Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No._DPR-66 Fire Protection Gentlemen:
As a
result of our recent Appendix R - Fire Protection audit conducted during the week of November 18, 1985, a concern was raised by the reviewers regarding our Fire Protection Safety Evaluation Report (SER) dated June 6,
1979.
Specifically, Table 3.1
" Implementation Dates for Proposed Modifications",
item 3.12 identified as
" Control of Unnecessary Combustibles" (page 3-9) lists October 31, 1980 as the due date for item 3.12.4 titled " Combustible Waste Storage".
The intent of the commitment was for implementation of control of combustibles for the waste storage area (Primary Auxiliary Building) by the October 31, 1980 due date.
Section 5.11.6
" Modifications" (page 5-16) identifies a
new building to be constructed "in the near future".
This was not intended to mean the new storage facility would be built by October 31, 1980 as interpreted by the reviewers.
An NRC followup inspection was conducted to verify licensee compliance with the implementation schedule identified in Table 3.1 of the Fire Protection SER.
The inspection report (#80-03) dated April 2,
1980 verified administrative controls had been established for ' control of combustible waste storage and closed the item in question (item 3.12).
To clarify this issue, we suggest editorial changes be made to the SER dated June 6, 1979 as noted in the enclosed pages to avoid future misunderstandings.
Very truly yours, b@MJOS

provided.
5.
Floor drains in the diesel generator rooms will be plugged.
6.
A fail safe level detecting device will.be installed in a sump close to the day tank to detect an oil accumulation due to a leak. High sump level will be annuciated in the control room.
7.
Fire barrier wall penetration between Diesel Generator rooms will be evaluated and up-graded to a 3 hr barrier.
We find that, upon Unplementation of the above described modifications, the Diesel Generator Room's fire protection satisfies the objectives identified in Section 2.2 of this report and is, therefore, acceptable.
5.11 Primary Auxiliary Buildina PAR-1 5.11.1 Safety Related Equipment Safety-related equipment required for safe shutdown is located in the Primary Auxiliary Building.
It is adjacent to the service building, cable vault building and fuel building.
5.11.2 combustible Materials The only significant source of combustibles in this building are the charcoal filters in the main exhaust filter banks, electrical cable insulation in trays and unlabeled waste.
l 5.11.3 Consequences if No Fire Suppression An unsuppressed fire in this area could result in a release of radioactive contaminated materials to the environment.

ENCLOSURE Page 4 of 4 jS 5.11.4 Fire Protection System All exterior doors to adjacent buildings have 3-hour fire rating. All interior doors to stair towers in the PA building have 1 1/2 hour fire rating.
The charcoal filter banks are provided with a water deluge spray system that is actuated automatically by heat detectors.
Manual actuation capability is also provided.
Portable CO, fire extinguishers and hose racks are provided throughout thE PA building.
5.11.5 Adequacy of Fire Protection Lack of detection could allow fire to propagate unnecessarily.
5.11.6 Modifications Appropriate fire detection and suppression coverage with coamon control room alarm will be provided upon construction of the new waste storage facility.
We find that, subject to the construction of the new building and implementation of the control of combustible waste storage in the PA building, fire protection for this area satisfies the objectives identified in Section 2.2 of this report and is, therefore, acceptable.
