Dear t'r. Kay:
.le have reviewed your submittals dated July 2, October 9 and November 13, 1979, relating to the incomplete fire protection program items for Yankee-Rowe, identified in our Safety Evaluation (SER) dated P. arch 15, 1979.
Based on our review, the status of the incomplete items is presented in.
As indicated in Enclosure I we find the water suppression syste:r for the auxiliary boiler room to be acceptable. also identifies specific items for which we need additional information.
We advised you of this need by telephone. summarizes our re-quirerents to resolve the open issues relating to specific SER, 3.1 items.
Our consultant, Brookhaven national Laboratory (ENL) has assisted us in the review.
ENL's March 24, 1980, letter with their Yankee-Rowe Fire Protection Review report are included as Enclosure 3.
You are req.ested, within 30 days from receipt of this letter, to provide the needed information indicated in Enclosure 1 and to respond regarding your intentions to.eet our requirements identified in Enclosure 2.
- incerely,

tTRLUSunt 4 SU'MRY OF REOUIREMENTS TO RESOL"E SER 3.1 ITEMS _
0F FIRE PROTECTION FROGRAM FOR Y AN KEE-RC;.i 3.1.1 Fire Detection Systems (c) Centainment 1.
h'e will require early wa-ning' fire detection capability to be provided over in-situ-and transient combustibles, 3.i.5 ' at:- Suroressien Systems j
(b) Diesel Generator Room Sorinkler Svste 1 1.
We will require the use of 1/4 turn fire protection valves for use with the reacn rods for remote actuation capability on the fire crotection valves.
(c) Hydrocen Seal Oil Unit 1.
We will require that the speciai ha:ards system be sucolied from a separate connection to the looped plant fire protection header and that appropriate isolation valves be provided to assure that a single failure will not impair both the special hazard and turbine building sprinkler system.
(d) Turbine Euildino o
fl.
In reviewing the drawings submitted by the licensee, we were not able to determine whether there was a cross c:nnection between the s:ecial ha:ards system and tne turbine building sprinkler system. Therefore, we will require that the soe:f al hazard system (column water sprays and hydrogen seal and turbine cil cooler deluge system) be isolatsd frem the turbine building sprinkler systems by rem: val of any crcss connections to the zone i sprinkler system and by providing an incependent connection :: the io: ped fire protection supply header, with adec: ate valves installed to isolate the c:enection from the :rinkler system connection.
2.
We will require that the standoi;e hose stations be su:olied from an inde:encent ::nnecticn to the looped fire protec icn supply header and valves added so that a single failure of the # ire protection system will net impair both s:rinklers and stand:ipe hose stations.
3.
We will require that tne tur:ine buildin; sorinkler systems be exoanded t: :rovide ccm:lete area protection for the area under the tur:ine uilding :perating ficer.
2-3.1.l2 Control of C: bustibles (c) Diesel Fuel Oil Line (1)
'le will require that the diesel fuel oil.line out-site the diesel generator roces -be rerouted to
- reciude exposure of the 450V switchgear and the hi;h and low pressure safety injection pumps.
(d) Diesel Generator Rooms
~
(1) We will require a one-hour rated fire retardant coating
~
in accordance with the provisions of ASTME-119 for the structural steel beams in the diesel generator rooms.
3.1.17 Gas Sucoression System (1) We will require that the detection system be of the early warning type, i.e. ionization or photoelectric. Actuation-cf the Halon System shall be either a cross-zoned or matrix pattern, but in either case no more than two detector alarms shall be required for system actuation.
