NWIS signatures for confirmatory measurements with B33 trainers
- Oak Ridge National Lab., TN (United States)
Nuclear weapons identification system (NWIS) signatures have been used successfully to confirm that B33 trainer parts in their M102 containers, shipped from military bases to the Oak Ridge Y-12 Plant, were as declared by the shipper to be nonenriched uranium. The verification was accomplished by comparing signatures for B33 trainer parts with signatures for mock-ups made with depleted uranium packaged at the Oak Ridge Y-12 Plant in M102 containers. These verifications were conducted in a timely, reliable manner and produced no false positives for the 512 verifications. NWIS signatures have been demonstrated to be adequate for shipper-to-shipper confirmatory measurement within the US Department of Energy (DOE) and between the US Department of Defense (DOD) and DOE. A nonintrusive use of NWIS signatures is demonstrated and would allow the use of this method by foreign nations at DOE or DOD facilities. A field-deployable system, based on a laptop personal computer system, is under development. Although the NWIS method was developed for nuclear weapons identification, the development of a small processor now allows it to be also applied in a practical way to subcriticality measurements, nuclear fuel process monitoring and quantitative nondestructive assay of special nuclear material.
