Helium Leak Examination Technology on In-Service Condenser in Nuclear Power Plant
摘 要
凝汽器是核电厂汽轮机组的重要设备,在电厂凝汽式汽轮机组的热力循环中起着冷源的作用,其传热管在运行的过程中可能发生破管,从而引起二回路水质恶化。介绍了针对核电厂常规岛凝汽器破管的氦气泄漏检测方法。通过对在役凝汽器氦气泄漏检测方法的研究,掌握传热管破管的判断方法。现场检测结果表明,开发的检验技术应用效果良好,在保证核电厂安全、经济运行上起到了重要的作用。
Abstract
Condenser is the very important equipment in the steamship unit of the nuclear power plant and it plays a cooling effect on the heat circulation in the condensable steamship unit of the nuclear power plant. Pipe rupture in the process of operation might occur in its heat transfer canal and it will lead to the deterioration of water quality in the Second Circuit.This article introduced the helium leak examination method against the pipe rupture in the condenser in the steamship unit of the nuclear power plant, grasping the judgment method whether the pipe rupture occurs in heat transfer canal by researching the helium leak examination method on the in-service condenser. The on-site examination results indicated the developed examination technology apply well,it played an important effect on assuring the safety and economic operation of the nuclear power plant.
