摘要
文章讲述了氢冷发电机中氢气的作用、氢气泄漏的原因及可能造成的危害,介绍了发电机氢气泄漏率的计算方法。以田湾核电站2号机组T203大修后氢气系统查漏为例,讲述了漏点查找过程,并介绍了2010年5月4日,1号机组升功率过程中氢气干燥器浮子流量计破损漏氢事件,阐述了对于发电机漏氢事件,电站工作人员应如何进行处理。
This article mainly explains the role of hydrogen in the generator of Tianwan Nuclear Power Station,the cause of hydrogen leakage and its potential risk. It also introduces the calatlating method for leak rate of hydrogen. It describes the process of inspection and determination of leak location, for example the inspection for locating the leak l^s~ition in the hydrogen system after TNPS T203 refueling outage, cites the event of hydrogen leakage owing to the damage of floating flow meter of hydrogen drier during Unit 1 power increase on May 4, 2010, and recommends how the NPS work personnel should deal with the generator hydrogen leakage event.
