Description

When calculating the effective delayed neutron fraction βeff for a given reactor system, the assumed delayed neutron group spectra and the assumed number of delayed neutrons born per fission νd can have a major impact on the final value. Over the years, the recommended values for the delayed neutron spectra and for νd have slowly changed. To ascertain whether or not these changes have increased the accuracy of βeff calculations in fast 235U systems, the authors have reevaluated βeff for the benchmark system Godiva-I using newly calculated delayed neutron spectra and Tuttle's recommended values of νd for both 235U and 238U
