| Abstract Scope |
SiC/SiC is beneficial in many high-temperature applications and has been developed for aerospace and nuclear fission fuel cladding. For fusion, the challenges are different, including enhanced transmutation compared to fission, and very high radiation damage doses. The blanket environment also includes corrosive liquid metal coolants and breeders, although mechanical stresses are modest compared to aerospace and fission cladding.
This presentation will give an overview of SiC/SiC development at UKAEA including fusion-relevant irradiations to replicate transmutation production, and liquid metal corrosion. Results of micromechanical testing, radiation damage observed using TEM and Raman microscopy, and macroscopic mechanical testing will be covered. This leads into progress on developing “fusion grade” composites tailored to this environment including novel interphases and coatings. |
