压水堆燃料转运装置运输小车超载分析

Overload Analysis for Conveyor of PWR Fuel Transfer System

某核电厂某次装料前,燃料转运装置运输小车带载水下试验时,运输小车运动至燃料厂房侧(K侧)行程末端时小车出现驱动故障。本文从燃料转运装置运输小车及倾翻架结构出发,对出现的故障进行原因分析及处理,并优化预防性维修项目内容。

Before the loading of nuclear fuels in a nuclear power plant, in the underwater test of the conveyor of fuel transfer system, we found that the conveyor failed to drive when it moved to K side （fuel plant side） at the travel end. In this paper, the causes are analyzed and solved in terms of the structure of conveyor of fuel transfer system and upender, and the content of the preventive maintenance project is further optimized.
