秦山核电厂蒸汽发生器水位控制试验

简要介绍了蒸汽发生器水位控制系统的运行方式和试验方法。试验项目包括旁通阀控制试验、主给水阀控制试验和旁通阀与主给水阀的切换试验。文中给出了试验结果,即在液位扰动和核动率扰动时,蒸汽发生器液位的变化过程。经过两个月的运行和瞬态试验,证明蒸汽发生器水位控制系统满足设计要求。

Level Control Test of Steam Generator for Qinshan Nuclear Power Plant

This paper introduces operation models and the test method of the steam generator level control system. Items of the tests are following: control test with the bypass valve, control test with the major feedwater valve and change-over test between bypass valve and major feedwater valve. By the power operation and transient test for two months, it is shown that the performance of the steam generator level control system is satisfactory. As the result, the steam generator's level change on the condition of the disturbance of level and nuclear power is given.
