大会简介: 作为一个乏燃料管理的决策者,采取一种整体的核燃料循环策略,确保核燃料循环的所有阶段的影响都清晰,并促进核燃料循环后端的有效决策。详细的挑战包括管理的灵活性,以适应未来乏燃料管理的方式(SFM)选择,以及定义和解决存储、运输和处置的相关问题。 目前,现在长时间存储后的乏燃料运输经验很有限。然而,随着存储时间的潜在扩展和许多国家干式储存设施的发展以及其他存储方式的出现,包括在储存、运输阶段使用双用途运输桶。存储和运输之间的过渡显得越来越重要—尤其是检查或再包装,以及安全方面。 2015年6月的会议将涵盖从乏燃料管理综合方法,旨在解决SFM对决策及核燃料循环其余阶段发展活动的影响。 大会主题: • Spent fuel management strategies: Interdependencies between the different steps of a strategy, lessons learned from Member States’ programmes, the information required to support successful strategy implementation, etc.; Experience in strategy development and implementation, engaging key interested parties in strategy development, managing uncertainties and interfaces; Different considerations for large and small nuclear power programmes; • Storage options in support of the integrated approach: Advantages and disadvantages of different options (e.g. centralized versus on-site storage, wet versus dry storage, single-use versus dual-purpose or multi-use casks); When, how and why to shift from one technology to another; International cooperation in developing spent fuel storage options. • Status and challenges in an integrated approach: Experience in designing and operating SFM facilities; Results of the Joint Working Group on Guidance for an Integrated Transport and Storage Safety Case for Dual Purpose Casks for Spent Nuclear Fuel; Transport/storage/reprocessing/disposal interfaces; Consequences on the availability of spent fuel disposal; Governmental, technical and legal/regulatory aspects of spent fuel storage, transport, reprocessing and disposal; Management of damaged fuel (storage, reprocessing, transport and disposal); Technological advances to accommodate changes in the nuclear fuel cycle; Security aspects of SFM. • Ageing management programmes: Surveillance and monitoring; Time limited ageing analysis; and How to develop an international database on ageing experience and ageing management plans. • Impact of the front end of the nuclear fuel cycle on the back end: Advantages and disadvantages of alternative fuels and revised reactor operation (e.g. new claddings, thorium fuels, high burnup fuel and mixed oxide fuel). • Research and development required to deliver an integrated approach: For example, current studies on hydrogen behaviour in zirconium cladding, drying of spent fuels, corrosion issues. • Safety aspects of spent fuel management: The licensing process for SFM (storage, transport after storage, reprocessing and disposal); Safety case development for the different steps of SFM; Safety and technological consequences of reprocessing (or not) spent fuel; Safety considerations for dual purpose casks. 详见网址: http://www-pub.iaea.org/iaeameetings/46528/International-Conference-on-Management-of-Spent-Fuel-from-Nuclear-Power-Reactors-An-Integrated-Approach-to-the-Back-End-of-the-Fuel-Cycle |
