Dear Mr. Denton:

EVALUATION REPORT
,I.JUU, Utaf\\[j Fil£ co*
SURRY POWER STATION f'f VEPCO letter serial No. 354B/061478 agreed to implement fire protection modi-fications based on the first draft of the Safety Evaluation Report for Surry 1
& 2.
The purpose of this letter is to submit target dates keyed to a second draft fire protection Safety Evaluation Report fot Surry Units 1 and 2.
The target dates as shown in attachment (1) are realistic schedule dates that will be used to complete the modifications in an orderly fashion.
We commit to implementing all modifications listed in attachment (1) by October 1980 except as noted.
The below listed modifications will be implemented by the end of the next Unit 2 refueling outage following the present steam generator replacement outage.
This refueling is tentatively scheduled to begin March, 1981.
3.1.5 Safe Shutdown Circuitry Unit 2 3.1.9 3.1.15 The design will be complete by October 1980 however an outage of approximately 2 weeks is required to install the modified circuitry.
If an outage of the required length occurs prior to the next Unit 2 refueling, the modification will be installed, however the modi-fication is being scheduled for the next Unit 2 refueling.
Fire Detection Systems The fire detection modification requires smoke detector installa-tion in almost all areas of the station.
Locating the detectors and designing and installing the electrical panels and wiring is a l/\\
large task and will require the schedule indicated.

VIRGINIA ELECTRIC AND POWER COMPANY TO Mr. Harold R. Denton, Director tion system will be complete by October 1980, however the refuel-ing outage is required for final fit up of the collecting cans and the containment equipment hatch must be opened to install the oil storage tank.
3.1.23 Monitoring Panels Design of the Fuel Building Monitoring Panels will be complete by August 1980.
However, the Unit 2 refueling outage is required to install the monitoring panels and reactor coolant monitoring in-strumentation.
3.1.25 Safe Shutdown Charging Pump Cross - Connect The charging pump cross connect requires an in depth evaluation and analysis of the implications involved in the cross connect.
Approval of the NSSS Vendor is also required.
The Unit 2 refuel-ing is required to complete the modification.
3.2.5 In-situ Testing In-situ Testing of the smoke detectors cannot be completed until the smoke detector installation is complete.
The above modifications require either extensive engineering and analysis or an extended outage for installation.
Every effort will be made to complete installation and testing prior to the target dates.
However, these dates al-ready reflect an optimistic schedule.
