Title: Detection of missing rods in a spent BWR fuel assembly by computed gamma emission tomography

Abstract

This paper reports on a computed gamma emission tomography system that has been constructed which allows detection of the cross sectional rod pattern of BWR fuel assemblies. The under water detection head constructed is remote controlled by a laptop computer and it is housing two SiLi detectors. By scanning 32 to 48 views, the position of the water filled inner rod could be clearly detected in each of the three assemblies with cooling times of 2, 4 and 8 years using gamma rays of Pr-144 or Eu-154.
