Dear Mr. Schwencer:

Re:

Turkey Point Units 3

& 4 Docket Nos.

50-250

& 50-251 Fire Protection The attached information is applicable to asterisked items 3. 1.2, 3.1.6, 3, 1.7, and 3. 1. 15 in the Safety Evaluation for Amendments 45 and 37 to Operating License DPR-31 and DPR-41, respectively.

Information on items 3.1.1(4) and

3. 1. 1(5) is being developed and will be submitted by approximately December 15, 1979.

Mr. Darrell Eisenhut's letter to me dated August 17, 1979 requested that we use our best efforts to improve our schedule for completion of our fire protection modifications.

Accordingly, we request that you approve these proposed modifi-cations as soon as possible.

Your approval is needed by November 30, 1979 in ordgr to maintain our current schedule.

I Very truly yours,

~Robert E. Ubrig Vice President Advanced Systems

APPENDIX A Re:

Turkey Point Units 3

8 4 Docket Nos.

50-250 5 50-251 Fire Protection FIRE WATER SUPPLY 3.1.2

Reference:

Amendment 45/37 dated March 21, 1979 As per item 3.1.2 of referenced letter, we are transmitting herewith a

copy of Bechtel Dwgs.

5610-H-5 and H-10, which have been marked up to show a 6" connection on the discharge header of the screen wash pumps as well as a 6" connection on the fire protection system main supply header.

Both of these connections will terminate in a 6".fire hose fitting.

In the unlikely event that water from the fire protection syst: em normal supply is unavailable, a 6" hose will be used to interconnect the screen wash pumps with the fire protection system and thus provide an alternate source of fire water.

3. Drill 2" holes in existing water line for threadolets.

4. Weld in threadolet 6. Install 1 1/2" piping for main supply line to where sprinklers ~ branch off. Install 1 1/2" to '1/2.".bushings where sprinklers branch off. 7. Install 1/2" elbows and pipe to-sprinklers. 8. Connect 1 1/2" piping to existing pipe with union. 9. Flush system'ntil water runs clear. '0. Heat 3 sprinkler heads so they become activated, and install these in positjon. With the 4 KV. bus de-energized and electrical dept. present, open vent and door and gradually open post i'ndicator valve to verify. the spray does not go directly on the switch gear. If spray goes on switch gear rotate head to avoid switch gear, but still wet vent and door. Install new sprinkler heads and hydrotest new piping, at 200 psi for 2 hours per NFPA 13 Section 1-11.3.1. 12. Paint outside of new pipe with a primer such as Subox Surfa-Prep. No 100 or equivalent. Then apply a finish coat of Subox 8475-13 E;Z FLO.Fire Engine Red enamel or.equivalent:

3. Drill 2" holes in existing water line for threadolets.

4. Weld in.threadolet 5. Install '1 1/2" piping for main supply line to where sprinkler'ranch off. 6. Install 1 '1/2" to '1/2.". bushings where spr2nklers branch off. Install 1/2" elbows and pipe to sprinklers. 8. Connect 1 1/2" piping to existing pipe with union. 9. Flus'h system until water runs clear. 10. -Heat 3 sprinkler heads so they become activated, and install these in positjon. With the 4 KV. bus de-energized and electr-cal dept. present, open vent and-door and gradually open post indicator valve to verify the spray does not go directly on the switch gear. If spray goes on switch gear rotate head to avoid switch gear, but still wet vent. and door. 11. Install new sprinkler heads and hydrotest new piping, at 200 psi for 2 hours per NFPA 13 Section 1-11.3.1. 12. Paint outside of new pipe with a primer'uch as Subox Surfa>>Prep. . No 100 or equivalent. Then apply a finish coat of Subox 0475-13 ~ . 'L-Z FLO Fire Engine Red enamel or equivalent.

This PC/M includes the sketches, specifications, and procedures for the installation of 3-4" $ penetrations through the Diesel Generator Room exterior walls and doors. The penetrations have been designed with fast release covers to maintain a structural seal when not used and to provide a quick access to the interior of the Diesel Generator Room when needed. c) Purppse or Reasoa for Change ('~ny tne change is nec ssz ~, including appro-priate related references aad backgrocm or histor'ca'a=or at" on.) The penetrations .will be installed to provide an unobstructed outlet for the insertion of fire deterrent foam via an existing nozzle. Insertion of the foam will suppress any interior fire which will adversely affect the function of the Emergency Diesel Generator System. The size and locations of the penetrations are such as to maximize the effective coverage of foam directed into the interior of the building. The proposed penetrations are a fire protection comitment to the NRC.

AP 0~90 15 PAGZ 45 2/28/77 PC/8 No,+~~8~ d) Written safety evaluation (If the PC/.f will change the :acility as described in the ESAR this sect'on =ust oe completed.) (See Appendix A for suggested format.) The foam suppression penetrations have been sized and located so as not to affect the structural integrity of the doors or walls of the Emergency Diesel Generator Building. No change has been made to the building which will affect its operation or function. By inspection the proposed change to the structure does not decrease the margins of safety as defined in the basis for a Technical Specification. The probability of occurrence or the consequences of a design basis accident or malfunction of equipment important to the safety of the Plant previously evaluated in the FSAR has not been increased. There is no possibility of accident or malfunction different than those previously evaluated. Since this PC/H has not in any way affected the safety of the Plant, it can be concluded that this PC/~f does not pose any unreviewed safety questions. Signed Dated

'Penetrations are sized and located-in a manner so as to preclude signjficant stresses due to dead load, live load, seismic load, or tornado loads & missiles. Since the penetrations are composed of structural steel components, their material strength properties exceed the material strength properties of the aluminum door panels. Additionally the penetrations are covered with oversize cover plates sized to,distribute surface loads symetrically into the existing structure. Therefore the doors will satisfy or exceed the original design parameters to which the doors have been analyzed. Penetrations through the walls are located on the west face. This area is protected by a structural overhang. Due to the nature of the design and conservative assumptions, no formal calculations have been generated.
