国外NUHOMS乏燃料干法贮存系统管理研究及启示

Research and Inspiration on Management of Dry Storage of NUHOMS Spent Fuel

摘要: 为妥善管理核电发展产生的乏燃料，世界各核电大国在水池湿法贮存和干法贮存方面投入了大量研发，美国研发的NUHOMS干法贮存系统。该技术路线作为模块化的压水堆乏燃料干法贮存技术，应用于美国的很多核电厂，本文在阐述NUHOMS干法贮存系统组成与操作流程同时，概要分析了美国在乏燃料贮存设施的安全监管、许可审查、容器评审与取证、法规体系建设等方面的情况，在总结国外相关经验的基础上，结合国内目前在干法贮存设施管理方面存在的不足，提出了相关的管理建议和意见。

Abstract: Those developed countries with nuclear power have made a great devotion to developing the tech-nology of Spent Fuel storage in order to manage Spent Fuel safely, especially in the dry storage and wet-pool storage. Being a Module system, NUHOMS dry storage system, which was developed by Transnuclear Inc. of the US, has been applied to many NPPs in the US among those storage technol-ogies. This paper gives a brief introduction to component and operation progress of NUHOMS dry storage system, also, analyzes the management experience in spent fuel storage facilities in the US, such as safety supervision, licensing review, container assessment and legislation system. After making a conclusion on experience abroad, the paper gives some suggestions and advice based on the management shortage of spent fuel storage facilities.
