor

Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang, Sichuan, 621900, China

摘要: 采用量热法测量反应堆额定功率运行75.0 h停堆后45 h内的衰变热功率,拟合出归一化衰变热功率的经验关系式。与反应堆衰变热几种半经验公式和标准对比结果表明,实验结果在经验公式计算值范围内,并与EJ/T 745标准预测值符合较好。

Abstract: The heat-measurement method is adopted to measure the decay heat of a nuclear reactor during 45.0 hours after the rated power operation of 75.0 hours;an empirical formula is fitted according to the experimental data.Several calculation empirical formulas used to calculate the residual power of a nuclear reactor and comparison with the test result indicated that the heat-measurement method could be used to measure the decay heat of a reactor,and the data is conformed to the standard of EJ/T 745.
