AP1000核电站氢气系统施工和调试要点分析

Analysis for Installation and Commissioning of the Hydrogen System in AP1000 Nuclear Power Plant

AP1000核电站氢气系统与其他核电氢气系统的区别就是,氢气系统既要向除盐水除氧提供低压氢气,又要向一回路直接注入高压氢气以维持还原性水化学环境;它们的共同点就是都向发电机提供冷却用氢气。本文介绍了在系统移交和调试试验过程中遇到的问题,针对这些问题,调试队所采取的良好实践进行简要介绍。

Compared with other hydrogen system,the hydrogen system of AP1000 nuclear power plant supply low pressure hydrogen to eliminate oxygen in the DWS(Demineralized Water System).It can also supply high pressure hydrogen to keep reduced environment in the RCS(Reactor Coolant System).Their common characteristic is they supply low pressure hydrogen to the generator.This paper talks about the problems when we are doing system turn-over and commissioning work.Facing these problems,JST take suitable measures to handle them.
