The purpose of this study is to look into the feasibility of creating fuels for the APR1400 that are accident-tolerant. It will substitute other materials, such as FeCrAl and SiC, for the current Zr fuel-cladding system. In order to increase the safety margin of pressurized water reactors, the study investigates the characteristics and neutronic behavior of fuel-cladding systems to determine their neutronic performance. Centerline temperatures, 239-Pu inventories, pin power distributions, and thermal neutron flux spectra are just a few of the many features of the two systems that are examined and contrasted with a Zr-based fuel cladding system. Additionally, several fuel combinations' reactions to the burnable poison rod Gd2O3 are investigated. Additionally, the characteristics of the SiC fuel cladding system are similar to those of the conventional Zr-based systems, which lead to enhanced safety and economic benefits.
