Development and performance of the advanced containment and surveillance system at the fast critical facility FCA

A personnel portal monitor was developed for IAEA safeguards at the fast critical facility FCA. The main components of the portal are (1) a walk-through metal detector, (2) a visual surveillance system with closed-circuit television and video-tape recorders, (3) tamper-indication system, and (4) remote monitoring capability through the RECOVER system. The metal detector can detect a single coupon of metallic nuclear fuel plate (2 in. x 2 in. x 1/16 in.) regardless of the orientation of a plate relative to the direction of travel inside the metal detector. The field tests of Phase I and Phase II were conducted jointly by the IAEA and JAERI to evaluate the various features and performance of the portal. (author)
