摘　　要：随着国内核电的快速发展,大量的乏燃料从反应堆中卸出,乏燃料的贮存问题具有迫切性与必要性。对高燃耗乏燃料贮存方法进行理论研究,设计了基于强制氦循环系统的乏燃料干式贮存综合台架。该系统包括冷凝、去湿、氦循环、密封容器四个模块,通过氦气循环对高燃耗乏燃料进行干燥与降温。本文对该系统进行模拟仿真验证与台架试验验证,利用仿真结果与试验结果进行相互印证,试验结果表明:该台架符合设计预期,能够在设计时间内通过氦循环系统对密封容器内部起到干燥及冷却的效果,为高燃耗乏燃料贮存提出了可行方法。With the rapid development of domestic nuclear power,a large amount of spent fuel is unloa-ded from the reactor,and the storage of spent fuel is urgent and necessary.In this paper,the theoretical research on the storage method of high burnup spent fuel is carried out,and a comprehensive bench for dry storage of spent fuel based on the forced helium cycle system is designed.The system consists of four modules:condensation,dehumidification,helium cycle,and sealed container,and it dries and cools down the high-fuel-consumption spent fuel through helium cycle.In this paper,the system is veri-fied by simulation and bench test,and the simulation results and test results are used to verify each oth-er,and the test results show that the bench meets the design expectation,and it is able to dry and cool the inside of the sealed container through the helium circulation system within the design time,and it puts forward a feasible method for the storage of high-fuel-consumption spent fuel.
