How many Sole Vouching Authorities (SVA) are allowed per exclusion area?

The correct answer indicates that only one Sole Vouching Authority (SVA) is permitted per exclusion area. This regulation is critical for maintaining clear accountability and minimizing confusion in operations within nuclear facilities. By designating a single SVA for each exclusion area, it ensures that there is a singular point of control and responsibility for vouching the status and security of items, access, and personnel in these sensitive areas. This approach enhances the management of nuclear security and safety protocols, allowing for more efficient communication and decision-making processes regarding nuclear surety. Having more than one SVA could lead to conflicting judgments and a lack of clarity regarding responsibilities, which is why limiting to one per exclusion area is a standard practice in the industry.
