摘　　要：概述了岭澳核电站一回路系统真空排气台架的设计方案、主要性能参数、相关的技术改造和运行过程等。设备现场运行表明,一回路系统真空排气台架可使一回路系统压力达到0.02 MPa以下,可在一回路系统充水排气过程中节约时间约30 h。一回路系统真空排气台架设计参数和运行参数均优于国外同类设备;该项技术替代了以前国内大型核电站无燃料水压试验充水前的多次静态排气及多次动态排气过程,在国内首次实现了大型核电站无燃料水压试验充水前的真空排气。This thesis describes the design scheme,main capability parameter,relative technical reform and operation process etc.of the vacuum releaser of the primary circuit system of LingAo nuclear power plant.After the vacuum releaser of the primary circuit system being operated on site,the pressure of the primary circuit system can be below 0.02 MPa.abs,it can save about 30 hours in filling water and draining air process of primary circuit system.The design parameter and operation parameter of the vacuum releaser of the primary circuit system are better than the similar equipment of foreign country.This technique replaces a number of previous processes of static and dynamic draining air in the large-scale domestic nuclear power plant before filling water of no-fuel hydrostatic test,it is the first time to realize the vacuum releasing air in the large-scale domestic nuclear power plant before filling water of no-fuel hydrostatic test.
