This paper focuses on the impact of some parameters of the irradiation history on the total neutron emission of a SFE. The tool used to determine the neutron emission was the ORIGEN-ARP code. The cases considered a Low Enriched Uranium (LEU) 17×17 PWR fuel with an initial enrichment of 4.5%. The burnup ranged between 5 and 70 GWd/tU and 30 values of cooling time, from 0 up to 3 million years, were considered. The parameters that were varied were the average power level, the cooling time between cycles and the duration of the irradiation cycle. The obtained neutron emission values are presented and discussed. Conclusions on the role of the considered irradiation history parameters on the total neutron emission and on the impact of the main neutron emitters are drawn.
