Description
This paper describes an automated fuel element scanning system, based upon gamma-ray spectroscopy, that has been developed at the Oak Ridge Research Reactor. The scanning system is located in the reactor pool and allows fuel elements to be scanned nondestructively at various intervals during their core life. Gamma-ray measurements are made using a GeLi detector positioned above the pool water. Measurements of 137Cs count rates from relatively 'cold' elements indicate that the counting data obtained using this apparatus is reproducible within 5%. Power distribution in the reactor's core is derived from 140La counting data. The method of determining power is discussed briefly and some example results are presented.
