INNOVATIVE METHODS TO EXTEND THE SERVICE LIFE OF LEGACYSAFEGUARDS SURVEILLANCE SYSTEMS

摘要

The IAEA has developed an approach to retaining the serviceability of surveillance equipment atrnfacilities that have previously installed analog video surveillance systems. These systems havernprovided good service in the past, but are centered on analog videotape recorders that have longrnsince become obsolete and for which replacement components are no longer available or costrneffective. Reliability and availability issues make it impractical to attempt to maintain thesernsystems in their original configuration. Immediate replacement of these legacy systems withrnIAEA standard systems is also infeasible due to cost, the need for facility shutdown, and thernnormal period of negotiations. The Agency has therefore developed a phased approach tornupgrading the safeguards systems at these facilities with no loss of service. This approach isrnunique in that it uses standard Agency components in non-standard ways to accomplish thernobjective. This approach replaces the failing legacy components with combinations ofrncomponents from standard Agency systems while continuing to use those installed componentsrnthat are not reaching end of life. These Agency components will later be reconfigured and usedrnin the upgraded system as complete system replacement becomes feasible. Therefore, therninvestment in these components is not lost. This paper describes some of the approaches that thernIAEA is considering to economically maintain video surveillance within these facilities.
