Sandia National Laboratories’ Z-Machine is the world’s most powerful electrical device, and experiments have been conducted that make it the world’s most powerful radiation source. Because Z-Machine is used for research, an assortment of materials can be placed into the machine; these materials can be subjected to a range of nuclear reactions, producing an assortment of activation products. A methodology was developed to provide a systematic approach to evaluate different materials to be introduced into the machine as wire arrays. This methodology is based on experiment specific characteristics, physical characteristics of specific radionuclides, and experience with Z-Machine. This provides a starting point for bounding calculations of radionuclide source-term that can be used for work planning, development of work controls, and evaluating materials for introduction into the machine.

A methodology for calculating a bounding estimate of contamination from the Z-machine accelerator (p, n) reactions with metal alloy wire arrays is presented.
