Evaluation of Physical Protection Elements for Interior Applications

Considerable emphasis has been given in recent years to the threat of sabotage or theft by an insider at nuclear facilities, a threat inherently different from that by outsiders. Special safeguards compatible with facility operations, safety, and maintenance programs are needed to counter the insider's unique knowledge and access to vital material and equipment. To help identify elements that meet these needs, field evaluations were performed on an interior access control system, piping sensors, interior video motion detectors, and valve monitoring devices. Both technical and operational evaluation data were obtained from tests in a realistic operating environment. Safeguards elements and operational test results and evaluations are described.
