Radiation-Induced Segregation and Phase Stability in Candidate Alloys for the Advanced Burner Reactor

Abstract

Project Objective: The objective of this project is to determine the effect of irradiation on the segregation and phase stability in candidate alloys that may be used as structural materials for transmutation in the advanced burner reactor. This project will focus on ferritic-martensitic (F-M) alloys T91 and HT-9, an experimental oxide dispersion-strengthened (ODS) alloy, and an advanced austenitic alloy, D9, to investigate the electronic-magnetic-elastic interactions between chromium and radiation-induced defects. This project seeks to provide an understanding of radiation-induced segregation (RIS) and phase stability that can be used to develop predictive irradiation performance models.
