-A.) SYNOPSIS:
This report ' describes a three-hour fire and subsequent hose stream
' tests (in a floor assembly) ofLTransco #TCO-001 Cement (US Cypsum L Firecode CT Gypsum Cement), #TCO-002 Medium Density Silicone, and '
1#TCO-007 Silicone Adhesive--(Dow Corning 96-081) installed in sim-ulated' electrical openings. .The test was performed in accordance with the ASTM E-119 time / temperature curve for three hours along
~
~.s with provisions.'et s forth in the ANI, NML, and IEEE-634 standards
- lfor' conducting qualification tests for penetration seals. The purpose of this-test was to demonstrate the fire resistant qual-
, ities of the overall seals when tested to the parameters of these standards. The test was conducted on November 20, 1984 at. Portland Cement Association / Construction Technology Laboratories Fire Research Laboratory (Skokie, Illinois). The-specimen consisted of 6-5" diameter (I.D.)-conduits cast in concrete into a 21" x 30" section of the 48" x 48" x 12" thick concrete-slab. .9" x.30" x 12" deep rectangular opening remained-in the 48" x 48" x :12" thick slab which was divided into 2 equal
. sections of 9" x 14 " x 12" deep each using a 1" thick Carborundum Ceramic' Hot-Board. 2-2" diameter. (I.D.) conduits with ~ bends on
.both ends were inserted into the 2-9" x 14 " x 12" deep rectangular openings ( 1 in each). All conduits contained varying amounts of electrical' cable (the'2_ rectangular openings had no cable), and all penetrations were sealed using CT Gypsum, Medium Density Silicone, or Silicone Adhesive, and US Gypsum CT Thermafiber damming.

All cables penetrated through the conduit sleeves l' on the exposed side of slab, l' through the sleeves, and 3' on the ' unexposed side of ' slab, for a total length of 5'.
.. Cables weresecured on the unexposed side of slab only using a steel frame and steel wire. The conduits in Pene. G and H were welded in place @ the unexposed side of .
slab. The cables and conduit were not secured on the exposed side of slab. Ali cable ends on the unexposed side of slab were sealed with caulking compound in compliance with IEEE-634. One conduit (Pene. E) contained a P-Line (pull rope used for cable pulls) which passed
, continuously-through the conduit out of both the fire and cold side ends of the conduit.
The outer surf ace of the flex conduits in Penetrations B and C were taped with '3M #27 Tape to seal of f most of the PVC coating on the flex conduits. This was done on the unexposed side of these penetrations only.

. TRANSCO PRODUCTS INC.- Test Report #TR-161 I Page 4 of 23 D.) SEAL' INSTALLATION: ,
U.S. Gypsum CT Thermafiber was the only damming material used for this test, and.was used and left-in-place-in all penetrations. 4" of CT Thermafiber was used in Penetration.F and the 2" conduit in Penetration H; 6" of CT Thermafiber was used in
~ Penetration A,B,C,D,E; 5" of CT Thermafiber was used in Penetrations C and H; and 2" CT Thermafiber was used in the 2" conduit in Penetration G.
^
.. The CT Thermafiber was premeasured to these dimensions and then stuffed into the penetration and 1between the cables back far enough to allow the installation of the seal material so that the seal material, when installed, would end up' flush with the top of the penetration. Damming measurements made for the 2" conduit penetrations (in .
Penetrations G and H) were made from the opening of the conduit along the back of the conduit-(the long radius of the conduit). Also, these 2" conduits did not have any straight section where the seals were-installed. ;, L The-dry #TCO-001 Cement was mixed with water in a large plastic bucket using a small electric drill motor equipped with a paddle mixer. . Material was installed by hand and using a cartridgeless caulking gun. The #TCO-002 Medium Density Silicone was hand mixed (1:1 mixing ratio by weight) in a small plastic bucket using an electric drill motor equipped with a paddle mixer, and was installed by hand. The #TCO-007 S.ilicone Adhesive, supplied in tubes, was installed using a caulking gun. When installing the seal material between cables, the-cables were moved by hand to allow the material to flow between the cables. The CT Gypsum was mixed to between a 3-1/2'i and 6-1/2" slump. CT Gypsum was installed to a fill depth of 2" in Penetrations A thru E, and Penetrations G,H, and the conduit in Penetration H had a 5" fill depth.

Test Report (ffR-161 Page 5 of 23 . D.) SEAL INSTALLATION'(cont'd): The #TCO-002 Medium Density Silicone was installed to a fill depth of 7" in the conduit in Penetration C. The #TCO-007 Silicone Adhesive was installed to a fill depth of'1" in Penetration F. All seal material was installed flush with the. top of.the penetration except in Penetration.H where the-CT Gypsum (5" thick) was installed flush with the bottom of the penetration. .All conduit ends were sealed on both the exposed and unexposed sides of the slab.
. Penetration G and H were tested to provide test data on cracks in CT Gypsum. The CT Gypsum in each penetration was cracked - 1/4" wide x 141" s wide long x full depth -
.of CT Gypsum (approximately 5" thick) to demonstrate that a 1/4" wide straight through crack (straight through to CT Thermafiber damming) could pass the 3 hour
~
' fire test and subsequent hose stream tests. Because the.5" CT Gypsum /4" CT --
- Thermafiber seal configuration is used in wall penetrations as well as floor
. penetrations, this seal configuration was tested in both directions to demonstrate a symmetrical seal (CT Gypsum flush with top of slab in Penetration G, and CT
. Gypsum flush with bottom of slab in Penetration H). ,

E.) THERMOCOUPLES: ,
~
.Thermocouples were mounted to the test specimen to gather temperature-data
.through'out the test at 5 minute-intervals for the first 2 hours and at 10 minute
- intervals for the remaining hour (per IEEE-634). Temperatures were recorded for i.
the. seal surface and seal / sleeve interface on the unexposed side of the slab for
~
F .. each-penetration. Thermocouples were'also placed at the point the continuous eon-
~
duits penetrated the unexposed side of the slab (Penes. A thru F) and where the
. . continuous conduits penetrated the unexposed side of the seal surface (Penes. G6H).
All unexposed side seal surface thermocouples were pushed slightly into the seal g surface to prevent contact with ambient air temperatures. Thermocouples used for
~
monitoring cable. temperatures on the unexposed side were mounted so that their tips were also positioned slightly below the seal surface. i-
- A thermocouple was also placed over the Is" wide crack in the CT Gypsum surface in Penetration G (@ unexposed side). This thermocouple was not in contact with any seal surface,but was positioned over thes I" crack area at slightly below the surrounding CT Gypsum surface leve'1, to monitor the air temperature coming through the crack area Another thermocouple was placed on the CT Thermafiber damming material over theareawhere.theid"widecrackintheCTGypsumexistedinPenetrationH(@un-exposed side).

'F.) FURNACE:
!The furnace used for this test measures approximately 4' X 4' at-its support ,
points.-The-furnace a'tmosphere is controlled by 4'self-igniting burners which burn natural gas and' operate in unison. The burners-are automatically controlled. i- from the control ' room.1 As the furnace atmosphere temperatures are moni-tored in the control room, automatic adjustments 'can be made to account for
~
varying amounts of fuel contribution throughout the test. The furnace atmosphere temperatures are monitored by three thermocouples..locatqc ~ 12" below the test slab. These temperatures are individually printed on a strip
~
chart and automatically averaged and compared to the ASTM E119 time / temperature curve-by computer. ~ - The furnace draf t was controlled during the test to an average pres.sure of ap-proximately nega't ive' .08" water throughout t'he test. Due to adjustments of fuel and draft during the test-(in order to follow the ASTM E119. time / temper-ature curve),-br,ief' periods of positive pressure were introduced into the fur-- nace.
.G )' TEST' RECORD:
The fire test was-conducted for 3 hours in accordance with the ASTM E119 time /
. temperature curve. Throughout the test,.an even blanket of flame _ covered the plan area of the furnace. All combustible materials located on the exposed sur -
face of the slab (ie, cable jacketing material) quickly ignited and continued
; to char for.the duration of the test.

I i Three (3) separate hose stream tests were conducted on the specimen upon conclusion of the 3 hour fire test. Water did not project from the unexposed surface of the seals during any of the 24 second long exposures, except on Penetration G, where water did pass through the premade 1/4" through crack in the CT Gypsum during the third and final hose stream test (ASTM E119 Solid Hose Stream) . Penetration G did pass the first two hose stream tests (IEEE-634 and ANI). The hose stream tests conducted were as follows: a.) IEEE-034: 75 psi hose stream delivered through a 1-1/2" hose equipped with
, a fog nozzle set at a discharge angle of 30 from a distance of 10 feet.
b.) ANI: Same as above except that the nozzle was set at a discharge angle . of 15*. c.) ASTM E119: 30 psi solid stream delivered through a 2-1/2". hose equipped with a 1-1/8" tip set on a playpipe from ~a distance of 20 feet. '. ': H.)

Re: TRANSCO PRODUCTS, INC. FIRE TEST REPORTS NOS. TR-159 AND TR-161
Dear Mr. Elias:
A fire test was conducted on November 14, 1984 on simulated electrical openings in a vall assembly, and on November 20, 1984 on simulated electrical openings in a floor assembly. The tests were conducted for the purposes of qualifying the fire barrier penetration seals in , accordance with the IEEE-634 Standard. The fire tests were witnessed by M&MPC representatives and preliminary copies of the captioned reports were reviewed in accordance with IEEE-634 Standard acceptance criteria. We find the fire tests satisfactorily _ meet the IEEE-634 test acceptance ,_ criteria, except as indicated below. A final review and comment on the - certified test reports will be provided when the reports are submitted. TEST REPORT TR-159 This test report describes a three hour fire and subsequent hose stream test for a wall assembly using Transco No. TCO-001 Cement (US Gypsum fire code CT Gypsum cement). The test slab measured 48"x 48"x12" thick.
. A total of nine, 5" diameter steel conduits were installed within the test slab. As a result of our review of this test and test report we find that penetrations A, C, E, G, H and I satisfactorily meet the acceptance criteria. Penetrations B, F and D meet the acceptance criteria to the extent that the penetration seals did not allow the passage of hot gases or flames through the barrier or the burning of cable installations on the unexposed side. Penetrations B, F and D, did not satisfactorily pass the temperature criteria for conductor temperatures on the unexposed surface.
The IEEE-634 hose stream test, ANI hose stream test and solid hose test , was conducted on all penetrations with satisfactory results. In summary, the test results show that the installation of 2"'of CT gypsum with 6" CT thermafibre is not an acceptable installation where the seal is applied at the wall. The test does show that the fire penetration seal configuration of 2" of gypsum and 6" of CT thermafibre is acceptab3e for conduit end seals, where both ends of the conduit are sealed with the same configuration. 222 South Riverside Plaza, Chicago, Illinois 60606, Telephone 312 648-6000 .,

.. M&M Protection Consultants *.A g ..
I Mr. D. Elias December 10, 1984 - Page Two TEST REPORT NO. TR-161 We find penetrations A through F acceptable throughout the . Byron , plant = in both 3-hour floor assemblies as well as 3-hour fire walls. ' These penetrations performed in ~an acceptable manner in the configurations tested.
. . . Penetrations C and H have passed the temperature criteria .on tl$e a unexposed side as well as the IEEE-634 hose stream test and the ANI hose stream test. However, when the solid stream test was performed on these seals, penetration G did project - water on the unexposed . side and penetration H experienced a slight bulging of the seal. It should not be used in an area (such as: Fuel Handling Building) where solid stream hose nozzles are present.
Penetrations C and H both contained a 2" conduit. Conduit end seals were provided in each ' penetration. Penetration G contained 7" of-silicone foam and 2" of CT thermafibre. Conduit H contained 5" of _. gypsum and 4" of CT thermafibre. Both penetration conduits contained a bend with no straight sections. The seals within the conduit were
-placed within the bend area.
We would not recommend that penetration assemblies utilized in the plant be of any other configuration that would be larger or with less sealant material than tested within these ' fire tests. In areas of the plant
~ where the configuration using 2" o f gypsum and 6" of CT thermafibre is applied at the wall, we would recommend the necessary repairs as -
tested be implemented. Acceptable repairs would be to install either an additional 4 inches of thermafibre or apply the acceptable floor penetration - seal configuration consisting of 5" of CT gypsum and 4 inches of CT thermafibre. Should you have.any further questions regarding our comments, please let . me know. Very truly yours,
. U ll)

" Crack Criteria"
Dear Mr. Elias:
As a result of our witnessing and review of the above referenced fire tests and corresponding fire test report, we recommend the existing inspection " crack criteria" for the Transco Products, Inc. fire penetra-tion seal configurations consisting of combination CT gypsum and CT thermafiber as tested, may be expanded as follows: Crack Dimensions Action To Be Taken Initial Acceptance Inspection *
- 1. Cracks less than three Uo further action -
thirty-seconds of an necessary, inch (3/32") in width.
- 2. Cracks three thirty- Seal not acceptable seconds of an inch (3/32") for initial acceptance -
or greater in width. Repair per Transco Products, Inc. fire penetration seal repair procedures. Seal Surveil. lance Criteria ** l
- 1. Cracks less than five No immediate repairs required. l thirty-seconds of an Seal is considered operable.***
inch.(5/32") in width. Seal should be placed on the surveillances or monitoring of crack to ensure crack is j periodically surveyed and l measured for expansion. !
* " Initial Acceptance Inspection" refers to the contractors' final inspection of the penetration seal prior to turnover to Station (CECO).
** Seal Surveillance Criteria refers to station's regular seal inspec-tion program per station procedure requirements.
*** Reference to " Operable Seal" indicates seal integrity has not been jeopardized and remains a functioning rated fire penetration seal as tested in the Qualification Fire test.

~^- - On March;29,-1985 a meeting was held at the Braidwood Station construc-
' tion site to. discuss the crack criteria as-previously described. In s addition.to the aforementioned criteria recommended by.M&MPC to the
' attendees,1the following briefly summarizes the meeting events.
1.~ A summary of the purpose of the meeting and brief history regarding the subject.of cracks:within_the CT gypsum material was provided-by T. Thornley (S&L), and T.'Hoff (Transco' Products, Inc.).
.Mr. H. Massin-(CECO-SNED) also provided input with respect to some _
~
of the~ history'to the crack-subject regarding the discussions for ', the LaSalle County Station with the NRC.
.It was agreed to.that within_the Transco procedures and CECO
- - . 2.-
procedures there will be no attempt _to differentiate between the previously identified--types'.of " cracks" such as hairline cracks,. surface cracks, or.through cracks. The procedures will address
" cracks" to apply-to all situations..
- 3. A discussion-regarding the applicability.of applying an acceptance criteria-limiting the length of the-crack and possibly the overall surface' area'of the crack based upon the ratio between the crack tested compared to the seal configuration dimensions was discussed.
~
It-was concluded at this time this-criteria was not be applied to the acceptance or surveillance of the penetration seals.
, , ~4. -The aforementioned acceptance criteria recommended by M&MPC would .!
be-applied to the Braidwood site only at the present time. No
-immediate ection would'be taken at the LaSalle. County Station and
* -Reference to " inoperable" seal indicates that seal no longer remains a functioning fire penetration seal as tested and requires appropriate
. repairs or replacement.-

.s Mr. D.. Elias -
April 30,.1985 Page 3 Byron Station Unit 2, with respect to the contractors' final inspections.'. It was felt that Byron Station personnel did not want to change the acceptance criteria from that which was previously applied to the Unit.1 and common areas fire penetration seals.. A decision,regarding the Byron Station'18-month surveillance pro-4 cedure criteria will be determined at a later date.
- 5. CECO-SNED will determine whether this " crack criteria" presented, with supporting fire tests, will be submitted to the NRC for their concurrence.-
- 6. During the meet'ing, Transco confirmed that with the exception of conduit end-seals, all seal configurations at the three sites will use a fire penetration seal configuration consisting of a minimum five inches (5"),of CT gypsum with four inches (4") of CT thermafiber.
- 7. Based upon M&MPC's review of the fire tests conducted and test results which successfully tested a ceal configuration with a crack (Test Report 161) the recommended crack criteria is applicable to sil areas of the plants, except where solid stream hose-nozzles are provided (i.e. . . refuel floor) with the seal installed in a .config-uration such that the CT thermafiber is installed in a direction exposed to the area in which the solid stream hose nozzles are provided.- With the exception of this situation, the " crack. criteria"
~
proposed can be applied to the referenced-fire penetration seal configurationxin all other areas. This concludes the summary of items' discussed during this meeting.- By copy of this letter, meeting attendees are requested to advise this writer if the information provided does not accurately reflect and summarize the discussions. Should you have any further questions, please do not hesitate to-contact me. Ver trul. yours, j / R. J. Smith
