Dear Mr. Kubicki:
All entries and exits of test articles, utilized in the above subject test j
programs, were sealed sir tight with THERMO-LAG 330-70 conformabic Ceramic j
Blanket in order to prevent air from circulating within each test article.
All test articles were instrumented with chrome 1/alumel thermocouples., The thermocouples were uniformly distributed within each test article. They were placed on the surface of the cable jacket at approximately twelve inch (12") intervals, in most instances, in the immediate proximity of the metal i
enclosure comprising the shelf, ladder rungs, or wall of the tray or, in the case of the conduit, its walls and on the surface of the bottom or side row of the cables being tested. The primary objective of these engineering thermocouples was to identify and characterize the " worst case" - or the f.c.

SUMMARY
1.1 Introduction i
i This report presents and discusses the experimental test results obtained from performing one-hour ASTM E119 fire endurance tests, followed by water hose stream tests, on test assemblies protected with a one-hour fire rated design of the THERMO-LAG 330-1 Sub11 ming Coating Envelope System.
The test assemblies consisted of various arrangements of generic power, control and instrumentation cabling in a ladder and solid bottom cable tray and conduit, as well as pullbox, a condulet and air drop. A protective I
envelope repair procedure was also tested.
This test program was conducted in accordance with all applicable sections of TSI's Engineering Test Plan, second revision dated March 8, 1982, and as supplemented by Minutes of the Meeting dated 2 June 1982 and TSI's letters to ANI dated August 2 and September 3,1982. This test plan and i
supplements thereto were reviewed and approved by the American Nuclear Insurers prior to the commencement of the test program as indicated by letters dated March 16 and August 6, 1982.
All of the materials comprising the TRERMD-LAG 330-1 Subliming Coating Envelope System used in this test program were manufactured in accordance with the procedures set forth in TSI's Nuclear Quality Assurance Program Manual and Quality Control Operating Procedures Manual, which were also previously accepted by the American Nuclear Insurers.
The THERMO-LAG 330-1 Subliming Coating Envelope System materials were applied in accordance with the procedures set forth in TSI's Nuclear Quality Assurance Program Manual and Quality Control Operating Procedures Manual. The envelope and the configuration is described in Section 7.0 and 8.0 of this report, Product Applicatica and Repair Procedures are shown in Section 4 of Appendix I to this report.

1.2 Sunanary Based on the results and observations of this test program, the THER)O-LAG 330-1 Subliming Coating Envelope System usets all the requirements and performance criteria of AN1's Bulletin #5(79) entitled: "AN1/MAERP Standard Fire Endurance Test Method to Qualify A Protective Envelope For Class 1E Electrical Circsits", which is shown in Appendix II of this report. This conclusion is supported by the following test results and observations.
1.
The test articles were exposed to the standard time /tempe,rature curve of ASTM E119 for a minimum of one hour, followed by a 24 minute, minimum, water hose stream test, with no loss of circuit integrity in the test circuits. The THERic-LAG 330-1 Sub11 ming Coating Envelope System met all the one-hour ASTM E119 fire endurance and water hose stream test j
requirements in all aspects.
2.
The water hose stress test did not adversely affect the virgin THERMO-LAG 330-1 Sub11 ming Coating Envelope System remaining on the test articles following the fire endurance test.
l 3.
Examination of the cables within the test articles, following both the fire endurance and water home stress tests, indicated that they were all intact, functional and free of heat or fire damags.
4.
The recorded cable surface temperatures in all test articles after ex9osure to the ASTM E119 time /temperatura environment for a minimum of 60 minutes never exceeded:
A) Average - 210'F B) Maximum Singular Thermocouple - 288'F l

i 2.0 PURPOSE 3-The purpose of this test program was to provide engineering information required to qualify the THERM 0-1.AG 330-1 Subliming Coating Envelope System for use as a one-hour protective fire rated barrier for cable trays, conduits, air drops instrumentation and equipment which contain " generic" cables.
This test program was performed to verify the capability of THEIUC-LAG 330-1 Sub11 ming Coating Envelope System to meet all the applicable acceptance i
criteria specified by the American Nuclear Insurers in their Bulletin #5(79),
f 3.0 TEST LOCATION The test were performed during the period of September 9 through September 28 1982. The tests were conducted at the laboratory facilities of TSI. Inc. in St. Louis Missouri by its personnel, and under the supervision and total control of Industrial Testing Laboratories of St. Louis Kissouri, an independent testing laboratory, i

4.1 ASTM E119 Fire Endurance Tests Paragraph 3.4.1 of ANI's Bulletin #5(79) states that the protective envelope shall be exposed to the standard time / temperature curve found in ASTM E119-76 (revised to E119-81) for a minimum of one hour. In this test, test articles were exposed to the standard time / temperature curve presented in ASTM E119-76 (ANSI A2.1) for a minimum period of one (1) hour. The standard time / temperature curve is presented herein as Figure 1.
i The required accuracy of the temperature control requirement under this test program is that the area under the test time / temperature curve shall be within ten percent (10%) of the corresponding area under the standard time / temperature j
curve.
4.2 Water Hose Stream Tests In accordance with Paragraph 3.4.2(1) of'ANI's Bulletin #5(79). sach of the test articles was exposed to a 2k minute minimum water hose stream test, applied to the exposed surfaces of the test articles, within three (3) minutes after the completion of the fire endurance test.
A Mack 800 gpa water pumper fire truck was used to provide the water hose stream during these tests. The hose stream was delivered through a 2h-inch national standard playpipe, equipped with a 1 1/8-inch tip at a nozzle i
pressure of 30 pai. The tip of the nozzle was held at a distance of 20 feet from the test assembly. The length of the hose was 50 feet.
4.3 Electrical Circuit Integrity Monitoring Paragraph 3.5 of ANI's Bulletin #5(79) requires that circuits contained in a test article do not de-energize during exposure to the fire sndurance and water j
hose stresa tests. A required test condition is to conti,nuously monitor a sufficent" number of electrical circuits in each test specimen to detect failure; circuit to circuit (conductor to conductor short circuits), circuit to system (conductor continuity), and circuit to ground (conductor to ground).
Schematic diagrams of the three monitoring channels utilitized in this test program are shown in Figure 2.

Since monitoring all of the conditions in each test assembly wuld be impractical, eight cables in each of the test assemblies were to be continuously monitored during the fire endurance and water hose strean tests using both a kiti-light Display Fanal and an Eight-Channel Event Recorder as follows: (Specific cables instrumented in each of these monitoring channela are shown in Table 1) 1.
Power, control and/or instrumentation cables la each assembly wars connected as a short circuit detection circuit as shown in Figure 2Ag 2.
Power, control and/or $4strumentation cables in sich assembly were connected as a contimulgy monitoring cir,cuit as shown in Figure 2B; 3.
Power. control and/or instrumentation cables in each assembly were connected as a ground detection circuit as shown in Figure 2C.
The cables selected for continuous monitoring were immediately adjacent to a wall or to ladder runge of the assembly to insure that the most heat critical locations were being monitored.
The hiti-light Dispisy Pagel and Event Recorder were wired in such a i
manner that the monitored ctreuits were energized, and in'the event of a e
test article cable failures.

11.0 TEST OBSERVATIONS 1 i A. Details of the One-Hour ASTM E119 Fire Endurance Teste j f The total exposure to the ASTM E119 time / temperature environment i for each of the one-hour fire endurance tests was as follows: TEST NLHBER TIME IN MINUTES 61 1 65 2 61 3&5 Combined 60 4 61 6 Electrical cable surface temperature asasurements were recorded once every six (6) minutes (5 seconds between individual thermocouple readings) using the 24 Point Chart Type Thermocouple Temperature Recorder. I B. Visual Observations Made During the Fire Tests 1. Only light volatiles were observed to come from within the test articles at any time during the one-hour fire exposure period. 2. After a period of approximately 50 minutes into the fire exposure, a " slight" cracking was observed to have occurred in the outer layer of the THERMD-LAC 330-1 Subliming Coating as it begins to expand and form the char layer. 3. During the remainder of the fire endurance tests, the subliming coating continued to expand and form progressively greater char areas. 4. Photographs of the test articles after being exposed to the one-hour ASTM E119 fire endurance tests and the water hose stream tests are shown in Figures 15A through 15E. j 5. Examination of the test articles after exposure to the fire endurance and water hose stream tests showed evidence that a considerable amount of virgin material (white areas) were present. The " dark areas" shown in Figures 15A through 15E represent the char formation of the consumed product. ( 48
I 6. Af ter the fire arposure, evamination of the edges, butt joints. flanges and simulated repair patched area, which had been applied with the THERMO-LAG 330-1/ Cure Accelerator mixture. indicated that i this material mixture will provide the same degree of fire i resistive enhancement as the THER)C-LAG 330-1 Subliming Coating when the Cure Accelerator has not been added. C. Details of the Water Hose Stream Tests As required by Paragraph 3.4.2(1) of ANI's Bulletin #5(79), water hose stream tests were conducted following each of the fire endursace The time span between removal of the test article from the tests. furnace and the start of the water hose stream test. in all cases, was within three (3) minutes. The following test conditions were used: 1. A Mack 800 gpa water pumper fire truck was used for conducting the required water hose stream tests. 2. A 2 -inch diameter national standard playpipe equipped with a 1 1/8-inch tip was used to conduct the water hose stream tests. 3. The nozzle discharge pressure ranged between 30 and 45 psi which meets or exceeds the minimum of 30 poi required in AN1's Bulletin f5(79) for water hose stream tests. 4. The nozzle distance from the test article was maintained l at a maximum of 20 feet. 5. The length of the water hose was 50 feet. 49 i

D. Visual Observa: ions Made During the Water Rose Stream Tests 1. The duration of the water' hose stress tests ranged between 2\\ and 3h minutes for each test article, as compared to ANI's water hose stream exposure requirement of 2 minutes, minimum. 2. The virgin phase of the THERMO-MG 330-1 Subliaing Coating Envelope System remaining af ter the ASTM E119 fire endurance tests did not separate from the test articles during the water ~ hose stream tests. 3. Examination of the cables after the completion of the tests, as shown in Figures 16A throush 16E indicated that none of the ') electrical insulation of the cables were damaged. Further j examination of the nylon tie wires used in retaining the cables within each test article showed no evidence of damage. 1 4. The " repair" patch on Test Article No. 3&S Combined showed no evidence of damage after the fire exposure and water hose stream tests. This indicates that the THERM 0-MG 330-1 Subliming Coating Envelope System will provide the same degree of fire resistance with no adverse effects to a repaired area when compared to an unrepaired area. 5. Examination of all joints and surface areas where the THERMO-LAG 330-1/ Cure Accelerator sixture was used shoved no distinguishable difference in appearance after exposure to both the fire endurance and water hose stream tests. l 55 a
E. Details of the Electrical Circuit Integrity Nonitoring As required by Paragraph 3.5 of ANI's Bulletin #5(79). a sufficient number of electrical circuits were monitored in each test article throughout the ASTM E119 fire endurance and subsequent water hoss' stream tests to datect failure on a circuit to circuit circuit to system and circuit to ground basis. All electric cables which were selected for electrical circuit integrity monitoring were located in thermally critical areas immediately adjacent to the walls or steel rungs of the test article. l F. Visual Observations Made During the Electrical Circuit Integrity Monitorica 1. An Eight (8) Channel Event Recorder and a Multi-light Display Panel were used in parallel to conduct the electrical circuit integrity monitoring. 2. Power, control and/or instrumentation cables in the test I circuit of each test assembly were connected as a short circuit detection circuit. No failures were observed during either the fire endurance or water hose straan tests. 4 3. Power control and/or instrumentation cables in the test circuit of each test assembly were connected as a continuity j monitoring circuit. No failures were observed during either the fire endurance or water hose streas tests. 4. Power, control and/cr instrumentation cables in the test circuit of each test assembly were connected as a ground short circuit detection circuit. No failures were observed during either the fire endurance or water hose stream tests. Specific cables in each of the test articles, instrumented for monitoring the cable integrity during the fire endurance and water hose strema tests, are shown in Table 1, with the original test data presented in Appendix IV. 56 (

A comparison of the ASTM E119 test method time / temperature curve with the actual range of temperatures obtained during each test is shown in Figures 22 through 26. For each comparison, the area under the test time / temperature was calculated by integrating the time / temperature intervals under the curve. All integrated test areas were within 90% and 100% of the integrated standard area. i l 1 6. Throughout the fire endurance and water hose stream tests, the Multi-light Display Panel remained in its prescribed lighted and non-lighted positions. The lights were energized in the l circuit to system monitoring system, while the lights in the circuit to ground / circuit to circuit monitoring system were not. 9. The Eight (8) Channel Event Recorder also indicated no circuit failures or faults during any of the fire endurance and water hose stream tests. s 10. This indicates that the test articles containing generic cables, protected with the one-hour fire rated design of the IEERMO-LAG 330-1 Subliming Coating Envelope System, meets all of the prerequisites specified for electrical cable integrity in the ANI/MAERP Standards. 63 l i

13.0 CONCLUSION
S Based on the test results as well as detailed visual inspection of each test article before and af ter the one-hour ASTM E119 fire endurance test and the water hose stream test, it can be concluded that: The THEILSIO-LAG 330-1 Sub11 ming Coating Envelope System meets the requirements as specified in Paragraph 3. 4.1, 3.4. 2 (1), and 3.5 of ANI's Bulletin f5(79) entitled: "ANI/MAERP Standard Fire Endurance Test Method To Qualify A Protective Envelope For Class 1E Electrical Circuits", when applied to cable trays, conduit, air drops, instrumentation and equipment containing " generic" cables. This conclusion is supported by the following test results and observations: 1. All test articles were exposed to the standard time /tesperature environment of ASTM E119 for a minimum of one (1) hour, followed by a 215 minute minimum water hose test as required by ANI's Bulletin #5(79). The THERMO-LAG 330-1 Subliming Coating Envelope System successfully met ( these test requirements in all aspects. 2. There was no loss of circuit integrity in the test circuits of any of the test articles when exposed to the s se-hour ASTM E119 fire endurance and water hose stream tests. 3. The water hose stream tests did not adversely effect the virgin THERMO-LAG 330-1 Sub11 ming Coating Envelope System remaining on the test articles following the fire endurance tests. 4. The recorded cable surface temperatures in all test articles, after exposure to the ASTM E119 time / temperature environment for a minimum of 60 minutes did not exceed 288'F. 76 l I ) i
e 1 5. The THERMO-LAG 330-1 Subliming Coating Envelope System was manuf actured and applied to each test article in accordance with TSI's Engineering Test Plan, Nuclear Quality Assurance Program Manual and Quality Control Operating Procedures Manual. These documents were accepted by the American Nuclear Insurers, as shown in Section 1 of Appendix I to this report, prior to the consnencement of this test program. Thus, the protective envelope and the manner in which it was applied can be considered typical of those prescribed by TSI, Inc. for nuclear plant installation. 6. Based on information supplied to TSI, Inc. from Operators Engineers and i Constructors of nuclear power plants, it can be assumed that the cable trays, conduit, air drop, instrumentation, equipment and cables installed in each test article, are typical of those found in various nuclear j power generating plants. I i Based on the results and observations of this test program, the THERMO-LAG ) 330-1 Subliming Coating Envelope System meets all the requirements and perf ormance criteria specified in ANI's Bulletin #5(79) for test articles containing " generic" cables. It has also been demonstrated that the protective envelope system provides the required one (1) hour of thermal protection when exposed to the standard ASTM E119 test method ftre environment. e gun 77 ,.. _}}
