Multiscale Modeling of Thermomechanical Properties of Ceramic Pebbles (KIT Scientific Reports ; 7573) [PDF]

, 2011
Ceramic pebbles are foreseen to be used as tritium breeder in helium cooled pebble bed blankets in fusion reactors. The pebbles are subject to high temperature and irradiation. They may fail during thermomechanical loading.
