Progress in Development of Containment and Surviellance Systems at JAERI

Several of Containment and Surveillance (C/S) systems have been developed for the international safeguards at JAERI. This paper describes the recent progress in the development of the following C/S systems: (1) Compact CCTV surveillance system \"COSMOS\" is designed as a potential replacement for IAEA twin minolta film camera system. COSMOS has the capacity to record more than 30,000 still pictures for three months by battery operation without battery change. An unique one-shot Video Tape Recorder (VTR) was developed for COSMOS based on commercial 8mm VTR. Prototype of COSMOS was completed in October 1986, and demonstrated the expected performance. (2) FCA portal and penetration monitor is the comprehensive C/S system developed for the fast critical facility of JAERI. The system was completed in 1985. The field trial test of the entire system was started in September 1986 under real field conditions using regularly scheduled inspectors performing actual inspections to obtain performance data and to gain international credibility.
