Since the accident at Fukushima, one major goal of reactor safety research has been the development of more accident tolerant technologies, coupled with other thermal hydraulic methods that can mitigate or delay fuel degradation during a Beyond Design Basis Accident. One major effort has been focused on the development of claddings and coatings for light water reactor fuel cladding. FeCrAl cladding, Chromium-coated Zircaloy clad are of the leading options. In this work, the MELCOR systems code (version 1.8.6 UDGC) is used to evaluate the performance of FeCrAl cladding and Cr-coated Zircaloy clad as compared to Zircaloy clad for a Pressurized Water Reactor, PWR (i.e., Surry) for a Station Blackout (SBO) accident scenario. Passive cooling and FLEX engineered the system, such as core recovery cooling injection and auxiliary feedwater injection, are also considered during the ATF performance analysis for extra copying time. Our future work is focused on the uncertainty analysis of the oxidation rate data, coating failure criteria, and severe accident modeling limitations in order to better quantify ATF (Accident Tolerant Fuels) clad benefits.
