Silicon carbide (SiC) has recently attracted much attention as a potential material for accident tolerant fuel cladding. To investigate the performance of SiC in severe accident conditions, study of steam oxidation at high temperatures is necessary. However, the study focusing on steam oxidation of SiC at temperatures above 1600⁰C is still certainly limited due to lack of test facilities. With...
Uranium silicide fuels have been proposed as part of accident tolerant fuel concepts for light water reactors. Uranium silicides (U3Si2 and U3Si5) have increased uranium atom density over UO2 fuel and thus their use can offset neutronic losses from more robust replacements for current zirconium-based cladding. Further development of such...
The EPRI code FALCON MOD01 has been used at PSI for about two decades for both research purposes and safety analyses, and is still undergoing developments. Namely, its coupling to the advanced fission gas release and swelling module (GRSW-A) module allowed the developments of several methodologies such as void formation by high temperature restructuring and burst fission gas release in RIA...
