Energy Science &Engineering, Volume 13, Issue 2, Page 728-741, February 2025.A computational framework is developed to evaluate the thermo‐mechanical performance of APR1400 fuel rods with FeCrAl claddings under normal and LOCA conditions. Results show that reducing the pellet‐cladding gap enhances heat conduction and burst safety, while an 80% strength enhancement in FeCrAl claddings improves burst safety by up to 80%.

Characterization of Alumina Scale Formed on FeCrAl Steel
Archives of Metallurgy and Materials, 2014 Abstract In this paper the morphology of the oxide scale formed at 850°C on the foil surface of FeCrAl steel is described. Two types of samples have been used: one covered with an Al nano-layer and the second without. Microscopic observations of the cross-sections of scales have demonstrated that in the case of foil without Al nano-layer there is ...
