NRC Administrative Letter 98-10, "Dispositioning of Technical Specifications That Are Insufficient to Assure Plant Safety," dated December 29, 1998 In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC) requests an amendment to Renewed Facility Operating License Nos. DPR -29 and DPR-30 for Quad Cities Nuclear Power Station (QCNPS), Units 1 and 2, respectively. The proposed change revises Technical Specifications (TS) Surveillance Requirements (SR) 3.8.4.2 and SR 3.8.4.5 to add new acceptance criteria for total battery connection resistance.

The proposed change resolves a non-cited violation (NCV) that was documented in the Reference 1 NRC Inspection Report. Specifically, the NRC identified an NCV for the failure to verify that safety-related batteries would remain operable if all the inter-cell and terminal connections were at the maximum resistance value allowed by SR 3.8.4.2 and SR 3.8.4.5 (i.e.,

150 micro-ohms). The proposed change maintains the existing resistance limit for inter-cell and terminal connections, and adds new acceptance criteria for total battery connection resistance to ensure that QCNPS safety-related batteries can perform their specified safety function.

Currently plant operations in TS 3.8.4 are administratively controlled under the provisions of NRC Administrative Letter (AL) 98-10 (i.e., Reference 2) to assure that plant safety is maintained. This license amendment request is submitted in accordance with the guidance in AL 98-10. In accordance with the guidance of AL 98-10, EGC submits the proposed change as a required license amendment request to resolve a non-conservative TS.

3.0 TECHNICAL EVALUATION

The safety-related direct current (DC) electrical power systems include the 125 volt DC (VDC) and 250 VDC systems, which provide a source of DC power for certain vital loads and control power. As required by Section 8.3.2 of the QCNPS Updated Final Safety Analysis Report (UFSAR), the DC electrical power system is designed to have sufficient independence, redundancy, and testability to perform its design function, assuming a single failure.

The 250 VDC system provides motive power to large DC loads such as DC motor-driven pumps and valves. Each QCNPS unit includes a 250 VDC source consisting of a 250 VDC battery and an associated 250 VDC full capacity battery charger. An additional 250 VDC full capacity charger is available for use between the units. Each 250 VDC battery and charger supplies power to both Unit 1 and Unit 2 loads. The minimum required battery terminal voltage for the QCNPS 250 VDC batteries is required, as stated in Section 8.3.2.1 of the QCNPS UFSAR, to be at least 210 VDC.

The 125 VDC electrical power system provides control power to selected safety-related equipment as well as circuit breaker control power for certain 4160 volts alternating current (VAC) and 480 VAC circuit breakers, and power to certain control relays and alarm annunciators. Each QCNPS unit includes a 125 VDC source consisting of a 125 VDC battery and two 125 VDC full capacity chargers (i.e., normal and alternate). Each 125 VDC unit source (i.e., 125 VDC battery and associated charger) supplies power to the associated unit Division 1 125 VDC electrical power distribution subsystem and the opposite unit Division 2 125 VDC electrical power distribution subsystem. The design also includes a safety-related alternate 125 VDC battery (i.e., one for each unit), which can be used when the normal 125 VDC battery is out-of-service for maintenance. The minimum required battery terminal voltage for the QCNPS 125 VDC batteries is required, as stated in Section 8.3.2.2 of the QCNPS UFSAR, to be at least 105 VDC.

Normally, the 250 VDC and 125 VDC battery chargers carry the DC loads, while maintaining their associated battery's terminal voltage. In the event of a loss of normal power to the battery charger, the DC loads are automatically powered from their associated battery. Each battery has adequate storage capacity to carry the required normal loads plus all loads required for safe shutdown on one unit and operations required to limit the consequences of a design basis event on the other unit for a period of four hours.

The safety-related batteries at QCNPS are formed by strings of battery cells. These strings are comprised of a series connection of the positive and negative terminal posts of adjacent cells as shown in Figure 1.

Figure 1: Typical Battery Configuration The inter-cell and terminal connections (i.e., inter-tier and inter-rack connector cables and connections) between the cells contribute to the total battery connector resistance, which reduces the overall battery terminal voltage. During normal operation of the battery, corrosion can occur on the battery posts, which can also increase the inter-cell and terminal connection resistance and further reduce battery terminal voltage. If the battery is not properly maintained, this condition could eventually reduce the affected battery's terminal voltage to a point where the minimum required voltages (i.e., 105 VDC for the 125 VDC battery and 210 VDC for the 250 VDC battery) cannot be met. The total battery connector resistance includes inter-cell and terminal connection resistance.

In Reference 2, the NRC identified a non -cited violation (NCV) for the failure to verify that safety-related batteries would remain operable if all the inter -cell and terminal connections were at the maximum resistance value allowed by SR 3.8.4.2 and SR 3.8.4.5 (i.e., 150 micro-ohms).

In response to the non-conservative TS value, EGC initiated administrative controls in accordance with NRC AL 98-10 (i.e., Reference 1) as a short-term corrective action to ensure the safety-related batteries continue to be capable of performing their safety function in the interim until a license amendment correcting the non-conservative TS is approved.

EGC previously submitted a license amendment request to resolve the non-conservative TS in Reference 3. That license amendment request proposed adding an additional SR acceptance criterion to verify that total battery connector resistance is within pre-established limits that ensure the batteries can perform their specified safety functions. The Reference 3 license amendment request proposed maintaining the total battery connector resistance limits in a licensee controlled document (i.e., the TS Bases), such that future changes would be evaluated in accordance with 10 CFR 50.59, "Changes, tests, and experiments." EGC ultimately withdrew the Reference 3 license amendment request in Reference 4, following numerous interactions with the NRC related to whether maintaining the total battery connector resistance limits in a licensee controlled document met the requirements of 10 CFR 50.36, "Technical specifications."

Based on additional evaluations by EGC, including consideration of Technical Specifications Task Force (TSTF) traveler TSTF-500, "DC Electrical Rewrite - Update to TSTF-360," EGC has determined that it is appropriate to include total battery connector resistance limits within the TS, Page 4

ATTACHMENT 1 Evaluation of Proposed Change given the relationship between battery operability and connector resistance. Therefore, the proposed change requested herein includes the total battery connector resistance limits within SRs 3.8.4.2 and 3.8.4.5. As discussed above, administrative controls have been put in place to address the non-conservative IS, and these controls will remain in place until such time that a license amendment correcting the non-conservative TS is implemented.

SRs 3.8.4.2 and 3.8.4.5 establish the requirement to perform inspections and resistance measurements to detect localized battery connector degradation. Visual inspection to detect corrosion of the battery cells and connections, or measurement of the resistance of each inter-cell and terminal connection, provides an indication of physical damage or abnormal deterioration that could potentially degrade battery performance if left uncorrected. The specific resistance value (i.e., 150 micro-ohms) was not initially established as an absolute limit for battery operability. The value was based on industry experience as a threshold for identifying localized degradation so that issues potentially affecting battery performance are promptly identified and corrected.

The new acceptance criterion to verify that the total battery connector resistance is within pre-established limits ensures that the batteries can perform their specified safety function by maintaining required battery terminal voltage under design-basis load conditions. The total battery connection resistance is a parameter that is more representative of overall battery performance, and ensures that the safety-related batteries remain capable of performing their specified safety function. The surveillance frequencies for SRs 3.8.4.2 and 3.8.4.5 are controlled under the Surveillance Frequency Control Program, and verification of total battery connector resistance (i.e., the new acceptance criterion) will be performed at the same frequency as the existing visual inspection and inter-cell and terminal connection resistance measurements.

As stated above, the 125 VDC and 250 VDC battery terminal voltages must remain above 105 VDC and 210 VDC, respectively, during worst-case accident conditions. While the design basis load calculations include the manufacturer's total connection resistance, an increase in battery cell connection resistance due to corrosion would produce voltage drops along the battery string, which if large enough, could drop the battery terminal voltages below their minimum requirements.

A calculation, which is provided in Attachment 4, was performed to determine the maximum total allowable connector resistance for each of the safety-related batteries. Using the accident load profiles for each battery, the calculation determined maximum allowable resistances for each of the safety-related batteries. Table 1 lists the acceptance criteria for safety-related total battery connector resistance.

4.0 REGULATORY EVALUATION

4.1 Applicable Regulatory Requirements/Criteria 10 CFR 50.36(c)(3), "Surveillance requirements," requires that TSs include SRs, which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

The proposed change to SRs 3.8.4.2 and 3.8.4.5 do not alter the design or function of any DC electrical power system; do not result in any change in the qualifications of any component; and do not result in the reclassification of any component's status in the areas of shared, safety-related, independent, redundant, or physical or electrical separation. Therefore, compliance with the regulatory requirements above will be maintained.

4.2 No Significant Hazards Consideration In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC) requests an amendment to Renewed Facility Operating License Nos. DPR-29 and DPR-30 for Quad Cities Nuclear Power Station (QCNPS), Units 1 and 2, respectively. The proposed change revises Technical Specifications (TS) Surveillance Requirements (SR) 3.8.4.2 and SR 3.8.4.5 to add new acceptance criteria for total battery connection resistance to ensure that QCNPS safety-related batteries can perform their specified safety function.

According to 10 CFR 50.92, "Issuance of amendment," paragraph (c), a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not:

The total battery connection resistance is a parameter that is representative of overall battery performance, and ensures that the safety-related batteries remain capable of performing their specified safety function.

4.0 REGULATORY EVALUATION

4.1 Applicable Regulatory Requirements/Criteria 10 CFR 50.36(c)(3), "Surveillance requirements," requires that TSs include SRs, which are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

The proposed change to SRs 3.8.4.2 and 3.8.4.5 do not alter the design or function of any DC electrical power system; do not result in any change in the qualifications of any component; and do not result in the reclassification of any component's status in the areas of shared, safety-related, independent, redundant, or physical or electrical separation. Therefore, compliance with the regulatory requirements above will be maintained.

4.2 No Significant Hazards Consideration In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC) requests an amendment to Renewed Facility Operating License Nos. DPR-29 and DPR-30 for Quad Cities Nuclear Power Station (QCNPS), Units 1 and 2, respectively. The proposed change revises Technical Specifications (TS) Surveillance Requirements (SR) 3.8.4.2 and SR 3.8.4.5 to add new acceptance criteria for total battery connection resistance to ensure that QCNPS safety-related batteries can perform their specified safety function.

According to 10 CFR 50.92, "Issuance of amendment," paragraph (c), a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not:

ATTACHMENT 1 Evaluation of Proposed Change (1)

Involve a significant increase in the probability or consequences of any accident previously evaluated; or (2)

Create the possibility of a new or different kind of accident from any accident previously evaluated; or (3)

Involve a significant reduction in a margin of safety.

EGC has evaluated the proposed change, using the criteria in 10 CFR 50.92, and has determined that the proposed change does not involve a significant hazards consideration. The following information is provided to support a finding of no significant hazards consideration.

1.

Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The revisions of SR 3.8.4.2 and SR 3.8.4.5 to add a battery connector resistance acceptance criterion will not challenge the ability of the safety-related batteries to perform their safety function. The total battery connection resistance is a parameter that is representative of overall battery performance, and ensures that the safety-related batteries remain capable of performing their specified safety function. Appropriate monitoring and maintenance will continue to be performed on the safety-related batteries. In addition, the safety-related batteries are within the scope of 10 CFR 50.65, "Requirements for monitoring the effectiveness of maintenance at nuclear power plants," which will ensure the control of maintenance activities associated with this equipment.

Current TS requirements will not be altered and will continue to require that the equipment be regularly monitored and tested. Since the proposed change does not alter the manner in which the batteries are operated, there is no significant impact on reactor operation.

The proposed change does not involve a physical change to the batteries, nor does it change the safety function of the batteries. The DC power system/batteries will retain adequate independency, redundancy, capacity, and testability to permit the functioning required of the engineered safety features.

The proposed TS revision involves no significant changes to the operation of any systems or components in normal or accident operating conditions and no changes to existing structures, systems, or components.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The revisions of SR 3.8.4.2 and SR 3.8.4.5 to add a battery connector resistance acceptance criterion will not challenge the ability of the safety*related batteries to perform their safety function. The total battery connection resistance is a parameter that is representative of overall battery performance, and ensures that the safety-related batteries remain capable of performing their specified safety function.

The proposed change does not involve a phYSical change to the batteries, nor does it change the safety function of the batteries. The DC power system/batteries will retain adequate independency, redundancy, capacity, and testability to permit the functioning required of the engineered safety features.

The proposed TS revision involves no significant changes to the operation of any systems or components in normal or accident operating conditions and no changes to existing structures, systems, or components.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

ATTACHMENT 1 Evaluation of Proposed Change 2.

Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed changes revising SR 3.8.4.2 and SR 3.8.4.5 to add an additional acceptance criterion for battery connector resistance is an increase in conservatism, without a change in system testing methods, operation, or control.

Safety-related batteries installed in the plant will be required to meet criteria more restrictive and conservative than current acceptance criteria and standards. The proposed change does not affect the manner in which the batteries are tested and maintained; therefore, there are no new failure mechanisms for the system.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3.

Does the proposed change involve a significant reduction in a margin of safety?

Response: No The margin of safety is established through the design of the plant structures, systems, and components, the parameters within which the plant is operated, and the setpoints for the actuation of equipment relied upon to respond to an event. The proposed change does not modify the safety limits or setpoints at which protective actions are initiated. The new acceptance criterion is more restrictive than the existing acceptance criteria for inter-cell and terminal connection resistance, and the proposed change ensures the availability and operability of safety-related battery operability and availability.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above evaluation, EGC concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92, paragraph (c), and accordingly, a finding of no significant hazards consideration is justified.

4.3 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or the health and safety of the public.

ATTACHMENT 1 Evaluation of Proposed Change

5.0 ENVIRONMENTAL CONSIDERATION

EGC has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, "Standards for Protection Against Radiation." However, the proposed amendment does not involve: (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22, "Criterion for categorical exclusion; identification of licensing and regulatory actions eligible for categorical exclusion or otherwise not requiring environmental review,"

paragraph (c)(9). Therefore, pursuant to 10 CFR 51.22, paragraph (b), no environmental impact statement or environmental assessment needs to be prepared in connection with the proposed amendment.

Page 3of14 Purpose/Objective This calculation is in response to a 2006 NRC Component Design Basis Inspection (CDBI) finding which concluded that the maximum intercell resistance value of 150 micro-ohms specified in surveillance requirements SR 3.8.4.2 and 3.8.4.5 of the Technical Specifications was non-conservative (Ref. 12). Specifically, if all the intercell connection resistances were allowed to reach their 150 micro-ohm limit, the voltage drop produced by the worst case battery loading would cause the battery terminal voltage to drop below its UFSAR requirement of 105 VDC and 210 VDC for the 125 and 250 VDC batteries respectively (UFSAR Section 8.3.2).

This calculation will determine a conservative resistance value for each safety related battery in use at Quad Cities Station. The existing 150 micro-ohm value will remain in the Technical Specifications as a limit for each battery intercell connection. However, new resistance limits for the entire battery string will be calculated and will become an additional acceptance criteria in the Technical Specifications for the Unit 1(2) 125 VDC and 250 VDC Safety Related Batteries.

The individual intercell resistances obtained through field measurements per the Technical Specification Surveillances discussed above are summed to form an as-found battery string resistance for each battery. These string resistances are verified against the acceptance criteria determined per this calculation.

Methodology and Acceptance Criteria Battery strings are formed by a series connection of the positive and negative terminal posts of individual cells. The positive post of one cell is connected to the negative post of the next cell by intercell connector plates which are bolted to each post. This intercell connection, however, produces a small resistance which drops the overall battery terminal voltage. Excessive corrosion on the battery posts can cause the intercell connection resistance to increase which could drop the terminal voltage to a point where the 105 VDC and 210 VDC minimum requirements may not be met. Per Reference 1, the battery cell manufacturer accounts for normal intercell connection resistance in it's battery cell discharge curves. Any resistance beyond this value must be accounted for by the DC system designer. This includes the added resistance from the following sources:

1. Elevated intercell connector resistance due to corrosion 2.

Resistance from the inter-rack jumper cables and connections

3. Resistance from the inter-tier jumper cables and connections 4.

Resistance of the cable lug to post connection at the battery terminals Figure 1 below is a representation of a typical battery configuration showing the various resistive elements. The number of cells is dependant on the battery's total voltage. Figure 2 is a schematic representation of this battery arrangement. Note that in each string (Ref. 14) the inter-tier and inter-rack connections (terminal connections) and cable types are the same. For simplicity, both types of connections will be referred to as inter-rack connections.

Page 5 of 14 Methodology Maintenance personnel check battery intercell resistances with a micro-ohm meter. This is done by placing the micro-ohm meter on the intercell connector which connects the positive post of one cell and the negative post of the next adjacent cell. The resistance value obtained is actually the sum of the normal intercell connector resistance (which is already accounted for in the battery manufacturer's discharge curves) plus any additional resistance due to degradation of the plate-to-post connection (e.g. corrosion). It's this additional resistance that is a concern when maintaining the UFSAR minimum voltage requirement (105 VDC, 210 VDC). If this resistance becomes high enough, the extra loading it produces would remove the remaining capacity in the battery and cause the battery terminal voltage to drop below the minimum requirement.

The ELMS-DC program will be used to determine the total allowable battery string resistance based on the remaining battery capacity of each of the six safety related batteries. The following steps will be used for each battery to determine this maximum allowable resistance:

1. From references 2 and 3, the latest ELMS-DC files will be identified for each battery.

2.

From the applicable ELMS-DC file, the "Minimum Battery Voltage" will be increased slightly until a positive remaining battery capacity (just above 0%) is found. The voltage that produces this result will be designated as VMin. The difference between VMIn and the minimum required voltage, VRequired (e.g. 105 VDC) is the amount of margin that exists to mitigate any increase resistance due to corrosion. This value will be designated as V.

Therefore, VX = VMin - VRequired

3. From reference 1, the battery manufacturer allows for a 0.020 volt drop across each intercell, and inter-rack connection. From references 2 and 3, both the 125 VDC and 250 VDC batteries utilize NCN-21 cells manufactured by GNB. From the data sheet for these batteries (Ref. 27, page B3), the NCN-21 cells have a 1-hour discharge rate of 750 amps when discharged to 1.75 volts/cell. From Ohm's Law, the cell manufacturer's design intercell resistance is, Ric _

VDrop - Manuf 0.020 Volts

= 26.67 µS2 11 - Hour 750 Amps

4. To determine the total resistance accounted for in the vendor discharge curves, the intercell resistance Ric will be multiplied by the number of intercell connectors, inter-rack connections, and the feed cable to lug connections. Since the vendor assumes the same voltage drop for each type of connection, the various connections will be combined into a single sum. The total vendor resistance is, Rvendor = (Ric)(Nceii + Nlnter-Rack + Niug-post) = (RIC)(NTota1-Conn)

It's this additional resistance that is a concern when maintaining the UFSAR minimum voltage requirement (105 VDC. 210 VDC). If this resistance becomes high enough, the extra loading it produces would remove the remaining capacity in the battery and cause the battery terminal voltage to drop below the minimum requirement.

The ELMS-DC program will be used to determine the total allowable battery string resistance based on the remaining battery capacity of each of the six safety related batteries. The following steps will be used for each battery to determine this maximum allowable resistance:

1. From references 2 and 3, the latest ELMS-DC files will be identified for each battery.

2. From the applicable ELMS-DC file, the "Minimum Battery Voltage" will be increased slightly until a positive remaining battery capacity (just above 0%) is found. The voltage that produces this result will be designated as VMin. The difference between VM1n and the minimum required voltage, VReqUired (e.g. 105 VDC) is the amount of margin that exists to mitigate any increase resistance due to corrosion. This value will be designated as Vx.

Therefore, V x = V Min - V Required

3. From reference 1, the battery manufacturer allows for a 0.020 volt drop across each intercell, and inteNack connection. From references 2 and 3, both the 125 VDC and 250 VDC batteries utilize NCN-21 cells manufactured by GNB. From the data sheet for these batteries (Ref. 27, page B3), the NCN-21 cells have a 1-hour discharge rate of 750 amps when discharged to 1.75 volts/cell. From Ohm's Law, the cell manufacturer's design intercell resistance is, R

4. To determine the total resistance accounted for in the vendor discharge curves, the intercell resistance RIc will be multiplied by the number of intercell connectors, inter-rack connections, and the feed cable to lug connections. Since the vendor assumes the same voltage drop for each type of connection, the various connections will be combined into a single sum.

5. The added allowable resistance due to the remaining margin in the battery is found from Ohm's Law,

where, Vx = Voltage difference calculated in step 2 IMA = Maximum current from duty cycle.

6. The total allowable measured resistance, RTotal-Allow, is the sum of the vendor allowable resistance plus the extra allowable resistance due to the remaining battery capacity minus the jumper cable resistance and micro-ohm meter inaccuracies.

Note that the measurements taken at the inter-rack connection points will not include the resistance of the jumper cables that extend between the tiers and racks (Ref. 13).

The resistance values of the jumper cables (Rjumper) must be subtracted from the calculated value to obtain an accurate total allowable resistance. In addition, inaccuracies associated with the micro-ohm meter can affect the results. These inaccuracies, designated as RMeter, will also be subtracted (conservative). Note that RVendor and Rjumper will be corrected for temperature as the battery rooms are assumed to be at 120°F per Assumption 2. RTotal-Allow is the value that must be met to ensure the UFSAR required minimum voltage is maintained.

Acceptance Criteria This calculation uses the ELMS-DC program in conjunction with numerical analysis to determine the maximum allowable resistance of the 125 VDC and 250 VDC Safety Related Batteries.

These values are the maximum resistances that are allowed to ensure the UFSAR required voltages of 105 VDC and 210 VDC for the 125 and 250 VDC batteries are maintained. However, battery loading can change over time due to the installation of modifications which can either increase or decrease the battery's remaining capacity. For that reason, the absolute maximum allowable resistance will not be used as the acceptance criteria for the Technical Specification surveillances.

To allow for future load growth, resistance values chosen must be below the absolute maximum values (RTotal-Allow), yet be above the values that would be obtained from the periodic field measurements under normal conditions. Baseline resistances for the subject batteries are contained in the data collection forms used with procedure QCEPM 0100-01 (Ref. 21-26). This baseline data was obtained at the time of battery installation. Per Reference 13, maintenance is performed on any connection that exceeds 120% of the baseline resistance. The lower bound of the acceptance criteria will, therefore, be 120% of the summation of all the baseline resistances listed in References 21-26 for the applicable battery. The upper bound will be conservatively chosen such that it remains below the absolute maximum values.

These values are the maximum resistances that are allowed to ensure the UFSAR required voltages of 105 VDC and 210 VDC for the 125 and 250 VDC batteries are maintained.

1. The 125 VDC Alternate Batteries for Unit 1 and 2 utilize the same cell type and load profiles as the Normal 125 VDC Batteries. The Alternate batteries are also enveloped by the Normal batteries in regards to the length of the jumper cables and the number and type of connections. The acceptance criteria for the Unit 1(2) 125 VDC Alternate batteries will be the same as the Unit 1(2) Normal 125 VDC batteries. This is verified from references 2, 3, 4, 5, 6 and 14.

2. The ambient temperature in the battery rooms affects the resistance values of the intercell connectors and inter-rack jumper cables. Per UFSAR Section 9.4.4, the maximum temperature in the turbine building is 120°F. As such, a bounding temperature value of 120°F will be used when calculating intercell connector and jumper cable resistance values. This assumption is conservative as copper resistance increases with an increase in temperature, and battery room temperatures are normally well below this maximum temperature. Note that the effects of elevated temperatures on battery life are monitored via performance and modified performance tests conducted per the associated Technical Specifications Surveillance Requirements.

Design Inputs 1.

From Reference 14, the battery jumper cables consist of 4 single conductors in parallel.

From Reference 16, the DC resistance for the inter-rack jumper cables is as follows:

250 MCM = 0.044912/1000' (at 25°C) 350 MCM = 0.0320 011000' (at 25°C) 2.

Micro-ohm meter accuracy = 0.2% +/- 0.2 µS2 of full scale (Ref. 15) (Attachment D) 3.

All batteries utilize GNB NCN-21 cells (Ref. 2, 3) 4.

The baseline resistance values for the subject batteries were summed and are contained in Table 1. Baseline values were obtained at the time of battery installation.

1. Jumper Cable (inter-rack and inter-tier) Resistance From Design Input 1, the battery jumper cables have the following resistances:

250 MCM = 0.0449 52/1000' (at 25°C) 350 MCM = 0.03200/1000' (at 25°C)

Per Assumption 2, the cable resistance must be adjusted for worst-case conditions which is 120°F. The above resistance values will be adjusted to 120°F using Temperature Conversion Table 9-3 and Resistance Temperature Correction Factors Table 1-4 ( Ref.

16). The 120°F temperature value converts to 50°C per Table 9-3 From Table 1-4, using a correction factor of 1.096, the above resistance values become:

250 MCM = 0.0492 52/1000' (at 50°C) 350 MCM = 0.0351 f2/1000' (at 50°C)

The following is a tabulation of the total resistance due to the jumper cables for each battery. Note that from Design Input 1, the jumpers are actually 4-1/C cables in parallel.

Micro-Ohm Meter Inaccuracies.

To determine the resistance of the entire battery string, a micro-ohm meter will be used to measure the resistance of each intercell connector and then summed. This sum, however, will contain an uncertainty error due to the reference accuracy (RA) of the meter. Per Design Input 2, the RA of the meter is 0.2% (full scale) +/- 0.2 pfl. The total uncertainly due to meter reading is found from the following equation (Ref. 28). The number of meter readings is from Table 2 with two measurements per jumper cable (one measurement at each end).

Z = +/- (A2 + B2 + C2+...)112

where, A, B, C, etc. are the measurement uncertainties for each intercell and jumper connection.

Table 5 is a summary of these results along with acceptance criteria to be used in the Technical Specification surveillances. Note that the acceptance criteria are lower than the calculated total allowable resistances. This adds conservatism and allows for changes in battery loading to occur without revising the Technical Specifications. The results of this calculation are based on the methodologies and assumptions described in this calculation.
