i F-C5159-1 1 Test Specimens i 1 Six cable penetration fire stops were tested within a single concrete ) test slab. Test slab dimensions were 4 ft by 4 ft by 9 in thick. Specifications for the slab and penetrations were prepared by Stone & Webster Engineering Corporation (SWEC) in accordance with information supplied by Boston Edison Company (BECO) to represent typical penetrations existing within the Pilgrim I Nuclear Power Ge.... .ating ! Station. Illustrations of the penetrations tested are included in the i l body of the report, in Figures B-3 to B-8. ;
\
I Elements of Test Program A 4 f t by 4 f t concrete test slab was constructed with a fire rating of l at least three hours. Six penetrations were provided in total: four open-sleeve penetrations (open circular holes through the concrete slab) ] plus two penetrations consisting of 4-in galvanized steel conduits cast l l into the slab. l The six cable penetrations were constructed in accordance with drawings supplied by SWEC. Cable supports were provided on the cold side of the test slab by a structure of welded 3-in angle iron. Twenty-nine thermocouples (TC) were used to monitor temperatures of the various penetrations on the cold side of the slab. Placement of TCs was in accordance with the requirements of IEEE Std 634-1978 (Ref. 1). After all preparations were completed, the test slab was mounted horizontally upon the floor furnace, hot side down, and the test was initiated. The fire test was run in accordance with the requirements of IEEE Std 634-1978. The temperature-vs-time profile as required by IEEE Std 634-1978 was produced in the furnace for a period of three hours. All thermocouple readings were recorded every 15 seconds throughout the three-hour test. The cold side of each penetration was under direct observation throughout the test, while the hot side was obse ved through two small observation windows. Visual observations were made every 5 to 10 minutes.

i i F-C5159-1 At the end of the three-hour test, a nuclear generating station hose stream test was performed in accordance with IEEE Std 634-1978. J l Sununary of Test Results All penetrations remained physically intact throughout the fire stop test and each passed the hose stream test. One penetration exceeded the IEEE Std 634-1978 maximum temperature limit of 700 F 2 hours and 45 minutes after initiation of the test. All other penetrations remained below the 700 F maximum temperature limit, thus passing the IEEE Std 634-1978 fire stop test requirements. f I l I~ nklin Research Center c ~ ~ -..-.

- 2. IDENTIFICATION OF TEST SPECIMENS The test slab was of reinforced concrete construction with dimensions of 4 ft by 4 ft by 9 in thick, and was constructed in accordance with SWEC in-structions. Figure B-2 is a picture of the test slab just prior to the fire stop test.
The test specimens are defined as the six cable penetration fire stops j constructed within the test slab. These penetrations were constructed to I represent penetrations presently existing in the BECO Pilgrim I Nuclear Power l Cenerating '3tation at Plymouth, MA. The penetrations were constructed with cables, supplied by BECO, representative of those employed in the Pilgrim I Nuclear Power Cenerating Station. The main components used to construct the l fire stops within the penetrations were: Kaowool refractory fiber, Instafoam I polyurethane foam material, Flamemastic refractory coating, and Chescomp ahrink-compensating grout. The cable penetrations were marked on the cold side of the test slab as SLV 1 (sleeve 1) through SLV 6.

- 3. DESCRIPTION OF TEST FACILITY !
l 3.1 TEST FURNACE The fire stop test was performed at the Fire Test Laboratory of Portland C: ment Association, in Skokie, Illinois. The 4 ft by 4 ft " floor test" furnace, pictured in Figure B-1, was used for the fire stop test. This gas fired furnace produces a " standard" fire, as defined by IEEE Std 634-1978, (Ref. 1), beneath a horizontal concrete test slab (the test slab simulating a
" floor" section in a huilding). In operation, the test slab itself forms the upper surface of the furnace test volume, with an area 32 in by 32 in being exposed to the fire test conditions.
3.2 FURNACE CONTROL Three thermocouples (TC) were used to control the fire intensity to produce the required time-vs-temperature profile of Ref. 1. A tabulation of this required temperature profile is presented in Table C-1 of Appendix C. The output signals from the three control TCs were averaged together to form the temperature servo-control signal. These control TCs were located one foot away from the hot surface of the test slab, within the area of the furnace proper, in conformity with requirements of IEEE Std 634-1978. Each control TC signal was recorded on a Minneapolis Honeywell Brown Electronic temperature recorder, and the averaged servo-control signal was recorded on a Minneapolis Honeywell Brown circular chart temperature recorder. 3.3 DATA ACQUISITION SYSTEM l Temperatures produced during tha fire stop test were monitored by a total of 29 chromel-alumel thermocouples placed at various positions on the cold side of the penetrations in accordance with FRC TC drawings of Ref. 3. Three Minneapolis Horeywell Brown Electronic temperature recorders were used to ! nonitor the cold side temperatures. Figures B-3 to B-8 illustrate in detail the TC positions. In general, I three TCs were used to monitor temperatures on the cold side of each j l l l Os 3-1 dbbhanWin Research Center A Onaman af The Frennan insature l

In addition, on the majority of penetrations, one or more additional TCs were used to monitor temperature gradients along the axis of the penetration. b .m f.L Franklin Research Center 3_2 4 Omsen of The Franen insatuse

- 4. TEST PREPARATIONS 4.1 TEST SLAB CONSTRUCTION The test slab was co; structed of reinforced concrete, of dimensions 4 f t by 4 ft by 9 in thick. Four 6-in-diameter "open sleeve" penetrations (i.e.,
6-in-diameter , 's circular holes in concrete without metallic hardware) and two penetrations with 4-in galvanized steel conduits cast into the slab were constructed in accordance with SWEC instructions. Natural curing plus drying with artificial heat ensured that correct concrete strength existed prior to ptnetration construction. Samples of concrete were taken and later tested to ascertsin that the 2 28-day concrete strength was a minimum of 4000 lb/in . Test results indicated a strength of 4393 psi, meeting this requirement. The fire rating required for the test slab was a minimum of 3 hours. Because the fire rating of a concrete wall is a direct fur.ction of wall thickness, as related in the American Insurance Association Fire Resistance Ratings of Ref. 2, it was readily established that the 9-in slab thickness employed in the test more than met the three-hour fire rating requirement. Verification of test slab characteristics was carried out via use of the FRC Quality Assurance (QA) procedures: Inspection and Documentation Requirements for Materials Used in Cable Penetration Fire Stop Test, (Ref. 4) and Inspection Procedure for Completed Fire Stop Test Slab and for Completed Cable Penetration Fire Stops (Ref.5). l 4.2 CABLES AND CABLE SUPPORT SYSTEMS A tabulation of test cables used in the penetrations is presented in Table C-2. These cables were provided by BECO and were installed in recordaace with SWEC instructions to simulate existing penetration f configurations ia the Pilgrim I Nuclear Plant. I l l \ b b Franklin Research Center W..,) 4-1 s w atm vrem m e l
F-C5159-1 The cables were supported by a welded structure of 3-in angle iron bolted to the cold side of the slab, as shown in Figure B-9. Cables were supported at heights of approximately 1 ft and 3 ft 6 in from the cold face. The cable length was 3 ft 6-in beyond the cold face of the slab. On the hot side of the slab the cables extended 12 in into the furnace, except in one area where some (12 out of 38) of the cables were shortened to 11-1/2 in to 11-3/4 in to avoid interference with control thermocouple elements. 4.3 FIRE STOP CONSTPUCTION Detailed representations of the six fire stops tested are presented in Figures B-3 through B-8 of Appendix B. A picture of the completed penetration installation is included in Figure B-2. i Three basic types of penetration were constructed and tested:
- 1) One penetration utilized a single cable within a 4-in galvanized steel conduit cast into the concrete slab.
, 2) One penetration utilized 3% cable loading through a 6-in open sleeve. (Cable loading is defined as the ratio of cable 4 crossectional area to total penetration area, represented as a
! percentage.)
- 3) One penetration utilizing 40% cable loading through a 6-in, open sleeve.
Three additional penetration configurations were also tested. Each additional penetration was essentially a mirror-image of one of the above. The reversed configurations were tested because of the requirement of IEEE Std 634-1978, that non-symmetrical penetrations must also be tested in a reversed orientation and both configurations must pass the fire test in order for the i l penetration to gain qualification. Therefore, a total of six penetrations were. included in the test stab. Four basic components were utilized in construction of the fire stops: l
- 1) Kaowool: a 6-lb/ft3 density ceramic fiber material placed within l the penetrations in a 2-in-thick layer.
- 2) Instafoam #180: a polyurethanc foam material foamed-in place within the penetrations to a thickness of 6 in.
l IA adl Franklin Research Center 4-2 aom.caasn.rew nn== u.
F-C5159-1
- 3) Chemcomp Grout: a shrinkage-compensating grout hardened within the penetrations with a thickness of 1 in.
- 4) Flamemastic 77: a water-soluble refractory coating sprayed on the penetration and cables to a thickness of 1/8 in dry. This coating covered the 12 in of cables extending through the hot side of the test slab and extended to the full length of the cables on the cold side.
Figures B-3 to B-8 of Appendix B show the arrangement of fire stop components used in each of the six fire stops. Verification of fire stop characteristics was performed via use of FRC QA procedures in Ref. 5. A variation of foam density from the range specified in Ref. 5 was observed during the fire stop construction. The expected foam density range was initially stated as 1.6 to 1.9 lb/ft . In practice this is very difficult to obtain in penetrations according to the manufacturer, values up to 2.4 or 2.5 lb/ft 3being more typical in penetration work. A foam density of 2.23 lb/ft was obtained with this installation. The manufacturer indicated that the heat transfer characteristics are essentially the same throughout the density range of approximately 1.5 to 3.0 lb/ft . l i l l 1 i l I h Franklin Research Center i a cmma or n rrensen m. 4-3 ! l 1 I

- 5. FIRE STOP TEST DESCRIPTION The FRC Test Procedure for Cable Penetration Fire Stop Test (Ref. 6) was the control document for activities carried out during the fire stop test.
The test itself can be summarized as follows. Af ter all QA requirements had been met, in accordance with FRC Refs. 4 and 5, the test slab was placed in position on top of the floor furnace. The test slab in position just prior to test initiation is shown in Figure B-2. Thermocouple leads were then connected to the thermocouples mounted on the penetrations, and the furnace was ignited. The time of furnace ignition was recorded. Within the Control Lab, the furnace operators adjusted furnace draft as required to obtain optimum burning conditions. The furnace servo-controller started tracking the required temperature profile, defined beforehand by the curve of IEEE Std.634-1978 (Ref. 1). The average of the three servo TC temperatures was recorded over a plot of the Ref. I curve to give a direct visual aresentation of furnace temperature variations from the specified profile for the three hour test. A detailed log of observable events on both the cold side and the hot side of the test slab was maintained throughout the three hour fire test. In addition all test slab temperature measurements were monitored throughout the test by test personnel in the Control Lab. After the IEEE Std 634-1978 fire test was completed, the furnace was extinguished, and the still-hot slab was lifted from the furnace with an overhead crane. A view of the test slab in this position can be seen in Figure B-ll. The slab was then placed on its side outside the test building. , A 1-1/2 in high-pressure (75 psig, 75 gal / min) water hose was directed at the l cold side of the slab from a distance of 10 feet, in accordance with the requirements of IEEE Std 634-1978 for the nuclear generating station hose stream test. A picture of the hose stream test is shown in Figure B-12. l NiIbanklin Research Center _g A Connon of The Frennen enessuee I 9

- 6. FIRE STOP TEST RESULTS l
A summary of test observations and instrumentation results are presented below. 6.1 FURNACE PERFORMANCE Figure B-10 presents the furnace temperature profile obtained for the test, recorded over the IEEE Std 634-1978 temperature profile. Furnace temperatura variations during the three hour test were within IEEE Std 634-1978 requirements. 6.2 HOT SIDE TEST OBSERVATIONS Two small mica windows in the furnace wall permitted observat on of the hot side of the test slab. Af ter approximately 40 min of burning, a. rfaces of penetration components and cables, exposed to the flames began to exhibit a uniform, dull orange glow. This condition remained constant throughout the remainder of the test. 6.3 COLD SIDE TEST OBSERVATIONS Minimal activity was observed to exist on the cold side of the slab throughout the test. A small amount of smoke was seen to seep slowly through the Kaowool in SLV 6; also, a small amount of smoke was seen to slowly migrate through the cable bundle of SLV 5, emerging through the top of the bundle at the 3 ft 6 in level. At the completion of the test, observation of the cold sides of the cable penetrations indicated that none of the cable penetration fire stops had failed physically (i.e., burned through to the cold side) during the three-hour fire test. This fact was verified by the results of the hose stream test performed just af ter the fire test. 40b' Franklin Research Center a m arm r m m . 6-1
F-C5159-1 6.4 THERMOCOUPLE TEMPERATURE MEASUREMENTS Thermocouple temperatures for the cold side of the test slab were seen to I climb slowly throughout the test; however, only two TC temperatures exceeded the 700 F limit during the three hour test. As the test neared completion, TC 17, in the center of SLV 5, exceeded the 700 F limit at 2 h and 45 min after the test initiation, while the neighboring TC 18, located at the half radius point of SLV 5, exceeded the 700 F limit at 2 h and 58 min. During removal of the test slab, at the end of the test, the existence of glowing material within penetration SLV 5 avidenced the existence of the higher temperatures measured by TC 17 and 18, located within this penetration. Table C-3 presents a tabulation of the 700 F temperature crossover points, plus end-of-test temperatures for the test (temperatures three hours af ter initiation of the IEEE Std 634-1978 fire stop test). It should be not 2d that furnace burning was extended one recorder cycle (i.e., 3 minutes) beyond 3 hours to insure that all 29 TC channels were fully represented for the test.
)
6.5 IEEE Std 634-1978 HOSE STREAM TEST Af ter completion of the three-hour fire test the test slab was removed l from the furnace and the IEEE Std 634-1978 hose stream test was performed outside the building. Elapsed time between the end of the fire test and initiation of the hose stream test was appro 4mately 5 minutes. There was no observable projection of water through any of the penetrations in the test . slab during the bose stream test. l l 6-2 M" L;J klin Fran Research Center A Dmsson of The Frenamn inschare

- 7. CONCLUSIONS The results of the test can be sunmaarized by the following:
- All penetrations remained physigally intact throughout the fire test.
e All penetrations passed the required IEEE Std 634-1978 nuclear power plant hose stream test performed just af ter the fire test, o Cold side penetration temperatures remained below the 700 F maximum temperature as specified by IEEE Std 634-1978 for all penetrations except one. The one exception, SLV 5, included two TC readings above the 7000F limit. TC 17, located in the center of SLV 5 exceeded 7000F at 2 h and 45 min after test initiation. TC 18, located at the half radius point on the same penetration, exceeded 7000F at 2 h and 58 min after test initiation. 1 d0 ersnidin a..e.,ch ceni , A Chisson of the Feensen hisseuse 7_1
