ATLANTIC Accident ToLerANT fuels reCycling

项目摘要

ATLANTIC is a broad ranging, multi-discipline programme that will focus on the very real challenge facing the UK and worldwide nuclear industry; that of how to implement accident tolerant fuels into our existing reactor fleets.To deliver this programme we are building on a close knit community of expertise that was created in EPSRC's PACIFIC programme and we have brought together a team of over 20 experts from 12 leading universities in the field of nuclear fission.Our team has already established close collaborative links with EU FP7 programmes such as SACSESS and ASGARD; strengthening the breadth and depth of expertise and allowing a continuing presence on the H2020 programme GENIORS. The UK has started on NIRAB R&D programmes in fuels and recycle; which look at the future of nuclear fission for the UK. Four of the Universities contributing to these programmes are part of the ATLANTIC team.ATLANTIC will create a foundation for implementing developmental work on ATF, but will also promote fundamental science on fuel behaviour, manufacture, separations and process kinetics.The programme is built around five interconnected work packages focussing on the scientific and engineering challenges, with two supporting work packages that provide programme governance and create collaborative links.Work package 1: "fuel - separations interface" will answer a number of research questions concerning the balance between recyclability and accident tolerance, particular knowledge gaps being: (1) What are the mechanisms of oxidation of ATFs under a range of conditions encountered throughout the fuel cycle but especially headend; and (2) how do the products of dissolution impact on advanced aqueous separations processes in development such as the Advanced PUREX, i-SANEX and GANEX processes. WP1 is led by Prof. Colin Boxall (Lancaster).Work package 2: "effects of contaminants on separations" will target the GANEX and iSANEX process, investigating the effects of contaminants on speciation, e.g. Cr3+ and Np redox. WP2 is led by Prof. Laurence (Reading).Work package 3: "investigation and optimisation of accident tolerant fuel materials" focuses on the optimisation and manufacture of accident tolerant fuel materials, and is broken down into three sub-packages: fabrication of ceramic fuels in pelletised form (U3Si2 and UN); materials characterisation and performance under lab conditions; and the effects of radiation damage on their properties and how this may modify in-reactor behaviour. WP3 is led by Prof. Karl Whittle (Liverpool).Work package 4: "fuel behaviour, non-stoichiometry and the fuel-water interface" will build an understanding of the how these fuels react in aqueous environments in the event of pin rupture during operation and/or subsequently during long-term storage and disposal. WP4 is led by Dr. Ian Farnan (Cambridge).Work package 5: "integrated management of accident tolerant fuels" will develop integrated separation technologies, by combining novel liquid-liquid intensified reactors and process control, which can be used in the recycling and reprocessing of metals and the production of nuclear fuel. WP5 is led by Prof. Panagiota Angeli (UCL).Work package 6: "networking and collaboration" will provide a focal point for dissemination of the research results and to reach out to international organisations where complimentary activities can be carried out through collaboration. WP6 is led by Dr Clint Sharrad (Manchester).Work package 7: " programme governance" will provide the necessary support to the team to ensure that the links between the work packages are effective by providing overview and advice from external experts and regular contact between team members. WP7 is led by the two principle investigators for the programme, Profs. Bruce Hanson (Leeds) and Tim Abram (Manchester).

大西洋是一个广泛的，多学科的计划，将集中在非常真实的挑战面临英国和世界各地的核工业;即如何在我们现有的反应堆群中实施耐事故燃料。为了实施这一计划，我们正在建立在EPSRC的PACIFIC计划中创建的紧密联系的专业知识社区，我们汇集了来自12所领先大学的20多名专家组成的团队我们的团队已经与SACSESS和ASGARD等欧盟FP 7计划建立了密切的合作关系;加强了专业知识的广度和深度，并允许继续参与H2020计划GENIORS。联合王国已开始NIRAB在燃料和再循环方面的研究与发展计划，该计划着眼于联合王国核裂变的未来。参与这些项目的四所大学是ATLANTIC团队的一部分。ATLANTIC将为实施ATF的开发工作奠定基础，但也将促进燃料行为，制造，分离和过程动力学的基础科学。该计划围绕五个相互关联的工作包建立，重点关注科学和工程挑战，工作包1：“燃料-分离接口”将回答关于可再循环性和事故容忍度之间平衡的若干研究问题，特别是以下知识差距：（1）在整个燃料循环过程中，特别是在头端遇到的各种条件下，ATF的氧化机理是什么;（2）溶解产物如何影响正在开发的先进水分离工艺，如先进PUREX、i-SANEX和GANEX工艺。第一工作组由Colin Boxall教授（兰开斯特）领导。第二工作组：“污染物对分离的影响”将针对GANEX和iSANEX工艺，研究污染物对物种形成的影响，例如Cr 3+和Np氧化还原。第二工作组由Laurence教授（阅读）领导。第三工作组：“事故容限燃料材料的研究和优化”集中于事故容限燃料材料的优化和制造，并分为三个子项目：（U3 Si 2和UN）;材料表征和实验室条件下的性能;以及辐射损伤对它们的性质的影响，以及这可能如何改变反应堆内的行为。第三工作包由卡尔·惠特尔教授（利物浦）领导。第四工作包：“燃料行为、非化学计量和燃料-水界面”将了解这些燃料在运行期间和/或随后在长期储存和处置期间发生销钉断裂时在含水环境中的反应。第4工作包由Ian Farnan博士（剑桥）领导，第5工作包：“耐事故燃料的综合管理”将开发综合分离技术，将新型液-液强化反应堆和过程控制相结合，可用于金属的回收和后处理以及核燃料的生产。第五工作组由Panagiota Angeli教授（伦敦大学学院）领导，第六工作组：“网络与合作”将提供一个中心，以传播研究成果，并与国际组织联系，通过合作开展互补活动。第六工作组由克林特·夏拉德博士（曼彻斯特）领导，第七工作组：“方案治理”将向小组提供必要的支持，通过提供外部专家的概述和建议以及小组成员之间的定期联系，确保工作组之间的联系有效。WP7由该计划的两名主要研究人员领导，教授。布鲁斯汉森（利兹）和蒂姆艾布拉姆（曼彻斯特）。
