压水堆燃料组件安全运行保障措施分析

Analysis of Measures for Safe Operation of PWR Fuel Assemblies

通过对燃料组件进行设计、制造、运行、辐照后检查多方面的分析,提出当前保障燃料安全运行体系改进的方向,特别提出加强燃料组件拆卸检查、池边检查、热室分析的建议。对于自主化燃料组件,从燃料棒下端部防止磨蚀、改进防异物设计、增强组件结构强度等方面提出了相关建议。

Analysis on fuel assembly design, manufacture, operation and post irradiation examination are performed, and the improvement of current safe operating insurance is proposed. In particular, the proposal of strengthen disassembly inspection, pool side inspection and hot cell analysis of fuel assembly is put forward. Suggestions are also proposed for the fuel assembly development on self-reliance, including preventing abrasion at lower part of the fuel rod, improving the design of anti-debris and strengthening the strength of the component structure.
