Analysis of the Causes and Solution Measures for Crevice Corrosion on the Blind Plates of the Generator Stator Water Cooler in a Certain Nuclear Power Pplant
During the corrosion inspection of a nuclear power plant's major overhaul,corrosion was found on the blind plate of the generator stator water cooler.This article analyzes the corrosion of the blind plate from two aspects:corrosion morphology and corrosion resistance.It is concluded that the material of the generator stator water cooler blind plate is 304 stainless steel,which has poor corrosion resistance in seawater environment,resulting in crevice corrosion of the blind plate.To solve the problem of crevice corrosion on the blind plate,corresponding measures are proposed in this article to effectively solve the problem and ensure the normal operation of the equipment.This provides a reference for the maintenance and management of nuclear power station power generation equipment.
