IV PURPOSE OF CALCULATION:

Concems have arisen in the industry with the empacity deratins of cables that are located in conduit which is insulated with Thermo-Lag 330-1 fire wrap. This calculation is being performed to address the issue of ampacity derating for conduit insulated with Thermo-Lag associated with IEEE-384 and 10 CFR 50 Appendix R.

This calculation will determine the ampacity margins of the cables inside the applicable conduits. For the purpose of this calculation, ampacity margin is the percentage of extra cable empacity while the cable is loaded at the continuous value.

The ampacity margin will not include any affects of the Thermo-Lag.

The ampacity margins will be compared to empacity dorating factors for Thermo-Lag which are listed in calculation XX-E-008 Revision O. The ampacity margins will also be compared to test results from Tennessee Valley Authority (TVA) and Texas Utilities (TU). It is expected that the test results of TVA and TU will be utilized by NUMARC for industry ampacity dorating criteria.

V DESIGNINPUTS. ASSUMPTIONS. AND METHODOLOGY:

The design inputs, assumptions, and methodology have been based on the concept of ampacity derating. Ampacity derating is performed as to not degrade the life of the cable. The affect of improper amoscity derating does not result in an immediate failure of the cable under normal conditions; instead, the life of the cable will be decreased exponentially due to the temperature of the insulation being higher than rated.

The ampacity margins determined from this calculation will be based on nominal system voltages. The maximum system voltage does not exist on the system for extended periods. The nominal voltage will be considered an average voltage value of the system for the I!1stime of the cables. Furthermore, a general assumption for a high voltage is not conservative for constant KVA devices.

This calculation addresses all conduit applications as identified in Attachment 1. This list of Thermo-Lag applications was gathered from design documents and field walkdowns. All conduits with a service level which designates instrumentation and control cables were removed from the detailed evaluation. These cables do not carry a significant current and do not warrant a detailed investigation. Also, the Thermo-Lag applications which only employ a 6 inch or less fire wrap are eliminated from the evaluation due to the short length. It is assumed that negligible temperature rise will occur and conservatism is built into the ampacity of cables which will envelope this situation.

All power service level conduits will be investigated. The instrumentation and control cables within the power conduits will not be evaluated. The l&C cables will not add significant heat into the conduit. Furthermore, the I&C cables will help to dissipate heat from the power cables because the thermal conductivity of the l&C cable is higher than that of air. All power conduit applications are listed in Attachment 2. This calculation will not evaluate non-continuous loads which are seldom energized (such as MOVs).

In IPCEA P-46-426, there is a derating for cables which do not maintain spacing on page V. This derating appears to only apphcable to Ladder Supports, Metal Troughs, and Metal Trays. The NEC 1990 uses this same table for dorating conduit. Also Bechtel used this table for derating condults. To be conservative, this table will be used for conduits in this i

calculation. IPCEA P46-426 does not specifically address 1 and 2 conductor cables in conduits. In this calculation when 1 and 2 conductor cables are evaluated, NEC 1990 will be used.

For may applications, the load data from E-11NG20. E-11NG21, E-11PG20, and E-11PG21 was used to determine FLA.

The load data for these documents were acquired from vendor data sheets. These values will be considered as acceptable for this calculation.

An ambient temperature of 50 degrees Celsius'is used. This is the maximum value of ambient temperature for the cables as specified in purchase specifications for the power cables.

The motor space heaters are normally on when the motor is off. To be conservative, it is assumed that these motors are off continuously; therefore, the ampacity dorating should be applied to these unless further analyzed to determine that the circuits are not normally energized.

Vil CALCULATON:

The following calculations are derived from IPCEA P46 426 and the National Electrical Code (NEC) 1990. These standards are used to determine the empacities of cables in conduits.

The results of the calculation formula and methodology from the calculation are used to determine the results. The following equation process was used for each applicabon. The equations are not shown for each application; instead, the result of the equation is shown.

IPCEA P 46-426 Ampacity Method.

eThe ampacity of the c;..i clor is determined by using the applicable table for the cable configuration.

The ampacity of the conductor is then corrected for the ambient temperature and insulation rating temperature of the application using the following formula.

I Tm = - h I = Imm* \\ T ewa - T-.m eThe cable is then dorated for multiple conducton from table on page V.

I = Iww *(Derating Factorin Table)

Then the Ampacity Margin is determined by the following equation.

~

AM = 100%*(1 FLA r bi.)

Iwm t

NEC 1990 Ampacity Method:

l

.The ampacity of the conductor is determined by using the Table 310-16 for the cable configuration.

.The ampacity of the conductor is then corrected for the ambient temperature of the application by multiplying the ampacity above by 0 82 for 9 50 degree C ambient temperature. The factor is derived from Table 310-16.

The cable is then dorated for multiple conductors using the table which in on page 70166. The factor from this l

table is multiplied to the ambient corrected ampacity.

Then the Ampacity Margin is determined by the following equation.

l AM = 100%*(1 FLA.r.6i.)

in addition WCGS has performed Calet'rdion XX-E-008 which specifies ampacity deratings for various conduit sizes in which Thermo-Lag is installed. XX-E-0D8 uses a conservative approach with heat transfer theory to arrive at the ampacity doratings. The results are shown on page 13 of XX-E-008. The results range from 14% for 6" Rigid conduit to 49% to 1/2" EMT conduit.

The 3 hour3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months test results shown above of 9.4% and 9.7% are significantly lower than the ampacity margins listed. The lowest ampacity margin was 40.04% for 3 hour3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months rating applications.

and 11% are significantly lower than the ampacity margins listed. The lowest ampacity margin was 33.04% for 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months rating applications. Therefore, WCGS is not considered to be "at risic for improper ampacity derating for Thermo-Lag 330-1 fire wrap as compared to test results from other organizations.

s To compare the c' lculated ampacity margins with calculation XX-E-008 results, the worst case conduit ampacity margin a

for each conduit is compared to the empacity doratin9 enved from calculation XX-E-006. Calculation XX-E-008 d

The flex conduit was not analyzed in calculation XX-E-006, but it is assumed that the flex conduit thermal heat transfer characteristics are very similar to the condults of the same size. The 2" condults analyzed in the calculation have deratings of 31%,30%, and 30% for 2" EMT,2"IMC, and 2" Rigid conduits, respectively. The 2" flex conduit contains a cable with an empacity margin of 87.58%. By using engineering judgement, the flex conduit is acceptable in comparison to calculation XX-E-008 results.

All of the conduits which were evaluated for ampacity margin meet the requirements for ampacity derating of calculation XX-E-008. Furthermore, the ampacity margins were very conservative compared to the acquired test results from various organizations. Therefore, WCGS does not have any concern with the conduit configuration of the plant for ampacity dorating associated with Thermo Lag 330-1 fire wrapping (using presently available information).

for further discussion of uncertainties potentially impacnag corrective actions.

With regard to NRC Item IILB.3.a., generic test and acceptance criteria for cable raceway L

fire baniers are under development by NRC (draA preposed supplomaat to Generic Letter 86-10), and have been subject to considerable public review, technical scrutiny, CROR and ACRS review, andNRC management involvwment. This criteria, when Saal, would be required for estabushing ramags for cable raceway fire barriers used for protection of safe shutdown ihnetions in accordance with Appendit R. As notad in our I)ecember 17, j

1993, letter, we recamnwnd caution reistrve to licensee's conducting independent five testag for esble raceway five baniers until test and==g--..cc criteria isenes are resolved.

Because of the advantages afforded through the generic review and approval process, we recommend that you propose specific test and acceptance criscria to NRC staff only in unique situations where the generic criteria could not be applied (e.g. s##aas other M that test and than cable raccway Arc barriers). In these situations, it is -W acceptance criteria would be devsloped and discussed with NRC as plant unique or shared testprograms art designed.

ICEA P-54-440 is not referenced in the UL report but due to the uniform loading (one cable size and load), the concept still applies.

ICEA P-54-440 does not give ampacities for cables at depthy greater than 3 inches; however, using Figure 4 from Stolpe's paper one can determine quite accurately the Q value for the 3-5/8" depth tested The percent fill values given in Figure 4 are for 3" trays and 80% approximately represents the maximum cross-sectional area of by UL.

Simply comparing the 90 degree C curve, the 3-5/8" (3.625") depth for percent fill in a 3" deep tray would (3.625" / (3" x 4/3.1416) = 95%).

Then extending the give 95%

By ratio of Figure 4 90 degree C line to 95% vould give a Q of 1.4.

The following table shows a comparison of the baseline ampacity reported by UL and the maximum loading allowed by ICEA (corrected for depth and diameter - 28 amps x.89 x 1.06 = 26.4 amps):
