Effective multiplication factor and fuel temperature coefficient calculations of PWR assembly under different temperatures

Öz

This paper presents effective multiplication factor (keff) with different burnable absorbers and weight percentages at different temperatures as well as doppler coefficient results and number density calculations for Westinghouse type pressurized water reactor (PWR) Assembly. Integral fuel burnable absorber rods coated with ZrB2 and Gadolinia-Uranium (UO2-Gd2O3) integral burnable absorbers were considered to calculate reactor parameters (keff and doppler coefficient). The results compared with base fuel which does not contain burnable absorber at different temperatures. The results show that reactivity was decreased with increased temperature and doppler coefficients increased with temperatures but remained negative at all temperatures. At 1500 K, the effective multiplication factor for base fuel was found to be 1.46985 while the effective multiplication factors for 2% with Gd2O3, 8% with Gd2O3, and IFBA rods were 1.38976,  1.37574, and 1.30337 respectively.
