MatDB Online analysis of HTR materials data from European R and D

Recent high temperature reactor (HTR) concepts for nuclear co-generation foresee hot gas temperatures up to 850 °C. While suitable materials for the high temperature exposed components well-known from conventional technologies are taken into consideration, extended material qualification tests must still be performed for reactor design and licensing to guarantee safe and economic operation. For this purpose data management tools are required. For administration of materials data coming from European R and D projects the Joint Research Centre – Institute for Energy (JRC-IE) offers the web-enabled MAterials DataBase (MatDB Online) free of charge to the European research community. It represents a comprehensive tool for storing, retrieving and evaluating materials test data together with related documentation in a linked document management database (DoMa). MatDB Online hosts materials data from the former German high temperature reactor programme and was, respectively is involved in several GENeration IV (GEN IV) reactor systems related European R and D projects such as HTR-M/M1 (high temperature reactor materials) and RAPHAEL (reactor for process heat, hydrogen and electricity generation) and the cross-cutting project GETMAT (GEN IV and transmutation materials). The paper gives an overview of MatDB Online and DoMa as a central storage system for European R and D materials data and documents, describes the HTR materials and the data content within MatDB Online, and gives evaluation examples of HTR materials data. Noting the data transfer obligations within GIF (GEN IV International Forum), the paper concludes with recommendations for further materials testing.
