Safe shutdown of the plant, and (2) the mitigation and control of accident conditions within the plant.
When the RCS is above cold
- shutdown, both emergency diesel generators are required to be operable.
The two diesel generators have sufficient capacity to start and run all the engineered safeguards equipment at design loads.
The safeguards equipment operated from one diesel generator can adequately cool the core and maintain the containment pressure within the design value for any loss of coolant incident.
The minimum diesel fuel oil inventory maintained to assure that both diesels can operate at their design ratings for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
This assures that both diesels can carry the design loads of required engineered safeguards equipment for any loss of coolant accident conditions for at least 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />, or for one engineered safety feature train for 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br />.
'~'ommercial oil supplies and trucking facilities exist to assure deliveries within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
The offsite power source consists of separate dedi'cated 34.5 kv-4160 volt station service transformers served by dedicated 34.5 kv lines (12A transformer with dedicated circuit 751, or 12B trans-former with dedicated circuit 767) in operable status.
Either offsite source of power can supply all auxiliary loads and transfer can be accomplished within the time constraints of GDC 17.
- Thus, GDC 17 is explicitly met.
With fuel in the reactor vessel a minimum of one offsite source, one onsite source of AC power and one DC power train are required.
The offsite power source may be provided by one of three configura-tions:
Amendment No. 5]
3.7-5
2.
3.
Transformer 12A served by a dedicated 34.5 kv line (circuit 751), or Transformer 12B served by a dedicated 34.5 kv line (circuit 767), or Backfeed through unit auxiliary transformer 11.
The offsite power source is the preferred source of AC power.
Operability of an offsite source requires that one station service transformer served by a dedicated 34.5 kv line is operating and providing power to the unit.
The emergency diesel generator provides power upon loss of the offsite source.
One emergency diesel generator with 5,000 gallons of fuel can provide power to a minimum level of engineered safeguards equipment for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> (the required safeguards loads at cold shutdown/refueling are signifi-cantly less than during power operation).
One operable diesel fuel oil transfer pump is required to supply fuel from one of the two fuel storage tanks to the day tank of the operable diesel genera-tor.
With less than one offsite AC power source, and one onsite AC power source, one DC power train, and one battery backed instrument bus available, no operations involving positive reactivity changes, core alterations, and movement of irradiated fuel shall occur.
Battery chargers with at least 150 amps capacity shall be in service for each battery so that the batteries will always be at full charge.
This ensures that adequate dc power will be avail-able.
The plant can be safely shutdown without the use of offsite power since all vital loads (safety
- systems, instruments, etc.)
can be supplied from the emergency diesel generators and the station batteries.
Instrument Buses 1A, 1B, and 1C provide power to vital plant instrumentation.
All three buses are backed up by safety related emergency supplies; bus 1A from battery 1A, bus 1C from battery 1B, and bus 1B from diesel generator 1A.
Amendment No.

4.6.4 Instrument Buses Each safety related instrument bus required to be
1.
Verifying nominal voltage indications on the In-strument Buses 1A, 1B, 1C.
2.
Verifying proper supply breaker alignment for Instrument Buses 1A, 1B, and 1C.

Verifying proper static switch alignment for In-strument Buses 1A and 1C.

'he tests specified are designed to demonstrate that the diesel generators willprovide power for operation of equipment.
They also assure that the emergency generator system controls and the control systems for the safeguards equipment willfunction automatically in the event of a loss of all normal 480V AC station service power.
C3.)
The testing frequency specified will be often enough to identify and correct any mechanical or electrical deficiency before it can result in a system failure. The fuel supply and starting circuits and controls are continuously monitored and any faults are indicated by alarm.
An abnormal condition in these systems can be identified without having to test the diesel generators.
Periodic tests are also specified to demonstrate that the offsite power sources will provide power for operation of equipment.
Offsite power source operability requires correct breaker alignment and indicated power availability from the two preferred power
- circuits, 767 and 751, to the 4160 volt buses.
These requirements are met by monitoring nominal voltage indications on the high-voltage side of transformers 12A and 12B; and on the 4160 volt buses 12A and 12B.
Offsite power source independence requires separate 4160 volt circuits supplying power to the 4160 volt buses.
Interlocks prevent concurrent closure of 12AX and 12BX, OR 12AY and 12BY; and surveillance is specified to ensure separation is maintained.
Instrument bus power source operability requires correct breaker alignment and indicated power availability.
These requirements are met by monitoring nominal voltage indications on the buses and proper breaker alignment.
Amendment No.

Furthermore, to assure independence between redundant Class 1E 480 volt buses 14 and 18 (Train A) and buses 16 and 17 (Train B), tie breakers 52/BT16-14 and 52/BT17-18 are required to be open when the plant mode is above 200'F.
Once tie breakers are open, interlocks prevent closure when independent and redundant buses are energized.
Station batteries may deteriorate with time, but precipitous failure is extremely unlikely.
The surveillance specified is that which has been demonstrated over the years to provide an indication of a cell becoming unserviceable long before it fails, and to ensure that the battery capacity is acceptable.
The equalizing charge, as recommended by the manufacturer, is vital to maintaining the ampere-hour capability of the battery.
As a
check upon the effectiveness of the equalizing charge, the battery should be loaded rather heavily and the voltage monitored as a
function of time. If a cell has deteriorated or if a connection is
- loose, the voltage under load will drop excessively indicating replacement or maintenance.
The minimum permissible on-site fuel inventory, 10,000 gallons, (5,000 gallons for each generator),
is sufficient for operation under loss-of-coolant accident conditions of two engineered safety features trains for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />, or for one train for 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br />, or for operation of both diesel generators at their design ratings for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
