滨海核电大件码头用于乏燃料运输的改造内容

Modification content of heavy cargo wharf at coastal nuclear power plant for spent fuel transportation

海运在内的多模式联运体系是未来乏燃料外运的发展方向。我国滨海核电厂在初期就规划、设计和建设了用于运输核电厂大件设备的码头,多模式联运体系可利用核电码头转运乏燃料。为满足乏燃料转运需要,经调研和分析,结合船舶靠离泊等条件进行综合评价,梳理出核电码头的改造内容。结果表明,各核电业主应聚焦核材料实物保护、船舶靠离泊条件、货包接卸工艺等方面,围绕码头平面尺度及结构、作业工艺、辅助生产设施和管理体系等内容开展核电大件码头的改造工作,以确保未来乏燃料能够及时外运。

Including transportation by sea,the multi-modal system is the future direction of spent fuel transportation.In the early stage of construction,coastal nuclear power plants have planned,designed and built heavy cargo wharf for large equipment transportation.Spent fuel can be transferred from the heavy cargo wharf in the multi-modal system.In order to satisfy the requirement of transferring spent fuel,we combine with the berthing and unberthing conditions of ships to carry out the comprehensive evaluation,sort out the modification content of nuclear power plant wharf after investigation and analysis.The results show that nuclear power plants should focus on physical protection of nuclear materials and ship berthing conditions and package loading technology to carry out modification of wharf by centering on wharf plane scale and structure,operation technology,auxiliary production facilities,and management system.To ensure that spent fuel can be shipped out on time in the future.
