项目摘要

This programme will develop a new generation of creep-resistant Intermetallic Dispersion Strengthened 'IDS-steels', capable of withstanding the demanding operating requirements of Generation IV reactors, Advanced Modular Reactors (AMR), and Advanced Technology Fuels (ATF). The interlinked UK-India team comprises researchers from Birmingham, Bangor, Manchester, IGCAR and BARC, supporting early career researchers, and two-way research and academic visits.In order to meet the UK and India's future energy demand and decarbonisation commitments under the Paris Agreements nuclear energy will be of vital importance. Both the UK and India are developing future Generation IV nuclear fission technologies that would reduce the cost and waste production of nuclear energy, whilst being intrinsically 'walk away' safe. Gen IV reactor designs employ advanced coolants, such as molten metal (e.g. Na), molten salt, or gas coolants, which require high operation temperatures of 500-800 degrees C. This is significantly higher than current water cooled reactors, and as such requires advanced structural materials with increased capability over those currently employed.A variety of advanced materials are under consideration and development to meet the needs of Gen IV reactors and their more aggressive conditions (coolant chemistry, temperature and radiation damage) when compared to current reactors. Despite major successes there remains significant challenges to obtain the required balance of properties for Gen IV advanced reactors and a continued need to develop new materials.A material that has shown significant promise and has opened up a new research area is Oxide dispersion strengthened (ODS) steels, developed over the last 30 years. However, there remains challenges related to manufacturability on commercial scales. In the last decade there has been rapid development of advanced intermetallic reinforced steels for non-nuclear, with exceptional improvement in properties. This has been driven by great improvement in materials modelling, namely atomic scale modelling (DFT) and thermodynamic databases (CALPHAD), allowing for acceleration of the alloy development process. In this work we propose a new approach learning from the successes of nuclear ODS-steels, non-nuclear intermetallic reinforced steels, and the advances in materials modelling. A new generation of creep-resistant ODS-like 'Intermetallic Dispersion Strengthened' 'IDS-steels' will be developed capable of withstanding the demanding operating requirements of Generation IV reactors.Two-way knowledge exchange between the UK and India is a core part of this proposal such that long-lasting connections are developed that go beyond the duration of grant. This is highlighted throughout the Work Packages where expertise from both sides are combined. These strong interlinks will be ensured by bi-yearly visits of 1-2 weeks alternating between the UK and India including embedded researcher time in the resective labs, quarterly UK meetings including conference calls to India, with the findings of the project then presented at an open end-of-grant UK-India workshop.

该计划将开发新一代抗蠕变金属间弥散强化“IDS钢”，能够承受第四代反应堆，先进模块化反应堆（AMR）和先进技术燃料（ATF）的苛刻操作要求。英国-印度联合研究团队由来自伯明翰、班戈尔、曼彻斯特、IGCAR和BARC的研究人员组成，为早期职业研究人员提供支持，并进行双向研究和学术访问。为了满足英国和印度未来的能源需求和巴黎协定下的脱碳承诺，核能将至关重要。英国和印度都在开发未来的第四代核裂变技术，这些技术将降低核能的成本和废物产生，同时本质上是“走开”安全的。第四代反应堆设计采用先进的冷却剂，例如熔融金属（例如Na）、熔融盐或气体冷却剂，其需要500-800摄氏度的高操作温度。这明显高于当前的水冷反应堆，因此需要先进的结构材料，其性能超过当前使用的材料。各种先进材料正在考虑和开发中，以满足第四代反应堆的需求及其与当前反应堆相比更具侵略性的条件（冷却剂化学，温度和辐射损伤）。尽管取得了重大的成功，但在获得第四代先进反应堆所需的性能平衡方面仍然存在重大挑战，并且继续需要开发新材料。一种显示出巨大前景并开辟了新研究领域的材料是氧化物弥散强化（ODS）钢，该材料在过去30年中得到了开发。然而，仍然存在与商业规模上的可制造性相关的挑战。在过去的十年中，先进的非核金属间化合物增强钢得到了快速发展，性能得到了显著改善。这是由于材料建模的巨大改进，即原子尺度建模（DFT）和热力学数据库（CALPHAD），从而加速了合金开发过程。在这项工作中，我们提出了一种新的方法，从核ODS钢，非核金属间化合物增强钢的成功，并在材料建模的进展学习。将开发新一代抗蠕变ODS类“金属间弥散强化”“IDS钢”，能够承受第四代反应堆苛刻的运行要求。英国和印度之间的双向知识交流是该提案的核心部分，以便开发超越赠款期限的持久连接。这一点在整个工作包中得到强调，其中结合了双方的专门知识。这些强有力的相互联系将通过英国和印度之间的1-2周的两年一次的访问来确保，包括在各个实验室的嵌入式研究人员时间，包括印度电话会议在内的季度英国会议，然后在开放的资助结束时提交该项目的调查结果英国-印度研讨会。
