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。 相似文献

To investigate the long-term operating efficiencies of container ports, we extend the work of previous researches to present a new systemic and improved method of data envelopment analysis (DEA)-based Malmquist productivity index (MPI) in this paper. An approach based on both panel data and multi-inputs/outputs is considered comprehensively, and aims at measuring the operating efficiencies of 10 leading container ports in China from 2001 to 2006 by applying this new systematic calculation method. The results illustrate that the main influence factor of total factor productivity change is the technology change, and the container transportation of these 10 ports is on the healthy development status and will recover and grow reposefully in the following years. 相似文献
