摘　　要：针对某研究堆乏燃料元件,设计了新型密集贮存架。贮存单元采用正三角形布置,最大化地利用贮存架的有效空间;通过中子吸收体材料,降低整个系统的次临界度,从而实现乏燃料元件的高密集贮存。分析表明,乏燃料贮存格架在贮存容量、临界安全、物理热工以及强度安全等方面均满足中国相关法规及标准的安全要求。This paper designs a new type of intensive storage rack for a spent fuel element in a research reactor.The storage unit is arranged in equilateral triangle to maximize the effective space of the storage rack and the neutron absorber material is used to reduce the subcriticality of the whole system,so as to realize the high density storage of spent fuel elements.The analysis shows that the storage capacity,critical safety,physical thermal engineering and strength safety of spent fuel storage grid meet the safety requirements of relevant regulations and standards of China.
