Multibadging reductions at the H.B. Robinson Nuclear Plant

Because of the uncertainties involved in high dose work at nuclear power stations, multibadging practices are often quite conservative---the main criterion is when in doubt, multibadge. An analysis of multibadging results from the 1986 refueling outage at the H.B. Robinson Nuclear Plant indicated that multibadging could be reduced if consistent criteria were used. This article reviews the guidance available on multi-badging for non-uniform radiation fields and presents a set of refined multibadging criteria, which incorporate minimum dose rate and integrated dose equivalent thresholds. When used to analyze the multibadging results from the 1986 outage, the criteria indicate that reductions in multibadging of 50% may be possible, without compromising the accuracy of whole-body dose equivalent measurements
