SUBJECT:

TRIP REPORT - TRIP TO UNDERWRITERS LABORATORIES, INCORPORATED TO OBSERVE THREE HOUR FIRE TEST OF ONE AND THREE HOUR VERSAWRAP RACEWAY FIRE BARRIER SYSTEMS (TAC M82809)

During April 10 and 11,1997, i visited to Underwriters Laboratories, Incorporated (UL), )

Northbrook, Illinois, to observe a full-scale fire endurance test of 1- and 3-hour Versawrap fire barrier systems. Attachment 1 is a list of individuals that observed or participated in the test.

I interacted mostly with the individuals marked with asterisks.

Transco Products, incorporated (Transco) is developing Versawrap as a stand-alone fire barrier or as an upgrade for such existing raceway fire barriers as Thermo-Lag 330-1. In general, Versawrap barriers are installed (from the item to be protected outward) as individual layers of foil, water filled mylar tubes, fioer blankets, foil, and intumescent-coated fiberglass cloth. The numbers and arrangements of the individuel barrier components are dependent on the type of item to be protected (e.g., raceway, cable, support, etc.) and the desired fire rating. (Aliachment 1 to a memorandum of April 15,1997, from K.S. West to L.B. Marsh describes the components of a typical Versawrao barrier and their general arrangements.) Entergy Operations, incorporated, is considering installing 1- and 3-hcur Versawrap fire barriers at Arkansas Nuclear One, Unit 1, and Northern States Power is considering installing a 1-hcar Versawrap barrier at Prairia Island Nuclear Power Station.

Attachment 2 is Transco Test Procedure TR-228, "Three Hour Fire Test of One and Three Hour VERSAWRAP Raceway Fire Barrier Systems for Conduits and Cable Trays,"

L. Marsh The test specimen had been constructed and installed on the test furnace before I arrived at UL. Therefore, I did not observe fire barrier installation or thermocouple placement. The overall test specimen consisted of a steel and concrete deck from which 18 individual 1- and 3-hour test articles were suspended into UL's large floor furnace. According to Kevin Hawks, Transco, (1) Transco personnel installed the Versawrap fire barriers on the test articles in accordance with Transco instructions and procedures, (2) the test articles were instrumented in accordance with GL 86-10, S 1 (3) Transco quality control witnessed and documented test specimen construction, (4) UL quality control also independently witnessed and documented test specimen construction, (5) UL will prepare the fire test report. The test articles and the conditions which they were intended to bound are described in Attachment 2. I made pen and ink changes to Attachment 2 to reflect changes that Transco had made to the test articles after it issuod the test procedure. Attachment 3 shows the test article layout, construction details, and thermocouple locations. The test articles, which did not contain cable fill, were instrumented with 438 thermocoupies.

On the basis of my observations, it appeared that UL exposed the test specimen in accordance witn tne ASTM E-119 standard time-temperature curve for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. UL programmed its data acquisition computers to electronically record the test article thermocouple temperatures every two minutes. UL also printed the thermocouple temperatures about every five minutes. UL will use the electronically recorded temperature data to judge the fire endurance performance of the individual test articles. The printed temperatures were provided for contemporaneous information during the test. About midway through the fire exposure, Transco noticed some apparently anomalous thermocouple readings. For example, closel /-spaced thermocouples were reporting vastly different temperatures. Upon examination, Transco found + hat the insulation had melted off of some thermocouple wires that were running on top of and in direct contact with the steel test deck.

Apparently, at these points the thermocouples were measuring the temperature of the test deck rather than the temperatures of the test articles. After UL and Transco placed insulating blankets between the affected thermocouple wires and the steel test deck, the printed temperatures retumed (dropped) to what appeared to be a more normal range. Transco indicated that UL would assess the impact of this event on the overall test results in its fire test report.

Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 61 minutes, it appeared that test articles A, B, C, D, L, O, and R met the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, for a 1-hour fire rating while test articles E and Q did not. Assuming that the thermocouples were working properly and on the basis of the pnnted temperatures at the end of about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 55 minutes (the temperatures at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> were not printed), it also appeared that test articles F, G, H, and I may meet the maximem single point temperature rise acceptance criteria of GL 86-10, S 1, for a 3-hour fire rating, but test articles J, .K, M, N, and P will not.

Following the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire exposure, UL subjected the test specimen to a solid hose stream test for 2-1/2 minutes. With the exception of test article P, most of the outer layers of intumescent-coated fiberglass cloth, foil, and fiber blankets were knocked off of the bottom and side surfaces of the test article fire barriers by the force of the hose stream The barrier on test article P remained intact and may not have been hit by the hose stream. In addition.

L. Marsh with the exception of test article B, a 30-inch wide steel cable tray with a 1-hour Versawrap fire barrier, it appeared that at least the innermost layer of foil (the foil attached directly to the raceway) remained intact during the hose stream test. For test article B, the foil on the bottom surface of the tray was breached, apparently by the force of the solid hose stream.

GL 86-10, S 1, states, in part, that the fire endurance qualification test for fire barrier materials are successful if "[t]he cable tray, raceway, or component fire barrier system remained intact during the fire exposure and water hose stream test without developing any openings through which the cable tray, raceway, or component (e.g., cables) is visible. .

On April 11,1997, I observed Transco disassemble the fire barriers that remained on test articles H and P after the fire and hose stream tests. For both of these proposed 3-hour fire i barrier designs, the inner layers of foil, water filled mylar tubes, and fiber blankets remained largely intact. Many of these mylar tubes appeared to contain their original inventory of water and those that had leaked contained some water. In addition, the ordinary adhesive-backed strapping tape that was used to attach the tubes to the raceways was largely free of fire damage.

One interesting part of the test was a test of a 12-inch by 12-inch by 8-inch thick silicone foam penetration seal that was penetrated by a %-inch diameter steel conduit (test article N).

In addition to the normal fire resistant damming board, the seal assembly included an outer layer of intumescent-coated fiberglass cloth (on the fire side). According to Mr. Hawks, Transco considered this a " throw away" or research and development scoping test and did not instrument the seal assembly with thermocouples to obtain unexposed side temperatures.

After the 3-hour fire exposure and hose stream test, Transco disassembled the penetrations seal. The seal assembly was intact. About 2 to 3 inches of the silicone foam material was consumed during the fire exposure. A full 5 to 6 inches of unreacted silicone foam material remained.

UL will base its determinations on the thermal performance of the test articles on its observations during the fire endurance and hose stream tests, analyses of the electronically recorded thermocouple data, and consideration of both the maximum single point temperatures and the average unexposed side temperatures. Presumably, UL will also consider the effects of the problems with the thermocouples that were experienced during the test. Attachment 4 is UL's record of test observations.

Test Procedurc itTR-228 Revision: 2 Date: February 7,1997 Page: 3 of13 SECTION 1,0 SYNO!'51S:

Transco Fire Test #TR-228 will be a single fire test conducted in accordance with the performance requirements of NRC GL 86-10, Supplement I and the ASTM E-119 time / temperature curve. The purpose of tl.is test is to demonstrate the ability of both one and three hour VERSAWRAP raceway fire barrier systems (in the same test) to protect a variety ofraceway conditions that are representative of those commonly found in nuclear power plants.

Even though some of the barrier systems to be tested are only intended for one hour applications, they will be subjected to the full three hour fire test. In these cases, the one hour banier specimens will be considered to be successful thermally if they meet the raceway tempervure pass / fail criteria of GL 86-10 for the first hour of the i

fire test. After the conclusion of the three hour fire test, both one and three hour specimens will be subjected to a hose stream test in accordance with Section 7.0 of this procedure. Testing will be performed at Underwriters Laboratories (Northbrook, Illinois).

L The overall test specimen will consist of a metal and concrete deck from which a number of simulated conduit and

cable tray raceways will be suspended. The sizes and shapes of these raceways are intended to represent conditions that bound equivalent or less severe raceway configurations in the field. These bounding conditions to be qualified by this test are described below. The metal / concrete deck with its individual raceway specimens will be placed on top of a large floor fumace where the raceways will be subjected to the three hour fire endurance test. Immediately after the conclusion of the fire test, the deck and raceway specimens are lifted as a single unit from the furnace and l

will then be exposed to the hose stream test.

The raceway items to be tested and conditions they are intended to bound are as follows:

l ITEM: DESCRIPTION:

"A" 2" x 2" Aluminum Solid-Back Cable Trav/ Tube Track - This item is intended to bound one hour l- VERSA WRAP installed on the smallest steel and/or aluminum cable tray (using aluminum as a worst case

! condition) as well as bundled steel or aluminum conduit configurations. Since this is the smallest thermal

! mass expected for cable tray applications (and therefore the most severe), this tray is intended to bound all larger steel and aluminum raceways.. Because this is a one hour wrap, it is only required to meet the i thermal pass / fail requirements of GL 86 10 Supplement I for one hour whereas the hose stream test for l this specimen will be performed immediaJy tfler the three hour fire test. This specimen will demonstrate L both horizontal and vertical raceway sections, a bend / corner, and a "Unistrut" hanger thermal short interface. This tray will be empty except for a 48 AWG bare copper cable and thermocouples. The empty tray is used to simulate a worst case thermal mass condition for cable loading.

i "B" 30".x 4" Steel Ladder-Back Cable Trav - This item is intended to bound one hour VERSA UR4P systems installed on 30" x 4" (and all smaller sizes) of both aluminum and/9r. steel cable trays (aluminum trays l stresfrom 2"x 2" through 30"x 4" are bounded thermally by item "A" above) as well as bundled i conduits. This specimen will demonstrate both horizontal and vertical runs of raceway, a bend, and a

The test raceway assembly will be fabricated from standard %" diameter rigid steel conduit that will use condulets at each end of the specimen on the exposed side of the deck. A conduit connector will also be installed on the conduit. (No

hanger will be used in the test as hangers in the field would be wTapped in the same manner as the conduit -

l the impact of the hanger thermal short in this particular case would be considered a less se',ere condition l

as it would increase the thermal mass of the test raceway.) This conduit will be empty except for a *S l AWG bare copper wire and thermocouples installed according to Section 5.0 of this procedure.

g tested herein) in the field. (In the field, the cable is located in an aluminum tray suspended on steel pM hangers. The utility wishes to evaluate the possibility of wrapping only the cable instead of the entire tray.

Mg .

i It is felt that if the aluminum tray is not wrapped, it will melt or be consumed during a fire thus leaving the cable unsupported except at points where the tray was suspended on steel hangers.)

of Transco Products Inc.'s Quality Assurance Program and applicable procedures. All fire barrier envelope ,

installation will be witnessed by Transco Products Inc. Quality Control personnel. Material components (except for tie wire and ceramic blanket) will be identified with the responsible QC's initials as each layer is installed.

Note: This test will be performed as a " Safety Related" quality program in accordance with the latest approved revision of Transco Products Inc.'s Quality Assurance Manual (10CFR, Part 21 applies) with the exception that all materials will be provided as "Q-Class" with Certificates of Conformances.

i SECTION 5.0 THERMOCOUPLES:

A.) Fire Barrier Envelope: l 1

The fire banier envelope is considered all areas of the specimen on the exposed side of the test slab. For . l these areas, thermocouples shall be mounted to the specimen to gather temperature data for the duration of the fire test. At a minimum, temperatures shall be documented at nominal two minute intervals for the duration of the test. Thermocouple placement for the fire barrier enveloce (quantity and locations) shall

.be as specified in NRC GL 86-10 and Supplement I as follows:

". Cable Trays - The temperature rise on the unexposed surface of a fire barrier system installed on a

, cable tray shall be measured by placing the thermocouples every 152 mm (6 - inches) on the exterior surface of each tray side rails between the cable tray side rail and the fire barrier material.

. Intemal raceway temperatures shall be measured by a stranded AWG 8 bare copper conductor routed on the top of the cable tray rungs along the entire length and down the longitudinal center of the cable tray run with thermocouples installed every 152 mm (6- inches) along the length of the copper conducht.

Thermocouples shall be placed immediately adjacent to all structural members, supports, and banier penetrations. ."(1) o

". .. Conduits - The temperature rise of the unexposed surface of a fire barrier system installed on a conduit should be measured by placing thermocouples every 152 mm (6 inches) on the exterior conduit surface between the conduit and the unexposed surface of the fire barrier material. These thermocouples should be attached to the exterior conduk surface opposite of the test deck and closest to the furnace fire source. The intemal raceway temperatures should be measured 1)/ a~ stranded AWG 8 bare copper

Thermocouples should also be placed immediately adjacent to all structural members, supports, and barrier penetrations.. "(1)

Free-Cable Air Drops: Thermocouples will be installed on the stranded 8 AWG wire used for demonstrating the " free-cable ait drop" every 152 mm [6 inches] in accordance with the same requirements for monitoring mternal conduit / cable tray temperatures.

(Note:In accordance with hRC GL 86-lC, Supplement I requirements, "for the thermocouples installed on corduits, ca!,le tray side rails, and bare copper conductors, a

• 13 mm (*U2 inch) installation tolerance 'is acceptable". Hence, this tolerance shall be considered acceptablefor use in this test. The tolerance is considered to befrom the point ofindividual thermocouple placement and not compounded from one thermocouple to d e next (l.e., all thermocouples can not be 6 U2"from each other but rather must be U2"from the measured 6"[ minimum] mark on the item being monitored.)

Junction box thermocouples will be installed in accordance with the requirements of Generic Letter 86- )

10, Supplement 1. l B.) Penetration Seal: l Hermocouple placement for the unexposed penetration seal surface (test item "N") will comply with the typical requirements of ASTM E814. As an optional method for protecting thermocouple tips, the thermojunctions of each thermocouple may be embedded into the seal surface or seal surface / penetrating j member interface approximately % -%" below the seal surface (because of the nature of the seal material, this placement can be performed at any time after the installation of the seal material). For this alternate method, insulation pads for covering the thermocouple tips will not be used.

All specimen temperatures shall be monitored using thermocouples (with special limits of error equal or less than ,

1.1 *C). Thermojunctions of all specimen thermocouples shall be electrically welded. All thermocouple wire shall l be supplied with certificatione of purity, accuracy, and calibration.

Furnace atmosphere thermocouples shall be placed 12" below the fumace deck / slab as well as 12" away from representative elements of the test specimen e cordance with ASTM E 119-88 requirements (not less than nine f91 thermocouples will be used to monitor fumace atmosphere temocratures). Additional furnace atmosphere thermocouples be employed around the specimen as it protrudes into the furnace. These will be placed at the laboratories discretion to supplement data acquisition in areas where fumace atmosphere thermocouples can not be mounted to satisfy ASTM E 119 re quirements because of the specimen's configuration, et cetera.

The installation and location of each ur iguely identified thermocouple (for both the specimen and furnace) sha!!

Verification may be performed as hand written notes and shall become part of the permanent records of the test. Also, all thermocouple certifications shall also become a permanent record of the test.

' Generic Letter 86-10 and Supplement 1 SECTION '6.0 FIRE TEST:

The fire test shall be conducted in accordance with the ASTM E-119 time / temperature curve (and temperature tolerance) for a mimmum of three (3) hours. As a nummum, temperature data provided by both fumace and specimen thermocouples should be monitored and documented at nominal two (2) minute intervals. The laboratory shall verify and document visual specimen performance and occurrences (i.e., smoke, et cetera) for the duration of the test.'

It is intent of the test to demonstrate as many different raceway configurations as possible. As such, several raceway test specimens exhibit multiple features (i.e., the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> large tray demonstrates the tray wrap, a " free- air" cable and interface, a wrap-to-concrete interface, etc.). If one of these features fails thermally or during the hose stream test, it is the intent of the test to then exclude that feature from the configuration being qualified. In the case of the large tray for example, if the" free-air" cable or wrap-to-concrete interface fails for any reason, it is does not cause the tray to fail provided the rest of the tray specimen meets the acceptance criteria of Generic Letter 86-10, Supriement 1. Any failed portion of a spechnen will then not be qualified by this test. ,

SECTION 7.0 HOSE STREAM TEST:

After the conclusion of the three hour fire test, the fire barrier envelope specimen (along with the surrounding penetration seal) shall be subjected to a minimum of one of the following hose stream tests (as identified in NRC GL 80-10, Supplement 1):

(a.) "The stream applied at random to all exposed surfaces of the test specimen through a 3.8 cm ( 1-

! '"-inch) fog nozzle set at a discharge angle of 30 degrees with a nozzle pressure of 517 kPa (75 psi) and a minimum discharge of 2841pm (75gpm) with the tip of the nozzle at a maximum of 1.5 meters (5 feet) from the test specimen.

L. Marsh l with the exception of test article B, a 30-inch wide steel cable tray with a 1-hour Versawrap fire barrier, it appeared that at least the innermost layer of foil (the foil attached directly to the raceway) remained intact during the hose stream test. For test article B, the foil on the bottom surface of the tray was breached, apparently by the force of the solid hose stream.  !

GL 86-10, S 1, states, in part, that the fire endurance qualification test for fire barrier  ;

materials are successful if "[t]he cable tray, raceway, or component fire barrier system )

remained intact during the fire exposure and water hose stream test without developing any openings through which the cable tray, raceway, or component (e g., cables) is visible.

i On April 11,1997, I observed ?snsco disassemble the fire barriers that remained on test articles H and P after the fire and hose stream teste. For both of these proposed 3-hour fire  ;

barrier designs, the inner layers ofioil, water filled mylar tubes, and fiber blankets remained largely intact. Many of these mylar ^ubes appeared to contain their original inventory of water and those that had leaked contained some water. In addition, the ordinary adhesive-backed strapping tape that was used to attach the tubes to the raceways was largely free of fire )

damage.

One interesting part of the test was a test of a 12-inch by 12-inch by 8-inch thick silicone foam penetration seat that was penetrated by a %-inch diameter steel conduit (test article N). I In addition to the normal fire resistant damming board, the seal assembly included an outer i layer of intumescent-coated fiberglass cloth (on the fire side). According to Mr. Hawks, Transco considered this a " throw away" or research and development scoping test and did i not instrument the seal assembly with thermocouples to obtain unexposed side temperatures.

After the 3-hour fire exposure and hose stream test, Transco disassembled the penetrations i seal. The seal assembly was intact. About 2 to 3 inches of the silicone foam material was I consumed during the fire exposure. A full 5 to 6 inches of unreacted silicone foam material l rernained. I l

UL will base its determinations on the thermal performance of the test articles on its observations during the fire endurance and hose stream tests, analy',es of the electronically recorded thermocouple data, and consideration of both the maximurn single point l temperatures and the average unexpused side temperatures. Presumably, UL will also '

consider the effects of the problems with the thermocouples that were experienced during the test. Attachment 4 is UL's record of test observations.

SUBJECT:

TRIP REPORT - TRIP TO UNDERWRITERS LABORATORIES, INCORPORATED TO OBSERVE THREE HOUR FIRE TEST OF ONE AND THREE HOUR VERSAWRAP RACEWAY FIRE BARRIER SYSTEMS (TAC MS2809)

During April 10 and 11,1997, I visited to Underwriters Laboratories, Incorporated (UL),

Northbrook, Illinois, to observe a full-scale fire endurance test of 1- and 3-hour Versawrap fire barrier systems. Attachment 1 is a list of individuals that observed or participated in the test.

I interacted mostly with the individuals marked with asterisks.

Transco Products, incorporated (Transco) is developing Versawrap as a stand-alone fire barrier or as an upgrade for such existing raceway fire barriers as Thermo-Lag 330-1. In general, Versawrap barriers are installed (from tha item to be protected outward) as individual layers of foil,_ water filled mylar tubes, fiber blankets, foil, and intumescent-coated fiberglass cloth. The numbers and arrangements of the individual barrier components are dependent on the type of item to be protected (e.g., raceway, cable, support, etc.) and the desired fire rating. (Attachment 1 to a memorandum of April 15,1997, from K.S. West to L.B. Marsh describes the components of a typical Versawrap barrier and their general arrangements.) Entergy Operations, incorporated, is considering installing 1- and 3-hour Versawrap fire barriers at Arkansas Nuclear One, Unit 1, and Northern States Power is considering installing a 1-hour Versawrap barrier at Prairie Island Nuclear Power Station.

Attachment 2 is Transco Test Procedure TR-228, "Three Hour Fire Test of One and Three Hour VERSAWRAP Raceway Fire Barrier Systems for Conduits and Cable Trays,"

Revision 2, February 7,1997. The test was a single 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire exposure followed by a solid-stream hose stream test that was intended to demonstrate the ability of both 1- and 3-hour Versawrap fire barrier systems (in the same test) to meet the acceptance criteria of Generic Letter 86-10, Supplement 1 (GL 86-10, S 1).

L. Marsh The test specimen had been constructed and installed on the test furnace before I arrived at UL. Therefore, I did not observe fire barrier installation or thermocouple placement. The overall test specimen consisted of a steel and concrete deck from which 18 individual 1- and 3-hour test articles were suspended into UL's large floor furnace. According to Kevin Hawks, Transco, (1) Transco personnel installed the Versawrap fire barriers on the test articles in accordance with Transco instructions and procedures, (2) the test articles were instrumented in accordance with GL 86-10, S 1 (3) Transco quality control witnessed and documented test specimen construction, (4) UL quality control also independently witnessed and documented test specimen construction, (5) UL will prepare the fire test report. The test articles and the ,

conditions which they were intended to bound are described in Attachment 2. I made pen and ink changes to Attachment 2 to reflect changes that Transco had made to the test articles after it issued the test procedure. Attachment 3 shows the test article layout, construction details, and thermocouple locations. The test articles, which did not contain cable fill, were instrumented with 438 thermocouples.

On the basis of my observations, it appeared that UL exposed the test specimen in accordance with the ASTM E-119 standard time-temperature curve for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. UL programmed its data acquisition computers to electronically record the test article thermocouple temperatures every two minutes. UL also printed the thermocouple temperatures about every five minutes. UL will use the electronically recorded temperature data to judge the fire endurance performance of the ind;vidual test articles. The printed temperatures were provided for contemporaneous information during the test. About midway through the fire exposure, Transco noticed some apparently anomalous thermocouple readings. For example, closely-spaced thermocouples were reporting vastly different temperatures. Upon examination, Transco found + hat the insulation had melted off of some thermocouple wires that were running on top of and in direct contact with the steel test deck.

Apparently, at these points the thermocouples were measuring the temperature of the test deck rather than the temperatures of the test articles. After UL and Transco placed insulating blankets between the affected thermocouple wires and the steel test deck, the printed temperatures retumed (dropped) to what appeared to be a more normal range. Transco indicated that UL would assess the impact of this event on the overall test results in its fire test report.

Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 61 minutes, it appeared that test articles A, B, C, D, L, O, and R met the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, for a 1-hour fire rating while test articles E snd Q did not Assuming that the thermocouples i

were working properly and en the basis of the printed temperatures at the end of about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 55 minutes (the temperatures at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> were not printed), it also appeared that i test articles F, G, H, and I may meet the maximum single point temperature rise acceptance l criteria of GL 86-10, S 1, for a 3-hour fire rating, but test articles J, K, M, N, and P will not.

With the exception of test article P, most of the outer layers of intumescent-coated fiberglass cloth, foil, and fiber blankets were knocked off of the bottom

Test Procedure #TR-228 Revision: 2 Date: February 7,1997 Page: 3 of 13 SECTION 1.0 SYNOPSIS:

Transco Fire Test #TR 228 will be a single fire test conducted in accordance with the performance requirements of NRC GL 86-10, Supplement I and the ASTM E-119 time / temperature curve. The purpose of this test is to demonstrate the ability of both one and three hour VERSAWRAP raceway fire barrier systems (in the same test) to protect a variety of raceway conditions that are representative of those commonly found in nuclear power plants.

Even though some of the barrier systems to be tested are only intended for one hour applications, they will be subjected to the full three hour fire test. In these cases, the one hour barrier specimens will be considered to be successful thermally if they meet the raceway temper *ure pass / fail criteria of GL 86-10 for the first hour of the fire test. After the conclusion of the three hour fire test, both one and three hour specimens will be subjected to a hose stream test in accordance with Section 7.0 of this procedure. Testing will be performed at Underwriters Laboratories (Northbrook, Illinois).

The overall test specimen will consist of a metal and concrete deck from which a number of simulted conduit and cable tray raceways will be suspended. The sizes and shapes of these raceways are intended to represent conditions that bound equivalent or less severe raceway configurations in the field. These bounding conditions to be qualified by this test are described below. 'Ihe metal / concrete deck with its individual raceway specimens will be placed on top of a large Door fumace where the raceways will be subjected to the three hour fire endurance test. Immediately after the conclusion of the fire test, the deck and raceway specimens are lifted as a single unit &om the furnace and will then be exposed to the hose stream test.

The raceway items to be tested and conditions they are intended to bound are as follows:

ITEM: DESCRWrION:

"A" 2" x 2" Aluminum Solid-Back Cable Trav/ Tube Track - This item is intended to bound one hour VERS 4 WRAP installed on the smallest steel and/or aluminum cable tray (using aluminum as a worst case condition) as well as bundled steel or aluminum conduit configurations. Since this is the smallest thermal mass expected for cable tray applications (and therefore the most severe), this tray is intended to bound

. all larger steel and aluminum raceways. Because this is a one hour wrap, it is only required to meet the thermal pass / fail requirements of GL 86-10 Supplement I for one hour whereas the hose stream test for this specimen will be performed immediady after the three hour fire test. This specimen will demonstrate both horizontal and vertical raceway section , a bend / corner, and a "Unistrut" hanger thermal short interface. This tray will be empty except for a #8 AWG bare copper cable and thermocouples. The empty tray is used to simulate a worst case thermal mass condition for cable loading.

"B" 30" x 4" Steel Ladder-Back Cable Trav - This item is intended to bound one hour VERXUVRAF systems installed on 30" x 4" (and all sn. :ler sizes) of both aluminum and/or steel cable trays (aluminum trays si:esfrom 2"x 2" through 30"x !" are bounded thermally by item "A" above) as well as bundled conduits.

The tolerance is considered to befrom the point ofindwidual thermocouple placement and not compounded from one thermocouple to the next (t.e., all thermocouples can not be 61/2"from each other but rather must be U2"from the measured 6"[ minimum] mark on the item being monitored)

Junction box thermocouples vill be installed in accordance with the requirements of Generic Letter 86-10, Supplement 1.

B.) Penetration Seal:

Thermocouple placement for the unexposed penetratien seal surface (test item "h"') will comply with the typical requirements of ASTM E814. As an optional method for protecting thermocouple tips, the thermojunctions of each thermocouple may be embedded into the seal surface or seal surface / penetrating member interface approximately % -%" below the seal surface (because of the nature of the seal material, this placement can be performed at any time after the installation of the seal material). For this altemate method, insulation pads for covering the thermocouple tips will not be used.

l l

All specimen temperatures shall be monitored using thermocouples (with special limits of error equal or less than j 1.l*C) Thermojunctions of all specimen thermocouples shall be electrically welded. All thermocouple wire shall  !

be supplied with certifications of pmity, accuracy, and calibration. l l

Furnace atmosphere thermocouples shall be placed 12" below the furnace deck / slab as well as 12" away from I represer.tative elements of the test specimen c cordance with ASTM E-119-88 requirements (not less than -in-

[9] thermocoupAs will be used to monitor fumace atmosphere temperatures). Additional furnace atmosphere thermocouples be employed around the specimen as it protrudes into the fumace. These will be placed at the  ;

laboratories discretion to supplement data acquisition in areas where furnace atmosphere thermocouples :an not be mounted to satisfy ASTM E-l19 requirements because of the specimen's configuration, et cetera.

Test Procedure #TR-228 Revision: 2 Date: February 7,1997 Page: 11 of 13 be mapped and verified (measured) by Transco Products Inc. Quality Control. Verification may be performed as hand written notes and shall become part of the permanent records of the test. Also, all thermocouple certifications shall also become a permanent record of the test.

' Generic Letter 86-10 and Supplement 1 SECTION 6.0 FIRE TEST:

The fire test shall be conducted in accordance with the ASTM E-119 time / temperature curve (and temperature tolerance) for a nummum of three (3) hours. As a minimum, temperature data provided by both furnace and specimen thermocouples should be monitored and documented at nominal two (2) minute intervals. The laboratory shall verify and document visual specimen performance and occurrences (i.e., smoke, et cetera) for the duration of the test.

It is intent of the test to demonstrate as many different raceway configurations as possible. As such, several raceway test specimens exhibit multiple features (l.c., the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> large tray demonstrates the tray wTap, a " free- air" cable and interface, a wTap-to-concrete interface, etc.). If one of these features fails thermally or during the hose stream test, it is the intent of the te::t to then exclude that feature from the configuration being qualified. In the case of the large tray for example,if the " free-air" cable or wrap-to-concrete interface fails for any reason, it is does not cause the tray to fail provided the rest of the tray specimen meets the acceptance criteria of Generic Letter 86 10, Supplement 1. Any failed portion of a specimen will then not be qualified by this test. ,

SECTION 7.0 IIOSE STREAM TEST:

After the conclusion of the three hour fire test, the. fire barrier envelope specimen (along with the surrounding penetration seal) shall be subjected to a minimum of one of the following hose stream tests (as identified in NRC GL 80-10, Supplement 1):

(a.) "The stream applied at random to all exposed surfaces of the test specimen through a 3.S cm ( l-1/2-inch) fog nozzle set at a discharge angle of 30 degrees with a nozzle pressure of 517 kPa (75 psi) and a minimum discharge of 2841pm (75gpm) uith the tip of the nozzle at a maximum of 1.5 meters (5 feet) from tae test specimen- (Duration of the hose stream application - 5 minut:s for both 1-hour and 3 -hour barriers); or:

%-inch) national standard playpipe with a 2.9 cm ( l-1/8 -inch) orifice at a pressure of 207 kPa (30 psi) at a distance of 6.1 meters (20 feet) from the specimen, (Duration of the hose stream application - 1 minute for a 1-hour barrier and 2 % n01utes for a 3-hour barrier); or"2 (c.) "The stream applied at random to all exposed surfaces of the test specimen through 3.8 cm ( 1 %.

(Duration of the hose stream application - 5 minutes for both 1-hour and 3-hour barriers)."2

2. Genens Letter 8610 and Supplement 1 The responsible QC shall verify and document the type of hose stream, distance, time et cetera employed in each hose stream test.

SECTION 8.0 TEST REPORT:

The laboratory performing the test shall provide a written report which accurately describes the following rrdnimum elements of the test:

1.) Verification of specimen materials and dimensions used; 2.) Verification of fire barrier envelope materials, dimensions, and installation techniques i' (procedures) used; 3.) Verification of general furnace construction / dimensions and locations of bumer, thermocouples, et cetera; 1

4.) Verification of specimen thennocouple locations (along with copies of thermocouple matenal certifications);

5.) Verification of standards used for conducting fire test along with record of both fumace atmosphere and specimen temperature data acquired during test; 6.) , Record of furn:ce pressure during fire test; 7.) Record of visual occurrences' observations of fire and hose stream tests;

L. Marsh with the exception of test article B, a 30-inch wide steel cable tray with a 1-hour Versawrap fire barrier, it appeared that at least the innermost layer of foil (the foil attached directly to the raceway) remained intact during the hose stream test. For test article B, the foil on the bottom surface of the tray was breached, apparently oy the force of the solid hose stream.

GL 86-10, S 1, states, in part, that the fire endurance qualification test for fire barrier materials are successful if "[t]he cable tray, raceway, or component fire barrier system remained intact during the fire exposure and water hose stream test without developing any openings through which the cable tray, raceway, or component (e.g., cables) is visible.

On April 11,1997, I observed Transco disassemble the fire barriers that remained on test articles H and P after the fire and hose stream tests. For both of these proposed 3-hour fire barrier designs, the inner layers of foil, water filled mylar tubes, and fiber blankets remained largely intact. Many of these mylar tubes appeared to contain their original inventory of water and those that had leaked contained some water. In addition, the ordinary adhesive-backed strapping tape that was used to attach the tubes to the raceways was largely free of fire damage.

One interesting part of the test was a test of a 12-inch by 12-inch by 8-inch thick silicone foam penetration seiL ' hat was penetrated by a %-inch diameter steel conduit (test article N).

In addition to the normal fire resistant damming board, the seal assembly included an outer layer of intumescent-coated fiberglass cloth (on the fire side). According to Mr. Hawks, Transco considered this a " throw away" or research and development scoping test and did not instrument the seal assembly with thermocouples to obtain unexposed side temperatures.

After the 3-hour fire exposure and hose stream test, Transco disassembled the penetrations seal. The seal assembly was intact. About 2 to 3 inches of the silicone foam material was consumed during the fire exposure. A full 5 to 6 inches of unreacted silicone foam material remained.

UL will base its determinations on the thermal performance of the test articles on its observations during the fire endurance and hose stream tests, analyses of the electronically recorded thermocouple data, and consideration of both the maximum single point temperatures and the average unexposed side temperatures. Presumably, UL will also consider the effects of the problems with the thermocouples that were experienced during the test. Attachment 4 is UL's record of test observations.

SUBJECT:

TRIP REPORT - TRIP TO UNDERWRITERS LABORATORIES, INCORPORATED TO OBSERVE THREE HOUR FIRE TEST OF ONE AND THREE HOUR VERSAWRAP RACEWAY FIRE BARRIER SYSTEMS (TAC M82809)

During April 10 and 11,1997, i visited to Underwriters Laboratories, Incorporated (UL),

Northbrook, Illinois, to observe a full-scale fire endurance test of 1- and 3-hour Versawrap fire barrier systems. Attachment 1 is a list of individuals that observed or participated in the test.

I interacted mostly with the individuals marked with asterisks.

i Transco Products, incorporated (Transco) is developing Versawrap as a stand-alone fire barrier or as an upgrade for such existing raceway fire barriers as Thermo-Lag 330-1. In >

general, Versawrap barriers are installed (from t'.e item to be protected outward) as individual layers of foil, water filled mylar tubes, fiber blankets, foil, and intumescent-coated l fiberglass cloth. The numbers and arrangements of the individual barrier components are '

dependent on the type of item to be protected (e.g., raceway, cable, support, etc.) and the desired fire rating. (Attachment 1 to a memorandum of April 15,1997, from K.S. West to l L.B. Marsh describes the components of a typical Versawrap barrier and their general l arrangements.) Entergy Operations, Incorporated, is considering installing 1- and 3-hour Versawrap fire barriers at Arkansas Nuclear One, Unit 1, and Northem States Power is considering installing a 1-hour Versawrap barrier at Prairie island Nuclear Power Station.

Attachment 2 is Transco Test Procedure TR-228, "Three Hour Fire Test of One and Three Hour VERSAWRAP Raceway Fire Barrier Systems for Conduits and Cable Trays,"

i Revision 2, February 7,1997. The test was a single 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire exposure followed by a solid-stream hose stream test that was intended to demonstrate the ability of both 1- and 3-hour Versawrap fire barrier systems (in the same test) to meet the acceptance criteria of Generic Letter 86-10, Supplement 1 (GL 86-10, S 1).

l The test specimen had been constructed and installed on the test furnace before I arrived at UL. Therefore, I did not observe fire barrier installation or thermocouple placement. The overall test specimen consisted of a steel and concrete deck from which 18 individual 1- and  ;

3-hour test articles were suspended into UL's large floor furnace. According to Kevin Hawks, i Transco, (1) Transco personnel installed the Versawrap fire barriers on the test articles in 1 accordance with Transco instructions and procedures, (2) the test articles were instrumented in accordance with GL 86-10, S 1 (3) Transco quality control witnessed and documented test specimen construction, (4) UL quality control also independently witnessed and documented test specimen construction, (5) UL will prepare the fire test report. The test articles and the conditions which they were intended to bound are described in Attachment 2. I made pen and ink changes to Attachment 2 to reflect changes that Transco had made to the test ,

articles after it issued the test procedure. Attachment 3 shows the test article layout, construction details, and thermocouple locations. The test articles, which did not contain  !

cable fill, were instrumented with 438 thermocouples.

On the basis of my observations, it appeared that UL exposed the test specimen in accordance with the ASTM E-119 standard time-temperature curve for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. UL programmed its data acquisition computers to electronically record the test article thermocouple temperatures every two minutes. UL also printed the thermocouple temperatures about every five minutes. UL will use the electronically recorded temperature data to judge the fire endurance performance of the individual test articles. The printed temperatures were provided for contemporaneous information during the test. About midway through the fire exposure, Transco noticed some apparently anomalous thermocouple  ;

readings. For example, closely-spaced thermocouples were reporting vastly different temperatures. Upon examination Transco found ' hat the insulation had melted off of some th~ mocouple wires that were running on top of and in direct contact with the steel test deck.

Apparently, at these points the thermocouples were measuring the temperature of the test l deck lather than the temperatures of the test artic!es. After UL and Transco placed insulating blankets between the affected thermocouple wires and the steel test deck, the printed temperatures returned (dropped) to what appeared to be a more normal range. Transco indicated that UL would assess the impact of this event on the overall test results in its fire test report.

Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 61 minutes, it appeared that test articles A, B, C, D, L, O, and R met the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, for a 1-hour fire rating while test articles E and Q did not. Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 55 minutes (the temperatures at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> were not printed), it also appearr d that test articles F, G, H, and I may meet the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, for a 3-hour fire rating, but test articles J, K, M, N, and P will not.

Following the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire exposure, UL subjected the test specimen to a solid hose stream test for 2-1/2 minutes. With the exception of test article P, most of the outer layers of intumescent-coated fiberglass cloth, foil, and fiber blankets were knocked off of the bottom and side surfaces of the test article fire barriers by the force of the hose stream. The barrier on test article P remained intact and may not have been hit by the hose stream. In addition.

Revision: 2 Date: February 7,1997 1 Page: 3 of13 i

l SECTION 1.0 l SYNOPSIS: '

Transco Fire Test #TR-228 will be a single fire test conducted in accordance with the performance requirements of NRC GL 86-10, Supplement I and the ASTM E-119 time / temperature curve. The purpose of this test is to l demonstrate the ability of both one and three hour VERSA WRAP raceway fire barrier systems (in the same test) to protect a variety of raceway conditions that are representative of those commonly found in nuclear power plants. l Even though some of the barrier systems to be tested are only intended for one hour applications, they will be l subjected to the full three hour fire test. In these cases. the one hour barrier specimens will be considered to be  !

successful thermally if they meet the raceway tempervure pass / fail criteria of GL 86-10 for the first hour of the fire test. Alter the conclusion of the three hour fire test, both one and three hour specimens will be subjected to a -

hose stream test in accordance with Section 7.0 of this procedure. Testing will be performed at Underwriters Laboratories (Northbrook, Illinois).

The overall test specimen will consist of a metal and concrete deck from which a number of simulated conduit and l cable tray raceways will be suspended. The sizes and shapes of these raceways are intended to represent conditions that bound equivalent or less severe raceway configurations in the field. These bounding conditions to be qualified l by this test are described below. The metal / concrete deck with its individual raceway specimens will be placed on '

top of a large floor fumace where the raceways will be subjected to the three hour fire endurance test. Immediately after the t.onclusion of the fire test, the deck and raceway specimers are lifted as a single unit from the furnace and will then be exposed to the hose stream test.

The raceway items to be tested and conditions they are intended to bound are as follows:

l ITEM: DESCRIPTION:

"A" 2" x 2" Aluminum Solid Back Cable Trav/ Tube Track - This item is intended to bound one hour VERSA WRAP i'istalled on the smallest steel and/or aluminum cable tray (using aluminum as a worst case conditior!) as well as bundled steel or aluminum conduit configurations. Since this is the smallest thermal mass expected for cable tray applications (and therefore the most severe), this tray is intended to bound all larger steel and aluminum raceways. Because this is a one hour wrap, it is only required to meet the thermal pass / fail requirements of GL 86-10 Supplement I for one hour whereas the hose stream test for this specimen will be performed immedia 'y after the three hour fire test. This specimen will demonstrate both horizontal and vertical raceway sections, a bend / corner, and a "Unistrut" hanger thermal short interface. This tray will be empty except for a 68 AWG bare copper cable and thermocoupies. The emptv tray is used to simulate a worst case thermal mass condition for cable loading.

"B" 30 x 4" Steel Ladder-Back Cable Trav - This item is intended to bound one hour VERSA Elf systenu installed on 30" x 4" (and all smaller sizes) of both aluminuru and/or steel cable trays (aluminum trays si:esfrom 2"x 2" through 30"x 4" are bounded thermally by item "A " above) as well as bundled conduits. This specimen will demonstrate both herizontal and vertical runs of raceway, a bend, and a

SECTION 6.0 i FIRE TEST:

f The fire test shall be conducted in accordance with the ASTM E-119 time / temperature curve (and temperature tolerance) for a muumum of three (3) hours. As a nummum, temperature data provided by both furnace and specunen thermocouples should be monitored and documented at nominal two (2) minute intervals. The laboratory shall verify and document visual specimen performance and occurrences (i.e., smoke, et cetera) for the duration  ;

of the test. '

it is intent of the test to demonstrate as many different raceway configurations as possible. As such, several raceway test specimens exhibit multiple features (i.e., the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> large tray demonstrates the tray wTap, a " free- air" cable and interface, a wrap-to-concrete interface, etc.). If one of these features fails thermally or during the hose stream test,it is the intent of the test to then exclude that feature from the configuration being qualified. In the case of the large tray for example, if the " free-air" cable or wrap-to-concrete interface fails for any reason, it is does not i i cause the tray to fail provided the rest of the tray specimen meets the acceptance criteria of Generic Letter 86-10, Supplement 1.

L. Marsh with the exception of test article B, a 30-inch wide steel cable tray with a 1-hour Versawrap fire barrier, it appeared that at least the innermost layer of foil (the foil attached directly to the raceway) remained intact during the hose stream test. For test article B, the foil on the bottom surface of the tray was breached, apparently by the force of the solid hose stream.

GL 86-10, S 1, states, in part, that the fire endurance qualification test for fire barrier materials are successful if "[t]he cable tray, raceway, or component fire barrier system remained intact during the fire exposure and water hose stream test without developing any openings through which the cable tray, raceway, or component (e.g., cables) is visible.

On April 11,1997, I obs2rved Transco disassemble the fire barriers that remained on test articles H and P after the fire and hose stream tests. For both of these proposed 3-hour fire barrier designs, the inner layers of foil, water filled mylar tubes, and fiber blankets remained largely intact. Many of these mylar tubes appeared to contain their originalinventory of water and those that had leaked contained some water. In addition, the ordinary adhesive-backed strapping tape that was used to attach the tubes to the raceways was largely free of fire Jamage.

One interesting part of the test was a test of a 12-inch by 12-inch by 8-inch thick silicone foam penetration seal that was penetrated by a %-inch diameter steel conduit (test article N).

In addition to the normal fire resistant damming board, the seal assembly included an outer i layer of intumescent-coated fiberglass cloth (on the fire side). According to Mr. Hawks, Transco considered this a " throw away" or research and development scoping test and did not instrument the seal assembly with thermocouples to obtain unexposed side temperatures.

After the 3-hour fire exposure and hose stream test, Transco disassembled the penetrations seal. The seal assemb',, > >as intact. About 2 to 3 inches of the silicone foam material was consumed during the firn uxposure. A full 5 to 6 inches of unreacted silicone foam material remained.

UL will base its determinations on the thermal performance of the test articles on its observations during the fire endurance and hose stream tests, analyses of the electronically recorded thermocouple data, and consideration of both the maximum single point temperatures and the average unexposed side temperatures. Presumably, UL will also consider the effects of the problems with the thermocouples that were experienced during the test. Attachment 4 is UL's record of test observations.

In general, Versawrap barriers are installed (from toe item to be protected outward) as individual layers of foil, water filled mylar tubes, fiber blankets, foil, and intumescent-coated fiberglass cloth. The numbers and arrangements of the individual barrier components are dependent on the type of item to be protected (e.g., raceway, cable, support, etc.) and the desired fire rating. (Attachment 1 to a memorandum of April 15,1997, from K.S. West to L.B. Marsh describes the components of a typical Versawrap barrier and their general arrangements.)

The test specimen had been constructed and installed on the test furnace before I arrived at l UL. Therefore, I did not observe fire barrier installation or thermocouple placement. The overa': 1st specimen consisted of a steel and concrete deck from which 18 individual 1- and '

3-hout t st articles were suspended into UL's large floor furnace. According to Kevin Hawks, Transcc '1) Transco _oersonnel installed the Versawrap fire barriers on the test articles in accordan with Transco instructions and procedures, (2) the test articles were instrumented i in accordance with GL 86-10, S 1 (3) Transco quality control witnessed and documented test specimen construction, (4) UL quality control also independently witnessed and documented test specimen construction, (5) UL will prepare the fire test report. The test articles and the conditions which they were intended to bound are described in Attachment 2. I made pen and ink changes to Attachment 2 to reflect changes that Transco had made to the test articles after it issued the test procedure. Attachment 3 shows the test article layout, construction details, and thermocouple locations. The test articles, which did not contain cable fill, were instrumented with 438 thermocouples.  !

On the basis of my observations, it appeared that Lt exposed the test specimen in accordance with the' ASTM E-119 standard time-temperature curve for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. UL programmed its data acquisition computers to electronically record the test article i thermocouple temperatures every two minutes. UL also printed the thermocouple temperatures about every f;ve minutes. UL will use the electronically recorded temperature {

data to judge the fire endurance performance of the individual test articles. The printed temp 9ratures were provided for contemporaneous information during the test. About midway ,

through the fire exposure, Transco noticed some apparently anomalous thermocouple j readings. For example, closely-spaced thermocouples were reporting vastly different l temperatures. Upon examination, Transce Nne hat tl.a insulation had melted off of some '

thermocouple wires that were running on top of and in direct contact with the steel test deck.

Apparently, at these points the thermocouples were measuring the temperature of the test deck rather than the temperatures of the test articles. After UL and Transco placed insulating blankets atween the affected thermocouple wires and the steel test deck, the printed J temperatura returned (dropped) to what appeared to be a more normal range. Transco  !

indicated tha UL would assess the impact of this event on the overall test results in its fire  !

test report. l Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 61 minutes, it appeared that test articles A, B, C, D, L, O, and R met the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, l for a 1-hour fire rating while test articles E and G did not. Assuming that the thermocouples were working properly and on the basis of the printed temperatures at the end of about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and 55 minutes (the temperatures at 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> were not printed), it also appeared that test articles F, G, H, and I may meet the maximum single point temperature rise acceptance criteria of GL 86-10, S 1, for a 3-hour fire rating, but test articles J, K, M, N, and P will not.

Following the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire exposure, UL subjected tie test specimen to a solid hose stream test for 2-1/2 minutes. With the exception of test articie P, most of the outer layers of intumescent-coated fiberglass cloth, foil, and fiber blankats were knocked off of the bottom and side surfaces of the test article fire barriers by the force of the hose stream. The barrier 2

on test article P remained intact and may not have been hit by the hose stream. In addition.

Test Procedure #TR-228 Revision: 2 l Date: February 7,1997 i Page: 3 of13 l

SECTION 1.0 l SYNOPSIS i

Transco Fire Test #TR-228 will be a single fire test conducted in accordance with the performance requirements of NRC C 36-10, Supplement I and the ASTM E-119 time / temperature curve. The purpose of this test is to i demonsw the ability of both one and three hour VERSA WRAP raceway fire barrier systems (in the same test) to protect a variety of raceway conditions that are representative of those commonly found in nuclear power plants.

Even though some of the barrier systems to be tested are only intended for one hour applications, they will be I subjected to the :all three hour fire test. In these cases, the one hour barrier specimens will be considered to be successful thermally if they meet the raceway tempereu:- pass / fail ; riteria of GL 86-10 for the first hour of the fire test. After the conclusion of the three hour fire test, both one and three hour specimens will be subjected to a hose stream test in accordance with Section 7.0 of this procedure. Testing will be performed at Underwriters Laboratories (Northbrook, Illinois).

The overall test specimen will consist of a metal and concrete deck from which a number of simulated conduit and cable tray raceways will be suspended. The sizes and shapes of these raceways are intended to represent conditions that bound equivalent or less severe raceway configurations in the field. These bounding conditions to be qualified ,

by this test are described below. The metal / concrete deck with its individual raceway specimens will be placed on '

top of a large floor fumace where the raceways wm be subjected to the three hour fire endurance test. Immediately after the conclusion of the fire test, the deck and raceway specimens are lifted as a single unit from the fumace and will then be exposed to the hose stream test.

l The raceway items to be tested and conditions they are intended to bound are as follows:

ITEM: DESCRIPTION:

"A" 2" x 2" Aluminum Solid-Back Cable Trav/ Tube Track - This item is intended to bound one hour VERSA HRAP installed on the smallest steel and/or aluminum cable tray (using aluminum as a worst case condition) as well as bundled steel or aluminum conduit configurations. Since this is the smallest thermal mass expected for cable tray applications (and therefore the most severe), this tray is intended to bound all larger steel and aluminum raceways. Because this is a one hour wrap, it is only required to meet the thermal pass / fail requirements of GL 86-10 Supplement I for one hour whereas the hose stream test for this specimen will be performed imm,:diady after the three hour fire test. This specimen will demonstrate both horizontal and vertical raceway sections, a bend / corner, and a "Unistrut" hanger thermal short iriterface. This tray will be empty excep.for a #8 AWG bare copper :able and thermocouples. The empty tray is used to simulate a worst case thermal mass condition for cable loading.

. "B" 30" x 4" Steel Ladder-Back Cable Trav - This item is intended to bound one hour VERSA HRAP systems installed on 30" x 4" (and all smaller sizes) of both aluminum and/or steel cable trays (alumim<m trays si:csfrom 2"x 2" through 30"x 4" are bounciect thermally by item "A " above) as well as bundled contits. This specimen will demonstrate both hcrizontal and 3ertical runs of raceway, a bend, and a

Test Procedure #TR-228 Revision: 2 Date: February 7,1997 Page: 4 of 13 "Unistrut" hanger thermal short interface. This tray will be empty except for a single #8 AWG bare copper uire and thermocouples. The empty tray is used to simulate a worst case thermal mass condition for cable loading. The use of this large steel tray is also intended to bound aluminum raceways up to this size for hose stream test qualifications of VERSABRAP. This specimen will also demonstrate a " free-cable airdrop" and its connection to the raceway wrap.

"C" %" Diameter Ricid Steel Conduit - This item is intended to bound one hour VERSAHRAP systems installed on the smallest size of conduit found in the field (the most severe thermal mass). The test raceway assembly will be fabricated fran standard L " !ameter rigid steel conduit and will utilize a "U"-

shape to represent both vertical and horizontal raceway mns. One corner of the "U"-shape will consist of a standard steel condulet and couplers while the opposite corner will be used to show the wrap installed on a small radius bend.

' Generic Letter 86-10 and Supplement 1 SECT _ ION 6.0 FIRE TESTi i

The fire test shall be conducted in accordance with the ASTM E-119 time / temperature curve (and temperature tolerance) for a nummum of three (3) hours. As a minimum, temperature data provided by both fumace and specimen thermocouples should be monitored and documented at nominal two (2) minute intervals. The laboratory shall verify and document visual specimen performance and occurrences (i.e., smoke, et cetera) for the duration of the test.

It is intent of the test to demonstrate as many different raceway configurations as possible. As such, several raceway test specimens exhibit multiple features (f.e., the 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> large tray demonstrates the tray wrap, a " free- air" cable and interface, a wTap-to-concrete interface, etc.). If one of these features fails thermally or during the hose stream test, it is the intent of the test to then exclude that feature from the configuration being qualified. In the case of the large tray for example, if the " free-air" cable or wrap-to-concrete interface fails for any reason, it is does not cause the tray to fail provided the rest of the tray specimen meets the acceptance criteria of Generic Letter 86-10, Supplement 1. Any failed portion of a specimen will then not be qualified by this test.

l SECTION 7.0 HOSE STREAM TEST:

1 After the conclusion of the three hour fire test, the fire barrier envelope specimen (along with the surrounding  !

penetration seal) shall be subjected to a muumum of one of the following hose stream tests (as identified in NRC l GL 80-10, Supplement 1): )
