Abstract

This report contains details of the experimental procedures used by NPL during a trial run for an international comparison of thermal neutron fluence rate measurement. A description is given of the measurements which were performed at NPL using the thermal column facility. Also described are the analysis technique and the various corrections applied. The characteristics of the transfer instrumentation proposed for this comparison are discussed. The results for the ratio of the measured fluence rate to the transfer detector count rate are given together with a detailed breakdown of the uncertainties.
