Abstract
The first Waste and Residue Nondestructive Assay (NDA) Measurements School was given at Los Alamos on June 3–7, 1996. This school is a new part of the DOE Office of Safeguards and Security, Safeguards Training Program, with additional instructor support from the National Transuranic Waste Program, Idaho National Engineering Laboratory, Oak Ridge National Laboratory, Portsmouth Gaseous Diffhsion Plant, Westinghouse Savannah River Company, Pajarito Scientific Corporation, and Canberra Industries. The school was attended by 22 safeguards and waste measurement personnel from DOE facilities, and included lectures on waste characterization requirements, the WIPP Performance Demonstration Program, waste and residue NDA techniques, and a workshop discussion on waste assay issues. Hands-on training modules with 55-gallon-drum waste assay systems were held using a Segmented Gamma-ray Scanner, a Tomographic Gamma-ray Scanner, two Add-a- Source Waste-Drum Assay Systems, a Californium Shuffler, and a Differential Die-away system that included Combined Therrnal-Epithermal Neutron Interrogation (CTEN). This paper will describe the new school and report on the measurement results obtained during the school with the above-mentioned wastedrum assay systems.
