t SECTION I GENERAL DESCRIPTION i.0 INTRODUCTION This section describes the THERHD-LAG 330 Fire Berrier System end its meteriel components. The System is comprised of THERHO-LAG Stress Skin Type 330-69 end THERMO-LAG 330-1 Subliming Meteriel. The Systern rney be t instelled es Pref ebriceted Penels, Presheped Conduit Sections, THERMO-LAG 330-660 Flexi-Blenket or by trowel methods. It is used in nucleer power plents to protect ceble treys, conduit, ceble drops (cebles in free spece), junction boxes end structural supports end hengers. THERMO-LAG 330-660 , Flexi-Bleriket is used in the protection of flex conduit end cable drops. 2O FIPE BARRIER DESIGN 5 The designs of the THERMO-LAG 330 Fire Berrier Sy' stem have opplicetions'in nucleer power genereting iristelletions. The designs ere. A. Pref ebricated Penel Design B. Preshaped Conduit Section Design j C. Flexi-Slenket Design Each of these besic designs have been epproved for instellation iri nucleer plant fecilities by the Americen Nuclear Insurers end ere instelled in e number of plants eccepted for operationel licensirig by the Nucleer Reguletory : Commission. 1-1
The meteriel components of A end B are identical. Each of the two (2) designs ere comprised of THERM 0-LAG 5 tress Skin Type 330-69 end THERM 0-LAG 330-1 Subliming Meteriel. The designs are either prefebriceted or preformed et the fectory The meteriel. components of (C) Design is e subliming high tempereture, heet blocking, flexible thermel berrier reinforced on both sides with e low density. fibergiess cloth, further implemented by e heet blocking thermel catelyzer. This design is prefebriceted or preformed et the f actory 21 Pref ebricated Penel Design The Prefebriceted Penel Design is febricoted end instelled et the jobsite from THERMO-LAG 330-1 Prefebricoted Penels. This instelletion involves cutting the number of sections required to form the Fire Berrier from the THERM 0-LAG Prefebriceted Penels end then mounting the sections on the entity to be protected using .020 minimum x .500 minimum steinless steel bending. The essembly is completed by filling in the scored erees end joints. with THERMO-LAG 330-1 Subliming Meteriel-Trowel Grede. The Prefebricoted Penel Design lerids itself to instelletions in the nuclear power generating industry end is used to protect cable trays, ceble drops (cebles in free spece), conduit, junction boxes, structurel supports end hengers. This design is preferred over alternative sprey epplication designs in most nucleer power plent instellations beceuse it elimiriotes the oversprey protection requirernents of the direct sprey-on method. 2.2 Pre @eped Conduit Section Design The Presheped Conduit Section Design is shipped to the jobsite reedy for instelletion. Instelletion involves mounting the presheped conduit sections on the conduit or cable drops to form cyliridricel sections eround the conduit j or ceble drop, end then festening the sections together with .020 minimum x
.500 mimmum steinless steel bending meteriel. The precocting of the j sections prior to instelletion and the filling in of geps or openings et the- ;
edges or joints of the essembled sections is eccomplished usirig THERMO-LAG ! 330-1 Subliming Meteriel-Trowel Grede, et required 1-2 , __. .~ _ _ _ _ _ __ _ _ _ . .
i l 1 The Preshaped Conduit Section Design is used in the nucleer power generating j industry to protect conduit, ceble drops end instrumentetion tubing As with ;
. the Pref abricated Penel Design, this design is elso preferred over alternettve :
- sprey epplication designs in most nucleer power plent instelletions because it eliminetes the oversprey protection requirements of direct sprey-on methods.
2.3_ Flexi-Blenket Design The THERMO-LAG 330-660 Flexi-Blenket Thermel Berrier is e subliming, high temperature, heet blocking, flexible thermel berrier. It is reinforced on both sides with e low density fibergless cloth, further implemented by e heet blocking thermel cotelyzer. The one hour fire reted design of the THERMO-LAG 330-660 Flexi-Blenket Thermel Berrier System is comprised on two (2) eech 0.250 inch nominel thickness legers. The three hour fire reted design of the -THERM 0-LAG 330-660 Flexi-Blenket Thermel Berrier is comprised of five (5) each 0.250 inch nominel thickness legers. THERMD-LAG Fire Reterdent Adhesive is used 4
.to seel the overlep seerris of the Flexi-Blenket legers erid THERHD-LAG 330-660 Bulk Grade Meteriel is used to fill ell joints end openings.
- 3.0 MATERI AL COMPONENTS The meteriel components which ere utilized in the various designs of the THERM 0-LAG 330 Fire Berrier Systern ere es follows:
3.1 THERMO-L AG Stress Skin Type 330-69 This meteriel provides the strong mechenicel bese for the THERMO-LAG 330-1 Sublimirig Heteriel. It is comprised of a pretreeted open weeve, self. stiffened, steel mesh end is used to provide en enclosure over ceble treys, conduits end other items. 1-3 r -- - - - - ' 'w -

3.2 THERMO-L AG 330-1 Subliming Meteriel J This meteriel provides the level of fire resistence specified for the instelletion. It is a weter based, subliming, thermelly ectiveted fire resistive meteriel which volotilizes et fixed temperatures, exhibits e volume increase through the formation of e multi-celluler metrix, and blocks heet to protect the substrete meteriel to which it'is applied This meteriel con be supplied in e sprogeble grede (THERM 0-LAG 330-1 Subliming Heteriel - Spreg Grede) for direct sprey-on opplicetions, or in e trowel grade consistency (THERHO-LAG 330-1 Subliming Heterial - Trowel Grede) which is suiteble for troweling or coulking type opplications. It is further used in the febricetion of Prefebriceted Penels end Presheped or Pref ormed Sections. 3.3 THERMO-L AG 330-660 Flexi-Blenket Thermel Berrier This is e subliming, high tempereture, heet blocking, flexible, thermal berrier. It is reinforced on both sides with e low density, fibergless cloth,' further implemented by e heet blocking thermel cetelyzer. This meteriel is epplied in the required thickness to provide the specified level of fire resistence. i 3.4 Bending , l l l The bending meteriel for etteching the THERMO-LAG 330 Fire Berrier System, ) es tested is .020 minimum x .500 minimurn steinless steel bending. l A required on site quelity control procedure is shown in Section Ill. l l l l l 1-4 l 1

I The next step is to undercut the edges around the cut out section to form e beveled edge. All foreign metter is then removed from the exposed substrete surfece in the cut out section. Finelly, the THERMO-LAG 330 Subliming Meteriel is troweled into the cut out section if necessery, several coets con be opplied to echieve the desired film thickness. Core should be teken to ellow for shrinkege of the repeir petch by building up e slight dome shepe on the surfece of the petch. If the
, demege to the THERMD-LAG 330 Fire Berrier is significent, replace the entire demeged section with e new section using the releted instructions outlined in this menuel.
6.0 C ABLE REPL ACEMENT PROCEDURES The replecement of a cable in e THERMO-LAG 330 Fire Barrier is accornplished by removing sections of the fire berrier, replacing the ceble, end then reinstelling the sections. The first step in this procedure is to rerriove the required number of fire berrier sections by cutting ewey the meteriel et the edges and the butt flenges. Next, the .020 minimum x .500 minimum steinless steel bending ere cut end the fire berrier section removed from the ceble recewey. Af ter the def ective ceble hes been replaced, the fire berrier sections are reinstelled using .020 minimum x .500 minimum steinless steel bending in occordence with the releted instructions outlined in this menuel.' A coeting of THERMO-L AG 330-1 Subliming Meteriel - Trowel Grade is then applied in the specified wet thickness to the edges end joints of the reinstelled sections using e trowel or stiff bristle brush to fill in eng uncooted erees. 9.0 POST APPLICAT10N PRACTICES A cleen end orderly condition shell be meiritained in the instelletiori eree. Following the application, ell debris and equipment shell be removed end the ereS lef t in e conditon eccepteble to the owner. 2-21 .
