一种压水堆燃料组件可拆连接结构研制

Research and Development of A New Speediness Disassembly Tie-In for Advanced Fuel Assembly

简要介绍压水堆燃料组件的结构,分析可拆接头存在的问题和需满足的技术特征。在此基础上重新提出一种压水堆燃料组件可拆连接结构的设计方案,并根据实验件的验证结果对结构进行优化。优化后连接结构的实验表明,多次拆装后每个试验件均可实现转动灵活、锁紧可靠、拆装便捷、具备互换性等设计要求。

This paper briefly introduces the pressurized water reactor fuel assembly structure, and analyzes the detachable joint problems and technical features. On this basis, a design scheme of connection structure of PWR fuel detachable is proposed, and based on the experiment results, the structure is optimized. Experiment on the optimized structure shows that after repeated disassembly, each test piece can satisfy the design requirement on flexible rotation, reliable locking, convenient disassembly and assembly, and exchangeability.
