CA-02-192, "MNGP 125 Volt Div. II Battery Calculation" with only Attachment K (11 total pages) fl Xcel Energy.. calculation Page No.: 02-192 Rev 003A 1.0 Purpose/Objective This minor revision is prepared to revise the DCSDM scenario step time entry format to address the issue documented under CAP AR 01474466. Specifically, colons are replaced with periods between the digits for seconds and tenths of a second. The pending changes associated with EC 25695 are also incorporated in the DCSDM database under this minor revision. 2.0 Methodology The methodology of Revision 003 remains unaffected. 3.0 Acceptance Criteria Acceptance criteria are not changed by this minor revision. 4.0 Assumptions This minor revision adds no assumptions. 5.0 References The following references are added under this minor revision. 5.9 DC Load Study Reports 5.9.1 DC Load Study Report EC 25695-Evaluate Replacement for Obsolete Relays ESRX1/2, ZSR1/2, MSR1/2, VSR1/2 6.0 Input Data Revision 003 inputs are unaffected by this minor revision. 7.0 Calculation The database file which was used to perform this analysis is: 02-192_Rev003A.db, 03/22/201610:46, 19,130,368 bytes 8.0 Results and Conclusions The conclusions of revision 003 remain unchanged in that the battery is sufficiently sized to support the required duty cycle. 8.1. Device Voltage All devices analyzed meet the acceptance criteria defined in base revision 003 Section 3.2 with the following justifications: Items with negative voltage margins are identified in Attachment C, along with justifications for their acceptability. The most limiting loads for each of the batteries are described below. These devices and others that were close to limiting were reviewed and additional analysis performed (voltage divider analysis) to more accurately calculate actual terminal voltage. The results of these additional analyses are provided below. Some of the low margin loads are part of nonsafety related circuits and not required to operate during the various scenarios (as described in Attachment Q) or CA-02-192, "MNGP 125 Volt Div. II Battery Calculation" fl.* Xcel Energy .. Calculation Page Calculation No.: 02-192 Rev 003A Page 2 of 4 are annunciator circuits that have short term voltage drops due to other occurrences (i.e. spring charge motor inrush or EDG field flash. Thus these loads were not considered in determining the minimum required battery voltage. The low margin loads were determined from a review of the Path Voltage Drop summary (Attachment B). Loads on safety related circuits with less than 2.0 volts of margin were reviewed and a summary is shown below. 8.2. Battery Sizing 8.2.1. Minimum Battery Terminal Voltage As outlined in base revision 003 Section 2.2, Attachment B was reviewed to determine the minimum required terminal voltage for the battery. Additionally, the resolutions for several of the devices in Attachment C are also included in this review since the validity of those resolutions is dependent upon maintaining adequate voltage at the nodes supplying the devices. Attachment F was also reviewed to determine the times in the scenario where the minimum device voltages are present. The details of this review are as follows: There are several devices supplied from Panels C84A, C84B, and the C04 annunciators (Nodes 28, 31, and 33, respectively) with voltage margins of 1.25 volts or less. These are all are annunciator circuits that have voltage margin greater than 3 volts (as shown in Attachment F) for all time periods except for the last minute of the scenario (when the EDG is manually started for the SBO scenario and there are 4 kV breaker spring charge motors at inrush). The relay contacts in these circuits are used for annunciator functions only with no impact to plant equipment. Further review of Attachment B and the resolutions for the circuit breaker closing coils in Attachment C indicate that there are four time periods that require examination in determining the minimum required battery terminal voltage. These time periods are the first minute, the 120th minute, and the last 2 minutes of the scenario. The devices with the lowest margin in the first minute of the event are located at 13 kV Swgr #12 (Node 21) and 4 kV Switchgear No. 16 (Node 23). Since the 13 kV Swgr is not Class 1 E (not safety related), these loads are will not be considered. On 4 kV Switchgear No. 16 (Node 23), the devices are the close coils for Breaker 152-604 and 152-605. These circuits are discussed in attachment C and are shown to require 105.57 Vdc and 105.64 Vdc, respectively, at node 23. The most limiting of these two is the close coil for 152-605 with a margin of 1.84 volts. From Attachment F, the battery terminal voltage during the first minute is 110.90 Vdc. The required battery terminal voltage for the first minute is then (110.90 -1.84) 109.06 Vdc. This is equivalent to 1.881 Volts per Cell for the 58 cell battery. There are several circuit breaker closures modeled in the last minute of the second hour of the scenario. Two of the close coils for these breakers are analyzed in Attachment C. From examination of the disposition in Attachment C, the close coil for circuit breaker 152-605 (Device 152-605-CC) is limiting and has an operating margin of 0.45 Vdc when operated in the last minute of the second hour. From Attachment F, the battery voltage during the final minute of the second hour is 109.31 Vdc. The required battery terminal voltage at the end of two hours is then (109.31-0.45) 108.86 Vdc. This is equivalent to 1.877 Volts per Cell for ttie 58 cell battery. Since required CA-02-192, "MNGP 125 Volt Div. II Battery Calculation" lJ, Xcel Energy* Calculation Page Calculation No.: 02-192 Rev 003A Page 3 of 4 battery voltage at the end of two hours is less than that required for the first minute and the calculated battery terminal voltage at the end of two hours is greater than the minimum required for the first minute, the minimum required voltage determined for the first minute will be used for the first two hours of the event. From examination of Attachment B and the dispositions in Attachment C, the limiting device for the next to last minute (3:58 to 3:59) of the event is the close coil for circuit breaker 152-610 (Device 152-610-CC). This close coil is analyzed in Attachment C. From examination of the disposition in Attachment C, the close coil for circuit breaker 152-610 (Device 152-610-CC) has an operating margin of 2.74 Vdc when operated in the next to last minute of the scenario. From Attachment F, the battery terminal voltage during the next to last minute of the event is 109.71 Vdc. The required battery terminal voltage at the next to last minute of the scenario is then (109.71 -2.7 4) 106.97 Vdc. This is equivalent to 1.845 Volts per Cell for the 58 cell battery. This voltage is lower than the minimum required for the first two hours of the event and allows for a separate battery sizing analysis. From examination of Attachment B and the dispositions in Attachment C, the limiting devices for the last minute of the event are part of the EOG 12 starting control circuit (Node 20). The two most limiting loads are the Booster Pump Motor (0211-11-BPM) with a margin of 0.40 Vdc at time step 58 and the main start solenoid valve (MVST1/C-92) with a margin of 1.34 Vdc at time step 56. The EOG start sequence begins at time step 56 and the voltage at the BPM dips momentarily due to the EOG field flash energizing during the manual start of the EOG at the end of the scenario. This motor is already running when this slight voltage dip occurs and will continue running during time step 58 (when the EOG flashes). This leaves the main start solenoid valve as the limiting load. From Attachment F, the battery terminal voltage during the last minute of the event is 106.50 Vdc. The required battery terminal voltage at the end of the scenario is then (106.50 -1.34) 105.16 Vdc. This is equivalent to 1.814 Volts per Cell for the 58 cell battery. This voltage is lower than the minimum required for the first 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and 59 minutes of the event and allows for a separate battery sizing analysis. The minimum required voltages for the composite scenario are: Scenario Min Required Terminal Volts Min Required Cell Volts D2DBA -First 120 Min 109.06 1.881 D2DBA -2:00 -3:59 106.97 1.845 D2DBA -Last Min of Event 105.16 1.814 CA-02-192, "MNGP 125 Volt Div.

Minimum Required Battery Size Calculation Page Calculation No.: 02-192 Rev 003A Page 4 of 4 Battery 02 (C&O KCR-13 Cells) was shown to be adequately sized for the evaluated scenario and corresponding load profile. The acceptability of the battery is based on the results of Attachments H1, H2 and H3. The battery size is determined using the minimum required battery terminal voltages determined in Section 8.2.1. Scenario Required Cell Size Actual Cell Size Spare Capacity 020BA -First 120 Min 5.82 Positive Plates 6 Positive Plates 3.09% 020BA -2:00 -3:59 5.04 Positive Plates 6 Positive Plates 19.05% 020BA -Last Min of Event 5.33 Positive Plates 6 Positive Plates 12.57% 8.2.3. Minimum Number of Cells Based on these results, an analysis of the battery will not be performed to determine the number of cells that can be removed from service while maintaining adequate battery capacity as it is clear that there is not adequate margin to remove a cell and maintain a positive design margin with cells removed and the parameters used in this calculation. 8.3. Margin Load An additional 1.0 Ade constant impedance load is included on panel 021 to allow for future load additions. 8.4. Cable Ampacity Verification The cables in the system are sized adequately with regard to ampacity as described in section 7.7 of major revision 003. 9.0 Plant Impact 9.1. No new Future Actions are identified in this minor revision.
