1.0 INTRODUCTION

This section describes the THERMO-LAG 330 Fire Barrier System and its material co=ponents. The System is comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. The System may be installed as Prefabri-cated Panels, Preshaped Section, or by direct spray or trowel methods. It is used in nuclear power plants to protect cable trays, conduit, air drops (cables in free space), junction boxes and structural supports and hangers. 2.0 FIRE BARRIER DESIGNS Four (4) basic designs of the THERMO-LAG 330 Fire Barrier System have applications in nuclear power generating installations. These four (4) designs are: Prefabricated Panel Design Preshaped Conduit Section Design Direct Spray Over Stress Skin Design Direct Spray-On Design Each of these basic designs or combinations have been approved for installation in nuclear plant facilities by the American Nuclear Insurers and are installed in a number of plants accepted for operational licensing by the Nuclear Regula-tory Commission. The material components of each design are identical with the exception of the Direct Spray-On Design. Each of the first three (3) designs are comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. The only difference between these three designs is that two of them are either prefabricated or preformed at the factory and the third is field sprayed at the jobsite. The Direct Spray-On Design differs from the other three designs in that it does not include the Stress Skin component. The following paragraphs highlight the major steps involved in installing these designs. Ihe more detailed sequential steps involved in installing these designs are described in Section II. 1-1

l ~ l s 2.1 Prefabricated Panel Design The Prefabricated Panel Design is fabricated and installed at'the jobsite from THERMO-LAG 330-1 Prefabricated Panels. number of sections required to form the Fire Barrier from the THEPJiG-LAGThis ins Prefabricated Panels and then mounting the sections on the entity to be protected using approved stainless steel tie wires or other approved fasteners. The assembly is completed by filling in the scored areas and joints with THERMO-LAG 330-1 Subliming Material - Trowel Grade. The Prefabricated Panel Design lends itself to installations in the nuclear power generating industry and is used to protect cable trays, air drops (cables in free space), conduit, instrumentation tubing, junction boxes, structural supports, hangers, fire walls, wirevays, and other associated equipment. design is preferred over alternative spray application designs in most nuclear This power plant installations because it eliminates the overspray protection requirements of the direct spray-on method. 2.2 Preshaced Conduit Section Design The Preshaped Conduit Section Design is shipped to the jobsite ready for installation. Installation involves mounting the preshaped conduit sections on the conduit or cable drops to form cylindrical sections around the conduit or cable drop, and then fastening the sections together with approved stainless steel tie wires or banding material. installation and the filling in of gaps orThe precoating of the sections prior to openings at the edges or joints of the assembled sections is accomplished using THERMO-LAG 330-1 Subliming Material - Trowel Grade, as required. The Preshaped Conduit Section Design is used in the nuclear power generating industry to protect conduit, cable drops and instrumentation tubing. As with the Prefabricated Panel Design, this design is also preferred over alternative spray application designs in most nuclear power plant installations because it eliminates the overspray protection requirements of direct spray-on methods. 1-2 1

s 2.3 Direct Soray over Stress Skin Design The Direct Spray Over Stress Skin Design consists of field fabrication of a -Stress Skin envelope followed by a direct spray application of the THERMO-LAG 330-1 Subliming Material - Spray Grade. The fabrftstion of the Stress Skin envelope involves cutting the number of sections of THERMO-LAG Stress Skin Type 330-69 required to form the Stress Skin envelope, and then mounting these sections on the entity to be protected, using approved stainless steel tie wires or other approved fastening devices. The installed sections of Stress Skin are t hen spray coated with the specified vet film thickness of THERMO-LAG 330-1 Subliming Material - Spray Grade. As an alternative, the fabricated sections of Stress Skin may be spray coated prior to mounting. In either case, the coating must be spray applied in accordance with instructions given in Section II. The Direct Spray Over Stress Okin Design lends itself to installation in the nuclear power generating industry where the overspray protection requirement is not a consideration and is used to protect cable trays, conduits, cable drops, junction boxes, structural supports, hangers, and fire walls. 2.4 DIRECT SPRAY-ON DESIGN The Direct Spray-On Design is used for coating cables installed in a cable tray. This design. involves spraying the cables and the inside and outside surfaces of the. cable trays with a continuous film of the THERMO-LAG 330-1 Subliming Material - Spray Grade. This material should be spray applied in accordance with the instructions given in Section II. The Direct Spray-On Design also is used to coat conduit where overspray protection is not a consideration. This design involves spraying the conduit surface with a continuous film of the THERMO-LAG 330-1 Subliming Material - Spray Grade. The coating should be spray applied in accordance with the instruction given in Section II. A special adaptation of the Direct Spray-On Design is the Direct Trowel-On Design used for protecting cable tray and conduit supports. This design involves an initial brush or roller application of THERMO-lag 351 Primer over the properly prepared surface cf the support, followed by.the trowel application of THERMO-LAG 330*! Subliming Material - Trowel Grade, in the dry film thickness requires *e an*<ide the specified level of fire resistance. .The Direct Spray-On Design and its special adaptation are used in applications within the nuclear power industry to protect cable trays, structural supports and hangers. 1-3

3.0 MATERIAL COMPONENES, S The material components which are utilized in the various designs of the THERMO-LAG.330 Fire Barrier System are as follows: 3.1 THERMO-LAG Stress Skin Type 330-69 This material provides the strong mechanical base for the THERMO-LAG 330-1 Subliming Material. It is comprised of a pretreated open weave, self stiffened, steel mesh and is used to provide an enclosure over cable trays, conduits and other items. 3.2 THERMO-LAG 330-1 Subliming Material This material provides the level of fire resistance specified for the installation. It is a water based, subliming, thermally activated fire resistive material which volatilizes at fixed temperatures, exhibits a volume increase through the formation of a multi-cellular matrix, and blocks heat to protect the substrate material to which it is applied. This material can be supplied in a sprayable grade (THERMO-LAG 330-1 Subliming Material - Spray Grade) for direct spray-on applications, or in a trowel grade consistency (THERMO-LAG 330-1 Subliming Material - Trowel Grade) which is suitable for troweling or caulking type applications. It is further used in the fabrication of Prefabricated Panels and Preshaped or Preformed Sections. 3.3 THERMO-LAG 351-2 Primer This is a highly efficient corrosion inhibiting primer which is applied to properly prepared steel surfaces at a spread rate of circa 200 sq. ft. per gallon. This material vill be applied to structural supports and hangers prior to the application of the THERMO-LAG 330-1 Subliming Material. 3.4 THERMO-LAG 350 Two Part Topcoat This material provides excellent protection igainst vater flow and climatic variations, chemical attack and physical abust. It is applied at a spread rate of 50 sq. ft. per gallon. 1-4

11.3.2 Install a one hour or three hour fire rated Preshaped Conduit j section on a conduit or cable bundle penetrating a cable tray l fire barrier for a minimum distance of eighteen inches from the l point of penetration as is shown in Figure 21. 11.3.3 Apply a coating of THERMO-LAG 350 Primer to the horizontal structural support mecher and to the vertical structural supports from the horizontal support me=ber to the ceiling, vall or floor support prior to the trowel application of one or three hour fire protection. Also apply the primer coating to e penetrating structural member for a minimum distance of 18 inches from its point of intersection with a cable tray fire barrier prior to the trowel application of one or three hour fire protection. 11.3.4 Trovel apply a coating of THERMO-LAC 330-1 Sub11 ming Material - Trowel Grade in a dry film thickness of 0.625" +/- 0.125" for one hour fire protection and 1.250" +/- 0.25" for three hour fire protection. { i l 12.0 COATING APPLICATION TECHNIQUES ] l 12.1 THERMO-LAG 351 Primer Application I 12.1.1 Prepare the surface of the steel entity for application of the THERMO-LAG 351 Type Primer by removing any dirt, scale, rust or other contaminants. Never apply the primer directly over any hard or glossy painted surface without roughening the surface in accordance with standard painting practices. 12.1.2 Make sure that the cleaned steel surface is compatible with the j THERMO-LAG 330-1 Subliming Material by making cross hatch adhesion i tests as follows: . Cross Hatch Adhesion Test The primer is cut over an area approximately 4" by 4" in a square matrix, each square being approximately 1/2" by 1/2". A high quality tape is applied diagonally to the square. Upon completion of the tape application. it is rubbed in firmly to assure good adhesion. With one co=plete jerking motion, the tape is removed. If more than 3 percent of the Primer is removed from the surface, the application is faulty. This test should be performed in areas which are deemed critical and in as many places as required by the specification. Upon completion of the Cross Hatch Adhesion Test, the test areas should be again with the THERMO-LAG 351-2 Primer by either brushing or light spray. 2-45

1 1 Always apply a barrier coat of THERMO-LAG 351 Type Primer over steel surfaces which have been previously primed with a zine based primer. All doubtful surfaces should be removed using mechanical cleaning methods. 12.1.3 Apply the Primer to the properly prepared steel surface in one continuous coat using spray equipment, brush or roller. The minimum acceptable dry primer thickness should be 0.002 inches which is normally achieved by applying at a spread rate of circa 200 sq. ft. per gallon. 12.1.4 Measure Primer thickness using an approved magnetic direct reading gauge. 12.1.5 Make cross hatch adhesion tests on the primed surface to assure proper. adhesion between the primer and the surface of the steel item prior to proceeding with the application of the THERMO-LAG 330-1 Subliming Material. 12.1.5 Coat the primed steel surface area with the THERMO-LAG 330-1 Subliming Material. The coating shall be applied in accordance with instructions given in Paragraph 12.2 or 12.3 herein. 12.2 THERMO-LAG 330-1 Subliming Material - Spray Application 12.2.1 Apply the THERMO-LAG 330-1 Subliming Material - Spray Grade over a properly prepared surface. Make sure that the surface to be coated is clean, dry, above 40 F and free from scale, rust or other contaminants. 12.2.2 Apply the material in as many passes as required to provide the required dry film build of the coating thickness, taking care to avoid slumping or sagging of the coating. Normally, a required 0.500 inch dry film coating thickness is accomplished by applying three wet coats of 0.255 inches. However, the thickness which can be safely applied in a single pass will depend on the temperature, humidity and other factors that are best determined on the jobsite. 12.2.3 Apply the material in smooth even passes, taking care to keep the spray gun fan pattern at a 90 degree angle whenever possible. Reaching with a spray gun will cause the spray pattern to vary from the 90 degree angle and will result in a rougher surface than normal. 2-46

w n 12.24 Take frequent vet thickness measurements during the application using a penetration measuring device to ensure that the coating is being applied uniformly and at the required wet. film thickness. These wet thickness checks shall be made every five (5) square feet or every rvo (2) running feet of coated surface area. (Note: When taking measurements, allow for a shrinkage rate of circa 25' between the wet and the desired dry film coating thickness.) 12.2.5 Remove ' excess build 'up yof coating material at edges and joints by brushing or rolling the surface with a damp sponge roller or a nylon bristle brush. 12.2.6 Spray edges of the substrate from each side to cause the material to - vrap around the edge. If the edge coating is not completely closed, use a wet roller or trowel to seal the edge surface. 12.2.7 Remove all runs, sags, drips or other surface imperfections before the material cures, using wet sponge rollers, brushes or hand trowels. 12.3 THERMO-LAG 330-1 Subliming Material Trowel Application 12.3.1 Trowel the material to a uniform thickness using moderate pressure and avoid overworking. The trowel should be wetted with water when a smooth finish is required. 12.4 Dry Film Thickness Heasurements 12.4.1 Take dry film thickness measurements after the applied material has cured. Measurement shall be made using electrical, penetrating or magnetic measuring instruments.- 2-47 Ywrd 1ei. vT- -+ w m-w ee-a -e-W m ev w --w-ww em a er :-.=-+ vi--- e--

i 13.0 REPAIR PROCEDf1RES The repair of a damaged section in a THERMO-LAG 330 Fire Barrier is easily accomplished by cutting out and removing the da ged material and then filling in the cut out section with new material. The first step in this procedures is to remove the damaged and loose material using a knife and scraper. Care should be exercised that the damaged material t is cut back until sound adhering material is reached. 1 The next step is to undercut the edges around the cut out section to form a beveled edge. All foreign matter is then removed from the exposed substrate surface in the cut out section. Finally, the THERMO-LAG 330 Subliming Material is sprayed or troweled into the cut out section. If necessary, several coats can be applied to achieve the desired film thickness. Care should be taken to allow for shrichsge of the repair patch by building up a slight dome shape on the surface ot the patch. l 2-48

t -14.0 CABLE REPLACEMEhr PROCEDURES The replacement of a cable in a THERMO-LAG 330 Fire Barrier is accomplished by removing sections of the fire barrier, replacing the cable, and then reinstalling the sections. The first step in this procedure is to remove the required number of' fire - barrier sections by cutting away the material at the edges and the butt flanges. d Next, the stainless steel tie wires or banding are cut and the fire barrier section removed from the cable raceway. After the defective cable has been replaced, the fire barrier sections are reinstalled using approved stainless steel tie wires or banding. A coating of THERMO-LAG 330-1 Sublicing Material - Trowel Grade is then applied in the specified wet thickness to the edges and joints of the reinstalled sections using a trowel or stiff bristle brush to fill in any uncoated areas. 15.0 POST APPLICATION PRACTICES A clean and orderly condition shall be maintained in the installation area. Following the application, all debris and equipment and any.overspray shall be removed and the area left in a condition acceptable to the owner. 2-49 I i f
