Overview The Continuous Automated Vault Inventory System (CAVIS™) is a system designed to continually monitor the status of stored nuclear materials from remote locations. The system includes an integrated set of low-cost sensors that are capable of monitoring specific item radiation, weight, and temperature attributes. It is also capable of handling information from other remote sensing devices or systems (e.g., SmartShelf™ and ReflectoActive™ Seals). Features Nuclear material inventories can be conducted without accessing material Inventories can be completed without any radiation exposure to personnel All significant attribute changes can be immediately reported and acknowledged Multiple attribute monitoring can be accomplished for each item The system is adaptable to pre-existing nuclear material storage configurations The system is designed with multiple layers of security The system provides data authentication for independent auditing The system can also be adapted for monitoring a variety of other hazardous materials (e.g., mixed waste) System Operation CAVIS™ continually verifies specific item attributes weight, radiation, and temperature) from stored nuclear materials. It monitors these attributes for "change-in-state" by continually polling a network of devices called "sensor concentrators." Each sensor concentrator monitors the sensor package associated with each container of nuclear material and reports status to a central computer. The concentrators can be monitored by a desktop personal computer running either a National Instruments LabView® (Windows® 95) application or the GraFIC™ software package on a Windows® NT system. In this way thousands of items may be monitored from a single central site or by a distributed computing network operating in a client/server environment.
