Testing of high temperature materials within HTR program in Czech Republic

Research institutes and also industrial companies in Czech Republic are involved in High Temperature Gas Cooled Reactor (HTGR) program and activities related to the study of advanced materials and HTGR technologies. These activities are supported by EC (within international projects, e.g. FP7-ARCHER, ALLIANCE, GoFastR can be mentioned) and also by Technology Agency of Czech Republic. | Testing of high temperature materials within HTR program in Czech Republic EPJ Nuclear Sci.

Research institutes and also industrial companies in Czech Republic are involved in High Temperature Gas Cooled Reactor HTGR program and activities related to the study of advanced materials and HTGR technologies. These activities are supported by EC within international projects e.g. FP7-ARCHER ALLIANCE GoFastR can be mentioned and also by Technology Agency of Czech Republic. Within these activities degradation of metallic and ceramic materials in the high temperature helium atmosphere is investigated and also new experimental facilities for material testing are built. As examples of tested materials Alloy 800 H ferritic steel P91 austenitic steel 316 Inconel 713 and 738 and corundum ceramics could be named. The selected results of exposure experiments in the high temperature helium environment are presented in this paper. 1 Introduction about the device. Another large research infrastructure and also two new helium loops is planned to be built in Czech research organizations universities and industrial Czech Republic within the SUSEN project 3 . The program companies are involved in High Temperature Reactor of testing the compatibility of metallic alloys with high HTR and also Gas Fast Reactor GFR Research temperature HTR helium coolant refers to previous program. The examples of these .
