Attachment 1 GNRO-2015/00002 RESPONSES TO REQUEST FOR ADDITIONAL INFORMATION DATED 1219/2014 PERTAINING TO LICENSE AMENDMENT REQUEST - REVISION TO BATTERY CELL RESISTANCES TO ADDRESS POTENTIAL NON-CONSERVATIVE TECHNICAL SPECIFICATION to Page 1 of 6 GNRO-2015/00002

1. Existing SRs 3.8.4.2 and 3.8.4.5 require verification of battery connection resistance for inter-cell, inter-tier, inter-rack and terminal connections. The revised SRs 3.8.4.2 and 3.8.4.5 do not include verification of battery terminal connection resistances for all three divisions and inter-rack connection resistances for Division 3 battery.

a. Please provide the acceptance criteria for the terminal connection resistances for Divisions 1, 2, and 3 batteries and for the inter-rack connection resistances for the Division 3 battery. Otherwise, please explain why the licensee is deviating from the current requirements in SRs 3.8.4.2 and 3.8.4.5.

Response to RAI 1.a: The acceptance criteria for the inter-rack connection resistances for the Division 3 battery is not provided because SR 3.8.4.2 and SR 3.8.4.5 contain terminology not in use at GGNS that was inadvertently introduced during the incorporation of the Improved Technical Specifications. "Inter-rack" is not valid at GGNS for Division 3 battery 1C3; only "inter-cell" and "inter-tier" connections are present for the Division 3 1C3 battery. Therefore, removing the "inter-rack" requirement from SRs 3.8.4.2 and 3.8.4.5 for the Division 3 battery 1C3 is appropriate. Individual terminal resistance is not explicitly defined for SR 3.8.4.2 and SR 3.8.4.5 as the terminal resistance is accounted for in the inter-cell resistance value. 125 Volt Battery Bank Physical Condition Check Surveillance 06-EL-1 L11-R-0001 defines the points for which the test values are taken; it has been attached as reference. GGN is deviating from the current requirements inSRs 3.8.4.2 and 3.8.4.5 because terminal resistance is accounted for in the resistance values for inter-cell connections therefore it is appropriate to remove terminal connection resistance values from SR 3.8.4.2 and SR 3.8.4.5. Each battery cell has two terminals, a positive and negative terminal. Batteries 1A3 and 1B3 have cells that are simply connected in series: 1A3 Cell 1 "Neg. Terminal" is connected via two "Inter-cell" connections to 1A3 Cell 2 "Pos. Terminal". 1A3 Cell 1 "Pos. Terminal" is the positive connection of the battery; 1A3 Cell 60 "Neg. Terminal". Figure 1 is the data sheet for the physical condition check for the 1B3 battery. Battery vendor C&D Technologies has specified that the Battery Characteristic Curve accounts for battery cell connection resistances. To develop the proposed SR 3.8.4.2 and SR 3.8.4.5 resistance values, work orders for surveillance 06-EL-1L11-R-0001 were reviewed for the 10 year period 2002 to 2012. Using the recorded surveillance data, an average connection resistance specific to each battery was developed which estimated the baseline resistance described by the respective C&D Battery Curve. Margin was then developed and accounted for as described in each calculation. Adequacy of battery terminal voltage using the resistance values for inter-cell, inter-rack (if applicable), and inter-tier previously established in CR-GGN-2007-00181 CA-00001 are validated by calculations EC-to Page 2 of 6 GNRO-2015/00002 Q1L21-90033 (Division 1), EC-Q1 L21-90046 (Division 2), and EC-Q1 L21-90023 (Division 3) in Engineering Change EC-43968.

Figure 1 Surveillance 06-EL-1 L11-R-0001, "125 Volt Battery Bank Physical Condition Check," has the following step on page 5 for Division 1 and Division 2 batteries 1A3 and 1B3:

1. "For regular Pas. or Neg. intercell Post connection take resistance from Test Point A to Test Point B for each side. Record the Highest reading.

Administrative Limit is 50 Micro-Ohms for each connection" As described by Figure 2, below, two copper bars are used interconnecting the post. Test Point A is on the terminal post while Test Point B is taken on both copper interconnecting bars, but only the highest resistance is recorded. The resulting ohm reading is the "intercell" resistance. Continuing with instructions from surveillance 06-EL-1 L11-R-0001 : to Page 3 of 6 GNRO-2015/00002

2. "For battery end connection and cell 30 to cell 31, take resistance from Test Point C to Test Point 0 Record reading. Administrative Limit is 100 Micro-Ohms for each connection" The above step in the surveillance is for interrack connections and as such the end terminal connection is included in the terminology of interrack.

3. "For battery Pos or Neg end terminal connection take resistance readings from Test Point A to field cable terminal lug. Record readings. Administrative Limit is 100 Micro-Ohms for each connection."

The Division 3 battery's terminal connection resistance is measured in the same manner as Division 1 and Division 2 batteries.

b. In the proposed revised SRs, the word "battery" is deleted from the statements.

For clarification of the proposed acceptance criteria, please consider adding the word "battery" to the statements. Response to RAI 1.b: The word "battery" will be added to the statements for clarification of the proposed acceptance criteria.

2. In Attachment 1 of the LAR, the licensee .steted that Engineering Change (EC) 43968 concluded that the proposed acceptance criteria for battery connection resistances in TS Surveillance Requirements (SRs) 3.8.4.2 and 3.8.4.5 are appropriate for Divisions 1,2, and 3 batteries (1A3, 183, and 1C3). Provide a copy of EC 43968.

Response to RAI 2: A copy of EC-43968 is attached (See Attachment 3).

3. Section 8.3.2.1.6.2 of the GGNS updated safety analysis report states that the voltage at the safety-related battery terminals is designed to be maintained within the limit of 105 volts direct current (VDC) to 140 VDC during all modes of plant operation, including the first 4 hours of accident conditions.

a. Please confirm that the minimum battery required terminal voltage (i.e., 105 V) will be maintained during and at the end of the battery performance/service test, if each battery connection (i.e., inter-cell, inter-tier, inter-rack, and terminal) is at the proposed maximum resistance value and all inter-tier and inter-rack connecting cables resistances are considered.

Response to RAI 3.a: Section 8.3.2.1.6.2 of the GGNS UFSAR discusses batteries 1A3 (Division 1) and 183 (Division 2) stating, "The voltage at the safety-related dc battery terminals is designed to be maintained within the limit of 105 V dc to 140 V dc during all modes of plant operation, including the first 4 hours of accident conditions. The minimum acceptable battery terminal voltages per time interval to support essential component operability are provided in Tables 8.3-6 and 8.3-7." Voltages and duration quoted in the UFSAR in section 8.3.2.1.6.2 are consistent with System Design Criteria SDC-01 section 4.7 (see Enclosure 4). Although the design of batteries 1A3 and 183 have the lower limiting voltage of 105 V dc, the minimum voltage to Page 6 of 6 GNRO-20 15/00002 to support operability of equipment is higher as shown in Tables 8.3-6 and 8.3-7. EC-43968 confirms the resultant battery terminal voltages using the proposed inter-cell, inter-rack, and inter-tier resistances are maintained higher than the minimum values shown in Table 8.3-6 and Table 8.3-7. Service Discharge Testing is performed by Surveillance 06-EL-1 L11-R-0003 (see Attachment 4).

b. Please confirm that the limiting voltage of 105 V provides adequate battery terminal voltage for all loads during the first 4 hours of accident conditions.

Response to RAI 3.b: Yes, the limiting voltage of 105V provides adequate terminal voltage for all loads. The lower limiting voltage of 105 V dc of 1A3 and 183 however is not in reference to the minimum battery terminal voltage. Please see Tables 8.3-6 and 8.3-7 (see Attachment 5) for the minimum battery terminal voltages for emergency loads per time interval after AC power loss.

EXTRACTED FROM SECTION 5.7 ENGINEERING EVALUATION EC No.: 43968 REV. No.: 0 SHEET 1 OF 8 1.0 Description 1.1 Structure. System. or Component Description (basic functions. critical characteristics and performance requirements) The Division I and Division II 125 Vdc Distribution Systems supplies power to the Division I and II 125 Vdc Class 1E loads. The Division III 125 Vdc Distribution System supplies power to the HPCS 125 Vdc Class 1E loads. 1.2 Reason for Change (include background information as necessary) CR-GGN-2007-00181 determined that GGNS 125 Vdc Class 1E Voltage Drop calculations did not properly account for battery cell connection resistances. CR~GGN-2011-08867 identified that there were potential conflicts between the impacts issued against Division I 125 Vdc Class 1E Voltage Drop calculation EC-Q1 L21-90033. 1.3 Design Objective to Resolve Problem Issue EC Markups to properly account for battery cell connection resistances in the Division I, Division II and Division III 125 Vdc Class 1E Voltage Drop calculations listed in Section 2.1. Since the incorporation of battery cell connection resistances has the potential to affect all downstream voltages, any markups that are pending incorporation should be included in the voltage drop spreadsheets to ensure accuracy. Additionally, the markup against the Division I 125 Vdc Class 1E Voltage Drop calculation will incorporate markups that are pending to eliminate potential conflicts between the impacts to this calculation. 2.0 Documents 2.1 Affected Documents List (ADL) 2.1.1 EC-Q1 L21-90033 2.1.2 EC-Q1 L21-90046 2.1.3 EC-Q1 L21-90023 EN-De-115, Rev. 14

EXTRACTED FROM SECTION 5.7 ENGINEERING EVALUATION EC No.: 43968 REV. No.: 0 SHEET 3 OF 8 3.0 Evaluation and Design Summary 3.1 Evaluation Resolution (include appropriate justification) EC43968 provides markups for 125 Vdc Class 1E Voltage Drop Calculations EC-Q1 L21-90023, EC-Q1L21-90033, and EC-Q1 L21-90046. The calculation markups are designed to properly account for battery cell connection resistances associated with Division I, Division II and Division III 125 Vdc Class 1E batteries and distribution system. The markup for each calculation provides a very detailed discussion of the methodology employed and the resulting cell connection resistances. The methodology is conservative and is *consistent with recommendations provided by the vendor (C&D) regarding battery cell connection resistances. Because the incorporation of battery cell connection resistances has the potential to affect downstream voltages, the existing markups that are pending incorporation have been included in the voltage drop spreadsheets to ensure accuracy of the voltage results. Additionally, incorporation of the pending markups into the Division I 125 Vdc Class 1E Voltage Drop calculation spreadsheet eliminates conflicts that have evolved between the markups to this calculation. There were no significant impacts to the conclusions for Division I calculation EC-Q1 L21-90033, Division II calculation EC-Q1L21-90046 or Division III calculation EC-Q1 L21-90023. It is important to note that the EC43968 calculation markups do not represent a change to the facility, but document the existing configuration that is in place considering pending calculation markups that are ready to be implemented and the existing battery cell connection resistances. 3.2 Design Bases Discussion (include related Codes and Standards) See Section 1.1 3.3 Design Input Considerations (Not required when a Design Input Record, per EN-DC-.141, is attached) Design Input considerations are provided below in accordance with EN-DC-141 Section 5.3[1].

No.: 0 SHEET 4 OF 8 3.3.1 Performance Requirements / Electrical Requirements Each Division I and Division II battery shall be sized to supply the required loads for 4 hours. The Division III battery shall be sized to supply the required loads for 2 hours. In order to meet this requirement, the voltage drop calculations must ensure that adequate voltage is received at all required devices. Reference SDC-01, SDC-10 and EC-Q1 L21-90020 3.3.2 Consider the impact of other modifications (EC) initiated against the same system/by consulting the site design databases. In order to ensure accuracy of the results and to resolve some identified conflicts, Asset Suite will be reviewed to determine the outstanding markups that are pending incorporation. The markups that are pending will be incorporated into the calculation spreadsheets to eliminate potential conflicts. 3.3.3 Consider the effect on other components. The process of completing the calculation markups includes review to ensure that required devices which do not receive adequate voltage are addressed. 3.3.4 Licensing Basis, including review for impact on Tech Specs The EC PAD/Screening process will ensure that any Licensing Basis impacts are identified. It is known that UFSAR Tables 8.3-6,8.3-7 and 8.3-8 must be reviewed for impact. Additionally, actions from CR-GGN-2007-00181 (see CR-GGN-2011-00036 CA489) are being tracked to address non-conservative Technical Specification battery inter-cell resistance requirements. Reference UFSAR Tables 8.3-6, 8.3-7 and 8.3-8, CR-GGN-2007-00181 3.3.5 Vendor Interface The amount of resistance that should be added to the calculations to account for battery cell connections is coordinated with the battery vendor (C&D).

GGNS initiated CR-GGN-2007-00181 for this condition and implemented administrative controls for more conservative battery cell connection resistance until the non conservative Tech Spec is resolved. EC43968 is implementing these conservative battery cell connection resistances into the respective battery voltage drop calculations. Actions from CR-GGN-2007-00181 (CR-GGN-2011-00036 CA489) are being tracked to address non-conservative Technical Specification battery inter-cell resistance requirements. 3.6.2 OE25319 OE25319 (Sequoyah) identified during Sequoyah's CDBI inspection, documents that the maximum allowable connection resistance (150 micro-ohm from Technical Specification 3/4.8.1.1.3 and 3/4.8.2.3.2) for each of the emergency diesel and vital battery connections was not accounted for in voltage calculations.

                   , This issue is being address by on-going actions resulting from CR-GGN-2007-00181, including EC43968.

EXTRACTED FROM SECTION 5.7 ENGINEERING EVALUATION EC No.: 43968 REV. No.: 0 SHEET 7 OF 8 3.7 Margin Analysi~ The GGNS Margin Issues Database was reviewed and no hits were found related to the L21 or E22 batteries or distribution systems. However, there appears to be a margin concern with the Class 1E125 Vdc Voltage Drop Calculations. This concern does not necessarily translate to an equipment margin concern due to the very conservative nature of the calculations. The calculation margin concern is evidenced by conditions identified in MNCR 0251-90, MNCR 0277-90 and CR-GGN-2012-08172 and the very small amount of voltage margin displayed in EC-Q1L21-90033, EC-Q1L21-90046, and EC-Q1 L21-90023. This potential margin concern has been communicated to the Margin Issues Database Coordinator for tracking. 4.0 Impact on Current Operational Basis (describe potential operational impact). NOTE ny required instructions for switching between alternate configurations should be provided in separate design output documents or a cross reference to the En ineerin Chan e should be rovided. 4.1 There is no impact on the current operational basis. 5.0 Engineering Requirements Necessary to Implement the Change (include potential conflicts, sequencing problems, precautionary statements, Engineered Safety Features actuations, and partial installations) 5.1 There are no changes to be physically implemented.

ESF 125-Volt Battery Bank Service Discharge Test 06-EL-1L11-R-0003 Revision: 108 Page: 1 (Load Profile) 1.0 PURPOSE 1.1 To service test the 125 VDC batteries to ensure operability. This procedure is applicable to Batteries 1A3, 1B3, and 1C3. 1.2 A battery service test is required at least once every 18 months in accordance with SR 3.8.4.7 of the GGNS Technical Specifications (SR 3.8.5.1 does not require test performance to maintain operability). Battery load profiles are given in UFSAR Tables 8.3-6, 8.3-7 and 8.3-8. 1.3 The battery test discharge rates listed in Attachments I and II are conservative administrative rates and are approximately 20 amps higher for Division I and II than listed in UFSAR Tables 8.3-6 (Div I), and 8.3-7 (Div II). The battery test discharge rates listed in Attachments III are conservative administrative rates and are 5 amps higher for Division III than listed in UFSAR Tables 8.3-8 (Div III). If the battery fails to meet the administrative discharge rate, the test may be re-performed using the rates listed in USFAR to maintain operability. This additional test amperage allows for some additional load gains without requiring additional testing. 1.4 Changes required for implementation of 1994 TSIP were incorporated in Revision 100. For historical reference this statement should not be deleted. 2.0 PRECAUTIONS AND LIMITATIONS 2.1 Steps marked with a pound sign (#) are to be initialed on the data sheet or data entered as each step is completed. Optional steps are marked N/A and any steps repeated must be re-initialed. 2.2 Steps marked with a dollar sign ($) are required to be completed for Technical Specifications Acceptance Criteria. 2.3 If "As Found" values are not in tolerance, if procedural steps cannot be completed as. stated, or if any other problem develops during this test, notify immediate supervisor and the Shift Supervisor. 2.4 If "As Found" values exceed Technical Specifications tolerance, notify Shift Supervisor. 2.5 Wear protective equipment as required by GGNS safety procedures when handling, checking, filling, charging, or repairing batteries. 2.6 Battery room hydrogen concentration shall not exceed 2% hydrogen by volume as indicated on portable Combustible Gas Monitor or installed detector. 2.7 While performing the battery service discharge test, if an individual cell is approaching reversal of its polarity (plus 1.0 volt or less), but the battery terminal voltage has not yet reached its lower test limit, the test should be temporarily discontinued, the battery disconnected from the load, and the weak cell removed from the battery. 2.8 Smoking, or any kind of fire, will not be allowed in the battery room. 2.9 Do not perform discharge test if average cell temperature exceeds 90°F prior to test. 2.10 Battery connections removed during the test should be torqued and resistance measured when reconnected per 06-EL-1L11-R-0001.

ESF 125-Volt Battery Bank Service Discharge Test 06-EL-1L11-R-0003 Revision: 108 Page: 2 (Load Profile) 2.11 Personnel performing this procedu~e should be familiar with Section Procedure 07-S-02-2, Special Guidance for the Performance of Electrical Activities and EN-IS-123, Electrical Safety. 2.12 The battery amperage loading shall be maintained within -0%, and should be within + 2% by manual control, if required. 2.13 Data calculations in this procedure may be performed at any time after the appropriate data has been collected and recorded. 2.14 Battery charger failures can occur when the Div I or II DC bus are being svpplied solely from the chargers, that result in voltage perturbations which inverters 1Y87 and 1Y96 (lY88 and 1Y95) are not designed to accommodate. The, inverters are placed on their more reliable alternate AC sources during this test. 2.15 Isolation of RHR Shutdown Cooling can result from DC bus voltage perturbations or loss of AC power on the division under test during performance of at'tachments I and II. To prevent loss of Shutdown Cooling, the E12F008 or E12F009 valve breaker for the valve powered from the division under test is opened and the cross divisional high RPV pressure isolation logic may be defeated. Technical Specification 3.6.1.3 requires one of the Shutdown Cooling suction isolation valves to be operable when the common suction is in service. The Shift Supervisor may N/A this step if Shutdown Cooling or ADHR is not required to be operable through common suction line. 3.0 REOUIRED MATERIAL AND TEST EQUIPMENT 3.1 Attachment I-III (as required by battery to be tested) 3.2 DVM, 2 required, Fluke 45 or equivalent 3.3 Ammeter or shunt of suitable range for test if States Load Box is used (100 AMP) (Attachment III only) 3.4 Combustible Gas Detector MSA 100 or equivalent, or installed operable detector 3.5 Hydrometer, analog or digital (e.g., C&D PL-538, PL-636), or equivalent 3.6 Load Bank equipment, States Load Box or Battery Capacity Tester as required 3.7 Thermometer, glass, 0-160 oF or equivalent, as required 3.8 Stopwatch with accuracy of at least 0.5 second and range of 60 minutes 3.9 Ammeter, DC, Clamp-On 3.10 Torque wrench 0-150 in-lbs or equivalent -' 3.11 Protective equipment as required per EN-rS-111, Industrial Safety Requirements to include eyewash station, and Bicarbonate of Soda 3.12 Ruler, non-conductive (without metal edge) 3.13 Insulated tools, when working on or near exposed electrical equipment 3.14 Barriers, as required to eliminate electrical/physical hazards J:\ADM_SRVS\TECH_PUB\REVISION\06\EL\06-EL-1L11-R-0003.DOC

The Division I Class 1E DC Electrical Power Subsystem must meet LCO 3.8.5.a to perform this test. (The division I battery must be connected) 1.3 The E12F009 breaker may be open and both division high RPV pressure isolation logics may be defeated for this test to preclude possible spurious shutdown cooling suction isolation which can result from Div II DC bus voltage fluctuations while the battery is disconnected from the bus. If shutdown cooling or ADHR is not required to be operable *through common suction line, the Shift Supervisor may N/A this step. 1.4 Inverters 1Y88 and 1Y95 are placed on ALTERNATE SOURCE TO LOAD to reduce the risk of inverter loss during this test. 1.5 A loss of bus 16AB during this test will also result in loss of Div II DC and inverter 1Y88 and 1Y95 power which will result in a Div I half isolation signal to the Shutdown Cooling Isolation logic. 2.0 PROCEDURE 2.1 Plant Mode is (circle one): 4 5 2.2 Test start time / date: / / Performer / Time / Date 3.0 TEST RESULTS 3.1 Test Completion: (Check one in each category.)

Attachment 5 GNRO-2015/00002 GGNS UFSAR TABLES 8.3-6 AND 8.3-7, MINIMUM ACCEPTABLE BATTERY TERMINAL VOLTAGES

GG UFSAR Class IE equipment in accordance with applicable clauses of IEEE 308. They are designed so that no single failure in any 125 volt dc system will result in conditions that prevent safe shutdown of the plant. The plant design and circuit layout from these dc systems provide physical separation of the equipment, cabling, and instrumentation essential to plant safety. Each 125 volt dc battery is separately housed in a ventilated room apart from its charger and distribution center. Each system is located in an area separated physically from other systems. All components of the Class IE 125 volt dc systems are housed in seismic Category I structures. The safety-related battery chargers are of sufficient capacity to operate all non-accident shutdown loads, assuming the battery is not available. It should, however, be noted that the Division I and II battery chargers are suitable for use with or without the battery physically connected. The Division III battery charger is designed for*use with or without the battery physically connected. When operated as stated above, the Division I, II, and III battery chargers will maintain a stable output for all ranges of load. 8.3.2.1.6.1 125 Volt DC Systems Identification Figure 8.3-10 shows the Class IE 125 volt dc systems. Battery lA3 feeds into a direct-current distribution center designated as 11DA. Two battery chargers 1A4 and lAS, are fed from the 480 volt engineered safety features load center ,buses, 15BA3 and lSBA6, which are supplied by a diesel generator if the offsite power source is unavailable. The 125 volt dc system A is formed at the bus of distribution center 11DA, and the power is fed into distribution panels to serve various loads. System B is similar to system A, with the distribution center designated as 11DB, the battery as 1B3, battery chargers as 1B4 and 1B5, and 480 volt load centers as 16BB3 and 168B6. The 125 volt dc system C identification is described in subsection 8.3.2.1.7.4. 8.3.2.1.6.2 Battery Capacity Considerations Batteries 1AJ and 1B3 have sufficient stored energy to operate connected essential loads continuously for at least 4 hours and to perform three complete cycles of intermittent loads. Tables 8.3-6 and 8.3-7 give loads to be supplied from the 125 volt dc systems during accident conditions. Each distribution circuit is capable of transmitting sufficient energy to start and operate all required loads in that circuit. Batteries 1A3 and 183 are sized in accordance with IEEE 485-1978. 8.3-62 LDe 96038

GG UFSAR "- The voltage at the safety-related dc battery terminals is designed to be maintained within the limit of 105 V dc to 140 V dc during all modes of plant operation, including the first 4 hours of accident conditions. The minimum acceptable battery terminal voltages per time interval to support essential component operability are provided in Tables 8.3-6 and 8.3-7. _1 ~ ..' 8.3-62a Rev. 8 5/94

GG UPSAR All direct current equipment for Grand Gulf has been specified for operation over the range of 105 V dc to 140 V de. Components whose qualifications can not meet this specified range are evaluated on a case by case basis. These values correspond respectively to the minimum design discharge voltage and the normal float voltage (plus margin) for the batteries. Due to voltage drop between the battery terminal and the individual components, actual voltages at the individual components will be below the battery terminal voltage. Unless qualified by field testing, all essential components. will be qualified by the manufacturer for the calculated limiting voltage supplied to the equipment. It should be noted that the lead calcium type of batteries utilized on Grand Gulf are designed to be operated at a nominal float voltage of between 132 and 135 V dc without requiring a periodic equalizing charge. Equalizing charges are performed if an inspection or test finds the battery cell voltage or specific gravity readings are below that as indicated in the Technical Specifications as a minimum. Equalizing charges are performed after battery service discharge test and battery performance discharge test. 8.3.2.1.6.3 Ventilation Battery rooms are ventilated to remove the gases produced due to the charging of batteries. The ventilation system for the Class IE batteries is Class IE and redundant. 8.3.2.1.6.4 Maintenance and Testing All components of the 125 volt dc systems undergo periodic maintenance tests to dete~ine the condition of each individual subsystem. Batteries are checked for electrolyte level, specific gravity and cell float VOltage, and visually inspected following manufacturer's recommended procedures. The service test minimum load profiles and minimum acceptable battery terminal voltages for the A and B dc system batteries are contained in Tables 8.3-6 and 8.3-7. A performance discharge test will be given regularly to demonstrate the Class IE batteries have sufficient stored energy to supply the load demand discussed in section 8.3.2.1.6.2. Battery chargers are periodically checked by visual inspection and performance tests. Testing is performed in accordance with the Technical Specifi-cations, and will include requirements for measurement of cell-to-cell as well as terminal connection resistance. 8.3-63 Rev. 8 5/94
