Quick and Accurate Profile Monitor for Irradiated Fuel

摘要

A new instrument has been developed for the rapid measurement of the activity profile of irradiated fuel pins and assemblies. Through prototype examinations it has been shown that the profile shapes agree with the shapes as measured by an intrinsic germanium detector and a Be( gamma ,n) detector. This new technique can reduce the profile measurement time by more than an order of magnitude over existing measurement times. (ERA citation 04:040368)
