Burst Safety Analysis of Strengthened FeCrAl Claddings in APR1400 Fuel Rods Subject to LOCA Conditions

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%.

Modeling the Precipitation of Aluminum Nitride Inclusions during Solidification of High‐Aluminum Steels

steel research international, Volume 95, Issue 11, November 2024.
A model for the evolution of size distributions of AlN inclusions during the solidification of steel is proposed. The model is applied in high‐Al steels and validated by experimental data in literature. The influence of cooling rates and Al and N concentrations on AlN precipitation is described by the model.
