INTRODUCTION

For compliance with lOCFR50, Appendix R at the'. C.Cook Nuclear Plant, tests were conducted on power and controlcables enclosed in a TSI, Inc. one-hour fire barrier system.The results of the test will be compared to computer-generateddata to determine the validity of the computer model on heatrun flow and cable ampacity.

OBJECTIVE

The test objective was to simulate as closely as possiblethe actual conditions of tray and conduit runs proposed for CookPlant and determine the final conductor temperature for the specifiedamperage and tray fill.

III. TEST METHOD

The generalized test method consisted of:

l. Installingcables'.

Attaching thermocouples.3. Enclosing the TSI fire barrier system.4. Applying the specified amperages.5. Maintaining a constant ambient temperature of

40oC.6. Monitoring the temperature rise and final conductor

temperature.

Test Setup

2.1 Raceway

2.1.1. Cable tray and conduit were supported approximately2'-6" above floor to allow for natural ventilation.

2.1.2. Raceway ends were sealed during the test withthermal insulating material to prevent heatloss through these areas.

Note:

This procedure could cause excessive heatingof the cables passing through the thermal seal;therefore, all temperature readings were takena minimum of 1'-0" from the thermal seal.

2.2 TSI One Hour Fire Barrier System

2.2.1. The tray envelope was constructed of the pre-fabricated panels, cut so as to fit as shownin the Appendix (see Figure Il).

2.2.2.

2.3

The conduits were encased in the prefabricatedsections.Thermocouples

2.3 ~ 1 ~ T-Type thermocouples were used to measure tempera-tures of the following:

A ~ Ambient airB.. Top and bottom of the fire barrier envelopeC. Air space in trayD. Conductors.

2. 3. 2.

2.3.3.

Thermocouples were installed on the inwardside of the conductor in a triplex arrangement(see Figure 2). A hole was bored in the insulationand the thermocouples were placed on the conductor.

Thermocouples were imbedded in Omegatherm 201high thermal conductivity paste.

2.3.4. Thermocouples were installed in a positionlocated on the cables in the center of thetray where:

A. Heat generation is greatest.B. Heat dissipation is the least (see

Figure 3).P5- C48LE-vo /Re.d oHz80//@7 'f3oF g3

2.3.5. The minimum number of thermocouples used tomeasure the conductor temperature was two (2)per cable circuit installed in the tray andfive (5) for single cables installed in theconduit.

2.4. Cables

2.4.1. Cables were positioned in the cable tray ina single layer in such a position that therewas a minimum spacing of 1/3 the diameter ofthe larger adjacent cable. Cables were thensecured with "Ty-Raos".

Test Procedure

3.1 Each test consisted of installing the cablesin the trav in one of six (6) configurationsas specified in the test request.

3.2 Once the proper setup was attained, cableswere subjected to a load of three phase,60 Hz sinusoidal current as specified in Section

3 ~ 3„ Ambient temperature was set to 400C.

3.4 ~ .emperature rise of the cables was recordedon an Esterline Angus llodel PD-2064 data acquisit-ion system at 4-hour intervals until the cabletemper atu res st abi 1 ized.

3.5. The voltage and amperage of each circuit wasmonitored periodically throughout the test.

~ DISCUSSION

Due to a limited supply of variable power sources, several circuitswere consolidated. In all cases, the loads were met or exceeded those thatwere originally requested.

As per the original request, conductors were placed in the cable trayin a single layer in such a position that there was a minimum spacing of1/3 the diameter of the larger adjacent cable. Although this probably isnot the best simulation of actual conditions, it was one criterion of thetest request. During Test 53, the amount of cables made it impossible tofollow this criterion. It was followed as closely as possible and the resultscan be viewed in the Appendix under "Photographs".

All results contained in this report were forwarded to W. F. Wilson,New York, immediately upon completion of the test. Any questions pertainingto the actual test results as compared to the computer-generated data shouldbe directed to him.

Calculation PS-CABLE-001, Rev. 0Verification Cont.

In addition to the verification checklist (Page 1), the following additional informationdocuments the verification effort for calculation PS-CABLE-001, Revision 0.

For the identified cable trays at Cook Plant, it was necessary to predict correction factorsfor fills greater than those described in IPCEA-P-46-426 (up to 6 horizontal cables) so the

appropriate conservative correction factor could be applied to the actual fillconfiguration.A mathematical model was developed which represents the correction factors identifiedin IPCEA-P-46-426. MATHCADwas used to calibrate this model with the results beingequal to the correction factors in the IPCEA standard and to calculate the correctionfactors for fillquantities greater than the IPCEA standard maximum value of6.

Per the calculation procedure 227200-STG-5400-02, ifa computer program is used therequirements of 800000-LTG-7100-02 shall be met. Per review of section 2.2 of800000-LTG-7100-02, software not identified for production purposes (e.g. one timecalculation) is exempt from requirements in 800000-LTG-5400-08 and 800000-LTG-7100-02. Calculation PS-CABLE-001, Revision 0, documents the review of theampacity derating for installed cables, for historical purposes, to closeout the Thermo-Lag issue. In the opinion of the independent verifier, this is a one time calculation whichis exempt from procedure 800000-LTG-5400-08 and 800000-LTG-7100-02 as explainedabove.

The followingminimum requirements, per 800000-LTG-7100-02, do apply to thissoftware. Validation of the sofbvare shall be performed and independently reviewed.Also the program listing, verification and independent review shall be treated as a QA .

record. Validation of the software willbe done by alternative hand calculation as shownin the followingpages. The program listing, verification with review willbe made a partof this calculation, which is a record. Quality Assurance (QA) was contacted and the useof this software for this calculation was discussed. QA concurred with this independentverifier's opinion to treat this use ofsoftware as a one time calculation.

The computer listing is a hard copy of the logic steps/commands ofhow the computerprogram operates (runs). The purpose of the program listing is to enable the computerprogram to be recreated and/or run at some future date. In the case ofMATHCAD,therereally is no official"program listing" because MATHCADis a mathematical "numbercruncher". Therefore, no computer listing is included in calculation PS-CABLE-001,Revision 0. However, attachment 2 is a copy of the input screen for MATHCAD. Thisinput screen identifies the version ofMATHCAD,mathematical model, and specificdirections to replicate the correction factors as documented in the calculation.

The MATHCADprogram was used to develop an equation to "predict" correction factorsfor fills>6 cables horizontaly. The mathematical model was generated using thefollowing data from IPCEA-P-46-426 table VII:

¹ CABLES ADJACENTCABLES(t)

DERATING

0.93

0.87

0.84

0.83

0.82

The equation MATHCADgenerated to "fit" these points is:

mf(t)= 0.8+0.129 e'

0.073 e

Where t is a number ofcables directly adjacent to the cable ofconcern.

The validation ofMATHCADwas verified by plugging in any of the number pair above.

mf(2)= 0.8+0.129 e + 0 073= 0.8 + 0.047 + 0.027= 0.874

mf(3)= 0.8+0.129 e <'"'">+0 073 '""'"= 0.8+ 0.028+ 0.016= 0.844

mf(5)= 0 8+0.129 e'

0 073= 0.8 + 0.010 + 0.006= 0.816

mf(12)= 0.8+0.129 '0 073

= 0.8+ 0.000+ 0.000= 0.8

mf(20)= 0.8+0.129 '0 073

= 0.8 + 0.000+ 0.000= 0.8

In section 4.0 of the calculation, the ampacity for 3TC ~tI 6 Al cable is adjusted for 130'C(short time rating) in accordance with IPCEA-P-46-426 equation 5 as indicated below:

I'= I 0 (Tc'-Ta)/ (Tc-Ta)*(228.1+Tc)/(228.1+Tc')Where I'= Ampacity @ 130'C

I= Open AirAmpacity @ 90'C= 69 AmpsTc'= Conductor Temperature 130'CTc = Conductor Temperature 90'C

I'=69 0 (130-40/ (90-40)~(228.1+90/(228.1+130)

I'=69 0 (90/ 50)*(318.1/(358.1)=87.25 Amps.

In attachment 3, Table 3 through 8 the actual watts are calculated using followingequation:

Actual watts = Z"3 n I R„Note: 3 is used for 3TC cable.
