核燃料组件运输容器应用现状概述

目的 充分了解国内外核燃料组件运输容器的主要应用现状，通过对照国外发展经验，为更好地实现国内运输容器自主化发展提出意见建议。方法 调研和分析国际上主要核大国代表性核燃料组件运输容器的技术现状，以及国内容器的研发、应用状况，梳理了自主化发展中仍需改进的方向。结果 国际上主要核大国利用核能技术较早，均已针对本国的反应堆技术开发了成熟的运输容器产品，相比之下，目前国内在引进和吸收国外先进技术的基础上，也已逐渐实现了部分核燃料组件运输容器的国产化，并针对高温气冷堆开发了新型运输容器。结论 建议注重核燃料组件运输容器的系列化发展，增加攻克关键技术的投入，继续推进容器设计评价软件开发与试验验证平台的建设。

Overview of Application Status for Nuclear Fuel Assembly Transport Package

The work aims to fully understand the main application status ofnuclear fuel assembly transport packages at home and abroad and put forward suggestions based on the experience of foreign countries so as to realize the independent development of domestic transport packages. The technical status of representative fuel transport packages in major nuclear countries as well as the domestic R&D and application status were surveyed and analyzed. The directions that still need to be improved in independent development were viewed. Main nuclear countries in the world developed the nuclear energy industry earlier and have formed mature transport package products for their own reactor technologies. At present, on the basis of introducing and absorbing foreign advanced technology, the domestic development of some nuclear fuel assembly transport packages had been gradually realized. The new type transport package for high-temperature gas-cooled reactor fuel assembly had been developed. It is recommended to pay more attention to the serialized development of transport packages and increase the investment in overcoming key technologies. The development of package structure design software and the construction of the test platform need to be strengthened.
