1.0 INTRODUCTION

This section describes the THERMO-LAG 330 Fire Barrier System and its material components. The System is comprised of THERMO-LAG Stress Skin Type 330-69 and THER}O-LAG 330-1 Subliming Material. The System may be installed as Prefabrica-ted Panels, Preshaped Sections, 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 Fout (4) basic designs of the THERM 0-LAG 330 Fire Barrier System have applications in nuclear power generating installations. Two (2) of the designs are:

...... Prefabricated Panel Design ......

...... Preshaped Conduit Section Design ......

Each of these basic designs 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 Regulatory Commission.

The material components of each design are identical. Each of the two (2) designs are comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 >

Subliming Material. The designs are either prefabricated or preformed at the factory. ,

The following paragraphs highMBt the majo: ,eteps involved in installing these designs. The more deta;it sequential steps involved in installing these designs are described is 9 : tion II.

1 l

i 2.1 Prefabricated Panel Design l

)

The Prefabricated Panel Design is fabricated and installed at the jobsite' from THERMO-LAG 330-1 Prefabricated Panels. This installation involves cutting the.

number of sections required to form the Fire Barrier from the THERMO-LAG 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 l free space), conduit, instrumentation tubing, junction boxes, structural supports, hangers and fire walls. _ This design is preferred over alternative spray application designs in most nuclear power plant installa-tions because it eliminates the overspray protection requirements of the direct spray-on method.

1 2.2 Preshaped Canduit Section Design The Preshaped Conduit Section Design is shipped to the jobsite ready for- l

. installation. Installation icvolves mounting the preshaped conduit sections on I 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. The precoating of the sections prior to _

installation and. the _ filling in of gaps or 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 j eliminates the overspray protection requirements of direct spray-on methods.

3.0 MATERIAL COMPONENTS The material components which are utilized in the various designs of the THERMO-LAG 330 Fire Barrier System are as follows:

l J

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." THERMO-LAG 330-1 Subliming Material This material provides the level of fire resistance specified for the inutallation. 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 (THERMD-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.

l l

l 3.3 Approved Tie Wires and Banding l 1

ll The tie wires and banding materials for attaching the THERMO-LAG 330 Fire -)

Barrier System, as tested, are 18 gr.. minimum standard stainless steel wire l and 0.020 inch minimum by 1/2 inch miniasm standard stainless steel banding. -

Product data sheets and material refety data sheets for the THERMO-LAG 330 Fire Barrier System are shown in Parts 1.0 and 2.0 of Section III. A recommended on site quality control procedure is shown in Part 3.0. ,j

, A recommended list of installation tools are shown in Part 4.0 of Section III. i 4.0 Primary Raceway Supports and All Penetrations Into The THERMO-LAG 330 Fire Barrier System - Reconnendations i

l

1. . All structural steel supports forming a part or supporting 'the THERMO-LAG 330 fire barrier and the structures, systems and components contained therein which are important to safe shutdown should be protected to provide fire resistance equivalent to that required by the barrier.
e.
2. To prevent thermal shorts into the fire barrier system, all penetrations (i.e. secondary supports, electrical or seismic) into the fire barrier system, should be fire protected to the same level of fire resistance as the raceway for a distance of

, at least 18 inches minimum as measured from the outer surface of the fire barrier; covering all continuous paths. (A fire test report reg'rding a the eighteen inch (18") minimum fire ,

prctection requirement is presenti.d in TSI's Technical Note 84-12-181).

-1.0 Direct Spray 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 fabrication 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 sectione on the entity to be protected, using approved stainless steel tie wires or other approved fastening devices. The installed sections of Stresc Skin are then spray coated with the specified wet 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 Skin 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.

2.0 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 i 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 of the support, followed by the trowel j application of THERMO-LAG 330-1 Subliming Material - Trowel Grade, in the j dry film thickness required to provide,the specified level of fire resistance. l 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.

3.0 THERMO-1.AG 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 will be applied to structural supports and hangers prior to the application of the THERMO-LAG 330-1 Subliming Material.

4.0 THERMO-LAG 350 Two Part Topcoat This material provides excellent protection against water flow and climatic

- variations, chemical attack and physical abuse. It is applied at a spread rate of 50 sq. ft. per gallon.

5.0 PREFABRICATED PANEL DESIGN FOR CONDUIT, CABLE DROPS AND INSTRUMENT TUBING Installation of the Prefabricated Panel Design on conduit, cable drops and instrument tubing involves cutting and forming box sections from one hour or three hour fire rated THERMO-LAG Prefabricated Panels, and then mounting the sections on the conduit, cable drop or instrument tubing to be protected, using approved stainless steel tie wires or other approved fasteners. The sequential steps involved in installing this fire barrier design are described in the following paragraphs.

5.1 Installation of One Hour Fire Barrier Design 5.1.1 Cut two equal sections from a one hour fire rated Prefabricated Panel which are large enough to enclose the conduit, cable drop or instrument tube. The width of each section shall be equal to two times the outer diameter of the conduit, cable drop or instrument tubing.
