i sa/r/r x "0 V-llo l- ? ?o - off 1.0 Problem Statement Power cable ampacity at TMI-l is derated for use in cable trays in accordance with IPCEA P-46-426 (Ref. 3.6) as reported in the TMI-I Final Safety Analysis Report (FSAR), Ref. 3.1I section 8.2.2.11. Power cables whose tray is wrapped with Electrical Raceway Fire Barrier Systems (ERFBS) to meet 10CFR50 Appendix R (Ref. 3.12) requirements require an additional derating factor. At TMI-1, Thermal Science Inc. (TSI) Thermo-lag 330-1 one-hour rated ERFBS is used for cable trays (Ref. 3.13). The Gilbert /Conunonwealth Cable Sizing Criteria for Cycle 6 Routing (Ref. 3.14) used ERFBS derating factors provided by TSI. These factors have been revised by testing performed for nuclear plants at Texas Utilities (TU) whose ERFBS configurations bound configurations at TMI-l (Ref. 3.13). The problem is to calculate ampacity of power cables in trays protected by ERFBS, revising the ERFBS derating factor from 13% to 32% and compare the revised ampacity against the expected load currents. 1 t 0 9610280224 961022 PDR ADOCK 05000289 F PDR

/ s /r/s / oa 1 The ampacity of power cables in trays protected by ERFBS is calculated, revising the ERFBS derating factor from 13% to 32% and the revised ampacity is compared against the expected load currents. l For 32 out of 35 cables the maximum expected load current does not exceed the revised ampacity. There are three (3) cables, CG83, LP2, and LP6, out of 35 for which the maximum expected load current may slightly exceed the revised ampacity when calculated using the IPCEA P-46-426 (Ref. 3.6) methodology. These circuits CG83, LP2, and LP6 are routed in tray 590 along with circuits CGI1 and CQ43. The NEC (Ref. 3.7) is used to provide a closer evaluation of these circuits which takes credit for the actual physical configuration. ] In conclusion, all 35 circuits in this calculation are acceptably sized with respect to ampacity even with increased deratine due to Thermo-lan fire barriers. No changes are required at this time except for documentation. Documentation will be reviewed including but not limited to the FSAR (Ref. 3.11), the FHAR (Ref. 3.1), arid ES-023 (Ref. 3.3) and any necessary changes will be incorporated. 1 Because this analysis shows that the revised ampacity of cables installed in trays protected by one-hour fire barriers is acceptable, it follows from assumption 4.2 that the revised ampacity of cables installed in conduits protected by one-hour fire barriers is acceptable as well. With the IPCEA (Ref. 3.6) methodology the worst case was LP2 where the maximum expected current exceeded the ampacity by 3%. From Table 2 the cables in conduits protected by one hour fire barriers have 14% to 15% higher ampacity than cables in trays protected by one hour fire barriers. Thus, it is inferred t. hat cables in conduits that have been sized using the IPCEA (Ref. 3.6) methodology are acceptably sized with respect to ampacity. i 9

These words are adapted from the FSAR (Ref. 3.11) section 8.2.2.11 b. fifth sentence. However, in cases where power cables are routed with control power cables, then the control power cables are considered because they can affect each others' ampacity. 4.2 At TMI-l there are no 480 VAC or 4160 VAC power circuits that are protected by three-hour rated fire barriers as per the FHAR (Ref. 3.1). For 4160 VAC power circuits, the one-hour rated fire barriers are ins:alled over cable trays or over cables that are in cable trays. For 480 VAC power circuits, fire bar:iers are installed over cable trays or over conduit Testing performed for Texas Utilities (TU) showed one-hour fire barrier derating factors of 31.6% for cable trays and 10.7% maximum'for conduit (Ref. 3.8). The one-hour fire barrier configuration at TU plants bounds the one-hour fire barrier configuration at TMI-l (Ref. 3.13). Conduit is not included in this calculation because cable tray derating associated with the addition of Thermo-lag is considered the bounding case. Table 2 shows the comparison between cable trays and conduit.

- 8 41 28 36 32 350 MCM 285 194 253 225 Values in columns two and four of Table 2 are taken from Ref. 3.14 which is based on Ref. 3.6 for a 90 C conductor rating operating in a 40 C ambient when installed with a total of 7 to 24 current canying conductors inclusive. Columns 3 and 5 are calculated by multiplying the respective values in columns 2 and 4 by 0.680 and 0.890 representing derating factors of 32.0% and 11.0% respectively. When comparing columns 3 and 5 it can be seen that the ampacity for cables routed in tray protected by a one-hour fire barrier is significantly less than that for cables in conduit. Thus, the analysis of ampacity of cables installed in trays protected by one-hour fire barriers is bounding when compared to that for cables in conduit.
4.3 All original power cables are manufactured by Kerite (Ref. 3.17) except as noted in Table 3. This is reasonable since our research found no other vendor, except as noted, and the free air ampacity values given by Kerite are comparable to those given by Ref. 3.6 or Ref. 3.7. 4.4 Unless otherwise noted all cables are assumed to be installed without maintained spacing. This configuration is more conservative than with maintained spacing or installation in accordance with NEC (Ref. 3.7) Article 318-9. 4.5 For cables MB11 and MCl2 the ambient temperature in the winter is less than 90 F (32.2 C). The winter ambient is correlated with the heavy heating loads in the winter. The ambient ofless than 90 F

For cables manufactured by those other than Kerite (see Table 3 for manufacturers other than Kerite), the table on page 309 of Ref. 3.6 for i KV 90 C rated conductor temperature in air at 40 C is used for Column 4. 7.5 Column 5 shows the ampacity in amperes corrected for ambient temperatures less than 40 C given in Table 3. Ref. 3.6 Equation SA is used to correct for ambient temperatures other than 40 C. l' = Id(Tc'-Ta'-D:ltaTd')/(Tc-Ta - DeltaTd) in Amperes where: I'=ampacity at new ambient temperature Ta' and new conductor temperature Tc'in Amperes I=ampacity at old ambient temperature Ta and old conductor temperature Tc in Amperes Tc'=new conductor temperature in C Tc=old conductor temperature in C Ta'=new ambient temperature in C Ta=old ambient temperature in C DeltaTd'=new dielectric loss temperature rise in *C DeltaTd=old dielectric loss temperature rise in C From page 309 of Ref. 3.6, DeltaTd' = DeltaTd = 0 C for 1 KV and lower cables and <0 30 C (negligible) for i KV to 5 KV cables. Also, Tc' = Tc = 90 C and Ta = 40 C. The maximum design ambient temperatures for the control building from Table 3 is 95 F (35.0 C). Plugging in the values for the Control Building: f = IJ(90-35.0-0)/(90-40-0) = I(1.05) in Amperes Thus the free air ampacity values in Column 4 for the Control Building are multiplied by the above correction factors for ambient temperatures less than 40 *C to obtain the values in Column 5. For circuits MBI1 and MCl2 the ampacity are calculated for summer and winter operation since these cables carry a significant heating load. The ambient temperature given in Table 3 is for summer. During winter the ambient temperature in the Auxiliary Building is not expected to be greater than 90

Likewise, tray T-54-28 is not listed since only one cable passes though that tray and the same cable passes through tray 590. The tray containing the higher number of cables is used to set the ampacity of cables passing through. 7.7 Column 7 shows the ampacity derated to account for TSI one-hour fire wrap. Since configurations at TU bound Thermo-lag configurations at TMI-1, the testing performed for these utilities is used for establish a conservative derating for Thermo-lag. Ref. 3.8 provides a value of 31.6%. We will use 32% l derating or a factor of 0.68 for conservatism.

This evaluation shows that at the low end of the normal grid voltage operating range the motor load currents are less than the ampacity for the associated cable for NS-P-l l IB and NS-P-lC. For NS-P-1 A the degraded grid load current may exceed the derated ampacity for the associated cable by approximately 1% of the derated ampacity. A closer evaluation of this cable's revised ampacity in accordance with the NEC (Ref 3.7) is given at the end of this section. J Circuits CG83 and CH61 are for pumps IC-P-1 A and IB, during normal operation one of two pumps is in operation. The degraded grid currents are shown in brackets and come from Ref. 3.9.1. For IC-P-1 A the degraded grid current may exceed the derated ampacity by about 2% of the derated ampacity. A closer evaluation of this cable's revised ampacity in accordance with the NEC (Ref. 3.7) is given at the end of this section. Circuit CQ43 ampacity is generally neglected per FSAR (Ref 3.11) since operation of motor 9perated valves is infrequent when compared to operation of continuous duty motors. However, for conservatism it is included in this calculation. Circuit LP2 for DC-P-I A is loaded to the derated ampacity of the cable. At 232 KV the load current for this pump is 106 amps (ref. 3.9.6). DC-P-1 A is shutdown during normal plant operation and mns for periodic testing and when the plant is shutdown. This evaluation shows that at the low end of the normal grid voltage operating range the degraded grid load current the ampacity for the associated cable may exceed the derated ampacity by about 3% of the derated ampacity. A closer evaluation of this cable's revised ampacity in accordance with the NEC (Ref 3.7)is given at the end of this section. Circuits MEl and ME2 are parallel circuits for the IB Diesel Generator. The diesel generator is loaded for periodic testing and LOOP events only. The diesel output of 470 amps is split between the circui (235 amps per circuit). Circuit ME4 for EF-P-2B is de-energized during normal plant operation. EF-P-2B runs only for periodic testing. Circuits MA9 and MB9 for SR-P-3 A & B Post Cooling Tower pumps are normally de-energized. During the past year the Post Cooling Tower was in service 22% of the time.

Multiplying the fullload current by 1.25 to account for service factor we get 66.1 A. Circuit MBII power feeder to the IH Bus and circuit MCl2 pow:r feeder to the IM Bus are normally lightly loaded, except during cold weather when they can be loaded to beyond the cable derated ampacity at 40 C. The heavy loading is due to heating load during cold weather when the ambien temperature is less than 90 F or 32.2 C.

For MBI1, the load of <70 amps is based on a 4 KV feeder breaker ammeter reading obtained on 9/03/96 with the plant at 100% power. The IH Bus and IG Bus are supplied through a shared breaker therefore the measured load is the total load for l'oth buses. Load of 176 amps is a calculated value based on cold weather space heating load (see Appendix 8.1). For MBl3, the load of <10 amps is based on a 4 KV feeder Breder ammeter reading obtained on 9/03/96 with the plant at 100% power. Load of 56 amps is a cah:ated value based on operation of the Post Cooling Tower (see Appendix 8.1). For MCl2, the load of <50 amps is based on a 4 KV feeder breaker ammeter reading obtained on 9/03/96 with the plant at 100% power. The IM and IL Buses are supplied through a shared breaker therefore the measured load is the totallor.d for both buses. Load of 178 amps is a calculated value based on cold weather space heating load (see Appendix 8.1). Circuit ME6 for DH-P-1B is normally de-energized, DH-P-1B is a standby pump for Low Pressure Injection. It operates for periodic testing and when the plant is shutdown. Circuit ME7 for MU-P-lC is normally de-energized. MU-P-lC is a standby pump for High Pressure Injection and is normally operated for periodic testing only.

Thus, for 32 out of 35 cables the maximum expected load current does not exceed the revised ampacit There are three cables, CG83, LP2, and LP6, for which the maximum expected load current may slightly exceed the revised ampacity when using the methodology given in IPCEA P-46-426 (Ref. 3.6). These th circuits are routed in tray 590 along with CGI1 and CQ43. The NEC (Ref. 3.7)is used to provide a closer evaluation which takes credit for the physical configuration. From a walkdown on 10/3/95, tray 590 is a 12" wide and 6" deep tray. The cables are arranged in one la fastened to the tray with tie-wraps in accordance with the NEC (Ref. 3.7) Article 318-9(a)(3). The sum cross sectional areas of cables smaller than 4/0 using diameters from Table 3 is: A = nr = (3.14)(l.08/2)2 = (3.14)(0.540)2 = (3.14)(0.292) = 0.917 in: 2 CG11: A = nr = (3.14)(l.81/2)2 = (3.14)(0.905)2 = (3.14)(0.819) = 2.57 in2 2 CG83: A = nr = (3.14)(l.08/2)2 = (3.14)(0.540)2 = (3.14)(0.292) = 0.917 in 2 2 CQ43: A = nr = (3.14)(l.91/2)2 = (3.14)(0.955)2 = (3.14)(0.912) = 2.86 in 2 2 LP2: IA = Sum of cross sectional areas for cables smaller than 4/0 = 7.26 in 2 Table 318-9 Column 2 of the NEC (Ref. 3.7), for a 12 inch tray, requires that IA $ 14 - (1.2Sd), whe the sum of all diameters, in inches, of all Nos. 4/0 and larger multiconductor cables in the same the smaller cables. For tray 590 there is only one cable that is 4/0 or larger and thus: 14 - (1.2Sd) = 14 - [(1.2)(2.16)] = 14 - 2.6 = 11 in 2 Since 7.26 is less than or equal to 11, the cables in tray 590 are installed in accordance with the Article 318-9. Therefore, in accordance with Article 318-11(a) we can use table 310-16 to account for ampacity derating due to installation in tray. The column for 90 C with correction in accord same Table 310-16 for ambient of 40 C by multiplying 0.910 gives: AWG 10: 40(0.910) = 36 A AWG 1/0: 170(0.910) = 155 A AWG 2/0: 195(0.910) = 177 A AWG 4/0: 260(0.910) = 237 A Taking the additional derating due to Thermo-Lag, the revised ampacity for circuits in tray 5 methodology in the NEC (Ref. 3.7) becomes: CG11:(36)(0.680) = 24 A CG83: (155)(0.680) = 105 A CQ43:(36)(0.680) = 24 A LP2: (195)(0.680) = 133 A LP6:(237)(0.680) = 161 A

GIIM-?7s-E4-20 -sjg 01v. o l FPtn+ctyan.t PV-A I on i 1 IH & IM 480V Bus Heating 14ad and Load Factor Detennisation l Load measurements for the IH & IM 480V Buses during cold weather are not available. During moderate weather conditions these Buses are lightly loaded since the large space heating load connected to the Buses, (IH Bus - 1112 KW { and IM Bus - 1128 KW) is not energized. To reasonably calculate the impact of the heating load connected to these buscs, i the difference in load for the upstream 4160V bus during cold and moderate weather was evaluated. The IH Bus is powered from the IB 4160V Turbine Plant Bus and the IM Bus is powered from the IC 4160V Turbine Plant Bus. The total heating load connected to the IB Bus is the summation of the heating load connected to the IF and lH 480 V Buses. i The total heating load evaluated fro the IC Bus is the summation of the heating load connected to the IK and IM Buses. (Reference IH, IM, and IU Bus calculated Load Section). The MVA loading for the Balance of Plant (BOP) 4160V Buses (I A, IB & IC 4160V Turbine Plant Buses), Reference Drawing E-206-021(ref. Al.8) is monitored weekly. To determine a loading factor for heating loads, the difference in BOP Bus loading for the lowest ambient temperature day monitored was compared to a typical warm day monitored. DATE BUS MVA Loading 1/21/94 (ambient temp -16 'F) IB 4160V Turbine Plant 5.25 MVA 7/25/94 IB 4160V Turbine Plant 4.32 MVA AMVA = 0.93 MVA l/16/94 (ambient temp -16 'F) IC 4160VTurtune Plant 10.15 MVA 7/5/94 1C 4160V Turbine Plant 8.47 MVA AMVA = 1.68 MVA The total connected heating load for the IB 4160V Turbine Plant Bus is 1142.5 KW and the total connected heating load for the IC 4160V Turbine Plant Bus is 2328.4 KW. The difference in the IB and IC bus loading between externally cold day and typical summer day,932 KVA difference in load for the IB Bus and 1680 KVA difference in load for the IC Bus can be attributed to operation of the connected heating load. Using this assumption a load factor for the heatmg load connected to each Bus can be determined by dividing this j seasonal difference in Bus loading by the connected heating load to each Bus. i i Bus Seasonal Loadmg Total Connected Heating Heating Load Factor Difference Load IB 4160V Turbine Plant 930 KVA 1142.5 KW 0.81 Bus IC 4160V Turbine Plant 1,680 KVA 2328.4 KW 0.73 I Bus i The above factors are used to determine the calculated cold weather loading for the IH and IM 480V Buses.

However, for two-fan operation, the exhaust f an AH-E-7B is operating at the critical point of the With & slight increase in the system static fan performance curve. pressure, AH-E-7B fan will definitely be operating in a stall condition. Therefore, in order to prevent AH-E-78 fan from operating in a stall condition (in a two-fan operation), it is recommended that the Operating Procedures 1104-ISA and 1102,-14 be revised to provide instructions that during the Reactor Building purging and venting operation, the AH-0-82 makeup damper shall be fully open and AH-0-73 and 86, makeup dampers to Aux. and FHB exhaust f ans, shall be fully closed. This will increase the exhaust Increasing the exhaust flow of flow rates of the RB purge exhaust fans. these fans will move the operating point of each fan to the right of the fan performance curve and prevent the AH-E-7B fan (in a two-fan operation) from operating in a stall condition. ~ If you have any further questions, please call me on Ext. 2402 in Parsippany. arin Engineer, Mechanical Systems LOC:fg Attachments Director, Engineering & Design (D.

Discussion Due to the system configuration and location of the pitot tube sensing element of FR148A, the air flow reading taken from FR148A (FT148A) is unreliable. The air flow indication of FR148A (FT148A) will depend upon the fan line-up. Different fan line-up will create a different velocity profile in the discharge plenum where the pitot tube sensing element is located. AH-E-7A Fan operating alone will create a different velocity profile than AH-E-78 operating alone and definitely different velocity profile when both fans are operating. Based on this, the air flow read from FR-148A (FT-148A) will not be considered in this evaluation.. Note that if this exhaust flow rate is considered correct, the exhaust' fans (AH-E-7A & 78) are always operating in a I stall condition in any mode of operation. The reason for not considering the measured exhaust to the stack (reading from FR148A) is further illustrated in the following discussions of different fan line up. A. One Fan Operation of AH-E-7A Exhaust Fan: Based on the Fan Delta P of 8.7" W. G. and 9.0" W.G., the exhaust flow from the Fan performance curve is approximately 25000 CFM. The power requirement at this flow is 56 BHP (max HP requirement is 59 BHP as indicated in the BHP curve). Based on the measured motor current,.the BHP of the operating fan is 45.5 BHP and when this is plotted in the HP-curve, the exhaust flow is 29000 CFM approximately Both these flows when plotted in the Fan Performance curves show that the AH-E-7A fan is not operating in a stall condition with AH-0-82 operable (open). This also indicates that the exhaust flow of 17500 CFM as read from FR148A (FT148A) does not reflect the actual flow rate. 4330d

(measured across the fan), when plotted against the fan performance curve, intersects the SP curve at three (3) points which provided 3 different exhaust flows as indicated in Item II.B above (11800, 15200 & 21000). However, the fan Delta P of 10.32" W. G. (suction + Oischarge Press) indicates an air flow of 23600 CFM at 57 BHP. Comparison of 23600 CFM to the 3 air flows provided by the fan Delta P of 12.1" W.G., the 23600 CFM is closer to 21000 CFM. The HP requirement at 21000 CFM is 58 BHP. The exhaust flow can be verified further by the motor current reading of 62.7 Amps. At 62.7 Amps, the BHP of tne operating fan is 54.2 BHP and wnen this is plotted against tne HP-curve, three exhaust flows 9000,16600 and 26000 CFM are obtained. Of tne three At 21000 exhausts, 26000 CFM is closer to 21000 CFM and 22600 CFM. This CFM, the AH-E-78 fan is not operating in a stall conoition. flow indicates also that the exhaust of 15000 CFM as read from FR148A (FT-148A) does not reflect tne actual flow rate. C. Two Fan Operation From f an performance curve and based on the measured Delta P across the f an (10.0" W. G. for AH-E-7A and 13.1" W. G. for AH-E-78) the exhaust flow for'AH-E-7A is 24000 CFM and for AH-E-78 (13.1" W. G. intersects the curve at two points), exhaust flows of 10600 CFM and 18000 CFM are obtained. The BHP requirements of the fans at these On the air flows are 57 BHP for AH-E-7A and 51 and 56 for AH-E-78. otner hand, if fan Delta P is taken by adding the fan suction press and the fan discharge press, the exhaust for AH-E-7A (at 10.53" W. G.) and AH-E-78 (at 10.5" W. G.) is 23200 CFM with HP requirements Comparison of the exhaust airflow and bhp requirement of 58 bhp. of each unit indicates that the exhaust and bhp of AH-E-7A at 10.0" This indicates W. G. and 10.53" W. G. are approximately the same. that fan AH-E-7A is exhausting approximately 23000 CFM and tnat tne fan is not operating in a stall condition. However, the exhaust flow rate anc hp requirement of AH-E-78 at-The exhaust 13.1" W. G. and at10.5" W. G. are very much oifferent. flow rate'at 13.1" W. G. (which intersect the curve at two points) are 10600 CFM and 18000 CFM as compared to tne exhaust flow rate of 23200 CFM at 10.5" W. G. At 18000 CFM, the fan is operating at the In order to determine critical point of the fan performance curve. which exhaust flow rate is correct for AH-E-7B fan, tne Hp requirement of 55 BHP (calculated from the motor current reading of 63.5 amps) is compared witn the power requirement of 56 BHP (at e 9 4330d
c-not--776 -e %* - oI8 gy, c> APf,85 jyat 9 # 9 Evaluation of Test Per STP 141/14 - Page 7. 18000 CFM) and 58 BHP (at 23200 CFM). Tne comparison indicates that the calculated 55 BHP is closer to 56 DHP (at 18000 CFM). W is verifies and indicates that the exhaust of AH-E-78 is close to 8000 CFM and the fan (AHE-78) is operating at the. critical point of the curve. With a slight increase in the system resistance, AH-E-78 fan can be operating in a stall condition. Based on the above flow rates, the total exhaust to the stack is 18000 (for AH-E-78) plus 23000 CFM (for AH-E-7A) = 41000 CFM. This indicates that the exhaust flow of 25000 CFM as read from FR148A (FT148A) does not reflect the actual flow rate. IV.
== Conclusion:== For a single fan operation, either AH-E-7A or AH-E-7B exhaust fan is not operating in a stall condition with AH-D-82 make-up damper operable (open). At For two-fan operation, the exhaust of AH-E-7A fan is 23000 CFM. this flow the fan is not operating in a stall condition. However, the exhaust capacity of AH-E-7B fan is only 18000 CFM. At this flow, the fan is operating at the critical point of the pressure curve as indicated in the attached fan performance curve. With a slight increase in the make-up air system resistance, AH-E-78 will cefinitely be operating in a stall condition. These exhaust flows, however, are based on the make-up aamper partially closed as indicated in tne notes of Item I above. Opening tne make-up damper fully will increase the comDined exhaust flow and move the operating point of the fan 'B' to the right of the fan performance curve (away from the stall operation). Therefore, for two fan operation, the make-up air damper AH-0-82 must be fully open in order to prevent stall operation of AH-E-78 exnaust fan. V. Recommendation: Dased on the critical condition of one fan in parallel operation (two fan operation) and in order to prevent one fan from oper.ating in a stall condition, it is recommended that the Operating Procedures 1104-15A and 1102-14 be revised to provice instructions tnat during Reactor Building purging and venting operation, AH-D-82 make-up damper shall be fully open and AH-D-73 and 86 make-up dampers to Aux. and FHB This will increase the exhaust exhaust fans shall be fully closed. flow rates of RB purge exhaust fans. Increasing the exhaust flow of each fan will prevent AH-E-7B fan (in a two-fan operation) from operating in a stall condition. 433t,d J

Revision 2 is to remove the last sentence in the last Paragraph ofItest A. Distribution is only necessary to R. Benset. The purpose of this memo is to provide a comparison ofinstalled Thermo-Lag configurations at TMI with those tested by Texas Utilities (TU) for Comanche Peak and those tested by TVA to determine Thermo L.ag ampacity derating factors. l The above Reference 1 yielded ampacity derating values for one hour fire rated conduit, cable tray and air drop fire barriers. TMI uses Thermo-Lag on conduit air drops and cable tray. TMI uses one hour and three hour rated fire barrier configurations. For three hour rated conduit and cable tray configurations, companson is made with testing performed by TVA as documented in the above Reference 2. The latest NRC letter of July 5,19% requires responses which may lead to the need to establish derating margins for each circuit currently protected with Thermo-Lag. In order to do so, we must be able to W w that ThG Thermo-Lag fire barrier construction is bounded by FFB443WOU2RD T1 DCT-07-1996 13:59 7883 P.02

Note that TU did not test the desting effect around condulets. The diferences between TMI aad TU con 6pations are in the thickness of the TSI for conduits up to 2" diameter Because the TU configurations used.75" of TSI vs.5" at TMI, the additional insulating effect of the TU configurations should result in the TU test bounding the TM1 configurations. The results of testing on the 5" diameter conduit should be comparable with TM1 configurations ranging ftom 2.5 to 5" as they are the same with the following exception. The presence of the topcoat on the TU configurations is the one common diderence between TU and TMI configurations. However, the presence of the topcoat should tend to result in higher derating values. It is therefore reasonable to apply derating values obtained in the TU tests for conduit configurations at TML NOTE: In discussing the test results with TU, the NRC accepted the resulta for applicanna against instaBed TU configurations; however, NRC required TU to add an additional 6% derating over the 11% 1 used for existing conduit con 6gurations for any new cMn=ations TU installs. B l-Hour Barriers-Air Drops (TU) In comparing TMI and TU configurations, a r,pecific comparison is not documented here as in the case of the 1-Hour Barriam for conduit There is a difference in the two contigurations which should be overriding in establishing that the TU tests bound TMI conftgurations. TU's configurations use 3 layers of TSI flexi-blanket material while TMI configurations use 2 layers of TSI flexiblanket material. Raw upon this, I j believe the TU test data on air drops will bound the TMI configurations. C. 3-Hour Barriers-Conduit (TVA) TMI LY.A

- a 75" conduit protected by three-hour baniers. However, we need not pursue derating factors for this size banier since the.75" application is protecting a control circuit for which derstmg caused tiy Thenno. Lag is not a concem.
The differences between the TMI and TVA codcurebiw are in the upgrade employed by TVA. Because the TVA con 6 urations used addnional mats and trowel grade material, the 3 additional insulating effect of the TVA configurations should result in the TVA test Wadas the TMI configurations. Note that as with the TU con 83urations, the presence or lack of an air gap is considered "Not Applicable" for 3-hour conduit configurations because the TVA 3-hour barriers were applied around the conduits with no pre buttering of the inside surface of the TSI The barrier is not in uniform contact with the conduit in both the TM' u TVA 3-hour conduit banier cases. Therefore, this aspect of TVA construction can t~ considered representative of TMt construction Note that TVA test results in Table 13 of the above Refenace 2 are expressed in tenns of a correcuon fhetor, not pucent dorating factor. Cable tiny testing results are more varied than conduit. A combination of Bre barrier con 6gw ations from TVA and TU is discussed as follows: D. One-hour barriers - Cable Tray (Note that test results are not size dependent per Reference 2). In the TU test which was perfonned for a one-hour barrier configuration, on a 4x24 inch tray, the TU banier design utihzes a 1/2 inch thick layer of the Thermo-Lag 330-1 penals with various upgrades that ultimately increase the panel thickness to varying degrees such that the thickness is approximately 5/8". The cable mass consisted of 12631G6 AWG 600 veh copper cables armaged in four layers. The TU correction factor ACF (wrapped amps / baseline amps) is conservative for use at TMI as TMI @bs t/2 inch thick Thermo-lag 330-1 panels. Themdbre, the IU resuhs are bounding when consderms the TU fire barner configuration for cable tray have inherently higher insulating properties due to thicker Thermo-Lag panels, E. Three Hour Barriers - Cable Tray Three hour banier configurations consisted of 1 1/4 inch Thermo-Lag 330-1 panels The configuration added extemal stress skin and additional trowel grade material Additionally, the cordigurations were augmented with layers ofThermo-Lag 770-1 mats at 3/8 inch thick each. The TVA configurations clearly bound TMI cable tray fire barrier configurations with respect to ampacity derating as the insulating effect of the addinonal TVA matenal should resuh in higher derating factors. rrsuswcezatvu DCT-07-1996 14:00 78g3 P.05

To summarize, I believe it is reasonable to apply ampacity test results from TU and TVA for those configurations discussed above. The TU and TVA banier construction bounds TMI configurations with respect to ampacity testing. Please call ifyou have any questions. i F. P. Barbieri Extension 7358 j FPBlamd cc. D. J.
