Appendix R Security Upgrades
Generating Capacity: 2 Units, 2,282 MW
Scope of Services
Day & Zimmermann (D&Z) performed planning, scheduling, and complete installation services for the NRC-mandated Appendix R security upgrades. This fast-track project included a new perimeter video system with 97 fixed, infrared, and pan/tilt/zoom cameras. More than 145 craft and staff personnel worked more than 350,000 hours without any safety incidents.
The D&Z team installed more than 16,000 linear feet of perimeter trenching, more than 100,000 linear feet of underground Future-flex fiber-optic armored cable, and the following new equipment.
Video capture system
Access control system with computer work stations
Hand geometry units
Security badge card readers (142 throughout the plant)
Personnel infrared scanners
A significant number of underground passive pathway impairments (large concrete and steel bunkers) were encountered where tunnels or large-diameter piping passed from the protected area to the owner controlled area. Numerous defensive firing positions and concealment fences were installed in various locations throughout the plant.
