Purpose 1This calculation serves as an addendum to the Low Voltage (208/120. volt) Electrical Distribution System Study,' Revision 1,

.. July 27, 1984," conducted'by Duke Power. Company (Reference 6.1).

The purpose of:this addendum is to perform a more detailed

~

analysis of ;the three (3) 120 volt safety-related circuits which were identified as having.a potential undervoltage problem under a postulated loss of coolant accident (LOCA).

2.0 Summary of Results

' The Low Voltage Electrical Distribution Study (Reference 6.~1) #

identified three (3) safety-related circuits which did not meet the voltage regulation performance criteria under a

(

. postulated degraded voltage condition following a LOCA ("LOCA--

Run").

The load data used in the calculation (References 6.2 and 6.3) included some. generic conservative. assumptions to provide the." worst case" results for all circuits analyzed.

C Each' circuit was represented as one single lumped load with

. impedance of the longest feeder length in the circuit. A detailed analysis of each of the three (3) circuits (see Appendix A) revealed that all voltage criteria are met when the above. referenced conservatisms are removed. A summary of the results is chown in Table 1, Page 4.

4 3.0 Method of _ Calculation EA detailed voltage calculation was performed for each of the three (3) circuits. In each circuit, a voltage calculation was done for the component that has the~ lowest terminal volt-age (i.e., the largest load at the far and of the circuit).

4.0 Discussion of Results The three- (3) circuits identified as having potential under-r-

l voltage problems during a LOCA-Run condition aret

4.1 Circuit 12, Panel 2D 1 -

This circuit from Reference 6.1 was assumed as a single lumped load with feeder size, length, load, and terminal voltage as follows:

j Feeder Size:

1. 12

~&

7 Length:

1961 ft.

F Load:

240 VA @ 0.5 PF (LAG)

Load Terminal Voltage:

0.8929 p.u.

This circuit actually consists of several components which are

+

described in Figure 3 on Page A4.

The detailed voltage calculation for this circuit based on the actual circuit

=

arrangement described on Pages A4, A5, and A6 revealed that

_f the component with the lowest voltage is 20/c with a terminal

.t

~

voltage of 0.9376 p.u.

Since this voltage is above the minimum m

required voltage of 0.90 p.u., no modifications are required.

4.2 circuit 18, Panel 1AB-TB This circuit from Reference 6.1 was assumed as a single lumped i

load with feeder size, length, load, and terminal voltage as i

follows:

Load:

882 VA @ 0.5 PF (LAG)

Load Terminal Voltage:

0.8398 p.u.

This circuit actually consists of several loads which are described in Figure 5 on ? age A7.

The detailed voltage calculation for this circuit based on the actual circuit 9

arrangement described in Pages A7, A8, and A9 revealed that the component with the lowest voltage is Contactor #4 with a terminal voltage of 0.9450 p.u.

Since this voltage is above

~ _ -

~ he minimum required voltage of 0.90 p.u., no modifications t

are required.

4.3 Circuit 16 of Panel 2AB-TB This circuit from Reference 6.1 was assumed as a single lumped load with feeder size, length, load, and terminal voltage as follows:

Feeder size:

1. 12 Length:

648 ft.

l Circuit 16 of Panel 2AB-TB actually consista of several loads which are described in Figure 7 on Page A10.

The detailed calculation based on the actual arrangement as desetibed on Pages A10, All, and A12 revealed that the component with the lowest voltage is Contactor #3 with a terminal voltage of 0.9460 p.u.

Since this voltage is above the minimum required voltage of 0.90 p.u., no modifications are required.

Conclusions:==

The detailed analysis of each of the three (3) circuits identi-fled as having a potential undervoltage problem showed that the 208/120 VAC safety system maintains adequate voltage during LOCA-Run and no modifications are required.
