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

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041

摘要: 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。
