Abstract

An analysis is given of uncertainties in fission reaction rate ratio measurements in the NBS standard neutron fields. These are of interest to those involved in fast reactor cross-sections, LWR pressure vessel surveillance dosimetry, and similar measurements in the Oak Ridge Pool Critical Assembly. The new, more detailed analysis leads to lower standard deviations than were reported previously. It also indicates correlations between measurements and could serve as a guide for future documentation of experiments.
