transformers. i each Keowee unit has a generation capacity of 87.5 MVA and the main step up transformer is rated for 230 MVA. this power capacity exceeds the Oconee emergency power requirements. In addition to supplying emergency power for Oconee, the Keowee Hydro-units provide peaking power to the Duke Power generation system. During periods of commercial power generation, the Keowee Hydro.units
.are operated within the acceptable region of the Keowee Hydro operating restrictions. This will ensure that the Keowee Hydro units will be able to perform their emergency power functions from an initial condition of commercial power generation. The Keowee Hydro operating restrictions for commercial power generation are contained in the Selected Licensee Commitment manual. Changes to these operating restrictions would be performed in accordance with 10 CFR 50.59, which would include an evaluation to determine if any unreviewed safety questions exist.
Emergency Power Switching Logic Circuits The Emergency Pbwer Switching Logic (EPSL) in conjunction with its associated circuits, is designed with sufficient redundancy to assure that power is.supplied to the unit Main Feeder Buses and, hence, to the unit's essential loads, under accident conditions. The logic system monitors the normal and emergency power sources and, upon loss of the normal power source (the unit aux-iliary transformer), the logic-will seek an alternate source of power.
Operation of the unit with certain circuits or channels of the EPSL inoperable for test or maintenance is permitted for periods of up to 24.hours, provided that the inoperable circuits/channels are in only one portion, or functional unit, of the EPSL and provided that a sufficient number of circuits/channels in the affected functional unit remain operable such that the functional unit does not lose its ability to perform.its designed safety function. These provisions ensure that only one portion of the EPSL is degraded.at a time for test or maintenance on the EPSL and that the affected portion remains operable although degraded.
Emergency power system components (transformers, buses, Keowee Hydro Units, etc.)
which become inoperable for testing or maintenance cause their associated.
circuitry (functional units) of the EPSL to become ineffective. Therefore, the operability of these associated functional units is irrelevant and not required.
In these cases the controlling Technical Specification for the LCO will be the one associated with the inoperability of the emergency power system component(s).
However, all other functional units unaffected by the inoperability of the emergency power system component(s) must meet the requirements of Table 3.7-1 to ensure the operability of the remaining emergency power system.
In the event a 125 VDC instrumentation and control power panelboard becomes inoperable (for planned or unplanned reasons) as allowed by Technical Speci fication 3.7.2(e) (4), circuits or channels of more than one functional unit of EPSL may become inoperable. In this case, continued operation is allowed under the LCO of T.S. 3.7.2(e) (4), provided that no functional units' circuits, etc.,
-addressed by Table 3.7.1 are out of service, which would not have been out of service due to inoperability of the panelboard. This assures that no functional unit of Table 3.7.1 is degraded beyond the requirements for degraded operation, and that the EPSL is capable of performing its intended functiQn.

Annually verify that:
(1) The cells, end-cell plates and battery racks show no visual indication of structural damage or degradation.
(2) The cell to cell and terminal connections are clean, tight and coated with anti-corrosion grease.
4.6.10 Annually, a one hour discharge service test at the required maximum load shall be made on the instrument and control batteries, the Keowee batteries, and the switching station batteries.
4.6.11 Monthly, the operability of the individual diode monitors in the Instrument and Control Power System shall be verified by imposing a simulated diode failure signal on the monitor.
4.6.12 Semiannually, the peak inverse voltage capability of each auctioneering diode in the 125 VDC Instrument and Control Power System shall be measured and recorded.
4.6.13 At least once every 18 months, the ability of the Keowee Hydro units to supply emergency power from an initial condition of commercial power generation shall be verified.
4.6.14 At least once every 18 months, the Keowee Hydro units load rejection response will be verified to be bounded by the design criteria used to develop the Keowee operating restrictions.
Bases The Keowee Hydro units, in addition to serving as the emergency power sources for the Oconee Nuclear Station, are power generating sources for the Duke system requirements. As power generating units, they are operated frequently, normally on a daily basis at loads equal to or greater than required by Table 8.1-1 of.the FSAR for ESF bus loads. Normal as well as emergency startup and operation of these units will be from the Oconee Unit OCONEE - UNITS 1, 2 & 3 4.6-3 Amendment No. 222 (Unit 1 Amendment No. 222 (Unit 2 Amendment No. 219 (Unit 3
1 and 2 Control Room. The frequent starting and loading of these units to meet Duke system power requirements assures the continuous availability for emergency power for the Oconee auxiliaries and engineered safety features equipment.
It will be verified that these units will carry the equipment of the maximum safeguards load within 25 seconds, including instrumentation lag, after a simulated requirement for engineered safety features. To further assure the reliability of these units as emergency power sources, they will be, as specified, tested for automatic start on a monthly basis from the Oconee control room. These tests will include verification that each unit can be synchronized to the 230 kV bus and that each unit can energize the 13.8 kV underground feeder. Also, the verification of the ability of the Keowee Unit ACBs to automatically close to the underground power path will be performed by the annual tests.
In order to ensure that the Keowee Hydro units are operable during periods of commercial power generation, the protection circuitry will be tested at least once every 18 months. This surveillance will ensure that the adverse effects of overspeed following a load rejection will be precluded and the appropriate emergency power paths will be aligned. In addition, the speed sensing governor failure logic will be verified during this surveillance.
Failure to meet the acceptance criteria will be evaluated in the corrective action program to determine the impact on the operability of the emergency power paths. The Keowee Watt/Var meter, frequency relays, and governor magnetic speed switch will be calibrated prior to the performance of this surveillance.
A maximum power dual unit load rejection will be performed at least once every 18 months.* This surveillance will verify that the Keowee Hydro units response to a load rejection is bounded by the design criteria used to develop the Keowee operating restrictions. The design criteria are defined in the calculation that determines the Keowee operating restrictions. A power level for the dual unit load rejection will be defined based on the operating conditions for the day of the test.
In addition, a revision of the operating restrictions for simultaneous operation of both Keowee units will require that a maximum power dual unit load rejection test be performed prior to implementing the revision. A revision of the operating restrictions for a single Keowee unit will require only a maximum power single unit load rejection as defined by the conditions for the day of the test.
However, if a load rejection test is performed to support a revision to the operating restrictions, then no additional load rejection test will be required until the next surveillance. The Keowee Watt/Var meter and frequency relays will be calibrated prior to the performance of this surveillance.

The interval specified for testing of transfer to emergency power sources is based on maintaining.maximum availability of redundant power sources.
Starting a Lee Station gas turbine, separation of the 100 kV line from the remainder of the system, and charging of the 4160 volt main feeder buses are specified to assure the continuity and operability.of this equipment. The one hour time limit is considered the absolute maximum time limit that would be required to accomplish this.
