Ceramic matrix composites are of interest for nuclear applications bec
ause of their high-temperature properties, corrosion resistance, fract
ure toughness relative to monolithic ceramics, and low neutron activat
ion and after heat. Evaluations of the radiation resistance of commerc
ially available SiC/SiC composites have revealed their promise for thi
s application, but also the need for further development to achieve th
e desired performance. This paper summarizes the results of a workshop
cosponsored by the Offices of Fusion Energy and Basic Energy Sciences
of the US Department of Energy and Lockheed-Martin Corporation with f
orty attendees from national laboratories, universities and industry.
A number of promising routes for optimizing the radiation stability of
ceramic matrix composites were identified at this workshop. These rou
tes included the newer, more stoichiometric fibers and alternate fiber
/matrix interfaces and matrix processing routes.
