【摘要】：福清核电厂1号机组凝结水精处理系统因系统水压试验失当,造成五台混床出水装置出水孔板全部脱焊,导致五台混床均不可用。其中2#混床受损最严重,已经无法修复。采用守恒原理,结合当时福清核电厂1号机组二回路的实际情况,经计算得出:在凝结水精处理系统三台混床投用时,机组功率可升至75%FP;在凝结水精处理系统四台混床投用时,机组可满功率运行;凝结水精处理系统由四用一备正常运行模式改为四用零备的特殊稳态运行模式可以满足福清核电厂1号机组首次核燃料循环的需求。
[Abstract]:Due to the improper hydraulic test of the condensate treatment system of Unit 1 of Fuqing Nuclear Power Plant, the outlet plate of the outlet water of five mixed-bed units is completely dewelded, resulting in the unavailability of all the five mixed-bed units, in which the damage to the mixed-bed is the most serious. The principle of conservation is adopted and combined with the actual situation of the second loop of Unit 1 of Fuqing Nuclear Power Plant at that time, it is calculated that when the three mixed-bed are put into use in the condensate precision treatment system. Unit power can rise to 75 FP; When the four mixing beds are put into use in the condensate treatment system, the unit can operate at full power. The condensate fine treatment system can meet the needs of the first nuclear fuel cycle of Fuqing Nuclear Power Plant Unit 1 from the normal operation mode of four-use one-standby system to the special steady-state operation mode of four-use zero standby system.
