“华龙一号”非能动安全壳热量导出系统布置优化研究

Study on Layout Optimization of Passive Containment Heat Removal System of HPR1000

非能动安全壳热量导出系统(PCS)是我国自主设计的具有完整知识产权的第三代核电技术“华龙一号”中非常重要的一个非能动的安全系统,其通过布置在安全壳外部的换热水箱将安全壳内的热量导出到壳外的大气环境中,以这种自然循环的运行实现降低安全壳内温度和压力的目的。

The passive containment heat removal system(PCS)is a very important passive safety system in the third-generation nuclear power plant with independent intellectual property rights.The heat inside the containment is transferred through the heat transfer water tank outside the containment to the atmosphere,and the operation of this natural circulation reduces the temperature and pressure inside the containment.
