SST engineers designed and installed the first waterside security system on a commercial nuclear plant, it was hailed as the new industry standard. In this project, SST engineers defined the waterborne threat, conducted bathymetry and sound propagation studies in the local environment and developed a fiber-optic intrusion detection and assessment method to protect cooling water intake systems at the facility. The system operated better than originally expected with extremely high probability of detection with a very low false and nuisance alarm rate. The system was designed to detect divers and swimmers to prevent the introduction of explosive devices into the cooling water intakes of the plant facility. The system was integrated into the plant alarm monitoring stations and with assessment devices. Following installation, the team conducted extensive red-team testing and determined the system had a very high probability of detection and an extremely low false alarm rate. Plant staff relied heavily upon the system to detect waterborne attacks for the remainder of the plant’s operating years. Every facility has unique security needs that cannot be solved with a single, standard solution. SST works with the customer to determine the need and surpass expectations.
