Studying The Effect Of Using Some Burnable Absorber On PWR-1150 Fuel Using The Code GETERA

This analysis deals with the evaluation of the fuel burnup behavior for PWR-1150 reactor assembly by modifying with changing both, the number of fuel rod which have burnable absorber (BA) and the percent weight of BA in each rod. The achieved result presented in this paper enables determine the suitable structure of reactor assembly when fuel enrichment equal to 4.4%. The GETERA 90 code was used to perform assembly burnup calculation. For validation purposes they are compared with selected experimental data for similar reactor.
