Abstract
The Oak Ridge Sensors for Enhancing Nuclear Safeguards (ORSENS) program has developed technologies that are being incqorated into domestic and international safeguads applications. These technologies represent the latest in state-of-the-ar4 lowcost sensors for continuous remote monitoring of stored nuclear materials. me current suite of sensor technologies includes RADCouple~ (low power gamma scintillator), IV4DSiP~ (silicon p-i-n diode based), RADTeLL~ (CdZnTe semiconductor based), and FAS~ ( fiber-optic attribute sensing technology/gamma seintillator), along with a FAS~ neutron and three other neutron sensing technologies under development). ORSENS also has two weight sensors [one using SROF (silicone rubber optical fiber) and the other using eapaeitanee technology]. ORSENS System technologies include the Continuous Automated Vault Inventory System (CAVIS), the SmartShel@ item identitkation and transfer authentication system, and OTDR (optical time domain reflectometry)-based (continuously monitored) active seal system. Standardized hardware and customized software has also been developed to support this program.
