Abstract

This manuscript presents important material challenges regarding innovative Gen-II/III nuclear systems and research reactors. The challenges are discussed alongside the key achievements so far realised within the framework of 4 EU-funded projects: H2020 IL TROVATORE, FP7 MULTIMETAL, FP7 MATTER and FP7 SCWR-FQT. All the four Projects deal with innovative researches on materials to enhance the safety of nuclear reactors. IL TROVATORE proposes new materials for fuel cladding of PWR reactors and tests in order to really find out an “Accident Tolerant Fuel” (ATF). MULTIMETAL focused on optimization of dissimilar welds fabrication having considered the field performances and dedicated experiments. MATTER carried on methodological and experimental studies on the use of grade 91 steel in the harsh environment of liquid metal cooled EU fast reactors. SCWR-FQT focused on fuel qualification of Supercritical Water Reactor including the selection of the better material to resist the associated high thermal flux.

创新的第II/III代和研究反应堆的燃料和材料

这份手稿提出了关于创新的第II/III代核系统和研究反应堆的重要材料挑战。这些挑战与迄今为止在4个欧盟资助项目框架内实现的关键成就一起进行了讨论：H2020 IL TROVATORE、FP7 MULTIMETAL、FP7 MATTER和FP7 SCWR-FQT。所有四个项目都涉及对材料的创新研究，以提高核反应堆的安全性。IL TROVATORE提出了用于压水堆燃料包壳和测试的新材料，以真正找到“事故容忍燃料”（ATF）。MULTIMETAL专注于异种焊缝制造的优化，同时考虑了现场性能和专门的实验。MATTER对在液态金属冷却的欧盟快堆的恶劣环境中使用91级钢进行了方法和实验研究。SCWR-FQT专注于超临界水反应堆的燃料鉴定，包括选择更好的材料来抵抗相关的高热通量。
