AP1000依托项目中压移动电源应用研究

Implementation Study of Medium Voltage Mobile Diesel Generator in AP1000 Project

福岛核事故后,世界各国对核电厂的安全十分关注,外部事件是否会引起核电厂大量放射性释放是关注的焦点。2012年,国家核安全局发布了《通用技术要求》,要求核电厂设置中压移动电源。针对AP1000依托项目非能动安全特性,选择中压移动电源为1E级蓄电池充电、需要时为正常余热排出系统(Normal Residual Heat Removal System,简称RNS)泵注射提供动力作为使用场景,给出了接入方案、规程以及试验条目等工程方案。

After the Fukushima nuclear accident,the safety of nuclear power plants has been paid close attention to all over the world.Whether external events will cause a large amount of radioactive release from nuclear power plants is the focus of attention.In 2012,the National Nuclear Safety Administration issued the General Technical Requirements,requiring nuclear power plants to set up medium voltage mobile diesel generator.According to the passive safety characteristics of the AP1000 project,the medium voltage mobile diesel generator is selected to charge the class 1E battery and provide power for RNS pump injection when necessary.The access scheme,procedures,test items and other engineering schemes are given.
