NRC Open Items from Braidwood Fire Protection
-Inspection in August 1986 4
and CECO Responses
'K-3 Sprinkler system around the hatchway at' elevation 426' in the Auxiliary Building'outside the Laundry room was not considered adequate.
Also hatchway does not have a draft curtain.
4 CECO Response - New sprinklers will'be added at the hatchway opening prior to exceeding 5% power.
Existing sprinklers _that are. approx. 10 feet above the hatchway ~will remain in place.
By telecon on 8-28-86-the NRC has agreed to furnish CECO with the appropriate NFPA' reference to use for the design.of draft curtains if needed.
K-7 Steel plates over equipment hatches in,the curved wall area of the Auxiliary Building at elev. 426' -are not sealed to prevent the. passage of hot gasses.
CECO Response'- Gaps or openings in the existing steel plates 1~
will be sealed prior to exceeding 5% power.
Plates will be caulked into place with a fire resistant type of caulk.
4
(-
K-9 Need proofoof structural steel fireproofing adequacy.
UL listing and test data.
2 i
-CECO Response - Data on our design using Pyrocrete 102 given--to I
-the NRC for.their evaluation.
The NRC by telecon on 8-28-86 3
. informed CECO that they have closed this item.
K-11 Spare conduit seals are not adequate.
The NRC needs test data' l
to substantiate our design for sealing spare conduits.
l CECO Response - Test data will be submitted to'the NRC which' will show that conduits that are capped on both ends and sealed with fire resistant material will be an acceptable 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> t
barrier.
CECO will use that. configuration in the sealing of space conduits'.
That test data will be submitted to the NRC by-i Fuel Load.
K-12 NRC questioned the adequacy of the seals in the floor of the Upper Cable Spreading Room.
CECO Response - Data _was given to the NRC concerning these seals at the time of the audit.
The NRC by telecon on 8-28-86 informed CECO that they have closed this item.

{
l 1
4 K-18 The NRC considered the sprinkler installation around the stairwell and hatchway in the Auxiliary building at elev. 364' inadequate.
CECO Response - We will add sprinklers around this stairwell and hatchway prior to exceeding 5% power.
By telecon on 8-28-86 the NRC has agreed to furnish CECO with the appropriate NFPA reference to use for the design of draft curtains if needed.
K-19.
The NRC did not consider our justification for the separation of redundant RHR pumps and coolers adequate.
The NRC feels that our repair procedures are not an adequate compensatory measure for the separation afforded the RHR pumps.
This has been identified as Appendix R deviation A.8.
CECO Response - CECO will' upgrade one of the walls between the redundant RHR pumps to a barrier of substantial fire resistant quality.
The upgrade of the wall will be complete prior to exceeding 5% power unless material procurement difficulties preclude meeting that date.
Should difficulties like that.
arise the NRC will be notified and CECO will implement compensatory measures (such as roving fire watches) to provide protection.
K-21 The NRC questioned the fire protection measures to be used for-the propane gas line used to provide gas for burners in the rad-chem labs in the Aux. Bldg.
Ceco Response - CECO will abandon this gas line and system in place by Fuel Load.
K-22 The NRC questioned the adequacy of our sprinkler systems in various areas of the Aux. and Turbine Buildings due to physical obstructions.
CECO Response - The sprinkler systems at Braidwood have been reviewed by several consultants and have been found to be acceptable.
The consultants review letters are attached.
l l
-- K-24 The NRC questioned.the adequacy of fire protection measures for the Chemical Storage rooms adjacent to the Aux. Boiler Room.
CECO Response - M&M has reviewed this chemical storage area and has concluded that due to the substantial' fire resistant construction that conforms with-NFPA 30 no further fire protection features will need to be installed above the current design.
A fire hazards analysis for the storage area is attached for your review.
1 K-25 There are no hose stations in the valve rooms in the Main Steam tunnels.
The NRC considers detectors and hand extinguishers inadequate protection.
CECO Response - CECO will provide additional hose at a hose-station which can be used for one of the valve rooms prior to
~
exceeding 5% power.
S&L has verified that adequate pressures and flow will be available for the hose station (with the added hose) to fight a fire in the valve room.
The other valve room i
can be served by a hose from an outside hose house.
Operating will revise their pre-fire plans to account for the use of the 1
i hose stations prior to exceeding 5% power.
'here are several instances throughout the plant where hose A-11 T
stations and sprinklers protecting an area are fed from a common fire main header.
This is a violation of BTP requirements.
i' CECO Response - M&M has reviewed all instances of this
-arrangement in the plant.
Compensatory measures which include j
the use of adjacent hose stations outside of the area under consideration will have to be implemented.
Some additional hose from the portable fire brigade hose cart may have to be added to hose stations used as a compensatory measure.
Pre-fire plans will be changed as necessary to account for these cases prior to exceeding 5% power.
The only exception to the above is the case in the Containment where the hose stations and the charcoal filter deluge is on the same header.
l By agreement during the telecon on 8-28-86 the NRC considers the situation in the Containment to be acceptable as is.

BRAIDWOOD STATION FIRE PROTECTION PROGRAM REVIEW AUTOMATIC FIRE PROTECTION SYSTEMS GENERAL REQUIREMENTS FOR SPRINKLER SYSTEMS
Dear Mr. Elias:
We have completed our walkdowns and reviews for the auto-matic sprinkler systems installed on the Unit 1 and common areas of the Braidwood Nuclear Station.
Enclosed is our review of the general requirements for these sprinkler systems.
This review supersedes our preliminary review on this subject dated August 5,1985.
This review outlines deficiencies which are generic in nature to all the sprinkler systems installed at Braidwood Nuclear Station, and it was felt that it would be more reasonable to deal with these separately and that the one resultion would apply to all systems as opposed to listing each deficiency and each resolution separately for every sprinkler system installed at Braidwood.
This evaluation is based on NFPA 13-1985, " Standard for the Installation of Sprinkler Systems",
completed on-site walkdowns of the systems and Viking Fire Protection Company drawings.
If you have any questions or comments concerning this review, please contact me.
Sincerely, Sh

Dear Mr. Elias:
Enclosed is our review of the fire protection system installed over the component cooling pumps located on elevation 364'-0" of the Auxiliary Building, protection area 1-JJ.
This is an automatic wet pipe sprinkler system utilizing ordinary hazard pipe sizing and spacing.
A total of 40 Viking 212*F rated sprinklers are provided for protection of the component cooling pumps and sur-rounding floor area.
It should be noted that the station is in the process of installing water spray shields for the component cooling pump motors (Braidwood AIL
- 54) with no set completion date.
This review is based on NFPA 13 - Standard for the Installation of Sprinkler Systems, Viking Fire Protection Company drawings and an on-sits walkdown of the installed system performed on December 2, 1985.
An evaluation of the hydraulic performance of the system will be com-pleted when as-built drawings of the system become available.

Dear Mr. Elias:
Enclosed is our review of the fire protection systems protecting the hatchways and central stairvell in the Auxiliary Building, protection areas 1-KK1, 1-KK3, 1-KK4 and 1-KK5.
These are hydraulically calculated wet pipe sprinkler systems designed to provide local protection to the open areas between elevations (fire zones) in the Auxiliary Building. The systems utilize Viking 212*F rated, firematic sprinklers with 5" baffles / water shields.
It should be noted that system 1-KK2 has been incorporated into the piping of system 1-KK3.
As a result P&ID drawing M-52, sheet 8 of 14 should be changed, deleting the connection from the Auxiliary Building ring header for system 1-KK2, as no connection is present.
This review is based on NFPA 13 - Standard for the Installation of Sprinkler Systems, Viking Fire Protection Company drawings and an on-site walkdown of the installed system performed on October 24, 1985.
An evaluation of the hydraulic performance of the systems will be completed when as-built drawings of the systems become available.

Dear Mr. Elias:
We have completed our review of the fire protection system installed in the Peceiving Building and Receiving Building Warehouse. Protection Area 1-Y.
This is a single wet pipe sprinkler system providing protection to these two adjoining buildings.
The Receiving Building contains general storage of Class II and Class III combustibles. This portion of the sprinkler system is installed utilizing ordinary hazard pipe sizing and spacing, i
The Receiving Building Warehouse contains storage of Class II and Class III combustibles in a double row rack storage arrangement.
The aisles between the racks are eight feet wide and the maximum neight of storage is 20 feet. This portion of the system is an hydraulically calculated, gridded sprinkler system that is designed to provide a sprinkler discharge density of 0.33 gpm/ square foot over the hydraulically most remote 3,000 square feet protected by the system.
A mezzanine level has been installed in the southeast corner of the Receiving Building Warehouse. Presently, only noncombustible bar stock is stored below the mezzanine level and installation of additional sprinkler protection below the mezzanine level is not needed at this time. However, if storage arrangements change and combustible storage is placed below the mezzanine level, additional sprinkler protection should be provided.
Thie review is based on NFPA 13 - Standard for the Installation pf_
Sprinkler Systems, NFPA 231c - Standard for Rack Storage of Materials, Viking Corporation drawings and an on-site walkdown of the installed system performed on October 22, 1985. An evaluation of the hydrau-lic performance of the system will be ccepleted when as-built drawings of the system become available.

Dear Mr. Elias:
Our reviews of the fire protection systems installed on the various elevations of the Service Building storeroom (Protection Areas 1-M, 1-L and 1-G) have been completed. These are three wet pipe sprinkler systems each providing protection to a single floor of the storeroom which are supplied by a single sprinkler riser. The systems have been designed to actuate and alarm independently.
The storeroom at elevation 401', protection area 1-M, is protected by a sprinkler system utilizing ordinary hazard pipe sizing and spacing. The adjoining paint and oil storage room is protected by the same system, however, extra hazard pipe sizing and spacing is utilized due to the amount of flammable and combustible liquids stored within the room.
Coverage per sprinkler is 79.0 square feet in the storeroom and 69.2 square feet in the paint room. Sixty-five Viking 212*F rated sprinklers of various styles are installed.
The sprinkler system installed in the storeroom at elevation 417',
protection area 1-L utilizes 48 Viking 212*F rated sprinklers to achieve of coverage per sprinkler of 77.8 square feet. The sprinkler system at elevation 433', protection area 1-G, utilizes 68 Viking 212*F rated sprinklers to provide a coverage per sprinkler of 76.2 square feet. Both systems are designed using ordinary hazard pipe sizing and spacing.

Dear Mr. Elias:
Enclosed is our review of the fire protection system installed in the Waste Treatment Building, Protection Area 2-HH.
This is a partial wet pipe sprinkler installation protecting the curbed area surrounding the 1,000-gallon waste oil tank located in the building. The system con-sists of three 212*F rated Viking upright sprinklers, two located above the tank at the ceiling and one located at the underside of the tank.
The system is designed to provide a water application density of 0.3 gpm/sq. ft.
This review was based on NFPA 13 - Standard for the Installation of Sprinkler Systems, Viking Corporation drawings and an on-site walkdown of the installed system. An evaluation of the hydraulic performance of the system will be made when as-built drawings of the system are available.
If you have any questions or comments concerning our review, please contact me.

Dear Mr. Elias:
We have begun our review of the various fire protection systems installed at the Braidwood Nuclear Station. We will be evaluating each system separately and the review of each system will be forwarded to you upon its completion, in order that any necessary changes can be made without undue delay. The evaluations are made in accordance with the appropriate NFPA Standards and are based on Viking Corporation drawings and on site walkdowns of the installed systems. The appropriate NFPA Standards used to evaluate each system will be listed at the beginning of each review.
After our evaluation of all the individual systems is complete, we will issue a review of the items which pertain to the entire plant (such as stock of spare sprinklers, etc.).
Enclosed is the review for the fire protection system installed in the Unit 1 Auxiliary Boiler Room. Area 1-BB.
This system is a wet pipe automatic sprinkler system utilizing extra hazard pipe sizing and spacing. Thirty-eight Viking 212*F rated, upright sprinklers are used, providing an area of coverage of 63.1 square feet per sprinkler. An evaluation of the hydraulic performance of the system will be made af ter all necessary changes in the piping layout are made. Additionally, since the system is installed and operational, the temporary sprinklers and piping located under the ducts in front of the boiler can and should be removed.
If you have any questions or comments concerning our review, please l
call.

Dear Mr. Elias:
We have completed our review of the fire protection system installed in the basement of the Turbine Building, elevation 369'-0" (Unit One),
protection area 1-K.
This is a hydraulically calculated wet pipe sprinkler system designed to provide a sprinkler discharge density of 0.25 spa /sq. ft. and an area of coverage per sprinkler of 69.4 sq. ft.
This review is based on NFPA 13 - Standard for the Installation of Sprinkler Systems. Viking Fire Protection Company drawings and an on-site walkdown of the installed system performed on October 14, 1985.
An evaluation of the hydraulic performance of the system will be com-plated when as-built drawings of the system become available.
If you have any questions or comments concerning our review, please contact me.
Sincerely,
\\

Mr. D. Elias Project Engineer Commonwealth Edison Company P. O. Box 767 Chicago, IL 60690 Re: Braidwood Station Fire Protection Program Review Automatic Fire Protection Systems Protection Area 1-H
Dear Mr. Elias:
In reference to my letter of August 2, 1985 regarding our review of the fire protection system installed in Protection Area 1-H the following information is being provided to clarify and resolve items number 36 and 37 of our review. This information is based upon as-built conditions at the Byron Station which we recently reviewed for applicability to conditions present at Braidwood Station.
Additional sprinklers are necessary in order to provide sufficient sprinkler coverage to the area between columns G and J and columns 11 and 15 under the two large (greater than 4 feet wide) ducts. This may be accomplished by extending the additional sprinklers required by item 36 along the length of each duct.
To summarize, additional sprinklers should be provided below the ducts between columns G and J.
These sprinklers should extend from column 11 to a position 5 feet south of column 14.
If you have any questions or if further clarification is needed, please contact me.
