F-C5159-3 Test Specimens Two tray 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 Generating Station. Illustrations of the penetrations tested are included in the body of the report, in Figures B-3 and B-4. Elements of Test Program A 4 ft by 4 ft concrete test slab was constructed with a fire rating of at least 3 hours. Two cable tray penetrations were constructed within the test slab in accordance with information supplied by SWEC. Cable supports were provided on the cold side of the test slab by a structure of welded 3-in angle iron. A total of 33 thermocouples (TCs) were used to monitor temperatures of the penetrations on the cold side of the slab. Placement of TCs was in accordance with the requirements of IEEE Std 634-1978 (Re f. 1) . Af ter all preparations were completed, the test slab was mounted horizontally upon the floor furnace, hot side down, and the test was initiated. The fire stop 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 3 hours. All thermo-couple readings were recorded every 15 s throughout the 3 h test. The cold side of each penetration was under direct observation throughout the test, while the hot side was observed through two small observation windows. Visual observations were made every 5 to 10 min. 6 W Mu Franidin Research Center 1-2 ao aerm r,.a.einnu.

2. IDENTIFICATION OF TEST SPECIMENS The test slab was of reinforced concrete construction with dimensions of 4 f t by 4 f t 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 two tray penetration fire stops constructed within the test slab. These penetrations were constructed to represent penetrations presently existing in the BECO Pilgrim I Nuclear Power Generating Station at Plymouth, MA. The penetrations were constructed with cables, supplied by BECO, representative of those employed in the Pilgrim I Nuclear Power Generating Station plus modifications to improve fire stop per formance. The main components used to construct the fire stops within the penetrations were: Kaowool refractory fiber, Instafoam polyurethane foam material, Flamemastic refractory coating, and Chencomp shrink-compensating grout. The cable penetrations were marked on the cold side of the test slab as Tray 1 and Trav 2. Detailed representations of the tray penetrations are presented in Figures B-3 and B-4 of Appendix B.

3. DESCRIPTION OF TEST FACILITY 3.1 TEST FURNACE The fire stop test was performed at the Fire Test Laboratory of Portland Cement Association, in Skokie, Illinois. The 4 f t 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 c
          " floor" section in a building). In operacion, 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 condicions.

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 1 ft evay from the hot surface of the test elab, 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 Temperatures produced during the fire stop test were monitored by a total of 33 chromel-alumel thermocouples placed at various positions on the cold side of the penetrations in accordance with FRC TC drawings of Ref. 3. Fig-ures B-3 and B-4 illustrate in detail the TC positions. The temperature measurements obtained were used to define the maximum cold side penetration temperatures produced and also, to define the temperature gradient existing across the penetrations.

4. TEST PREPARATIONS 4.1 TEST SLAB CONSTRUCTION The test slab was constructed of reinforced concrete, of dimensions 4 ft by 4 ft by 9 in thick. Two cable tray penetrations were constructed in accordance with SWEC instructions. Natural curing plus drying with artificial heat ensured that correct concrete strength existed prior to penetration construction.

Samples of concrete were taken and later tested to ascertain that the 2 28-day concrete strength was a minimum of 4000 lb/in . Test results in-dicated a strength of 5025 psi, thus meeting this requirement. The fire rating r2 quired for the test slab was a minimum of 3 hours. Because the fire rating of a concrete wall is a direct function 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 3-h fire rating requirement. Verification of test slab characteristics was carried out via use of the FRC Quality Assurance (QA) procedures: Materials Inspection and Documentation Requirements for Cable Penetration Fire Stop Test, (Ref. 4) and Inspection Procedure for Completed Fire Stop Test Slab and Cable Penetration Fire Stops ( Re f.5 ) . 4.2 CABLES AND CABLE SUPPORT SYSTEM 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 accor-dance with SWEC instructions to simulate existing penetration configurations in the Pilgrim I Nuclear Plant. 4M Wl:U Franklin Research Center 4-1 A Demon of The Franhan inantwe l l

F-C5159-3 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-5. The tray and cables extended 3 ft 6 in beyond the cold side of the test slab. On the hot side of the slab the tray and cables extended 12 in into the furnace. 4.3 FIRE STOP CONSTRUCTION Detailed representations of the six fire stops tested are presented in Figures BA and B-4 of Appendix B. A picture of the completed tray penetration installation is included in Figure B-2. Fcur basic components were utilized in construction of the fire stops:

1) Kaowool: a 6-lb/ft3 density ceramic fiber material placed within the penetrations in a 2-in-thick layec.
2) Instafoam #180: a polyurethane foam material foamed-in-place within the penetrations to a thickness of 6 in.
.                  3) Chencomp 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. 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.

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 cod 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 (Re f.1). The average of the three servo TC temperatures was recorded over a plot of the Ref.1 curve to give a direct visual presentation of furnace temperature variations from the specified profile for the 3-h test. A detailed log of observable events on both the cold side and the hot side of the test slab was maintained throughout the 3-h fire stop test. In tddition 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 extinquished, and the still-hot slab was lif ted from the furnace with an overhead crane. A view of the test slab in this position can be seen in l Figure B-7. The slab was then placed on its side outside the test building. 1 ( A 1-1/2-in, high pressure (75 psig, 75 gal / min) water hose was directed at the cold side of the slab from a distance of 10 f t, in accordance with the l 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-8. l l l l Oh d Franidin Research Center 5-l

6. FIRE STOP TEST RESULTS A summary of test observations and instrumentation results are presented below.

6.1 FURNACE PERFORMANCE Figure B-6 presents the furnace temperature profile obtained for the test, recorded over the IEEE Std 634-1978 temperature profile. Furnace temperature variations during the 3-h fire stop test were within IEEE Std 634-1978 requirements. 6.2 HOT SIDE TEST OBSERVATIONS Two small mica windows in the furnace wall permitted observation of the hot side of the test slab. Af ter approximately 40 min of burning, surfaces 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 on the cold side of the slab throughout the test. At I h and 10 min af ter test initiation a small amount of smoke was seen to seep through Tray Penetration #2. At I h and 47 min after test ini-tiation, Tray Penetration #2 was observed to burn through to the cold side. By the end of the test, portions of the central area of the bottom and top of Tray Penetration #2 were seen to be buckled inward approximately a maximum of 3/8 to 1/2 in due to the intense heat. Tray Penetration #1 appeared to be l totally unaffected. 6.4 THERMOCOUPLE TEMPERATURE MEASUREMENTS Cold side thermocouple temperatures for the two tray penetrations were observed to climb slowly throughout the 3-h fire stop test. At I h 40 min efter test initiation TC.16 of tray penetration #2 exceeded the 700 F tem-perature limit of IEEE Std 634-1978. Shortly thereaf ter, at I h 53 min, TC 14 W Rese MOT

F-C5159-3 exceeded the 700 F limit, followed by TC 13 at I h 55 min, TC 20 at 2 h 10 min, TC 15 at 2 h 12 min, TC 17 at 2 h 48 min, TC 12 at 2 h 48 min, and TC 11 at 2 h 57 min, all from Tray Penetration #2. No cold side TC temperatures for Tray Penetration il exceeded the 700 F limitations imposed by IEEE Std 634-1978. Table C-3 presents a tabulation of the 700 F temperature crossover points, plus end-of-test temperatures for the test (temperatures 3-h after initiation of the IEEE Std 634-1978 fire stop test). It should be noted that furnace burning was extended one recorder cycle (i.e., 3 min) beyond 3 h to ensure that all TC channels were fully represented for the test. 6.5 IEEE Std 634-1978 HOSE STREAM TEST Af ter completion of the 3-h fire test the test slab was removed from the furnace and the IEEE Std 634-1978 hose stream test was performed outside the build ing. Elapsed time between the end of the fire test and initiation of the hose strea2n test was approximately 5 min. There was no observable projection of water through the penetrations in the test slab during the hose stream test. i l l l aMf21, dd Franklin Research Center 6_2 a o, e n. rreau.
