Dear Mr. Schwencer:

This letter supplements our letter PLA-683, dated March 26, 1981.

Fire detectors are being installed in all areas of the plant which contain safe shutdown equipment as committed to in Revision 1 to the Susquehanna SES Fire Protection Review Reports Installation of the detectors is scheduled for completion by January 18, 1982.

In the Equipment Room (Fire Zone 0-28B)', we originally committed to two alternative methods for protecting essential safe shutdown raceway from external fire: (1) Wrap-ping the raceways with a one-hour wrap material, or (2) Providing a fire rated false ceiling. Subsequent communication centered around the feasibility of installing a false ceiling. Until recently, no material had been identified which could be utilized as a one-hour wrap for cable capable of preserving the ampacitance rating of the cable in the event of a fire. However, recently such material has been identified and tested. I Test reports for two separate wrapping systems are enclosed. Your concurrence on acceptability of this testing and use of these materials is requested.

PPSL considers a one-hour wrap sufficient to satisfy the original intent of the NRC for protection of the essential safe shutdown raceways in the Equipment Room (Fire Zone 0-28B).

Very truly yours, N. W. Curtis Vice President-Engineering 6 Construction-Nuclear 8111040233 811026 PDR ADOCK 05000387 F PDR

INTRODUCTION There has been increased interest in protecting electrical cables in the event of fire since the Brown's Ferry Nuclear Power Plant fire.

In some areas of nuclear power plants, redundant electrical systems, necessary for the safe shutdown of the reactor, are in close proximity.

Should a fire occur in one of these areas, the redundant electrical sys-tems could be destroyed prior to extinguishment and thereby cause loss of control of the reactor. Fire protection for redundant cable systems, which are essential for the safe shutdown of the reactor is, therefore, needed when they are in close proximity. Fire protection of these re-dundant systems with a one-hour rating is a portion of the overall protection design.

II. OBJECTIVE The objective of this program was to evaluate a fireproofing material for use as a protective covering of redundant electrical systems.

The test procedure used in this evaluation was a modification of the "ANI/MAERP Standard Fire Endurance Test Method to Qualify a Protective Envelope for Class 1E Electrical Circuits" as specified by Pennsylvania Power 5 Light Company.

III. TEST MATERIALS A. Test Slab A concrete floor slab was used for this program. The slab had overall dimensions of 12 ft long x 8-1/2 ft wide x 1 ft thick. The slab was constructed using 1-in. rebar on 12-in. centers and 4000 psi concrete. Cutouts were provided so that wireways, conduits and cable trays could penetrate the slab. A diagram of the test slab is provided in Figure l.

B. Electrical Materials All electrical cable, cable trays, conduits and wireways were provided by Pennsylvania Power 6 Light Company.

The raceway materials basically consisted of:

1. 24 x 4-in. cable trays (open ladder back);

2. 4-in. diameter conduit; and,

3. 6 x 6-in. wireway.

The electrical cable was representative of IEEE 383 approved

cable, The raceway materials were installed so that a vertical drop of approximately 28 in. was made through each cutout and then, each drop was connected via a horizontal run to its corresponding opposite drop.

The installed raceway materials extended above the top of the slab approximately 3 ft. The raceway materials were held in place above the test slab by anchoring each item to two railings of unistrut channel using standard fittings. Figure 2 provides a photograph of this installation.

Electrical cable was then pulled through the raceway materials. The percent fill of each item is provided below.

1. Conduit 1 - 40~a fill

2. Conduit 2 - 40~o fill

3. Cable Tray 1 - 30% fill

4. Cable Tray 2 - 20~a fill S. Wireway 1 - 10~a fill

6. wireway 2 - 40~~ fill C. Fireproofing Materials All fireproofing materials and installation of test materials were provided by Quelcor, Incorporated of Media, Pennsylvania.

Basically, three types of material were used:

1. Quelcor QTHF (0.040 in. thick);

2. QPFR Neoprene (3/16 in. thick); and,

3. QT Aramid.Blanket (nominal 1/8 in. thick),

The method of installation of these materials for each race-way is provided below.

1. Conduit No. 1 (4-in. diameter) with unistrut and bracket Step 1: QT Aramid blanket was applied by wrapping, using a half-overlap to produce two thicknesses of material. Material was applied in 6-in. widths, Step 2: Another layer of QT Aramid blanket was applied (butt wrap) so as to provide a total of 3 layers of blanket.

Step 3: QPFR Neoprene was applied by butt-wrapping, thus providing a single layer of materials Material was applied in 6-in.

widths.

Step 4: Quelcor QTHF was applied using a half-overlap wrap, yielding a two-layer thickness of material. ISidth of material was 6 in.

Step 5: Area of conduit over and around the unistrut mounting bracket was protected by using small pieces of the various pro-tective layers used on the conduit and hand-fitting them. The strut was covered with a protective box fabricated from a 1-in. thick Quelpire panel,

2. Conduit No. 2 (4-in. diameter) with unistrut and blockout This item was protected as Item 1; however, no QPFR Neoprene was used.

3. Cable Tray No. 1 (24 in. wide) with unistrut Step 1: QT Aramid blanket was applied with a half-overlap wrap, thus producing two thicknesses. Material was applied in 6-in. widths.

Step 2: Another layer of QT Aramid blanket was applied using a butt-wrap technique. Total thickness of QT Aramid blanket was three layers. Material was applied in 6-in. widths.

Step 3: QPFR Neoprene was applied by butt-wrapping, thus providing a single layer of material. Material was applied in 6-in. widths.

Step 4: Quelcor QTHF was applied using a half-overlap wrap, yielding a two-layer thickness of mat'erial. width of material was 6 in.

Step 5: Area of tray, over and around the unistrut mounting bracket was protected by using small pieces of the various pro-tective layers used on the tray and hand-fitting them. The strut was covered with a protective box fabricated from a 1-in. thick Quelpire panel.

4. Cable Tray No. 2 (24 in. wide} no unistrut Step 1: QT Aramid blanket was applied as a blanket in two pieces. The first piece covered the bottom of the tray and was folded up so as to cover the sides. The second piece covered the top of the tray. One thickness of material was applied.

Step 2: QT Aramid blanket was again applied as a half-overlap wrap, thus providing a total of three thicknesses of blan-ket. Material was applied in 6-in. widths.

Step 3: QPFR Neoprene was applied using a butt-wrap technique. A single layer of material was applied. Material was applied in 6-in. widths.

Step 4: Quelcor QTHF was applied in half-overlap fashion, thus providing two thicknesses of material. Material was applied in 3 and 6-in. widths.

5. wireway No. 1 Step 1: The QT Aramid blanket was applied as a three-layer blanket. The 90'orners were protected with custom-fitted pieces of blanket. The inner corners were built up to the level of the flanges using a small section of 1-in. Quelpire panel.

Step 2: Quelcor QTHF was applied using a half-overlap wrap, thus providing two layers. The corners were custom-fitted using two layers of Quelcor QTHF.

6. wireway No. 2 blanketed Step 1: The QT Aramid blanket was applied as a three-layer blanket. The 90'orners were protected with custom-fitted pieces of The inner corners were built up to the level of the flanges by using a small section of 1-in. Quelpire panel.

Step 2: A single layer of QPFR Neoprene was applied as a blanket.

Step 3: Quelcor QTHF was applied using a half-overlap wrap, thus providing a two-layer thickness. The corners were custom-fitted using two layers of Quelcor QTHF.

Figure 3 provides a photograph of the completed test articles.

The fireproofing materials were also evaluated at SwRI using the ASTM E84 Flame Spread test procedure. The materials were exposed using a wire screen for support. The results of these evaluations are as follows:

A. Temperature Measurements A total of twenty-nine thermocouples were used to monitor temperatures at various locations. The thermocouples consisted of 22-gauge Type K thermocouple wire. The output of the thermocouples was monitored using a Kaye Instruments Digi-Strip digital recorder and a i1estronics 0-2000'F multi-point recorder. Actual location of the thermo-couples is described in Table I and shown schematically in Figures 4 through 10.

B. Electrical Instrumentation The primary criteria for pass/fail in this test was the determination of short-cicuits that might develop in the raceways due to failure of'he fireproofing material. In order to monitor circuit in-tegrity, and detect shorts, a light panel arrangement was constructed.

This panel arrangement is detailed in Figure 11.

The wiring of the cables in each raceway was performed by Bechtel and Pennsylvania Power 5 Light Company personnel.

V. TEST PROCEDURES The overall test procedure followed in this program was the "ANI/MAERP Standard Fire Endurance Test Method to Qualify a Protective Envelope for Class lE Electrical Circuits" with modifications as reques-ted by Pennsylvania Power 5 Light Company. A copy of this procedure and modifications is provided in Appendix A.

This Standard has been through several drafts and has benefited from suggestions from vendors, utilities and architect engineers.

This Standard is meant to meet a current need for qualifying a protective envelope for redundant safety circuits located in the same fire area. Although we don't envision industry-wide application of the protective envelope concept, we believe that it may provide a practical retrofit solution for a significant number of existing operating plants and some plants currently under construction.

iUUCLLAR 8URT C.PROOM,(PCU SSURERS ANI/ftAERP STANDARD FIRE'NDURANCE TEST METHOD TO qUALIFY A PROTECTIVE ENVELOPE FOR CLASS 1E ELECTRICAL CIRCUITS

1. 0 INTRODUCTION The ANI/MAERP "Basic Fire Protection Guidelines" (April, 1976) recommend that redundant safety circuits be cut-off from each other by standard fire walls and floors (Item I, E-6). It has been our experience, that in new designs, this feature is "built-in". However, for operating plants, and some plants nearing completion, the provision of standard, rated, fire barriers may not be practical. Mhen this condition exists, the options are to relocate the v.ital circuit to another fire area, or protect them in place.

"Protecting-in-place" is defined as the 'ability to maintain the circuit's function during a standard exposure fire by use of a Protective Envelope.

In an effort to provide, for insurance purposes only, a reasonable and l'e-liable means of "protecting-in-place" these vital circuits, without limiting our Insureds to conventional methods, and giving them the option of using products/materials not normally se'en in this type of application, we have developed this test method. In this manner evaluations of different products/

materials can be made, using a standard test approach.

A In developing this Standard Test Method, the need to maintain circuit integ-rity during a standard "temperature-time" fire exposure was the prime con-sideration. In addition, the ability of the Protective Envelope to contain an internal fire exposure, was also considered important.

It should be emphasized that this Standard Test Method in no way decreases our requirements for fixed automatic fire suppression systems nor will it be considered the equivalent of rated fire barriers, where required. Its intent is to provide a means for "protecting-in-place" redundant cable systems in existing plants, or unusual situations in new designs, for insurance ~ur uses

GENERAL METHOD OP OPERATION THERMO-LAG compounds provide a highly effective heat blocking function, primarily through the mechanism of sublimation.

Upon exposure to heat, as the temperature of sublimation is attained, a transition from the solid phase to a vapor phase

.takes place. This is associated with the absorption of approximately 750 Btu's per pound. The sublimate vapors are subjected to further- energy absorbing reactions through endothermic decomposition. The endothermic decompostion reactions can absorb as much as 6000 Btu's per pound. During pyrolysis of the binder system, a char layer is formed which is made to expand by action of the sublimate gases".

=Since the char layer is composed of small interconnecting cells having a large surface area, ~t fun'ctions as an efficient heat exchanger. With expansion of the char layer, the path followed by the sublimate gases is lengthened and the time of contact between the sublimate gases and the high temperature cellular structure is increased.

The combined effects result in increased efficiency of the endothermic decomposition mechanism; The ability of the -char

.layer to attain high temperatures further results'n significant re-radiation of energy and. a reduced heat transfer coefficient.

The low conductivity of the light cellular char structure also performs an insulatiye function.

. has been approved'by major fire underwriters in high hazard areas in chemical, industrial and chemical processing plants and oil refineries.

is water based, eliminating the fumes, toxicity and fire hazards associated with solvent type coatings.

contains no asbestos.

is permanent fireproofing - even "when out of sight and out of mind" - does not dust, flake, spall, chip, crack or fall off. THERMO-LAG stays on the job year after year.

is economical compared with sprayed-on fireproofing that must be protected by enclosure.

sprays on fast, direct from shipping container without mixing can also be trowel applied.

excellent weathering resistance when fully cured allows exposure to the environment (40.0 years minimum).

minimal coating thickness required allows the aesthetically desirable architectural expression of the steel shapes to be maintained.

raw materials readily available, no toxic solvents.

. maintenance free - less durable materials need repairs negating any initial cost savings.

high resilience - elongation capability accommodates steel flexure and dimensional changes due to windloading and temperature variations (15% elongation, coefficient of thermal expansion 16 x 10-6 in/in/'F).

high bond strength -(100 psi).

thermal qualities insulating qualities at ambient temperatures. Fire conditions - acts as a. weather jacket.

ABSTRACT A requirement delineated in Federal Regulation 10CFR Part 50 exists to enhance critical operating load carrying and infor-mation transmitting components of Nuclear Power Generating Facilities with specified levels of fire resistance enhancement.

THERMO-LAG 330-1 Subliming Coating Envelope System has been carefully tested in an entire spectrum of environments encom-passing the above prerequisites to establish and confirm its performance capabilities and its ability to meet the prere-quisites of this Regulation.

Numerous tests wexe performed at the facilities of the Underwriters Laboratoxies, TSI Fixe Simulation Facilities, U. S. Army Aberdeen Proving Ground, Maryland, Factory Mutual Research Corporation, Marrington Reseach Laboratories in England under the supervision of Lloyd's of London, and elsewhere.

The resultant data clearly establi'shes that THERMO-LAG 330-1 Subliming Coating Envelope System meets these prerequisites.

The data presented herein-clearly demonstrates that the System is capable of providing three (3) hour fire resistance to a barrier as per ASTM E119 Time/Temperature transmission, prerequisites and as per IEE 634 IEEE Standard Cable Penetration Fire Stop Qualification Tests. In addition this is further supported by a considerable amount of testing performed by

the Underwriters Laboratories at its facilities, during the environmental and life cycle tests all fo11owed by ASTH E119 Type Fire Simulation Tests, the Department of Transportation, U. S. Army ,'berdeen Proving Ground testing, Warrington Research testing under the supervision of Lloyd's of London for North Sea Fire Wall deployment; and elsewhere;- All of these tests are identified and listed in detail in sections which follow.

Design Nomographs are also presented which relate the heat flux of the anticipated fire to the thickness of the material, the maximum backside temperature allowed and duration of the.

fire.

Results of extensive tests performed on solid and ladder back cable trays, conduit and cable drop assemblies performed

.under conditions of ASTM E119 Time/Temperature Environment further demonstrates the capability of this System to meet the prerequisites of 10CFR Part 50, Appendix R, Paragraph. G, Fire Protection For Safe Shutdown CapabiI.ity..

Results of tests conducted by the Underwriters Laboratories on the components of this System under ASTM E84 condi'tions demonstrate that all components have a Flame Spread of less than 15, Fuel Contributed and Smoke Developed of '0. The anticipated life of- the system is at least 40-years.

TSE is prepared to back this with a warranty', the details of which are delineated in the attachment.

Aberdeen Proving Ground, under the auspices of the Department of Transportation performed seismic and other flutter and vibration tests which clearly demonstrate the superior resis-tance of this System to this potential environment. Ampacities .

tests were performed which further indicate that the System will not be derated under conditions of maximum current load application with the individual temperatures on the surface, of the cable below 90'C as required by IPCEA Publication P-54-440-WC-51-1972 "Ampacities - Cables in Open Top Cable Trays."

THERMO-LAG 330-1 Subliming Coating System has been used for a number of years at Rocky Flats Nuclear Materials Manufacturing Facilities with good results. While tests are believed to have been .conducted on Nuclear Irradiation of the physical properties of this material without any detrimental results, such tests will be repeated in the very near future.

TSI does have..a rigorous Quality Assurance and Quality Control system which meets all the prerequisites of the NRC and ANI.

An outline of that system is presented herein.

TSI's THERMO-LAG Subliming Barrier Coating System has been in use since the 1950's, initially for t'e protection of aerospace exit and re-entry vehicles such as X-15 Airplane, Apollo, Polaris-Missiles, Communication Satellites, and many others.-

h THERMO-LAG Materials are li.sted and classified by the Underwriters Laboratories,. approved by- Lloyd's of London and other authorities for use at North Sea Offshore Installations and elsewhere, and

- have been extensively used for fire resistive enhancement in .

the United States and globally. A list of THERMO-LAG'Users is also presented herein.

TSI's detailed and recommended application procedures are also included herein for reference.
