Calculation 2003-0046 Revision 4 1.0 Purpose The purpose of this calculation is to determine minimum required size and the acceptable range for the current limit set point of the safety related battery chargers. I The battery charger current limit set points for battery chargers D-09, D-107, D-108 and D-l 09 are being changed because of the condition described in CAP033447 (Ref. 5.17). There is a potential for the main supply breaker for battery charger D-09, D-107, D-108 and D-l 09 to trip upon manual restoration after a loss of offsite power with safety injection signal, loss of AC voltage, or station blackout event.
Therefore, the acceptable range for the current limit set point is being determined for battery chargers D- I 07, D-08, D-09, D-107, D-108 and D-109 in this calculation.
The purpose of this revision (Revision 4) is to modify the charger sizing portion of this calculation for consistency with LAR 239 (Ref. 5.29) for Technical Specification 3.8.4.6. This includes a change in the maximum amp-hours assumed removed from the battery prior to recharge as well as revising the maximum continuous load on the battery and charger while recharging. This change reflects the chargers' ability to recharge the battery within the specified time while carrying the maximum continuous DC system load, irrespective of the status of the plant during which these demands occur.
Other aspects of this calculation, other than editorial changes, were not addressed as part of this revision.
2.0 Scope The scope of this calculation is limited to the following battery chargers:
OD-07 OD-08 OD-09 OD-107 OD-108 OD-109 PrF-1 608 Revision 7 08/05/04 Page 5 of 14 Referencc: NP 7.2.4 lI
Calculation 2003-0046 Revision 4 3.0 Methodology The steps performed in determining the required battery charger size, minimum current limit set point and the maximum current limit set point are as follows:
- 1. The minimum battery charger size (current limit set point) required is established by the following equation:
A, = AhxC + A, (Ref. 5.3 and 5.4)
Ar = required minimum charger rating in amperes Ah = total ampere hours discharged from battery during its specified duty cycle C = constant to allow for ampere hour efficiency = 1.10 A, = maximum continuous DC system load while charging (in amperes) tj = required maximum time for recharging
- 2. The maximum battery charger current limit (DC Amps) set point is established by the following equations:
VAIN =( x V..- x I,,
Wof = VAIN x PFx EFF
'DC W VAIN = volt-amperes (Apparent Power into Chargers)
VAC = AC supply voltage in volts IAc = Maximum AC supply current Wour = Watts (Power into DC system from Chargers)
PF = Charger power factor EFF = Charger efficiency VDc = Charger DC output voltage IDC = Charger DC output current
- 3. The battery charger current limit set point is compared to the minimum allowable battery charger size (minimum current limit set point) and maximum allowable set point. A new current limit set point is determined for all battery chargers that are outside the minimum and maximum range.
4.0 Acceptance Criteria 4.1 Battery Chargers must be sized (minimum current limit set point) to recharge any of their respective partially depleted batteries within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> while carrying maximum continuous DC system loads, irrespective of the status of the plant during which these demands occur (Ref. 5.1, 5.2, 5.26, 5.27, 5.28, 5.29, and 5.34). The charger size will be determined to be acceptable if the calculated size (ampere rating) is less than or equal to the installed charger ampere rating.
4.2 The battery charger current limit set points must ensure continuous operation of the chargers at their current limit setting without tripping the over-current protect device (thermal overload) during current limit. (Ref. 5.1 and 5.2)

Calculation 2003-0046 Revision 4 6.0 Assumptions Unvalidated Assumptions - None Validated Assumptions:
6.1 It is assumed that for battery chargers D-07, D-08 and D-09 that the power factor is 0.72.
Basis: This assumption is technically justified in that the power factor using the nameplate information and vendor technical manual (Ref. 5.5) is approximately 0.74 at full load current.
Therefore it is conservative to assume a power factor of 0.72 for battery chargers D-07, D-08 and D-09 for the conditions being evaluated in this calculation.
6.2 It is assumed that the maximum Amp-hours (Ah) discharged from the battery is 925 All.
Basis: The maximum coping period at Point Beach for the station batteries is one hour and then normal AC power supply is restored per the current license basis (Ref. 5.1). The two cell types used for the affected batteries are Exide GN-23 (DO5, D06 and D305) and C&D LCR-2 1 (Dl 05 and D106). Based on a one-hour discharge to a minimum average cell voltage of 1.75 vdc, a maximum of 925 Ah are removed (925 amps for one hour) per Attachment A. Use of 925 Ah is a conservative value to use for all of the chargers.
6.3 It is assumed that the maximum continuous DC system load during charging is 240 AC.:.
Basis: This assumption is technically justificd because the normal DC output current from battery chargers D-07, D-08, D-09, D-107, D-108, and D-109 from plant trending data over the past 4 years ranges from approximately 120 amps to 170 amps (Ref. 5.18). Previously this was based on an
"'average" current value of the most limiting system. A re-review of the plant trending data revealed that excursions beyond 170 amps were brief and do not reflect normal plant operation. All charger peak loads during the past 4 years were reviewed by the PBNP DC system engineer and correlation to testing or maintenance activities on the systems were found. This correlation is documented in Attachment B. Based on this, 170 amps will be used as a conservative base loading condition during normal operation for each charger.
It is expected that the DC continuous loads during any operating condition would be similar since the major DC motor loads (such as the feedwater pump bearing oil pumps, main turbine bearing oil pumps and main generator seal oil pumps) have been placed on the non-vital batteries. Major pealk loads, such as emergency diesel field flashing and breaker actuations are momentary in nature. The instrumentation loads do not significantly increase due to a Design Basis Accident or other operating scenarios since the instrumentation is normally energized and remains energized. A review of the system one-lines (Ref. 5.30, 5.31, 5.32, and 5.33) was performed and it was determined that the only significant continuous load additions that would occur, beyond those for normal plant operation, are additional annunciator loading and EDG control loads. Some control loads would itcrease during accident conditions, such as safeguards actuation relays (energize to actuate), while other loads are expected to decrease, such as reactor protection relays (deenergize to actuate) and containment isolation valves (deenergize to close). For conservatism, an additional load of 30 ADC per charger is assumed to account for additional annunciators that may be lit during non-normal operating PBF-160R Revision 7 08/05104 Page9ofl4
Reference:
NP 7.2.4 l
Calculation 2003-0046 Revision 4 conditions. This equates to more than 225 additional annunciators at a conservative value of 16 watts per window (Ref. 5.35). An additional 5 AwC load per charger is assumed for EDG control loads. This equates to more than 40 additional relays at a conservative value of 15 watts per relay (Ref. 5.36). To support future load growth, 20 ADC is added (approximately 11.5% of the maximum measured continuous value). Finally, an additional 15 ADc conservative margin of load per charger is assumed for miscellaneous control loads. Therefore, the assumed value of 240 AnC (170 AI)c maximum measured value for normal operating conditions plus an additional 70 ADO' for annunciators, EDG control loads and additional margin to allow for off-nonnal plant conditions and future load growth) is considered to be conservative.
6.4 It is assumed that the minimum AC supply voltage for the battery chargers while they are in current limit is 450 VAC.
Basis: This assumption is technically justified in that the worst-case minimum AC supply voltage at the battery charger input terminals is 455 VAC (Ref. 5.14) while loaded on the emergency diesel generators. The battery charger will be in current limit upon restoration after a loss of AC voltage to the contactors (Loss of offsite power with Safety injection signal, loss of AC voltage or station blackout). When the battery chargers are restored, the battery chargers will only be supplied on the emergency diesel generators, gas turbine, or offsite power (only if restored to normal). The voltage at the terminals of the battery charger when supplied by the gas turbine or offsite power will be between 480 to 500 VAc. A review of plant trending (Ref. 5.18) demonstrates the voltage on both unit B03 and B04 normally average between 480 to 500 VAC. The gas turbine will provide similar voltage ranges because the output voltage of the generator per 0 110 (Ref. 5.15) is maintained between 13.8 and 14.2 kV on the 13.8 kV bus. These voltages are equal to or greater than the voltages seen during normal operation. Therefore, it is conservative to assume a minimum AC supply voltage of 450 VAc for the conditions evaluated in this calculation.
6.5 It is assumed that the maximum charger output voltage is 136 VDx- while recharging the battery and supplying the DC load.
Basis: This assumption is technically justified in that the calibration procedure for battery chargers D-07, D-08 and D-09 is set between 132.5 to 133 V1 ,c (Ref. 5.16). The calibration procedure for battery chargers D-107, D-108 and D-109 is set between 133.5 and 134.5 VDC (Ref. 5.22). The normal operating range of the battery chargers is 130 and 136 VDC (Ref. 5.16 and 5.22). Therefore, it is conservative to assume the maximum charger DC output voltage of 136 V1 C for the conditions evaluated in this calculation.

Calculation 2003-0046 Revision 4 9.0 Results and Conclusion Battery chargers D-07, D-08 and D-09 are adequately sized to meet the minimum charger size required of 283 ADC (400 ADC rated). The recommended range for the current limit set point for battery chargers D-07, D-08 and D-09 is 283 to 375 Ai)c. The recommended set point for battery chargers D-07, D-08 and D-09 is 350 ADc. Given a -10 to +5 AKx setting tolerance, this set point allows approximately 5%
margin for the total tolerance (set point drift and M&TE tolerance).
Battery chargers D-107, D-108 and D-109 are adequately sized to meet the minimum charger size required of 283 AtDc (500 ADC rated). The recommended range for the current limit set point for battery chargers D-107, D-108 and D-109 is 283 to 497 ADC. The recommended set point for battery chargers D-107, D-1 08 and D-109 is 450 ADC. Given a -10 to +10 Aixc setting tolerance, this set point provides more than a 5% margin for the total tolerance (set point drift and M&TE tolerance).
The calculation determined the minimum charger size required and the acceptable current limit set point range for battery chargers D-07, D-08, D-09, D-107, D-108, and D-l 09. The acceptance criteria will be achieved for all battery chargers when the current limit set points are within the acceptable range identified above.
