蒸汽发生器液位波动的原因分析及响应

Cause Analysis and Response of Fluctuation of Steam Generator Level

蒸发器连接一、二回路,肩负着冷却堆芯保证核安全,同时也产生蒸汽用于推动汽轮发电机组,从而将核能转变为电能,由此蒸发器的液位和压力控制显得至关重要,本文介绍功率运行期间蒸发器的液位控制,并简单分析蒸发器液位波动的原因以及如何诊断和响应。

Steam generator connects the primary and secondary loops,and ensures the core cooling and nuclear safety.At the same time,steam is generated to drive the turbine unit,thus converting nuclear energy into electricity.Therefore,the level and pressure control of steam generator is very important.This article introduces the SG level control during power operation,and briefly analyses the reasons of the SG level fluctuation and how to diagnose and respond to it.
