1 0 68KQSR The purpose of this calculation is to determine or update ampacity values for power cables routed in St. Lucie Unit 1 and Unit 2 conduits wrapped with Thermo-Lag fire barrier systems as listed in previous calculations (Ref. 2.3). This document outlines the methodology used to determine power cable ampacity including derating factors. Wrapped conduit derating factors are determined for existing fire barriers and for upgraded systems.

Existing cable protection will be upgraded on certain conduits to maintain required levels of protection. The cables in the conduits have been evaluated to require protection because no redundant functions or alternate conduit routes exist to eliminate the need for protection (Ref, 2.76-2.88). By performing an evaluation with upgraded conduit wrap, cable ampacity margins may be verified to ensure adequate capabilities exist for providing power to affected electrical toads.

Revision 1 to this calculation adds a discussion of the operating heat loads (Watts per foot) for the wrapped cables and a comparison of the cables at St. Lucie plant to the cables tested at Omega Laboratories for Texas Utilities'omanche Peak Plant (Ref. 2,26) Heat load factors provide an

~

additional assurance that cables installed at St. Lucie are enveloped by the test configuration.

Cable manufacturers and IEEE gives ampacities for cables up to one three conductor (3/c) or triplex cable in a conduit in air. The cable ampacities are derated when the number of conductors in a conduit exceeds three (3). Cable ampacity is multiplied by the following correction factor (Ref. 2.104):

Total Number Ampacity of Conductors Correction Factor 3 1.00 4-6 0.80 7-9 0.70 3.10 Calculate derated ampacity (I') for each power cable.

4.0 4.1 Fire protection wrap used at St. Lucie station is the Thermal Science, Inc. (TSI) Thermo-lag Fire Barrier System. Typically, the half-round "clamshell" covers applied over conduits have a nominal thickness of 5/8" for one (1) hour ratings and one (1) inch for three (3) hour ratings.

4.2 The original design calculations for derating factors determined that Thermo-Lag barriers reduced ampacity by approximately 12%, however, for conservatism, a derating factor of 15% was selected for power cable sizing (Ref. 2.21).

4,,3 Control and instrumentation cables are not subject to ampacity limits due to the small levels of current used. Voltage drop in the control circuit is usually the limiting factor for cable design and normally requires the installation of larger cables to perform required functions.

4.4 The continuous device current load was used as a basis for this calculation. Momentary load requirements, i.e., those lasting less than 1 minute, are not considered. Loads of this duration are not sustained long enough to induce heat in the affected power cables. Abnormally high levels of current for devices are detected by protective devices and the component is designed to be separated from the power source before the condition damages the component or cable.

4.5 Fire protection barriers in St. Lucie Unit 1 and Unit 2 are installed on cable conduits and conduit boxes only. There are no cable trays wrapped with fire barriers at the St. Lucie station. However, sections of conduits 21001F-4" and 21001H-4" are routed in a "banked" configuration. There were no tested configurations for banked conduit runs; therefore, the ampacity correction factor for cable tray were used. The banked conduits are in a single plane and the conduit size of 4 inches is similar to the depth of cable tray used at St. Lucie. Using the cable tray derating factor gives a more conservative estimate of the current carrying margin for the affected cables in these conduits (21801W, 21801X, 21801Y and 21801Z).

4.6 This calculation applies to cables in protected conduits inside and outside containment of both St. Lucie units. The ambient temperature for cables inside containment is assumed to be 50'C. Outside of the containment buildings, ambient temperatures are assumed to be 40'C (104'F). Operating temperatures in the RAB are normally closer to 30'C; however, for conservatism, the higher temperature will be used.

4.7 Power cables utilized in St. Lucie'station are rated for operation at 90'C conductor temperature. The higher the insulation temperature rating, the greater the allowable ampacity for a given conductor size.

4.8 Conduits protected in St. Lucie Unit ¹1 use (3) hour barrier one (1) inch nominal thickness material. Conduits protected in St. Lucia Unit ¹2 may be protected with one (1) hour 5/8" nominal thickness material or three (3) hour one (1) inch nominal thickness material. This calculation assumes three (3) hour protection will be upgraded by using layers of Thermo-Lag 770-1 wrap and trowel grade materials. One (1) hour barriers will be upgraded with overlays of (1/4") nominal thickness curved sections of Thermo-Lag 330-1. These assumptions are based on currently available upgrade systems that are cost effective for use at St. Lucia.

L T CALCULATION,NO. - F - - 1 REV. 1 SHEET NO. ~4 4.0 N A 4.9 Conductor current values for 600 volt cables are based on IEEE standard values (Ref. 2.75) for conductors rated 600 to 5000 volts, 90'C (194'F) ambient temperature with no solar heating and 2 FT/s wind/ventilation.

4.10 Where load values are known in kilovolt-amperes (KVAs), the current is determined by; h C Ci:

=V I= V 1 amps (three phase AC) 3xV 4.11 The ampacity testing performed for Comanche Peak Plant was performed for conduits ranging in size from 3/4 inches to 5 inches. Conduits covered with Thermo-Lag 330-1 fire barriers at St. Lucie plant range from 1-1/2" to 5". The heat load (I'R loss) from each cable section is included in Tables 5.5a, 5.5b. 5 5.5c. These heat loads were compared to the tables/charts used by Turkey Point where heat loads were compared to the Omega Point Laboratory test for Texas Utilities Comanche Peak Plant (Ref. 2.20). From this it is concluded that the test samples utilized are representative of the configuration at St. Lucie.

4.12 There are'no installed cable tray sections at St. Lucie protected by Thermo-Lag fire barriers.

However, there is a large pull box installed in St. Lucie Unit 2 elevation (-) 0.50', box B2431-SA which was reviewed due to size. The box is a 42" x 42" x 12" enclosure used as a pullbox for the power cables to AFW pump 2A. The horizontal surface on the bottom of the enclosure is expected to be most affected by fires in the 12" box depth. Because the original test performed by TSI included a 12" cable tray section and the Comanche Peak test included a 24" cable tray section, the large enclosure in St. Lucie Unit 2 is considered bounded by the previous tests.

4.13 ln accordance with Reference 2.101, the thickness of the Thermo-Lag and the gaps within the Thermo-Lag, found during the inspection of the correctly installed configurations for'the Unit 1 8c 2 one hour and three hour barriers, were in accordance with the installation instructions of TSI. Therefore, the configuration of the Thermo-Lag barriers at St. Lucie are bounded by the TSI installation instructions.

4.14 FPL participated in a generic industry test program managed by the. Nuclear Energy Institute (NEI) which included verification of the chemical composition of Thermo-Lag material. As part of the NEI test program, a pyrolysis gas chromatographic analysis was used to qualitatively compare the organic constituents of various Thermo-Lag samples. St. Lucia provided (9) samples from installed and warehouse Thermo-Lag materials. All of the samples tested at NUCON Laboratory in Columbus, Ohio were found consistent in terms of chemical composition (Ref. 2.103). Results of the testing program were sent directly to the NRC by NEI letter dated October 3, 1995. Per Reference 2.102, the NRC stated that there was essentially no differences between the samples for different lots, areas of the country and the year the material was purchased.

5.0 5.1 The documents listed in Section 2.0 of this calculation were reviewed to identify the cables wrapped with Thermo-Lag which must be considered for ampacity derating factors.

6.2 Bills of Material were reviewed for cables identified in 5.1 to determine insulation voltage rating and intended generic use, i.e., power or control and tabulated in Table 5.1.

5.3 From information listed in documents of Section 2.0 and appropriate bills of material, Tables 5.2, 5.3 and 5.4 were generated to identify affected cables in wrapped conduits. These tables identify cable types, usage voltage class, insulation voltage rating, a description of the cable load for power cables and the number of current carrying conductors in each conduit.

5.4 Motor load kilowatt and current ratings vary in prior documents depending on base values used. For this calculation, current values for motors were determined from nameplate listings on referenced One-Line List drawings.

5.5 From this information and Section 2.0; Tables 5.5.a, 5.5.b. and 5.5.c were created.

L Al N HE CALCULATIONNO. 1 REV. 1 SHEET NO. ~

6.0 REHEAR The results shown in Tables 5.5.a., 5.5.b. and 5.5.c. indicate that when using newer ampacity correction factor (ACF) as determined in the Turkey Point calculation, PTN-BFJM-96-005, for upgraded Thermo-Lag fire barrier installations, sufficient margin exists between operating cable loads and cable cuirent carrying capacity (ampacity).

This calculation revisited prior calculations-, and Appendix R and RG 1.75 documents to eliminate the conservatism that existed in the earlier calculations when considering the load on a specific cable.

Ampacity values used in this calculation are loads that exist longer than 60 seconds; i.e., do not include the battery or valve loads during the first minute which are reduce significantly for longer operation.

As listed above, the smallest margin for St. Lucie Unit No. 1 Thermo-Lag (3) hour upgraded wrapped conduits is ~1 4 7 . This margin is for the 125 volt DC power cables from Battery lA to Battery Test Panel lA for supplying 125 volt DC bus lA. Loads on these cables are steady state loads after the first minute of operation when the cable is subjected to continuous loads. Loads on the battery cable are higher in the first minute due to cycling of valves and other motors.

The smallest Unit No. 2 margin for (3) hour upgraded wrapped conduits is ~~1+ for the 4160 volt power feeder cables to Station Services Transformers 2B2/2B5. This value contains some conservatism since it assumes 100%

conduits in St. Lucie Unit 2, the smallest margin is ~~

transformer loading. For (1) hour upgraded wrapped for the 4160 volt feed to Station Services Transformer 2A5. This value includes conservatism, similar to the margin to Transformers 2B2/2B5, since it assumes 1004 transformer loading.

The original calculations for cable derating in St.'Lucie Unit 1 and Unit 2 used a value considered conservative at 154. This calculation has determined that acceptable power cable margins exist for installed cables in St. Lucie Plant Unit 1 and Unit 2 when using derating values of 114 for (1) hour fire barriers and 204 for (3) hour fire barriers assuming the installation of Thermo-Lag 330-1 and Thermo-Lag 770-1 upgrade fire barrier systems.

A revision to the cables in conduits 21001F-4" and 21001H-4" was included in Revision 1 to this calculation. These conduits were found to be in a banked configuration for part of their route; For conservatism, the ampacity derating factor for cable trays was applied to these conduit sections. The r'esultant ampacity margin changed from 91.534 to 65.204 using the cable tray derating factor of 314. Revision 1 also concluded that installed conduit configurations at St Lucie plant are bounded by test performed at Omega laboratories for Texas Utilities'omanche Peak Nuclear Plant.

Analysis involved weighing 1-3 mgs. of sample in a quartt tube and piaceaent of the tube in the platinum coB cleaxat of the probe. The probe is then placed in the interhce and pyroiysed ballistically far 2 sexxxh. Pyrolytic products are then swept by the cmrier gas onto the fueed sBica ancillary column where they are separated and detected with a MSD. 'nd pyrolysis conditions are Quota in Table 1. Prior to each analysis, the column is heated to 250'C to elute any voiatlles which were not entrained in the polymer.
