GRAND GULF NUCLEAR STATION SURVEILLANCE PROCEDURE Title: 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requiring additional testing.1.4 Changes required for implementation of 1994 TSIP were incorporated in Revision 100.For historical reference this statement should not be deleted.2.0 PRECAUTIONS AND LIMITATIONS 2.1 Steps marked with a pound sign (#)are to be initialed on the data sheet or data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.

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.The125 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 "-_1..'GG UFSAR The voltage at the safety-related dc battery terminals is designed to be maintained within the limit of105V 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 8.3-7.8.3-62a Rev.8 5/94 "-GG UPSAR All direct current equipment for Grand Gulf has been specified for operation over the range of105Vdc to140V de.Components whose qualifications can not meet this specified range are evaluatedona 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 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.
