Safeguards-security (2S) complementarity is specified in the areas where the synergistic effects could be expected. Some possibility of joint use of measuring devices is considered. For example, at reprocessing plant, tank level gauges are used for detection of diversion by IAEA safeguards, for detection of theft by state authority, and monitoring operation status by operators. If the specification of sensors (sensitivity, time response, etc.) is satisfied the requirement, they could use the raw data from such sensors jointly. This situation might avoid the duplication of sensor installation and bring cost benefit. Synergistic effect on all types of future nuclear facilities can be expected based on '2S by Design'.
