Non-RF Chain of Custody Item Monitor (CoCIM) Development Report
- Sandia National Laboratories (SNL), Albuquerque, NM, and Livermore, CA (United States)
The Chain of Custody Item Monitor (CoCIM) developed by Sandia National Laboratories is one of the most mature and well-studied active seals for use in containment applications for arms control treaty verification and international nuclear safeguards. However, its typical design includes wireless communications provided by a radio frequency (RF) transmitter and receiver. While this provides flexibility of movement for many applications, it is unnecessary and undesired for some treaty verification applications. This report details the design and construction of two variants of the CoCIM that remove the RF transmission capability in favor of directly connected wired and short-range infrared communications, as well as a new coordinator that is used to interface the CoCIM to a computer, and new interface software that is simplified for a likely inspection use case.
