Steam oxidation of FeCrAl coated Zircaloy-2
… fferential scanning calorimetry (DSC). Bare and FeCrAl coated Zircaloy-2 nuclear fuel cladding and FeCrAl coated single crystal Yttria stabilized Zirconia (YSZ) samples were oxidized in an argon/steam environment at 700 C and 1100 C. FeCrAl coated Zircaloy-2 was also heated to 1200 C in an inert …

Characterization of Iron-Chromium-Aluminum surface coated Zircaloy-2 under high temperature steam
Iron-Chromium-Aluminum (FeCrAl) thin films have been deposited on Zircaloy-2 (Zry2) and yttria-stabilized zirconia (YSZ) by magnetron sputtering, and they have been tested with respect to the oxidation weight gain in high temperature steam. In 700C steam environment, the FeCrAl-coated Zry2 samples …

Estimation of coping time in pressurized water reactors for accident tolerant fuel claddings
… ATF claddings, monolayer iron-chromium-aluminum (FeCrAl) and Cr-coated Zircaloy, are experimentally investigated. Specifically, this work investigates the high-temperature oxidation characteristics of FeCrAl alloy after exposure to 1000-1400 °C steam for 1 hour. A model for oxidation of FeCrAl …

Using MELCOR with enhanced predictive capabilities via Thermochimica to model two severe accident cases of a generic BWR with Zry-2 and FeCrAl
… Case I: Zircaloy-2 cladding, and Case II: FeCrAl cladding. The results from these two cases were analyzed using a one-way coupling approach with Thermochimica to demonstrate potential areas for the improvement o fMELCOR’s current material modelling capabilities.

BULK NANOSTRUCTURED STEELS FOR NUCLEAR REACTOR AND EXTREME ENVIRONMENT APPLICATIONS
<p>"Candidate accident tolerant FeCrAl fuel (ATF) claddings for light water reactors (LWRs) need to be thinner than current Zircaloys owing to higher neutronic penalty, demanding an improvement in strength. Therefore, equal channel angular pressing (ECAP), and high-pressure torsion (HPT) were used …

Application of advanced fuel concepts for use in innovative pressurized water reactors
… materials are examined: stainless steel (SS), FeCrAl alloy, molybdenum (Mo) and SiC CMC, each having its own development time and costs. The chosen cladding thicknesses were dependent on strength and manufacturing constraints. It was found that all options may end up requiring higher enrichment …
