全压堆芯补水箱（ＣＭＴ）是ＡＣ６００压水堆非能动高压安注系统的主要设备。全压堆芯补水箱补水实验主要研究中、小破口失水事故时ＣＭＴ的重力排放特性，为验证安全分析计算机程序提供试验数据。中国核动力研究设计院建造了ＣＭＴ补水实验装置，并在该装置上模拟反应堆主管道中、小破口失水事故动态工况，完成了ＣＭＴ补水实验。本文给出了小破口失水事故工况堆芯补水箱补水试验结果与分析。
The full pressure core recharge tank (CMT) is the main equipment of AC600 PWR passive high voltage safety injection system. Full-pressure core recharge tank recharging experiment Mainly studies the gravity discharge characteristics of CMT in the event of a small-breakage dewatering accident and provides experimental data for verifying the safety analysis computer program. China Nuclear Power Research and Design Institute built a CMT hydration test device, and in the device to simulate the reactor main pipe, small break water loss dynamic dynamic conditions, completed the CMT recharge experiment. In this paper, the results and analysis of the recharging test of the reactor core recharge tank under the condition of small breakwater loss accident are given.
