Safety Non Safety Unit 1 Review Related Related Interface System Eagle 21 Plant Computer While Eagle was installed prior to Unit 1 (ICS) Licensing, the interfaces to the ERFDS/P2500 main frame computers were analog. With the replacement of the ERFDS/P2500 mainframes by the Integrated Computer System (ICS), the interface became digital. Since ICS was installed under 50.59 the Unit 1digital communications interface has not been reviewed.

Common Q Plant Computer Common Q is not installed in Unit 1 (ICS)

Unit 2 Interface Review The digital Eagle to ICS interface in Unit 1 is via node boxes on a ring network. The interface for Unit 2 is direct from the Eagle cabinets to a network switch on a star network. While the Unit 2 ICS computer hardware interface is different than Unit 1, the Eagle interface is the same in both units; via a mono-directional communication path described in Reference 1. Due to the difference in the ICS connection, the Unit 2 interface is unique.

The Common Q to Plant Computer interface is via the safety related Maintenance and Test Panel (MTP) fiber optic interface which blocks all except the minimum low level TCP/IP commands necessary to support communications. A detailed description of the MTP communications is contained in WNA-LI-00058-WBT, Revision 0, Watts Bar Unit 2 (WBN2) Post Accident Monitoring System (PAMS) Licensing Technical Report submitted under Reference 2. Additional communication isolation is provided by non-safety related data diodes (one for each train). The Common Q to ICS interface is unique to Unit 2.
