CONT'D ON SHEET:

This calculation determines the minimum battery size required for the 125 Vdc system based on the Loss Of Offsite Power (LOOP) I Loss Of Coolant Accident (LOCA) and Station Blackout (SBO) duty cycles determined in calculation ES-4.003(Q), and the

. minimum battery charger requirements based on those duty cycles.

This calculation also determines the battery voltage profile for use in the system voltage drop calculation (ES-4.003(Q)). This calculation addresses the 125 Vdc battery systems at the Salem Generating Station, Unit 1 (1A, 1 Band 1 C) and Unit 2 (2A, 28 and 2C) .

.. 3.0 DESIGN BASIS

The batteries will be sized using the guidelines provided in IEEE Std. 485-1983. The duty cycle that will be used for sizing the battery is established in Calculation ES-4.003(Q), (Ref. 6.3). IEEE Std. 485-1983 recommends that batteries be replaced at 80% of their capacity (Ref. 6.1 ). The battery, therefore, must be sized to have adequate capacity when it reaches 80% of its original capacity. This is an aging factor of 1.25 (i.e., 1/0.80 = 1.25). A temperature correction factor of 1.08 (Ref. 6.1) corresponding to a minimum battery room temperature of 65°F (Assumption 5.4) will be used as per the recommendations of IEEE 485-1983. The Design Margin for all batteries is per Assumption 5.1.

~~ · !- .;rhe battery chargers will be sized using the guidelines provided in IEEE Std. 946- // ~ ~S 7~ 1992. The chargers will have the ability to recharge the battery following a design \l ~s duty cycle discharge and carry the normal operating load. The recharge time used

after a discharge is 30 hours (Assumption 5.3). There are two battery chargers per battery, however, only one is normally connected at a time (Ref. 6.6). t)f

4.2 Not Used.

4.3 The C&D, LCR-33 and LC-33 batteries have sixteen positive plates per cell and have 60 cells (Ref. 6.4 and Ref. 6.6).

4.4 The minimum battery electrolyte temperature of 65°F corresponds to a correction factor of 1.08 (Ref. 6.1 ).

4.5 IEEE Std. 485-1983 recommends that batteries be replaced at 80% of their rated capacity (Ref. 6.1 ). The battery, therefore, must be sized to have adequate capacity when it reaches 80% of its original rated capacity. This is an aging factor of 1.25 (i.e., 1/0.80 = 1.25). The Design Margin for all batteries is per Assumption 5. 1 .

4.6 Batteries 1A, 1 B, 1 C, 2A and 28 are type LCR-33 manufactured by C&D Charter Power Systems. The characteristics of the cells are based on the C&D fan curve - Drawing D-841, Revision No. 1, dated April 2, 1987 (Ref. 6.4). Battery 2C is an LC-33, also manufactured by C&D. The characteristics of the LC-33 cells are similar to those of the LCR-33 cells (based on Ref. 6. 7) and, therefore, the fan curve for the LCR-33 cells (Drawing D-841) can be used.

4. 7 The duty cycle for the batteries is obtained from calculation ES-4.003(0), (Ref. 6.3). These values are summarized below:

The design margin will be assumed to be S% for Batteries 1 A , 2A, 1 B, 2B and 2C, however, no design margin was assum~ fQf ~.9~!ery 1 C. These design margins are acceptable because the battery~willbeWaluated for capacity before any new load is added. Thus, a battery can not be overloaded inadvertently due to new load additions.

5.2 For the purpose of the charger sizing calculation, the normal system load is assumed to be the load under normal plant operation. During the recharge of the battery after a discharge, the DC system normal load is assumed to be constant.

5.3 The optimum battery recharge time is a compromise between protecting against a too rapid recharge and minimizing DC System down time. For the purpose of this calculation, a recharge time of 30 hours will be selected arbitrarily.

5.4 The minimum battery electrolyte temperature is assumed to be 65°F. This is conservative since the Battery Rooms draw supply air from the Control Area Relay Rooms, which maintain a temperature of 76°F (Ref. 6.5). Analysis contained in Change Nos. 1 EC-3189, Package No. 1 and 2EC-3163, Package No. 1 (References 6.8 and 6.9) discuss changes made to ensure that the minimum Battery Room temperature remains above 65°F during the postulated events (including SBO).

CALCULATION

METHODOLOGY

7.1.1 Voltage Profile Calculation

The voltage profile at battery end of life is determined by using the manufacturer's fan curve (Ref. 6.4). The cell voltage is determined by the intersection of the cumulative total ampere-hours per positive plate "removed" from the cell during each discharge period and the discharge rate in amperes per positive plate for the specific period. The voltage corresponding to the intersection of the two points is the expected cell voltage. Interpolation between the adjacent "final volts" lines may be required. The cell voltage (V/cell) is then multiplied by the number of cells (i.e., 60) connected in series to obtain the battery terminal voltage. See Section 7.2.1.

7.1.2 Battery Sizing

Salem Station has three safety-related 125 Vdc batteries per unit. They will be sized using the guidelines provided in IEEE 485-1983, using the battery duty cycles developed in Calculation ES-4.003(0).

The load currents and duration for each period of the duty cycle taken from Calculation ES-4.003(0) have been rounded up where necessary. The aging and temperature correction factors are per the design input (Section 4.0) . The batteries are sized two times, once for LOOP/LOCA, and once for the SBO condition. See Attachment 1 for the battery sizing sheets. It is not necessary to consider the "normal load" scenario because, under that scenario, the battery is being maintained at the float voltage and is fully charged. The charger is only

The IEEE 485-1983 cell sizing worksheet is completed as follows:

Using the data for Battery 1A during the LOOP/LOCA loading scenario.

Column 2: The load amperes are obtained from Section 4.7.

Column 3: The change in load amperes between the periods. For the first period this value will be identical to the duty cycle load during the first minute.

Column 4: '

Duration of the period, in minutes. The duration of the first period is 1 minute.

Column 5: Time to end of section, in minutes. This value will be 1 for the first minute

Column 6: The "T Min. Rate" (Rr ) capacity can be obtained from the C&D discharge curves (Ref. 6.4). This is obtained from the intersection of the minute rating curves with the cell voltage curve of the battery at its minimum required voltage 108V (i.e., 1.80V/cell). For the one minute rate this value is the intersection between the 1' line and the minimum cell voltage curve of 1.80. This value is 109 amps/positive plate. This value must be multiplied by the "cell sizing correction factors" table in the upper right hand corner of the graph. For the one minute rate, for the LCR-33 battery, the correction factor is 1.00. Therefore, the actual Rr value is 109 Amps/pas. plate.

ES-4 . 004 (Q) REFERENCE:



..

Column 'l: Required section size. Divide Column 3 by Column 6. This is the amount of positive plates the battery must have to support the duty cycle during the particular period.

Continuing this procedure for all of the duty cycle sections as outlined in IEEE 485-1983. The Column 7 value for the section with the highest required number of positive plates is then multiplied by the temperature correction factor, the design margin and the aging factor. The solution is the minimum required positive plates that the battery requires to support the duty cycle. If this value is less than the number of positive plates available, the battery can support the duty cycle .

7 .1.3 Battery Charger Sizing

= Time in hours to recharge the battery to approximately 95% of capacity

The 8 hour rating of the C&D LCR-33 battery to 1. 75 volts per cell is 2320 A-hr (Ref. 6.6). However, based on the LOOP/LOCA duty cycle (which lasts 2 hours) or the SBO duty cycle (which lasts 4 hours), the battery will not be completely discharged. Per IEEE 946-1992, either the 8 hr ampere-hour rating of the battery or the actual amperehrs discharged from the battery may be used. The ampere hours discharged from the battery during the duty cycle can be calculated using the duty cycle of the battery (Section 4. 7) as follows: ,. !~ • _;;:,... ~«:pru-0·

Using the IEEE Std. 946-1992 equation, the required charger ratings are as follows: (Note: the "continuous load" used for sizing the charger is considered the continuous load during normal plant operation)

LOOP/LOCA

Battery 2A = 87.81A(continuous load Battery 2A)+ 1.1 *(545.92A-hrs /30hrs) = 107.83A

Battery 2B = 117.06A(continuous load Battery 2B)+ 1.1 *(617.02A-hrs/30hrs) = 139.68A

Battery 2C = 79.57 A( continuous load Battery 2C)+1.1 *(735.34A-hrs/30hrs) = 106.53A

8.0 CONCLUSIONS

Battery Sizing The Salem Unit 1 125 Vdc Batteries 1 A, 1 B and 1 C and the Unit 2 125 Vdc batteries 2A, 2B and 2C have adequate capacity to supply the design duty cycle of the 125 Vdc system for both the LOOP/LOCA and SBO loading scenarios. However, battery sizing and voltage drop considerations must be evaluated before any new loads are to be added to the 125 Vdc system.

Battery Charger Sizing The Salem Unit 1 and Unit 2, 125 Vdc battery chargers are Exide, Type USF. They have a continuous output current rating of 250A with current limit capabilities (Ref. 6.6). Two battery chargers are provided for each battery. While one battery charger is in use the other is in standby mode. The results indicate that the required current output of the charger (to support recharging the batteries to 95% capacity in 30 hrs following the postulated discharge duty cycle, while powering the required de loads for steady state operation) may. be set to the most restrictive value (i.e., largest) listed on page 17 of this calculation for Batteries 1A, 18, 1 C, 2A, 28 and 2C .

1. This section was revised to say that IEEE-485 msgmmends that the batteries be replaced. at 800./o of their capacity.

2. This statement has been revised to address the electrolyte tcmpcl3turc rather than th~ ambient tcmperatnrc.

3. This discussion has been revised to rcmovcthc phrase "significant transients". The discussion now says that the load on the charger is assumed constant. One must keep in mind that IEEE-946 does not define "normal load" with respect to charger sizing, therefore, there is some :fleXJl>ility in the term.

4. This assumption has been revised to reflect that the value was arbitrarily selected.

S. As5UIDption S.1 justifies the use of the assmned design margins. The additional load for future growth is not considered design margin. in the traditional sense. This additional load was considered at PSE&G' Iii request to s.ccoun1 for a specific modification.

6. A UFSAR revision was issued during the time between preparation of the calculation and its issuance. The original calculation was marked up to reflect the current revision. The "hange does not impact the design input.

7. The cakulation has been prepared to support the 125Vdc System in its present form. There is currcotly a design Change in progiess to replm: the batter:y chargers. Future growth margin c11n be consideJed as part of the modification process. The future growth value considered for batt.ety sizing was inlendcd for a spcci.fi.c modilication that added load to the vital inverters. The inverters are not included as part of the normal continuous load.
