DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGES The Nuclear Regulatory Commission's " Safety Evaluation Report Fire Protection Program, North Anna 1 & 2", dated February',1979, requires the installation of additional fire protection systems in certain safety-related areas of the station. These systems have been installed by design change DC 78-68. The systems increase the protection provided to safety-related systems from the hazard of fire.

The purpose of the Technical Specification change is to update the existing Technical Specifications to reflect the new fire protection systems. These 1 changes are as follows:

I. FIRE DETECTORS In order to provide early warning of a fire additional smoke and fire detectors were installed throughout the station. Placement of the detectors were made after a study of the configuration of the area so that maximum protection could be realized. The additional detectors serve to increase the safety of the station and does not adversely affect plant safety or increase the possibility of an accident.

II. FIRE PROTECTION STANDPIPES To provide additional fire protection water supplies, fire hose stand-pipes and hose racks were added in the following areac:

(a) Auxiliary Building - Wet fire hose standpipe.

(b) Emergency Switchgear - Units 1 & 2 - Dry fire hose standpipe.

(c) Cable Tray Spreading Room - Wet fire hose standpipe.

(d) Reactor Containment - Units 1 & 2 - Dry standpipe system.

The addition of the above standpipes serve to increase plant protection due to a fire. The standpipes located in safety-related areas were l mounted to withstand a seismic event. Dry standpipes were installed where water could damage safety-related equipment. Therefore installa-tion of this equipment does not increase the possibility of an accident.

III. SPRINKLER SYSTEM In order to provide additional fire protection, sprinkler systems were installed in the following safety-related areas.

(a) Auxiliary Building Component Cooling Pump Area, Elev. 244'6" (common to Units 1 and 2).

(b) Auxiliary Building Component Cooling Pump Area, Elev. 259'6" (common to Units 1 and 2).

(c) Service Bailding Cable Vault, High Bay Area (manual system, open heads).

(d) Service Building Cable Tunnel, (manual system, closed head).

The addition of the above sprinkler systems serve to increase plant protection due to a fire. The sprinkler systems located in safety-related areas were mounted to withstand a seismic event. Dry systems were installed where water could damage safety-related equipment. There-fore, installation of this equipment does not increase the possibility of an accident.
