Abstract
A safeguards closed-loop control system for plutonium nitrate transfer and sampling operations is described. This system, currently being developed by Sandia Laboratories, assures that all operational steps are performed in a predefined sequence and by the properly authorized individuals. A variety of protective elements are used in conjunction with computer controls and checks to rapidly detect unauthorized activities and activate controls, delays, or, where necessary, request response force actions. In-depth protection is provided against theft and diversion, particularly by individuals with authorized plant access. While this system is designed specifically for transfer and sampling of plutonium nitrate, the basic concepts are applicable to theft and sabotage protection of other operations involving SNM as well as facility vital systems.
