The High Temperature Materials program supports the HTGR design and licensing process. The thermal, environmental, and service‑life conditions of the HTGR will make selection and qualification of the high temperature materials a significant challenge; thus, new materials and approaches may be required.
Objectives of the High Temperature Materials program include the following:
Expansion of the materials and design ranges allowed by the ASME Code for HTGR applications
Characterization of significant in‑service degradation mechanisms, definition and development of inspection needs and associated procedures
Development of methods and structural data to address high temperature design methods and materials issues identified by the regulatory body, as well as the Advisory Committee on Reactor Safeguards (ACRS), in order to preempt hurdles in the HTGR licensing process
Support of selected university materials‑related R&D activities that would directly benefit the HTGR
Support of international materials‑related collaboration activities through the DOE‑sponsored Generation IV International Forum (GIF) Materials and Components Project Management Board (PMB).
