SUBJECT:
REQUEST FOR ADDITIONALINFORMATIONREGARDING NINE MILE POINT NUCLEAR STATION, UNIT 2 RESPONSE TO GENERIC LETTER 92-08, "THERMO-LAG 330-1 FIRE BARRIERS" By letter dated June 16, 1993, the Staff requested additional information regarding Nine Mile Point Unit 2's response to Generic Letter 92-08, "Thermo-Lag 330-1 Fire Barriers". The Staff requested additional information on the acceptance criteria and test methods used for establishing the 3-hour rating of Thermo-Lag fire barriers installed at Nine. Mile Point Unit 2. Also requested are all test reports that document the ampacity derating characteristics of the fire barrier installed; the Staff also requested that Niagara Mohawk identify what ampacity derating margin exclusive of typical derating factors (i.e., ambient temperature, cable fill) is available for Thermo-Lag 330-1 related ampacity factors.
Attached is the additional information requested regarding the 3-hour ratings. All of the requested reports were obtained from microfilm. No testing has been performed to determine ampacity derating characteristics. The only Thermo-Lag protected power cable at Nine Mile Point Unit 2 is cable 2SWPAG017, which supplies motor operated valve 2SWP~MOVSOA. Niagara Mohawk believes that due to the intermittent operation of motor operated valves, cables supplying the motor operators will not reach rated temperatures, and therefore, no derating factors are necessary.
Nine Mile Point Unit 2 design for sizing all Motor Operated Valve (MOV) cables is as follows:
(1) Due to the short time operation of MOVs, no derating for raceway is required.
(2) Ampacity of the cable is based on 55 percent of the locked rotor current or 300 percent of the full load current rating of the MOV, but not to exceed 300 percent of the motor full load current.
4p >j O O w O
(3) The ampacity of cable is determined based on design criteria 2 above, and then the required derating factor for ambient temperature (only) is applied, since no derating is required for raceways based on design criteria 1 above.
( 930836013l 930819 ADOCP:. 050004i0.
Page 2 For the specific Thermo-Lag protected MOV installation at NMP2, the following derating factors apply:
(1) Ambient temperature derating factor - none required since the cable is rated for 40'C and routed in 40'C ambient.
(2) Cable fill derating factor - none required since the cable is normally in de-energized condition and is energized only for a short-time operation.
(3) Ampacity derating margin available exclusive of typical derating factors-0.79.
In addition, the design of NMP2 power cables for the Thermo-Lag protected installations is conservative for the following reasons:
(a) Normally, the thermal overload relays that protect MOV power cables from overload conditions are sized based on 200 percent of the motor full load current, and the cables sized for 200 percent of the motor full load current, are adequate. To provide additional conservatism, NMP2 power cables for MOVs are sized for 300 percent of the motor full load current.
(b) No derating factor is needed to be applied for the Thermo-Lag wrapping for the NMP2 installation. However, based on item "a" above, a derating factor of 0.52 (cable is oversized by 100%) can be applied to the subject cable for Thermo-Lag, and the cable can still perform its function satisfactorily.
Ifyou have any questions or need more information, please contact Mike Carson at 315-428-7470.

DESCRIPTION This section describes the THEE".0-L'.G 330 Fire Barrier System and its f've (i) basic designs. ihe System is used in power generating plants to protect cable trays, conduits, cable drops, instrument tubing, junction boxes, pullboxes, condulets, structural supports, hangers and fire damper frames.
B. FIRE BPZRZER DESZG'.:S Five (5) basic designs of the THERMO-LAG 330 Fire Barrier System have application in power generating installations. These five designs are:
Prefabricated Panel Design Preshaped Conduit Section Design Direct Spray Over Stress Skin Design Direct Spray-On Design ~ ~ ~ ~ ~
330%60 Flexi-Blanket Thermal Barrier Design Each of these basic designs have been installed in a number of plants throughout the United States and overseas; .
4 The macez'al components of the first three designs are identical. Thev are comprised oz THERMO-LAG Stress Skin Type 330-69 and THER"fO-LAG 330-1 Sublimirg
.Material. The only difference between these three designs is that the first.
two (2) are prefabricated or preformed at the factory, while the third is field sprayed at the 5obsite. The Dizect Spray-On Design differs fzom the other three designs in cha it does not incluce che Stress Skin compo<<enc., The THEiQfO-LAG 330-660 Flexi-Blanket Thermal Barrier Design is completely different since it is comprised of a heat blocking thermal catalizer reinforced on both sides with a low density fiberglass cloth.
The following paragraphs describe each design and highlight the steps involved in installing these designs. More detailed sequential installation procedures are described in Sections II through VII of this Installation Procedures Manual.
I. THERMO-LAG Prefabricated Panel Desizn (a) Co=oosit'on A ~r=<fO-LAG Pzefabr'cated Panel is comprised of i~~wfO-LAG Stress Skin Type 330-69 and IHZR~10-LAG'30-1 Subliming Material. These panels are normally supplied in 4 foot by 64 foot sheets, and manufactured in 30 minute, one hour and three hou" f'ze zat d designs as follows:
A 30 minute design consists o" an inner layer of THE~f0-LAG Stress Skin Type 330-69 and an outer layer of 0.250 inch minimum dry film thickness of the THERMO-LAG 330-1 Subliming Material.
A one hour design consists of an inner layer of THERMO-LAG Stress Skin Type 330-69 and.ari outer layer of 0.500 inch minimum dry film thickness of the THERMO-LAG 330-1 Subliming Material.
A three hour design consists of an inner layer of THERMO-LAG Stress Skin Type 330-69, a 'center layer of 1.00 inch minimum dry film thickness of. the THERMO-LAG 330-1 Subliming Material, and an outer layer of THERMO-LAG Stress Skin Type 330-69.
(b) Installation Details The, installation involves cutting the number of sections required to form the fire barrier from the THERMO-LAG"Piefabricated Panels, and then mounting the sections on the entity to be protected using 18. ga. minimum stainless steel tie wires, 0.5" x 0.020" minimum stainless steel banding material, or other appzoved fasteners. The assembly is completed by filling in the scored areas, where applicable, and points with the THERMO-LAG 330-1 Subliming Tzowel Grade.
Material, as required. The Prefabricated Panel Design is used to protect cable trays, function boxes, pullboxes, condulets, structural supports, hangers, and fire dampers.
This design is preferred over alternative spray applications because it eliminates the overspzay protection requirements of the direct spray-on method.
II. THERMO-LAG Pzeshaoed Conduit Desi n (a) Comoosit'on A THERMO-LAG Pzeshaped Conduit Section is comprised of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. THERMO-LAG Preshaped Conduit Sections are cylindrically shaped, half moon sections, and are supplied in 3 foot nominal 1'engths of the specified nominal diameter. The conduit sections are manufactured in one and three hour fire rated designs as follows:
A 1 hour fire rated Preshaped 'Conduit Section consists of an inner layez of THERMO-LAG Stzess Skin Type 330-69 and an outer layer of'0.500 inch mixdunsn dry film thickness of the THERMO<<LAG 330-1 Subliming Material.

I-3
(b) installation Details The installation involves mounting the preshaped conduit sections on conduit, flex cable or cable drops and instrument tubing to form cylindrical sections around the entity, and then fastening the sections together with 18 ga. minimum stainless steel tie wires or 0.5" x 0.020" minimum stainless steel banding mater'al. The precoating oi the sections prior to installation and the filling in of gaps or openings at the edges or points of the-assembled sections is accomplished by using the THERMO-LAG 330-1 Subliming Trowel Grade Material, as required.
The Preshaped Conduit Section Design is used to protect conduit,. flex cable or air cable drops, and instrumentation tubing. As with the THERMO-LAG Prefabricated Panels, this design is also preferred over alternative spray applications because it eliminates the overspray protection requirements of direct spray-on methods.
III. Direct Spray Over Stress Skin Design (a) Comoosition The Direct Spray Over Stress Skin Design is comprised of THERMO-LAG Stress Skin Type 330-59 and THER~0-L4G 330-1 Subliming Materia'.

A one hour design consists of an inner layer of THERMO-LAG Stress Skin Type 330-69 and an outer layer of 0.500 inch minimum dry film thickness of the THERMO-LAG 330-1. Subliming Material.
A three hour design consists of an inner layer of THERMO-LAG Stress Skin Type 330-69, a center layer of 1.00 inch minimum dry film thickness of the THERMO-LAG 330-1 Subliming Material, and an outer layer. of THERMO-LAG Stress Skin Type 330%9.
The'Stress Skin is normally supplied in 4 foot by 8 foot sheets. THERMO-LAG 330-1 Subliming Material is supplied in 500 net lb. drums.
(b) Xnstallat'o.. De"as The fabr'cat'on of the Stress Skin envelope involves cutting the number of sections of Stress Sk'n requ'red' xorm tha e"..'e'ope, and then mounting t'.-.es sections on the entity to be protected, using 18 ga. mini um stainless steel tie wire, 0.5" x 0.020" minimum stainless steel banding'aterial, staples or other aporoved fasteners. .The installed sections of Stress Skin are then spray coated with the specified wet film thickness of the THERMO-LAG 330-1 Subliming Material required to px'oduce a 0.500 inch minimum dxy film thickness for the one hour fire rated design and a 1.00 inch minimum dry film thickness for the thx'ee hour fixe rated design. An outer layer of Stress Skin is mounted over the cuxed subliming material in the case of the three hour fire rated design only.
As an alternate, 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 other sections of this Installation Procedures Manual. The Direct Spray Over Stress Skin Design is used where the overspray protection requi.re ents are not a consideration, and is used'o protect cable trays, concuits, cable drops, instrumentation t bing, junction boxes, pullboxes, condulets, structural supoorts and hangers.
I'1. D'rect Spray-On Desizn (a) Co oosition The Direct Spray-On Design consists of applying a continuous film of the THERMO-LAG 330-1 Subliming Material in the required thickness to provide the specified level of fire x'esistance.
(b) Installation DetAils This design involves spraying conduit. or cables, together with all. surfaces of the cable tray, with a continuous film of the THERMO-LAG 330-1 Subliming
~ ~
Material, applied in a dry film thickness to provide one hour's fix'e resistance. This application is used when overspray protection is not a consideration.
A special adaptation of the Direct SprayOn Design is the Direct Trowel-On Design which is used to protect cable tray and conduit supports. This design involves an initial brush or roller application of the THERMO-LAG 351-2 Primer over the properly prepared surface of the support, followed by the trowel application of the THERMO-LAG 330-1 Subliming Trowel Grade Material, applied in a dry film thickness to provide the specified level of fire resistance. In the case of dull galvanized surfaces, the Primer application is not required.

TSI TECHNICAL NOTE 20684 SECTION Ii THERMO-LAG 330 FIRE BARRIER SYSTEMS FOR PROTECTION OF CABLE TRAYS The three (3) basic designs of the THERMO-LAG 330 Fire Barrier System, used to provide thermal protection for cable trays installed in power generating plants, are:
Prefabricated Panel "Ready Access" Design Direct Spray Over Stress Skin Design Direct Spray-Or Design The material components of the first two (2) designs consist of THERMO-LAG Stress Skin Type 330-69 and THERMO-LAG 330-1 Subliming Material. The between these two (2) designs is that the Prefabricated Panel Ready only'ifference Access Design is prefabricated at the factory and the Direct Spray Over Stress Skin Design is field sprayed at the Jobsite.
The Direct SprayOn Design is comprised of THERMO-LAG 330-1 Subliming Material
~
~ which is also sprayed at the Jobsite and but does not include the THERMO-LAG Stress Skin Type 330&9.
The following paragraphs set forth the sequential steps involved in installing these three (3) designs.
'l p
1.0 P %FABRICATED P~NEL READY ACCESS DESEG~; FOR CABL. TRAYS Installation of the Prefabricated Panel Ready Access Design to cable trays involves cutting the numoer oi sections required to form the Fire Barrier fzom one o three hour fire rated THERMO-LAG P" abz'cated Panels, foxing <<he Fire Barzier sections by making 90 degree bends, and then mounting the sections on the cable tzay to be protected using 1S ga. minimum stainless steel tie wize or 0.5" x 0.020 inch minimum stainless steel banding material.
The forming of the fire barrier sections is 'accomplished using one of several methods. Three (3) and four (4)'sided one (1) piece sections are formed by scozing, in the case of one hour fire rated panels, or by cutting a "V" groove, in the case of the three hour fire rated panel, along the lines where bends are to be made and then making the required 90 degree bends. The sections aze then completed by tieing or banding the sides together and filling in the scored or "V" cut corners with THERMO-LAG 330-1 Subliming Tzowel Grade Mi terial.
Zn the other alternative method, individual top, bottom and side pieces aze either butt or miter cut fran the one or three hour fire zated panel and are then tied or banded together. The seams and ')oints of the sect'on cze then filled using THERMO-LAG 330-1 Subliming Tro-<<el Grade Material.
The sequential steps invol; d in 'nstall'ng this fiza barr'er design are described in the following paragraphs.
Installation oi the One Hour Ready Access'Fire Barrie Design 1.1.1 Cut a piece of material large enough to fora the bottom sect on from a
. one hour fire rated Prefabricated Panel. The width of the bottom section shall be equal to the sum of the base and both flanges, plus both sides of the cable tray. The length of the bottom section shall not exceed 6.5 feet, since longer sections are unwieldy and moze difficult to install.
3,.1.2 Fozm a rectangular shaped bottom section by making two (2) 90 degzee bends which provide for the side panels. The section shall be formed with the Stress Skin Side on the inside.
1.1.3 Cut a piece of materia3. large enough to form the top section from a one hou c' <<a ~p 9 ~rab<<g<<ate 5a 1 L gpth oc t4~ top section shall be equal to the base, plus both flanges of the tray, plus the thickness of each of the two (2) sides of the bottom rectangular section.
1.1.4 Mount the rectangular shaped bottom section on the cable tray using 18 ga. minimum stainless steel tie wires or 0.5" x 0.020" minimum stainless steel banding material as shown in Figures II-1, II-2 and II-3, following this page. The recommended maximum spacing between the tie wires shall not exceed 12 inches.
Attach the flat top section with the stress skin side on the inside to the installed bottom section using 18 ga. minimum stainless steel tie wire or 0.5" x 0.0 0" minimum banding material at a maximum recommended spacing of 12 inch intervals as shown in Figures II-4 and II-5.
1.1.6 Attach additional top and bottom sections to previously installed sections by butt )oining them together at their ends.
OR AS AÃ OPTION 1.1.7 Cut individual pieces having either butted or miter cut edges large enough to form the bottom, sides and top section from a one hour fire r'ated Prefabricated Panel.
1.1.8 Mount the bottom, side. and top pieces on the cable tray using 18 ga.
minimum stainless steel tie wire or 0.5" x 0.020" minimum stainless steel banding material. The recommended maximum spacing between the tie wires shall not exceed twelve (12) inches.
1.1.9 Attach additional top, side and bottom pieces to previously installed pieces by butr, Joining them together at their ends'.
1.1.10 Complete the installation by filling in the'edges and points with

SECTION VII THER~!0-LAG 330 PIRE BARRIER SYSTEM COATING APPLICATION TECHNIQUES 1.0 THERMO-LAG 351-2 PRIMER APPLICATION Prepare the surface of the steel entity for application of the THERMO-LAG 351-2 Primer by removing any dirt, scale, rust or other contaminants, using hand or mechanical cleaning methods. Never apply the primer directly over any hard or glassy painted surface without roughening the. surface in accordance with standard'painting practices.
1.2 .'!ake sure that the cleaned surface is compatible with the THER'!0-LAG 330-1 Subliming Material by making cross hatch adhesion tests as follows:
Cross Hatch Adhesion Test The prime" is cut.over an area approximately 4" by 4" in a square matrix, with each square being approximately 1/2" by 1/2". A high quality tape is applied diagonally to the square. Upon completion I
I I af the tape application, it is rubbed in firmly to assure good I 'I adhesion. With one complete perking motion, the tape is removed.
I ~
If more than 3 percent. of the Primer is removed fram the surface, the application is faulty. This test should be performed in areas I
which are deemed critical and in as many places as required by the specification. Upon completion of the Cross Hatch Adhesion Test, I
the test areas should be coated again with the THERMO-LAG 351-2 Primer I
by either brushing or light spraying.
,I Always apply a barrier coat of the THERMO-LAG 351-2 Primer over steel surfaces which have been p'reviously primed with a zinc based primer. All doubtful surfaces should be removed using mechanical cleaning methods.
~ ~, .~

Apply the Pr"=er -o "he properiy prepared steel surface ln <ne continuous coat using sprav equipment, brush or roller. The mini=urn acceptable dry Primer thickness should be 0.002 inches Vhich is normally achieved by applying a spread rate of circa 200 sq. ft.
per gallon.
1.3 Measure the Primer thickness using an approved magnetic (non-destructive) direct reading gauge.
1.4 'ake proper cross hatch adhesion tests on the primed surface to assure 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.
1.5 Co'at the primed steel surface area with the TF"-RMO-LAG 330-1 Subliming
.'material.:ce coating shall be applied in accordance w'th pro d res set out in Paragraph 2.0 of Section VT:, herein.

2.0 TH""Bi30-LAG 330-1 SUBLDfING MATERIAL - SPRAY APPLICATION 2~1 Apply the ;ciFB'lO-L'G 330-1 Suoliming Material over a properly prepared surface. 1wke sure that the surface to be coated is clean, dry, above 40F and free from scale, rust or other contaminants.
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 minimum dry film thickness of 0.500 inches is accomplished by applying three (3) wet coats of 0.255 inches. However, the thickness which can be safely applied in a single pass will depend on the temperature, hum"dity, and other factors that are best determined on the Jobsite.
2.3 Apply the material in smooth even passes, taking care to keep the spray gun fa.. pattern at a 90 degree angle wnenever possible.
Reaching <<ith a spray gun will cause the spray pattern to vary from the 90 degree angle and will result in a roughe" surface than normal.
2.4 Take freauent wet thickness measurements during the application using a non-destructive penetration measuring device to ensure that the coat'ng is be'ng appl'ed uniformly and at the 'requ'r d wet film thickness. .hese wet thickness checks shall be ~de every five (5) square feet or every two (2) running feet of coating surface area.
(Note: @hen taking measurements, allow for a shrinkage rate of circa 25Z between the wet and the desired dry film coating thickness.)
2.5 Remove excess build up of coating material at edges and )oints by brushing or rolling the surface with a'. damp sponge roller or a nylon bristle brush.
2.6 Spray edges of the substrate from each side to cause the material to wrap around the edge. If the edge coating is not completely closed, use a wet roller or trowel to seal the edge surface.
2.7 Remove all runs, sags, drips or other surface imperfections before the material cures, using wet sponge rollers, brushes or hand trowels.
3.0 THERMO-LAG 330-1 SUBLI-! 'ZG .'-4 ERODE. - TROl~'EL AP LICATION 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.
4.0 THERMO-LAG 330-660 BULK GRADE MATERIAL - TROWEL APPLICATION 4.1 Trowel the material to a uniform thickness using moderate pressure and avoid overworking. The trowel should be wetted with water when' s~ooth finish is requ'red.
5.0 THERMO-i 4G 350 TWO PART SPILL RESISTA.'tT TOPCOAT 5.1 Apply the THER.'!0-LAG 350 Two Part Spill Resistant .Tcocoat over .
the THER.'!0-LAG 330-1 Subliming Material (spray or trcwel grades) after allowing a minimum of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for the THERMO-LAG 330-1 terial to cure.
5.2 Apply the topcoat by brush, roller or spray. in multiple passes or criss/cross. technique at a spread rate of 50 sq. ft. per gallon.

- 7. 0 REPAXR PROCEDURES The repair of a damaged section in a THERMO-LAG 330 Fire Barrier is easily accomplished by cutting out and removing the damaged material, and then filling in the cut out section with new material.
7.1 The first step in this procedure is to remove the damaged and loose material using a kni=e and scraper. Care should be exerc'sed that the damaged material is cut back until. sound adhering material is reached.
7 The "..'ext step 's to uncercut the edges around the cut out section to for= a beveled edge. A3.1 foreign matter is then removed from the exposed substrate surface in the cut out sect'on.
7.3 The THERMO-LAG 330-1 Subliming Material or THERMO-LAG 330-1 Subliming Trowel Grade Material is sprayed or troweled into the cut out section.
If nccessary, several coats can be applied to achieve the desired film thickness. Care should be taken to allow for shrinkage of the repair patch by building up a slight dome shape on the surface of the patch.
8.0 CABLE REPLAC~ PROCEDURES The replacement of a cable in a THER'fO-LAG 330 Fire Barrier is accomplished by removing sections of the fire barrier, replacing the cable, and then reinstalling the sections.
8.1 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.
8.2 Next, the stainless steel tie wire or banding material is cut and the fire barrier section removed from the cable raceway.
8,3 After the defective cable has been replaced, the fire barrier sections are rainstalled, using l8 ga. minimum stainless steel tie wire or 0.3" x 0.'020" mini um sta'n'ess steel banding material. A coating of the T:=.EB.'lQ-UG 330-l, Subliming Tro<<e'rade .'faterial is then applied in the specified wet film thic'cness to the ecges and joints of the reinstalled sect'ons, using a trowel or stiff bristle brush, to fill in any uncoated areas.
9.0 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.
