Determination of oxidation rates and volatile oxidation products for HTGR graphite matrix material exposed to steam atmospheres

 
 
 
 

Abstract


Abstract High-temperature gas-cooled reactors (HTGRs) in operation use tristructural isotropic (TRISO) particles embedded in graphite and carbonized resin matrix to form the fuel element. This graphite matrix material serves as a supportive structural element, heat transfer medium, and neutron moderator. In HTGR designs, fuel compacts are exposed to helium coolant, which facilitates high outlet temperatures (750°C
