Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Fire Protection 3ER Clarification Gentlemen:
This letter is regarding the clarification of the Fire Protection Safety Evaluation Report related to Amendment No. 18 to the Facility Operating License for Beaver Valley Unit No.
1.
This clarification concerns the semi-annual inspection of exterior fire hydrants referred to on pages 3-3,,
4-7, and 5-20 of that report.
One of the required checks is to ensure that the hydrant barrels are dry to preclude freezing during the winter season.
However, the SER infers that this check be done in the Fall and Spring as is the case for lubrication of hydrant threads.
We wish to state that our position is that an inspection to ensure that the hydrant barrels are dry is only required in the Fall, since a check for freezing conditions in the Spring is unnecessary and a considerable amount of time and effort is required to dismount the head of the hydrant to perform this inspection.
The affected pages are attached and have been marked-up to indicate our interpretation of these requirements.
Very truly yours, 8412 Op0 4

The licensee will provide barrier guard posts to protect the

hydrants, post indicator valves and hose houses from vehicular-traffic along the east, north and west sides of the plant.
The licensee will also conduct a semiannual inspection (Fahl(fala M)

In addition to these modifications, we will require that the licensee hydrostatically test all exterior fire hose at a test pressure of 50 psi above working pressure at a maximum time schedule of once every 18 months.
.We find that, subject to the implementation of the above described
{'
modifications, the fire water piping systems satisfy the ob-jectives identified in Section 2.2 of this report and are, therefore, acceptable.
4.3.1.4 Interior Hose Stations 4
Interior hose stations are provided throughout the turbine building, service building, primary auxiliary building and the intake structure. Hose stations are not provided in the safeguards area, diesel generator cubicles, and safety-related portions of the sector cubicles, and safety-related portions of the service building.
Hose stations are equipped with 50 feet of 1-1/2 inch cotton rubber lined hose with adjustable spray nozzles. 152 ring the site visit, it was observed that several hose station valves were not tightly shut or were leaking past the seat, resulting in water accumulation in the racked hose. The licensee will administrative 1y control the condition of the hose valvas and replace seat rings where necessary to stop water from seeping into the' hose.
The licensee has performed a location analysis and hose stretch test to deter =ine which areas of the plant do not presently have. hose station coverage. Additional hose will be added to
[
existing stations (not to exceed a total of 100 feet), and additional hose stations will be installed to provide manual i
hose coverage throughout the plant as delineated in Table E.3-(
2 of the licensee's letter dated December 11, 1978.
Excess equipment will be documented and removed.

Adequacy of Fire Protection l
l The automatic water spray systems protecting the transformers i
.and the manually actuated foam system protecting the fuel oil tank are considered adequate for the hazards protected.
The barriers and distances separating safety-related equipment from potential sources of fire exposures are also considered adequate.
Although the. number and placement of the hydrants and hose houses are adequate, the equipment stored in the hose houses and the protection from vehicular danage-to the hydrants and the hose houses were found to be deficient.
5.14.6 Modifications The licensee will provide the following modifications:
1.
Hose houses and the equipment stored therein will be maintained in good condition including reasonably free of sand and dirt.
The equipment inventory in each hose house will be upgraded to include two hose gaskets for each hose size used, one 2-1/2" x 1-1/2" x l-1/2" gated Wye, and one forcible entry tool.
2.
A survey of all hydrants, hose hcuses, and post
.i indicator valves will be performed and guard posts l
installed in areas where they are subject to vehicular traffic da= age.
3.
Post indicator valves will be provided with tamper-4 proof seals and administratively controlled to insure the valves are maintained in the proper mode.
