The disposal of the waste stored in single-shell tanks at the Hanford Site is recognized as a major environmental concern. A comprehensive program has been initiated to evaluate the various alternatives available for disposal of these wastes. Theses wastes will be disposed of in a manner...

The segmented gamma scanner has become an important instrument for assaying the special nuclear material content of low-density scrap and waste in 55-gal. drums. To perform these assays accurately, we need appropriate standards to calibrate the response of the system including the detector...

This paper addresses a series of studies undertaken while fulfilling the measurement requirements for certification of a 55-gallon drum-sized segmented gamma scanner to be used at the plutonium facility (TA-55) at Los Alamos. These studies were initiated to investigate anomalies seen in the data...
