Attachment 1 L-20-251 Response to Request for Additional Information Page 1 of 8 By letter dated April 24, 2020 (Accession No. ML20115E517), Energy Harbor Nuclear Corp. submitted a license amendment request (LAR) for Nuclear Regulatory Commission (NRC) review and approval. By electronic mail dated August 14, 2020 (Accession No. ML20227A371), NRC staff requested additional information to complete its review. The request for additional information (RAI) is presented in bold type, followed by the Energy Harbor Nuclear Corp. response.

RAI-EEOB-01 Section 2.2, Verifications and Required Updated Safety Analyses Report

[UFSAR] Changes, of the LAR, the licensee stated that the PNPP Updated Safety Analysis Report will be revised to include, How a 15 percent design margin for the batteries corresponds to a 2 amp float current value indicating that the battery is 92 percent charged for Division 1, 96 percent charged for Division 2, and 95 percent charged for Division 3.

Regarding the selection of float current limit (or return to service limit), TSTF-500 states:

One method of selecting the return to service limit that has been accepted by the NRC is reserving [5%] of the available design margin above that required to perform the intended design function.

The selected float current limit provides an indication that the battery is less than 100 percent charged, therefore the [5%] design margin is maintained to provide assurance that the battery is fully charged to perform its design safety function when the float current limit is reached.

The NRC staff notes that the licensee does not discuss how the 15 percent design margin would ensure that the PNPP batteries would be fully charged at a 2-amp float current.

Explain how maintaining a 15 percent design for the batteries will ensure that the batteries are fully charged (i.e., capable of performing their design function) when the 2-amp float current limit is reached.

Response

For Division 1:

The battery is sized to account for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 300.02 amp-hours (AH) of the batterys 1260 AH nameplate rating, which equates to a 24 percent capacity discharge. Per the L-20-251 Page 2 of 8 manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 92 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event.

For Division 2:

The battery is sized accounting for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 262.18 AH of the batterys 1260 AH nameplate rating, which equates to a 21 percent capacity discharge. Per the manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 96 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event.

For Division 3:

The battery is sized accounting for a 1.25 aging factor and a 1.15 design margin. The entire 120-minute design basis scenario uses 56.99 AH of the batterys 250 AH nameplate rating, which equates to a 23 percent capacity discharge. Per the manufacturer, reduced capacity at the start of the design basis event due to the use of the 2-amp charging current criteria equaling 95 percent is acceptable. A battery at that capacity will still have ability to supply all required design basis loads for the 2-hour event.

Therefore, maintaining a 15 percent design for the batteries will ensure that the batteries are fully charged when the 2-amp float current limit is reached.

RAI-EEOB-02 In Attachment 2 of the LAR, the licensee proposed the following new TS 3.8.4 Condition B:

Condition B Required battery on one subsystem inoperable.

Required Action B.1 Restore battery to operable status.

Completion Time 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months The licensee proposed to revise existing Condition A and renumber it Condition C, as follows:

Condition C Division 1 or 2 DC electrical power subsystem inoperable for reasons other than Condition A or B.

L-20-251 Page 3 of 8 Required Action C.1 Restore Division 1 and 2 DC electrical power subsystems to operable status.

Completion Time 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months The Reviewer Note for TSTF-500 Section 3.8.4 Required Action B.1 stated that Condition B (One [or two] batter[y][ies on one subsystem] inoperable) is included if Required Action B.1 and Required Action C.1 for Condition C (One DC electrical power subsystem inoperable for reasons other than Condition A [or B]) would have different completion times. If the plant design supports different completion times when a battery is inoperable, but the charger is operable, then Condition B is used. If not, Condition B is deleted, and only Condition C is used.

The NRC staff notes that the proposed completion time for an inoperable required battery on one subsystem (new Condition B in LAR) is the same as the completion time for an inoperable required battery with operable battery charger (revised Condition C in LAR). Thus, based on the above Reviewer Note in TSTF-500, the proposed new Condition B with associated Required Action B.1 and completion time should not be adopted.

Justify the deviation from the TSTF-500 for adoption of new Condition B and Required Action B.1 with the same 2-hour completion time as for Required Action C.1.

Response

The PNPP completion times when a battery is inoperable are the same for Technical Specification (TS) 3.8.4 Condition B and Condition C; therefore, Condition B is being deleted. New TS and TS Bases pages are provided to replace those submitted with the original LAR.

RAI-EEOB-03 TS 3.8.4, DC Sources - Operating, limiting condition for operation (LCO) requires the Division 1, Division 2, and Division 3 DC electrical power subsystems shall be OPERABLE, with each subsystem consisting of either the Unit 1 or Unit 2 battery, either the normal or reserve battery charger, and the corresponding control equipment and interconnecting cabling supplying power to the associated bus within the division.

The licensee proposed a new alternate testing for a battery charger in revised SR 3.8.4.2 Verify each battery charger can recharge the battery to the fully charged state within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months while supplying the largest combined demands of the various continuous steady state loads, after a L-20-251 Page 4 of 8 battery discharge to the bounding design basis event discharge state.

UFSAR Section 8.3.2.1.2.2, Capacity, states: The battery chargers are sized to supply the continuous load of both units while simultaneously recharging the battery to a fully charged condition from the design minimum charge of 1.875 volts/cell for Division 1 and 1.863 volts/cell for Division 2 within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

UFSAR Section 8.3.2.1.3.5, Battery Capacity, states: The Division 3 battery charger is capable of recharging the Division 3 battery from a fully discharged condition in eight hours while also supplying the steady-state dc bus loads.

The NRC staff notes that the above UFSAR sections do not discuss 24-hour charging capability for the Division 1, 2, or 3 battery charger, as proposed in revised SR 3.8.4.2.

Explain the basis for the proposed 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months in SR 3.8.4.2 for the PNPP battery charger.

Response

The proposed 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months is replaced with 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months for Divisions 1 and 2, and 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months for Division 3. Therefore, the proposed Surveillance Requirement (SR) 3.8.4.2 is revised to read as follows:

Verify each required Division 1 and 2 battery charger supplies 400 amps at 125 V for 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ; and each required Division 3 battery charger supplies 50 amps at 125 V for 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months .

OR Verify each battery charger can recharge the battery to the fully charged state within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months for Division 1 and 2 and 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months for Division 3 while supplying the largest combined demands of the various continuous steady state loads, after a battery discharge to the bounding design basis event discharge state.

New TS pages are provided to replace those submitted with the original LAR.

RAI-EEOB-04 The proposed new TS 3.8.6 Condition A would apply when one or two batteries on one subsystem is found with one or more battery cell(s) with a float voltage of less than 2.07 volts (V).

L-20-251 Page 5 of 8 The NRC staff notes that the 2.07-V for the battery cell float voltage is bracketed in TSTF-500. The battery cell float voltage limit should be greater than or equal to the battery open circuit cell voltage to ensure that the battery is not discharging.

A battery cell voltage below the open circuit cell voltage indicates that the cell is discharging. It appears that the basis for the proposed 2.07-V limit for the PNPP battery cell float voltage was not provided.

Discuss the basis for the 2.07-V limit for the PNPP battery cell float voltage. In the discussion, provide the batteries open circuit cell voltages.

Response

At PNPP, the battery is designed and sized to support all design basis loads and duty cycle whenever battery Category C limits are as defined by the current approved TS Table 3.8.6-1. The Category C limit for float voltage is 2.07 V per individual cell. This would equate to an open circuit voltage of 126.27 VDC for Division 1 and 124.2 VDC for Divisions 2 and 3 batteries. As such, the use of the 2.07 V limit as part of TSTF-500 is not a change from the existing PNPP TS open circuit cell voltage requirement.

RAI-EEOB-05 The licensee proposed to relocate current SR 3.8.4.8 from TS 3.8.4 to TS 3.8.6 and renumber it as SR 3.8.6.6. The modified performance discharge test in TSTF-500 is adopted for the proposed SR 3.8.6.6 and the note stating credit may be taken for unplanned event that satisfy this SR in the current SR 3.8.4.8 is not added to SR 3.8.6.6.

The TSTF-500 states: The licensee must confirm that the modified performance discharge test completely encompasses the load profile of the battery service test and that it adequately confirms the intent of the service test to verify the battery capacity to supply the design basis load profile.

The NRC staff notes that the LAR does not discuss the adequacy of the modified performance discharged for the PNPP batteries and the exclusion of the current SR 3.8.4.8 note from SR 3.8.6.6.

a. Confirm that the modified performance discharge test completely encompasses the load profile of the battery service test and that it adequately confirms the intent of the service test to verify the battery capacity to supply the design basis load profile.

b. Explain why the note in SR 3.8.4.8 was not added to SR 3.8.6.6.

L-20-251 Page 6 of 8

Response

Energy Harbor Nuclear Corp. does not intend to develop a (battery) modified performance discharge test; therefore, all references to the modified performance discharge test are being removed from TS SR 3.8.6.6 and TS Bases 3.8.6.

Energy Harbor Nuclear Corp. reviewed the purpose of the note in SR 3.8.4.8 and determined that the note does belong in SR 3.8.6.6. As a result, new TS and TS Bases pages are provided to replace those submitted with the original LAR. The new pages include the note.

While preparing this RAI response, it was identified that during the relocation of SR 3.8.4.8 to SR 3.8.6.6, the word capacity was inadvertently changed to capability.

This has been corrected in new TS page provided.

RAI-EEOB-06 The licensee proposed adding a new TS 3.8.6 Condition D which would apply to one or two battery (ies) on one subsystem with a pilot cell electrolyte temperature less than the minimum established design limits. The Required Action D.1 would restore the battery pilot cell temperature to greater than or equal to minimum established design limits within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

In Enclosure A of the LAR, the licensee states:

Energy Harbor Nuclear Corp. verifies that battery room temperature is routinely monitored such that a room temperature excursion could reasonably expect to be detected and corrected prior to the average battery electrolyte temperature dropping below the minimum electrolyte temperature.

Regarding the selection of pilot cells, the TSTF-500 states:

Previously, average battery temperature was monitored instead of pilot cell temperature. As a result, temperature was not a criterion with selecting a pilot cell. In order to use pilot cell temperature instead of the average battery temperature, temperature must be used as a criterion when selecting the pilot cell. [] For batteries where it could be shown that the maximum temperature deviation across the battery did not exceed the IEEE 450 recommended maximum of 5°F [degrees Fahrenheit], the NRC has accepted that the cell temperature was not a critical parameter. Therefore, for these batteries, cell temperature did not have to be taken into account when selecting pilot cells.

L-20-251 Page 7 of 8 The NRC staff notes that the LAR does not discuss 1) the frequency of monitoring the battery room and how the battery room temperature would be restored if it was outside the temperature design limits, and 2) the selection of the battery pilot cell based on temperature.

a. Provide a discussion about how the battery rooms temperatures are monitored and provide the minimum frequencies at which the temperatures are monitored. Also explain how the licensee would restore the vital and DG battery rooms temperatures if they were outside the temperature design limits.

b. Provide a discussion about the selection of the battery pilot cell based on temperature. If the temperature will not be used as a criterion for selecting battery pilot cells, provide an analysis of temperature deviations for the batteries based on operation experience to show that the maximum temperature deviation across the batteries does not exceed the IEEE 450 recommended maximum of 5°F.

Response

At PNPP, battery room temperatures are monitored and recorded every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months by the control room operator during equipment rounds. At 74°F, which is 2°F above the minimum, action is initiated. Restoration of temperature would include actions such as adjusting thermostats, verifying proper ventilation operation, and energizing duct heaters where installed.

PNPP does not select a pilot cell for routine monitoring based on individual cell temperature. Historical data dating back to 2013 was reviewed for all six divisional batteries at PNPP. At no time was a battery cell found to deviate more than 5°F. PNPP experience has demonstrated that battery cell temperature deviation from the average has not occurred. The phenomena of increased battery cell temperature is typically caused by battery cell shorting conditions, which are detectable by individual cell voltage measurements. Individual cell voltage is monitored under routine surveillance tasks and issues identified requiring corrective measures would be performed per recommendations in Section 4.4 of IEEE 450. Selection of the pilot cell is on a rotating basis at PNPP, and this method ensures a representative sample of cells is monitored instead of continuing to monitor a single cell that may have internal degradation. This provides a more accurate representation of the respective battery condition.

RAI-EEOB-07 In Enclosure A of the LAR, the licensee proposed relocating the TS Table 3.8.6-1, Battery Surveillance Requirements, to a licensee-controlled program. The Table 3.8.6-1 includes Category A, B, and C limits for the battery cell parameters (i.e., electrolyte level, float voltage, specific gravity).

L-20-251 Page 8 of 8 Confirm that the battery cell parameters (electrolyte level, float voltage, specific gravity) will continue to be controlled at their current Categories A, B, and C levels in the licensee-controlled program, and that actions to restore deficient values will be implemented in accordance with the licensees corrective action program.

Response

Energy Harbor Nuclear Corp. confirms the battery cell parameters will continue to be controlled at the current PNPP Categories A, B, and C levels in the licensee-controlled program. Deficient values will be documented in the corrective action program and appropriate actions taken to restore the values.

TS BASES - PROVIDED FOR CONTEXT - NO CHANGES - DC Sources - Operating INFORMATION ONLY B 3.8.4 B 3.8 ELECTRICAL POWER SYSTEMS B 3.8.4 DC Sources - Operating BASES BACKGROUND The station DC electrical power system provides the AC emergency power system with control power. It also provides both motive and control power to selected safety related equipment. As required by 10 CFR 50, Appendix A, GDC 17 (Ref. 1), the DC electrical power system is designed to have sufficient independence, redundancy, and testability to perform its safety functions, assuming a single failure. The DC electrical power system also conforms to the requirements of Regulatory Guide 1.6 (Ref. 2) and IEEE-308 (Ref. 3).

The 125 VDC electrical power system consists of three independent Class 1E DC electrical power subsystems, Divisions 1, 2, and 3. Each subsystem consists of a battery, a battery charger, a reserve battery charger, and all the associated control equipment and interconnecting cabling. In addition, the ability exists to tie in the Unit 2 batteries in each division to their respective Unit 1 buses.

During normal operation, the DC loads are powered from the battery chargers with the batteries floating on the system. In case of loss of normal power to the battery charger, the DC loads are automatically powered from the Engineered Safety Feature (ESF) batteries.

Each of the Division 1 and 2 electrical power subsystems provides the control power for its associated Class 1E AC power load group, 4.16 kV switchgear, and 480 V load centers. The Division 3 DC electrical power subsystem provides DC motive and control power as required for the High Pressure Core Spray (HPCS) System diesel generator (DG) set control and protection.

The DC power distribution system is described in more detail in Bases for LCO 3.8.7, Distribution Systems - Operating, and LCO 3.8.8, Distribution Systems - Shutdown.

TS BASES MARK-UP - PROVIDED DC Sources - Operating FOR INFORMATION ONLY B 3.8.4 BASES BACKGROUND Each Division 1, 2 and 3 battery has adequate storage capacity to carry (continued) the required load continuously for at least 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months as discussed in the USAR, Section 8.3.2 (Ref. 4).

The Division 3 battery has adequate storage to carry the required load continuously for at least 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months (Ref. 4).

Each DC subsystem is located in an area separated physically and electrically from the other subsystems to ensure that a single failure in one subsystem does not cause a failure in a redundant subsystem.

There is no sharing between redundant Class 1E subsystems such as batteries, battery chargers, or distribution panels.

Each battery has adequate storage capacity to meet the duty cycles discussed in the USAR, Section 8 (Ref. 4). The battery is designed with additional capacity above that required by the design duty cycle to allow for temperature variations and other factors.

The batteries for a DC electrical power subsystem are sized to produce required capacity at 80% of nameplate rating. The minimum voltage design limit is 1.875 V per cell for Division 1, 1.863 V per cell for Division 2 and 1.905 V per cell for Division 3 batteries (Ref. 4).

The battery cells are flooded lead acid construction with a nominal specific gravity of 1.215. This specific gravity corresponds to an open circuit battery voltage of approximately 125 V for a 61 cell battery for Division 1 and a 60 cell battery for Division 2 and Division 3 (i.e., cell voltage of 2.049 volts per cell (Vpc) for Division 1 and cell voltage of 2.083 Vpc for Division 2 and Division 3)). The open circuit voltage is the voltage maintained when there is no charging or discharging. Once fully charged with its open circuit voltage 2.049 Vpc, the Division 1 battery cell will maintain its capacity for 30 days without further charging per manufacturers instructions. Likewise, once fully charged with its open circuit voltage 2.083 Vpc, the Division 2 battery cell and Division 3 battery cell will maintain its capacity for 30 days without further charging per manufacturers instructions. Optimal long term performance, however, is obtained by maintaining a float voltage 2.20 to 2.25 Vpc. This provides adequate over-potential, which limits the formation of lead sulfate and self-discharge. The nominal float voltage of 2.21 Vpc for Division 1 and 2.25 Vpc for Division 2 and Division 3 corresponds to a total float voltage output of 135 V for a 61/60 cell battery as discussed in the USAR, Section 8 (Ref. 4).

Each battery charger of Division 1 and 2 DC electrical power subsystems battery charger has ample power output capacity for the steady state operation of connected loads required during normal operation, while at the same time maintaining its battery bank fully charged. Each battery charger has sufficient excess capacity to restore the battery bank from PERRY - UNIT 1 B 3.8-52 Revision No. 9

TS BASES MARK-UP - PROVIDED DC Sources - Operating FOR INFORMATION ONLY B 3.8.4 the design minimum charge to its fully charged state within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months while supplying normal steady state loads (Ref. 4).

The battery charger of Division 3 DC electrical power subsystem battery charger has sufficient excess capacity to restore the battery bank from the design minimum charge to its fully charged state in 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months while supplying normal steady state loads (Ref. 4).

The battery charger is normally in the float-charge mode. Float-charge is the condition in which the charger is supplying the connected loads and the battery cells are receiving adequate current to optimally charge the battery. This assures the internal losses of a battery are overcome and the battery is maintained in a fully charged state.

When desired, the charger can be placed in the equalize mode. The equalize mode is at a higher voltage than the float mode and charging current is correspondingly higher. The battery charger is operated in the equalize mode after a battery discharge or for routine maintenance.

Following a battery discharge, the battery recharge characteristic accepts current at the current limit of the battery charger (if the discharge was significant, e.g., following a battery performance test) until the battery terminal voltage approaches the charger voltage setpoint. Charging current then reduces exponentially during the remainder of the recharge cycle. Lead-calcium batteries have recharge efficiencies of greater than 95%, so once at least 105% of the ampere-hours discharged have been returned, the battery capacity would be restored to the same condition as it was prior to the discharge. This can be monitored by direct observation of the exponentially decaying charging current or by evaluating the amp-hours discharged from the battery and amp-hours returned to the battery.

TS BASES - PROVIDED FOR CONTEXT - NO CHANGES - DC Sources - Operating INFORMATION ONLY B 3.8.4 BASES APPLICABLE The OPERABILITY of the DC subsystems is consistent with the initial SAFETY assumptions of the accident analyses and is based upon meeting the ANALYSES design basis of the unit. This includes maintaining DC sources (continued) OPERABLE during accident conditions in the event of:

a. An assumed loss of all offsite AC power or of all onsite AC power; and

b. A worst case single failure.

The DC sources satisfy Criterion 3 of the NRC Final Policy Statement on Technical Specification Improvements (58 FR 39132).

LCO The DC electrical power subsystems, each subsystem consisting of either the Unit 1 or 2 battery, either the normal or reserve battery charger, and the corresponding control equipment and interconnecting cabling supplying power to the associated bus within the divisions, are required to be OPERABLE to ensure the availability of the required power to shut down the reactor and maintain it in a safe condition after an anticipated operational occurrence (AOO) or a postulated DBA. Loss of any DC electrical power subsystem does not prevent the minimum safety function from being performed (Ref. 4).

Division 1 consists of:

1. 125 volt battery 1R42-S002 or 2R42-S002.

2. 125 volt full capacity charger 1R42-S006 or 0R42-S007.

Division 2 consists of:

APPLICABILITY The DC electrical power sources are required to be OPERABLE in MODES 1, 2, and 3 to ensure safe unit operation and to ensure that:

ACTIONS A.1, A.2, and A.3 Condition A represents one subsystem with required battery charger inoperable (e.g., the voltage limit of SR 3.8.4.1 is not maintained). The ACTIONS provide a tiered response that focuses on returning the battery to the fully charged state and restoring a fully qualified charger to OPERABLE status in a reasonable time period. Required Action A.1 requires that the battery terminal voltage be restored to greater than or equal to the minimum established float voltage within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months . This time provides for returning the inoperable charger to OPERABLE status or providing an alternate means of restoring battery terminal voltage to greater than or equal to the minimum established float voltage. Restoring the battery terminal voltage to greater than or equal to the minimum established float voltage provides good assurance that, within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , the battery will be restored to its fully charged condition (Required Action A.2) from any discharge that might have occurred due to the charger inoperability.

A discharged battery having terminal voltage of at least the minimum established float voltage indicates that the battery is on the exponential charging current portion (the second part) of its recharge cycle. The time to return a battery to its fully charged state under this condition is simply a function of the amount of the previous discharge and the recharge characteristic of the battery. Thus there is good assurance of fully recharging the battery within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , avoiding a premature shutdown with its own attendant risk.

If established battery terminal float voltage cannot be restored to greater than or equal to the minimum established float voltage within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , and the charger is not operating in the current-limiting mode, a faulty charger is indicated. A faulty charger that is incapable of maintaining established battery terminal float voltage does not provide assurance that it can revert to and operate properly in the current limit mode that is necessary during the recovery period following a battery discharge event that the DC system is designed for.

If the charger is operating in the current limit mode after 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months that is an indication that the battery is partially discharged and its capacity margins will be reduced. The time to return the battery to its fully charged condition in this case is a function of the battery charger capacity, the amount of loads on the associated DC system, the amount of the PERRY - UNIT 1 B 3.8-54 Revision No. 1

TS BASES MARK-UP - PROVIDED DC Sources - Operating FOR INFORMATION ONLY B 3.8.4 previous discharge, and the recharge characteristics of the battery. The charge time can be extensive, and there is not adequate assurance that it can be recharged within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months (Required Action A.2).

Required Action A.2 requires that the battery float current be verified as less than or equal to 2 amps. This indicates that, if the battery had been discharged as a result of the inoperable battery charger, it is now fully capable of supplying the maximum expected load requirement. The 2 amp value is based on returning the battery for Division 1 to 92%

charge, the battery for Division 2 to 96% charge, and the battery for Division 3 to 95% charge, and assumes a 5% design margin for the battery. If at the expiration of the initial 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months period the battery float current is not less than or equal to 2 amps this indicates there may be additional battery problems and the battery must be declared inoperable.

Required Action A.3 limits the restoration time for the inoperable battery charger to 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . This action is applicable if an alternate means of restoring battery terminal voltage to greater than or equal to the minimum established float voltage has been used (e.g., balance of plant non-Class 1E battery charger). The 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months Completion Time reflects a reasonable time to effect restoration of the qualified battery charger to OPERABLE status.

BA.1 Condition BA represents one division subsystem with a loss of ability to completely respond to an event, and a potential loss of ability to remain energized during normal operation. It is, therefore, imperative that the operators attention focus on stabilizing the unit, minimizing the potential for complete loss of DC power to the affected division subsystem. The 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months limit is consistent with the allowed time for an inoperable DC distribution system division subsystem.

If one of the required Division 1 or 2 DC electrical power subsystems is inoperable for reasons other than Condition A (e.g., both Unit 1 and 2 batteries inoperable, normal and reserve battery chargers inoperable, or both batteries and chargers inoperableinoperable battery charger and associated inoperable battery), the remaining DC electrical power subsystems have the capacity to support a safe shutdown and to mitigate an accident condition. Since a subsequent worst case single failure could, however, result in the loss of minimum necessary DC electrical subsystems, continued power operation should not exceed 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months . The 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months Completion Time is based on Regulatory Guide 1.93 (Ref. 7) and reflects a reasonable time to assess unit status as a function of the inoperable DC electrical power subsystem and, if the DC electrical power subsystem is not restored to OPERABLE status, to prepare to effect an orderly and safe unit shutdown.

If the DC electrical power subsystem cannot be restored to OPERABLE status within the associated Completion Time, the unit must be brought to a MODE in which the LCO does not apply.

The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems. The Completion Time to bring the unit to MODE 4 is consistent with the time required in Regulatory Guide 1.93 (Ref. 7).

SURVEILLANCE SR 3.8.4.1 REQUIREMENTS Verifying battery terminal voltage while on float charge helps to ensure the effectiveness of the battery chargers, which support charging system and the ability of the batteries to perform their intended function. Float charge is the condition in which the charger is supplying the continuous charge required to overcome the internal losses of a battery (or battery cell) and maintain the battery (or battery cell) in a fully charged state while supplying the continuous steady state loads of the associated DC subsystem. On float charge, battery cells will receive adequate current to optimally charge the battery. The voltage requirements are based on the nominal design voltage of the battery and are consistent with the minimum float voltage established by the battery manufacturer 2.20 Vpc times the number of connected cellsinitial voltages assumed in the battery sizing calculations. This voltage maintains the battery plates in a condition that supports maintaining the grid life. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.8.4.2 Visual inspection to detect corrosion of the battery connections, or measurement of the resistance of each inter-cell, inter-rack, inter-tier, and terminal connection, provides an indication of physical damage or abnormal deterioration that could potentially degrade battery performance.

TS BASES MARK-UP - PROVIDED FOR INFORMATION ONLY DC Sources - Operating B 3.8.4 BASES SURVEILLANCE SR 3.8.4.62 REQUIREMENTS (continued) This SR verifies Battery charger capability requirements are based on the design capacity of the battery chargers (Ref. 4). According to Regulatory Guide 1.32 (Ref. 89), the battery charger supply is requiredrecommended to be based on the largest combined demands of the various steady state loads and the charging capacity to restore the battery from the design minimum charge state to the fully charged state, irrespective of the status of the unit during these demand occurrences. The minimum required amperes and duration ensure that these requirements can be satisfied.

This SR provides two options. One option requires that each battery charger be capable of supplying 400 amps for Division 1 and 2 and 50 amps for Division 3 at the minimum established float voltage for 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months . The ampere requirements are based on the output rating of the chargers. The voltage requirements are based on the charger voltage level after a response to a loss of AC power. The time period is sufficient for the charger temperature to have stabilized and to have been maintained for at least 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

The other option requires that each battery charger be capable of recharging the battery after a performance test coincident with supplying the largest coincident demands of the various continuous steady state loads (irrespective of the status of the plant during which these demands occur). This level of loading may not normally be available following the battery performance test and will need to be supplemented with additional loads. The duration for this test may be longer than the charger sizing criteria since the battery recharge is affected by float voltage, temperature, and the exponential decay in charging current. The battery is recharged when the measured charging current is 2 amps.

The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.8.4.73 A battery service test is a special test of the batterys capability, as found, to satisfy the design requirements (battery duty cycle) of the DC electrical power system. The discharge rate and test length correspond to the design duty cycle requirements as specified in Reference 4.

The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

This SR is modified by a Note. The Note allows the periodic performance of SR 3.8.6.64.8 in lieu of SR 3.8.4.37. This substitution is acceptable because SR 3.8.6.64.8 represents a more severe test of battery capacity than SR 3.8.4.37.

The test is intended to determine overall battery degradation due to age and usage.

The acceptance criteria for this Surveillance is consistent with IEEE-450 (Ref. 8) and IEEE-485 (Ref. 11). These references recommend that the battery be replaced if its capacity is below 80% of the manufacturers rating. A capacity of 80% shows that the battery rate of deterioration is increasing, even if there is ample capacity to meet the load requirements.

The Surveillance Frequency for this test is normally performed in accordance with the Surveillance Frequency Control Program. If the battery shows degradation, or if the battery has reached 85% of its expected life and capacity is < 100% of the manufacturers rating, the Surveillance Frequency is reduced to 12 months. However, if the battery shows no degradation but has reached 85% of its expected life, the Surveillance Frequency is only reduced to 24 months for batteries that retain capacity 100% of the manufacturers rating. Degradation is indicated, according to IEEE-450 (Ref. 8), when the battery capacity drops by more than 10% relative to its capacity on the previous performance test or when it is 10% below the manufacturers rating. All these Frequencies are consistent with the recommendations in IEEE-450 (Ref. 8). This SR is modified by a Note. Credit may be taken for unplanned events that satisfy this SR. This note is provided to prevent unnecessary cycling of plant equipment.

d. Instrumentation and control capability is available for monitoring and maintaining the unit in a cold shutdown condition or refueling condition.

The DC electrical power requirements for MODES 1, 2, and 3 are covered in LCO 3.8.4.

ACTIONS The ACTIONS are modified by a Note indicating that LCO 3.0.3 does not apply. If moving recently irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of recently irradiated fuel assemblies is not sufficient reason to require reactor shutdown.

A.1, A.2, and A.3 Condition A represents one subsystem with required battery charger inoperable (e.g., the voltage limit of SR 3.8.4.1 is not maintained). The ACTIONS provide a tiered response that focuses on returning the battery to the fully charged state and restoring a fully qualified charger to OPERABLE status in a reasonable time period. Required Action A.1 requires that the battery terminal voltage be restored to greater than or equal to the minimum established float voltage within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months . This time provides for returning the inoperable charger to OPERABLE status or providing an alternate means of restoring battery terminal voltage to greater than or equal to the minimum established float voltage. Restoring the battery terminal voltage to greater than or equal to the minimum established float voltage provides good assurance that, within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , the battery will be restored to its fully charged condition (Required Action A.2) from any discharge that might have occurred due to the charger inoperability.

A discharged battery having terminal voltage of at least the minimum established float voltage indicates that the battery is on the exponential charging current portion (the second part) of its recharge cycle. The time to return a battery to its fully charged state under this condition is simply a function of the amount of the previous discharge and the recharge characteristic of the battery. Thus there is good assurance of fully recharging the battery within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , avoiding a premature shutdown with its own attendant risk.

If established battery terminal float voltage cannot be restored to greater than or equal to the minimum established float voltage within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , and the charger is not operating in the current-limiting mode, a faulty charger PERRY - UNIT 1 B 3.8-62 Revision No. 12- I

TS BASES MARK-UP - PROVIDED DC Sources - Shutdown FOR INFORMATION ONLY B 3.8.5 is indicated. A faulty charger that is incapable of maintaining established battery terminal float voltage does not provide assurance that it can revert to and operate properly in the current limit mode that is necessary during the recovery period following a battery discharge event that the DC system is designed for.

If the charger is operating in the current limit mode after 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months that is an indication that the battery is partially discharged and its capacity margins will be reduced. The time to return the battery to its fully charged condition in this case is a function of the battery charger capacity, the amount of loads on the associated DC system, the amount of the previous discharge, and the recharge characteristic of the battery. The charge time can be extensive, and there is not adequate assurance that it can be recharged within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months (Required Action A.2).

Required Action A.2 requires that the battery float current be verified as less than or equal to 2 amps. This indicates that, if the battery had been discharged as the result of the inoperable battery charger, it has now been fully recharged. If at the expiration of the initial 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months period the battery float current is not less than or equal to 2 amps this indicates there may be additional battery problems and the battery must be declared inoperable.

Required Action A.3 limits the restoration time for the inoperable battery charger to 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . This action is applicable if an alternate means of restoring battery terminal voltage to greater than or equal to the minimum established float voltage has been used (e.g., balance of plant non-Class 1E battery charger). The 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months Completion Time reflects a reasonable time to effect restoration of the qualified battery charger to OPERABLE status.

AB.1, AB.2.1, AB.2.2, and AB.2.3 If more than one DC distribution subsystem is required according to LCO 3.8.8, the DC subsystems remaining OPERABLE with one or more DC power sources inoperable may be capable of supporting sufficient required features to allow continuation of CORE ALTERATIONS and movement of recently irradiated fuel. By allowing the option to declare required features associated with an inoperable DC power source(s) inoperable, appropriate restrictions are implemented in accordance with the Required Actions of the LCOs for these associated required features.

Since this option may involve undesired administrative efforts, the allowance for sufficiently conservative alternate actions (i.e., to suspend CORE ALTERATIONS and movement of recently irradiated fuel assemblies in the primary containment and fuel handling building) is made.

Suspension of these activities shall not preclude completion of actions to establish a safe conservative condition. These actions minimize the probability of the occurrence of postulated events. It is further required to PERRY - UNIT 1 B 3.8-6 -

The Completion Time of immediately is consistent with the required times for actions requiring prompt attention. The restoration of the required DC electrical power subsystems should be completed as quickly as possible in order to minimize the time during which the plant safety systems may be without sufficient power.

SURVEILLANCE SR 3.8.5.1 REQUIREMENTS SR 3.8.5.1 requires performance of all Surveillances required by SR 3.8.4.1 through SR 3.8.4.83. Therefore, see the corresponding Bases for LCO 3.8.4 for a discussion of each SR.

This SR is modified by a Note. The reason for the Note is to preclude requiring the OPERABLE DC sources from being discharged below their capability to provide the required power supply or otherwise rendered inoperable during the performance of SRs. It is the intent that these SRs must still be capable of being met, but actual performance is not required.

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 B 3.8 ELECTRICAL POWER SYSTEMS B 3.8.6 Battery Cell Parameters BASES BACKGROUND This LCO delineates the limits on battery float current as well as electrolyte temperature, level, and float voltage, and specific gravity for the DC power source batteries. A discussion of these batteries and their OPERABILITY requirements is provided in the Bases for LCO 3.8.4, DC Sources - Operating, and LCO 3.8.5, DC Sources - Shutdown. In addition to the limitations of this Specification, the battery monitoring and maintenance program also implements a program specified in Specification 5.5.16 for monitoring various battery parameters.

The battery cells are of flooded lead acid construction with a nominal specific gravity of 1.215. This specific gravity corresponds to an open circuit battery voltage of approximately 125 V for 61 cell battery for Division 1 and a 60 cell battery for Division 2 and Division 3 (i.e., cell voltage of 2.049 volts per cell (Vpc) for Division 1 and cell voltage of 2.083 Vpc for Division 2 and 3)). The open circuit voltage is the voltage maintained when there is no charging or discharging. Once fully charged with its open circuit voltage 2.049 Vpc, the Division 1 battery cell will maintain its capacity for 30 days without further charging per manufacturers instructions. Likewise, once fully charged with its open circuit voltage 2.083 Vpc, the Division 2 battery cell and Division 3 battery cell will maintain its capacity for 30 days without further charging per manufacturers instructions. Optimal long term performance, however, is obtained by maintaining a float voltage 2.20 to 2.25 Vpc. This provides adequate over-potential which limits the formation of lead sulfate and self-discharge. The nominal float voltage of 2.21 Vpc for Division 1 and 2.25 Vpc for Division 2 and Division 3 corresponds to a total float voltage output of 135 V for a 61/60 cell battery as discussed in the USAR, Section 8 (Ref. 2).

APPLICABLE The initial conditions of Design Basis Accident (DBA) and transient SAFETY analyses in USAR, Chapter 6 (Ref. 13) and Chapter 15 (Ref. 24), assume ANALYSES that Engineered Safety Feature systems are OPERABLE. The DC electrical power subsystems provide normal and emergency DC electrical power for the diesel generators, emergency auxiliaries, and control and switching during all MODES of operation.

The OPERABILITY of the DC subsystems is consistent with the initial assumptions of the accident analyses and is based upon meeting the design basis of the unit. This includes maintaining at least one divisionsubsystem of DC sources OPERABLE during accident conditions, in the event of:

PERRY - UNIT 1 B 3.8-64 Revision No. 7

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6

a. An assumed loss of all offsite AC power or all onsite AC power; and

b. A worst case single failure.

Since battery cell parameters support the operation of the DC power sources, they satisfy Criterion 3 of the NRC Final Policy Statement on Technical Specification Improvements (58 FR 39132).

LCO Battery cell parameters must remain within acceptable limits to ensure availability of the required DC power to shut down the reactor and maintain it in a safe condition after an anticipated operational occurrence or a postulated DBA. Battery parameterElectrolyte limits are conservatively established, allowing continued DC electrical system function even with limits not met. Additional preventative maintenance, testing, and monitoring performed in accordance with the Battery Monitoring and Maintenance Program is conducted as specified in Specification 5.5.16.

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 BASES (continued)

APPLICABILITY The battery cell parameters are required solely for the support of the associated DC electrical power subsystem. Therefore, battery parameter limits are electrolyte is only required when the DC power source is required to be OPERABLE. Refer to the Applicability discussion in Bases for LCO 3.8.4 and LCO 3.8.5.

ACTIONS The ACTIONS Table is modified by a Note indicating that separate Condition entry is allowed for each battery. This is acceptable, since the Required Actions for each Condition provide appropriate compensatory actions for each inoperable battery. Complying with the Required Actions for one inoperable battery may allow for continued operation, and subsequent inoperable batteries are governed by separate Condition entry and application of associated Required Actions.

A.1, A.2, and A.3 With one or more cells in one or more batteries in one subsystem

< 2.07 V, the battery cell is degraded. Within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months verification of the required battery charger OPERABILITY is made by monitoring the battery terminal voltage (SR 3.8.4.1) and of the overall battery state of charge by monitoring the battery float charge current (SR 3.8.6.1). This assures that there is still sufficient battery capacity to perform the intended function.

Therefore, the affected battery is not required to be considered inoperable solely as a result of one or more cells in one or more batteries < 2.07 V, and continued operation is permitted for a limited period up to 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

Since the Required Actions only specify perform, a failure of SR 3.8.4.1 or SR 3.8.6.1 acceptance criteria does not result in this Required Action not met. However, if one of the SRs is failed the appropriate Condition(s),

depending on the cause of the failures, is entered. If SR 3.8.6.1 is failed then there is not assurance that there is still sufficient battery capacity to perform the intended function and the battery must be declared inoperable immediately.

B.1 and B.2 One or more batteries in one subsystem with float > 2 amps indicates that a partial discharge of the battery capacity has occurred. This may be due to a temporary loss of a battery charger or possibly due to one or more battery cells in a low voltage condition reflecting some loss of capacity.

Within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months verification of the required battery charger OPERABILITY is made by monitoring the battery terminal voltage. If the terminal voltage is found to be less than the minimum established float voltage there are two possibilities, the battery charger is inoperable or is operating in the current limit mode. Condition A addresses charger inoperability. If the charger is operating in the current limit mode after 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months that is an PERRY - UNIT 1 B 3.8-65 Revision No. 1

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 indication that the battery has been substantially discharged and likely cannot perform its required design functions. The time to return the battery to its fully charged condition in this case is a function of the battery charger capacity, the amount of loads on the associated DC system, the amount of the previous discharge, and the recharge characteristic of the battery. The charge time can be extensive, and there is not adequate assurance that it can be recharged within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months (Required Action B.2).

The battery must therefore be declared inoperable.

If the float voltage is found to be satisfactory but there are one or more battery cells with float voltage less than 2.07 V, the associated OR statement in Condition F is applicable and the battery must be declared inoperable immediately. If float voltage is satisfactory and there are no cells less than 2.07 V there is good assurance that, within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , the battery will be restored to its fully charged condition (Required Action B.2) from any discharge that might have occurred due to a temporary loss of the battery charger.

A discharged battery with float voltage (the charger setpoint) across its terminals indicates that the battery is on the exponential charging current portion (the second part) of its recharge cycle. The time to return a battery to its fully charged state under this condition is simply a function of the amount of the previous discharge and the recharge characteristic of the battery. Thus there is good assurance of fully recharging the battery within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , avoiding a premature shutdown with its own attendant risk.

If the condition is due to one or more cells in a low voltage condition but still greater than 2.07 V and float voltage is found to be satisfactory, this is not indication of a substantially discharged battery and 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months is a reasonable time prior to declaring the battery inoperable.

Since Required Action B.1 only specifies perform, a failure of SR 3.8.4.1 acceptance criteria does not result in the Required Action not met.

However, if SR 3.8.4.1 is failed, the appropriate Condition(s), depending on the cause of the failure, is entered.

C.1, C.2, and C.3 With one or more batteries in one subsystem with one or more cells electrolyte level above the top of the plates, but below the minimum established design limits, the battery still retains sufficient capacity to perform the intended function. Therefore, the affected battery is not required to be considered inoperable solely as a result of electrolyte level not met. Within 31 days the minimum established design limits for electrolyte level must be re-established.

With electrolyte level below the top of the plates there is a potential for dryout and plate degradation. Required Actions C.1 and C.2 address this potential (as well as provisions in Specification 5.5.16, Battery Monitoring PERRY - UNIT 1 B 3.8-65 Revision No. 1

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 and Maintenance Program). They are modified by a Note that indicates they are only applicable if electrolyte level is below the top of the plates.

Within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months level is required to be restored to above the top of the plates. The Required Action C.2 requirement to verify that there is no leakage by visual inspection and the Specification 5.5.16.b item to initiate action to equalize and test in accordance with manufacturers recommendation. They are performed following the restoration of the electrolyte level to above the top of the plates. Based on the results of the manufacturers recommended testing the batteries may have to be declared inoperable and the affected cells replaced.

D.1 With one or more batteries in one subsystem with pilot cell temperature less than the minimum established design limits, 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months is allowed to restore the temperature to within limits. A low electrolyte temperature limits the current and power available. Since the battery is sized with margin, while battery capacity is degraded, sufficient capacity exists to perform the intended function and the affected battery is not required to be considered inoperable solely as a result of the pilot cell temperature not met.

E.1 With one or more batteries in redundant subsystems with battery parameters not within limits there is not sufficient assurance that battery capacity has not been affected to the degree that the batteries can still perform their required function, given that redundant batteries are involved. With redundant batteries involved this potential could result in a total loss of function on multiple systems that rely upon the batteries. The longer Completion Times specified for battery parameters on non-redundant batteries not within limits are therefore not appropriate, and the parameters must be restored to within limits on at least one subsystem within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

A.1, A.2, and A.3 With parameters of one or more cells in one or more batteries not within limits (i.e., Category A limits not met, Category B limits not met, or Category A and B limits not met) but within the Category C limits specified in Table 3.8.6-1, the battery is degraded but there is still sufficient capacity to perform the intended function. Therefore, the affected battery is not required to be considered inoperable solely as a result of Category A or B limits not met, and continued operation is permitted for a limited period.

The pilot cell electrolyte level and float voltage are required to be verified to meet Category C limits within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months (Required Action A.1). This check provides a quick indication of the status of the remainder of the battery cells. One hour provides time to inspect the electrolyte level and to PERRY - UNIT 1 B 3.8-65 Revision No. 1

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 confirm the float voltage of the pilot cell. One hour is considered a reasonable amount of time to perform the required verification.

Verification that the Category C limits are met (Required Action A.2) provides assurance that, during the time needed to restore the parameters to the Category A and B limits, the battery is still capable of performing its intended function. A period of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months is allowed to complete the initial verification because specific gravity measurements (continued)

PERRY - UNIT 1 B 3.8-65 Revision No. 1

TS BASES MARK-UP - PROVIDED FOR INFORMATION ONLY Battery Cell Parameters B 3.8.6 BASES ACTIONS A.1, A.2, and A.3 (continued) must be obtained for each connected cell. Taking into consideration both the time required to perform the required verification and the assurance that the battery cell parameters are not severely degraded, this time is considered reasonable. The verification is repeated at 7 day intervals until the parameters are restored to Category A and B limits. This periodic verification is consistent with the normal Frequency of pilot cell surveillances.

Continued operation is only permitted for 31 days before battery cell parameters must be restored to within Category A and B limits. Taking into consideration that while battery capacity is degraded, sufficient capacity exists to perform the intended function and to allow time to fully restore the battery cell parameters to normal limits, this time is acceptable for operation prior to declaring the DC batteries inoperable.

FB.1 When any battery parameter is outside the allowances of the Required Actions for Condition A, B, C, D, or E, Category C limits for any connected cell, sufficient capacity to supply the maximum expected load requirement is not assured and the associated battery must be declared inoperable. Additionally, discovering one or more batteries in one subsystem with one or more battery cells float voltage less than 2.07 V and float current greater than 2 amps indicates that the battery capacity may not be sufficient to perform the intended functions. The battery must therefore be declared inoperable immediately. other potentially extreme conditions, such as not completing the Required Actions of Condition A within the required Completion Time or average electrolyte temperature of representative cells falling below 72°F, also are cause for immediately declaring the associated battery inoperable.

SURVEILLANCE SR 3.8.6.1 REQUIREMENTS Verifying battery float current while on float charge is used to determine the state of charge of the battery. Float charge is the condition in which the charger is supplying the continuous charge required to overcome the internal losses of a battery and maintain the battery in a charged state.

The equipment used to monitor float current must have the necessary accuracy and capability to measure electrical currents in the expected range. The float current requirements are based on the float current indicative of a charged battery. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

PERRY - UNIT 1 B 3.8-66 Revision No. 11

TS BASES MARK-UP - PROVIDED Battery Cell Parameters FOR INFORMATION ONLY B 3.8.6 This SR is modified by a Note that states the float current requirement is not required to be met when battery terminal voltage is less than the minimum established float voltage of SR 3.8.4.1. When this float voltage is not maintained the Required Actions of LCO 3.8.4 ACTION A are being taken, which provide the necessary and appropriate verifications of the battery condition. Furthermore, the float current limit of 2 amps is established based on the nominal float voltage value and is not directly applicable when this voltage is not maintained.

SR 3.8.6.2 and SR 3.8.6.5 Optimal long term battery performance is obtained by maintaining a float voltage greater than or equal to the minimum established design limits provided by the battery manufacturer, which corresponds to 135 V at the battery terminals, or 2.25 Vpc for a 60 cell battery and 2.21 Vpc for a 61 cell battery. This provides adequate over-potential, which limits the formation of lead sulfate and self discharge, which could eventually render the battery inoperable. Float voltages in this range or less, but greater than 2.07 Vpc, are addressed in Specification 5.5.16. SRs 3.8.6.2 and 3.8.6.5 require verification that the cell float voltages are equal to or greater than the short term absolute minimum voltage of 2.07 V. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.8.6.3 The limit specified for electrolyte level ensures that the plates suffer no physical damage and maintains adequate electron transfer capability.

The minimum design electrolyte level is the minimum level indication mark on the battery cell jar. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.8.6.4 This Surveillance verifies that the pilot cell temperature is greater than or equal to the minimum established design limit (i.e., 40°F). Pilot cell electrolyte temperature is maintained above this temperature to assure the battery can provide the required current and voltage to meet the design requirements. Temperatures lower than assumed in battery sizing calculations act to inhibit or reduce battery capacity. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

SR 3.8.6.6 A battery performance discharge test is a test of constant current capacity of a battery, normally done in the as found condition, after having been in service, to detect any change in the capacity determined by the acceptance test. The test is intended to determine overall battery degradation due to age and usage.

PERRY - UNIT 1 B 3.8-66 Revision No. 11

Battery Cell Parameters B 3.8.6 The battery performance discharge test is acceptable for satisfying SR 3.8.6.6.

The acceptance criteria for this Surveillance are consistent with IEEE-450 (Ref. 1) and IEEE-485 (Ref. 5). These references recommend that the battery be replaced if its capacity is below 80% of the manufacturers rating. A capacity of 80% shows that the battery rate of deterioration is increasing, even if there is ample capacity to meet the load requirements.

Furthermore, the battery is sized to meet the assumed durty cycle loads when the battery design capacity reaches this 80% limit. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

If the battery shows degradation, or if the battery has reached 85% of its expected life and capacity is < 100% of the manufacturers rating, the Surveillance Frequency is reduced to 12 months. However, if the battery shows no degradation but has reached 85% of its expected life, the Surveillance Frequency is only reduced to 24 months for batteries that retain capacity 100% of the manufacturers rating. Degradation is indicated, according to IEEE-450 (Ref. 1), when the battery capacity drops by more than 10% relative to its capacity on the previous performance test or when it is 10% below the manufacturers rating. All these Frequencies are consistent with the recommendations in IEEE-450 (Ref. 1).

This SR is modified by a Note. Credit may be taken for unplanned events that satisfy this SR. This note is provided to prevent unnecessary cycling of plant equipment.

The SR verifies that Category A battery cell parameters are consistent with IEEE-450 (Ref. 3), which recommends regular battery inspections including electrolyte level, float voltage, and specific gravity of pilot cells.

The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

This inspection is also consistent with IEEE-450 (Ref. 3), which recommends special inspections following a severe overcharge, to ensure that no significant degradation of the battery occurs as a consequence of such overcharge.

The Surveillance Frequency is controlled under the Surveillance Frequency Control Program. Ten connected cells shall be sampled during this Surveillance.

Lower than normal temperatures act to inhibit or reduce battery capacity.

This SR ensures that the operating temperatures remain within an acceptable operating range. This limit is based on manufacturers recommendations.

Table 3.8.6-1 This table delineates the limits on electrolyte level, float voltage, and specific gravity for three different categories. The meaning of each category is discussed below.

Category A defines the normal parameter limit for each designated pilot cell in each battery. The cells selected as pilot cells are those whose electrolyte level, float voltage, and specific gravity approximate the state of charge of the entire battery.

The Category A limits specified for electrolyte level are based on manufacturers recommendations and are consistent with the guidance in IEEE-450 (Ref. 3), with the extra 1/4 inch allowance above the maximum level indication mark for operating margin to account for temperature and charge effects. In addition to this allowance, footnote (a) to Table 3.8.6-1 permits the electrolyte level to be above the specified maximum level during equalizing charge, provided (continued)

REQUIREMENTS it is not overflowing. These limits ensure that the plates suffer no physical damage, and that adequate electron transfer capability is maintained in the event of transient conditions. IEEE-450 (Ref. 3) recommends that electrolyte level readings should be made only after the battery has been on a float charge for at least 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months .

The Category A limit specified for float voltage is 2.13 V per cell. This value is based on the recommendation of IEEE-450 (Ref. 3), which states that prolonged operation of cells below 2.13 V can reduce the life expectancy of cells.

The Category A limit specified for specific gravity for each pilot cell is 1.200 for Divisions 1 and 2 and 1.195 for Division 3 (0.015 below the manufacturers fully charged nominal specific gravity). This value is characteristic of a charged cell with adequate capacity. According to IEEE-450 (Ref. 3), the specific gravity readings are based on a temperature of 77°F (25°C).

The specific gravity readings are corrected for actual electrolyte temperature and level. For each 3°F (1.67°C) above 77°F (25°C), 1 point (0.001) is added to the reading; 1 point is subtracted for each 3°F below 77°F. The specific gravity of the electrolyte in a cell increases with a loss of water due to electrolysis or evaporation. Level correction will be in accordance with manufacturers recommendations.

Category B defines the normal parameter limits for each connected cell.

The term connected cell excludes any battery cell that may be jumpered out.

The Category B limits specified for electrolyte level and float voltage are the same as those specified for Category A and have been discussed above. The Category B limit specified for specific gravity for each connected cell is 1.195 for Division 1 and Division 2 and 1.190 for Division 3 (0.020 below the manufacturers fully charged, nominal specific gravity) with the average of all connected cells 1.205 for Divisions 1 and 2 and 1.200 for Division 3 (0.010 below the manufacturers fully charged, nominal specific gravity).

REQUIREMENTS These values are based on manufacturers recommendations. The minimum specific gravity value required for each cell ensures that the effects of a highly charged or newly installed cell do not mask overall degradation of the battery.

Category C defines the limits for each connected cell. These values, although reduced, provide assurance that sufficient capacity exists to perform the intended function and maintain a margin of safety. When any battery parameter is outside the Category C limit, the assurance of sufficient capacity described above no longer exists, and the battery must be declared inoperable.

The Category C limit specified for electrolyte level (above the top of the plates and not overflowing) ensures that the plates suffer no physical damage and maintain adequate electron transfer capability. The Category C limit for float voltage is based on IEEE-450 (Ref. 3), which states that a cell voltage of 2.07 V or below, under float conditions and not caused by elevated temperature of the cell, indicates internal cell problems and may require cell replacement.

The Category C limit of average specific gravity ( 1.195 for Division 1 and Division 2 and 1.190 for Division 3), is based on manufacturers recommendations (0.020 below the manufacturers recommended fully charged, nominal specific gravity). In addition to that limit, it is required that the specific gravity for each connected cell must be no less than 0.020 below the average of all connected cells. This limit ensures that the effect of a highly charged or new cell does not mask overall degradation of the battery.

The footnotes to Table 3.8.6-1 that apply to specific gravity are applicable to Category A, B, and C specific gravity.

Footnote (b) in Table 3.8.6-1 requires the above mentioned correction for electrolyte level and temperature, with the exception that level correction is not required when battery charging current is < 2 amps on float charge.

This current provides, in general, an indication of overall battery condition.

REQUIREMENTS Because of specific gravity gradients that are produced during the recharging process, delays of several days may occur while waiting for the specific gravity to stabilize. A stabilized charger current is an acceptable alternative to specific gravity measurement for determining the state of charge. This phenomenon is discussed in IEEE-450 (Ref. 3).

Footnote (c) to Table 3.8.6-1 allows the float charge current to be used as an alternate to specific gravity for up to 7 days following a battery recharge. Within 7 days each connected cells specific gravity must be measured to confirm the state of charge. Following a minor battery recharge (such as equalizing charge that does not follow a deep discharge) specific gravity gradients are not significant, and confirmatory measurements may be made in less than 7 days.
