Integral parameters for the Godiva benchmark calculated by using theoretical and adjusted fission spectra of 235U

Creators

Description

The theoretical and adjusted Watt spectrum representations for 235U are used as weighting functions to calculate Keff and θf28/θf25 for the benchmark Godiva. The results obtained show that the values of Keff and θf28/θf25 are not affected by spectrum form change. (author)

Abstract (Portuguese)

Os espectros teorico e ajustado de Watt para o 235U sao utilizados como funcoes de ponderacao para calcular K-efetivo e θf28/θf25 do problema-padrao Godiva. Os resultados obtidos mostram que os valores de K-efetivo e θf28/θf25 nao sao afetados pela mudanca na forma do espectro. (autor)
