The fuel cycle discharge made towards several technical goalsburnup was modeled as calculated as part of this research involved withfrom a 3-batch linear reactivity model increased enrichment of PWR fuelassumption, with 3% leakage, and above 5%. We performed pin-cell levelresults showed a 10.9 MWd/kgU/% lattice calculations using the SCALEslope with enrichment. Further, code to accomplish an investigation ofincreasing enrichment resulted in a the fuel cycle length, beginning-of-lifehardening BOL and EOL neutron spec-(BOL) and end-of-life (EOL) neutrontrum and the reactivity coefficients spectra, reactivity coefficients, as wellwere shown to remain comfortably as the fuel burnup, the fission gasnegative (Figure 1) for all the enrich-(krypton and xenon) and Pu contentment cases considered.
