Development of Radiation-Hardening Ceramic Composites for Fusion Applications
This Progress Report describes work performed as a collaborative effort between Rensselaer Polytechnic Institute (RPI) and Oak Ridge National Laboratory (ORNL). This research is focused in four areas considered to be critical issues for using SiC fiber-reinforced SiC matrix composites (SiC/SiC) as structural materials in a fusion environment: (1) Calculation of the critical dose and temperature for amorphization of SiC by using the TRIM computer code to analyze ORNL and literature data; (2) Measurement of irradiation-induced creep in monolithic SiC or stoichiometric SiC fibers; (3) Determining the effects of high-temperature irradiation on monolithic SiC as part of ORNL's METS experiment; and (4) Gauging the effectiveness of polymer impregnation pyrolysis in improving SiC/SiC composite hermicity. Progress in each area is described, as well as plans for next year.
