APPLICABILITY BASES i
3.0.5 This specification delineates what additional conditions must be j
satisfied to permit operation to continue, consistent with the ACTION statements for power sources, when a normal or emergency power source is not' OPERABLE.
It specifically prohibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in another division is inoperable for another reason.
The provisions of this specification permit the ACTION statements associated with individual systems, subsystems, trains, components, or devices to be consistent with the ACTION statements of the associated electrical power source.
It allows operation to be governed by the time limits of the ACTION statement associated with the Limiting Condition for Operation' for the normal i.
or emergency power source, not the individual ACTION statements for each system, subsystem, train, component or device that is determined to be inoper-l able solely because of the inoperability of its normal or emergency power j
source.
l For example, Specification 3.8.1.1 requires in part that two emergency diesel i
generators be OPERABLE. The ACTION statement rrovides for a 72-hour out-of-service time when one emergency diesel generator is not OPERABLE.
If the i
definition of OPERABLE were applied without consideration of Specification l
3.0.5, all systems, subsystems, trains, components and devices supplied by the i
inoperable emergency power source would also be inoperable. This would dictate j
invoking the applicable ACTION statements for each of the applicable Limiting Conditions for Operation. However, the provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the i
ACTION statement for the inoperable emergency diesel generator instead, provided the other specified conditions are satisfied.
In this case, this would mean i
that the corresponding normal power source must be OPERABLE, and all redundant systems, subsystems, trains, components, and devices must be OPERABLE, or otherwise satisfy Specification 3.0.5 (i.e., be capable of performing their design function and have at least one normal or one emergency power source 4
OPERABLE).
If they are not satisfied, action is required in accordance with i
this specification.
j As a further example, Specification 3.8.1.1 requires in part that two qualified l
1 circuits between the offsite transmission network and the onsite Class IE distribution system be OPERABLE. The ACTION statement provides a 24-hour out-of-service time when both required qualified circuits are not OPERABLE.
l
}
If the definition of OPERABLE were applied without consideration of Specification 3.0.5; all systems, subsystems, trains, components and devices supplied by the inoperable normal power sources, both of the qualified l
circuits, would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the applicable LCOs.
However, the provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTION statement 4
for the inoperable normal power sources instead, provided the l

i BASES i
i l
The OPERABILITY of the A.C. and D.C. power sources and associated distribu-tion Systems during operation ensures that sufficient power will be available to supply the safety related equipment required for 1) the safe shutdown of the facility and 2) the mitigation and control of accident i
conditions within the facility. The minimum specified independent and i
redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General design Criterion 17 of Appendix "A" to 10 CFR 50.
l Qualified offsite to onsite circuits are those that are described in the USAR and are~ part of the licensing basis for the plant.
An OPERABLE' qualified offsite to onsite circuit consists of all breakers, i
transformers, switches, interrupting devices, cabling, and controls required
.to transmit power from the offsite transmission network to the onsite Class IE i
essential buses.
An OPERABLE qualified offsite to onsite circuit consists of:
1.
One OPERABLE 345 kV transmission line 2.
One OPERABLE 345 - 13.8 kV startup transformer 3.
One OPERABLE 13.8 kV bus, and 4.
One OPERABLE 13.8 - 4.16 kV bus tie transformer.
Typically, the electrical power reserve source selector switches are selected to the two different startup transformers. However, under certain conditions it is appropriate to select both switches to the same startup transformer.
The circuit in which the startup transformer does not have a reserve source selector switch pre-selected to it must still meet the requirements of having its 345 kV transmission line, startup transformer,13.8 kV bus _and bus tie transformer OPERABLE.
In the case where a 13.8 kV bus is powered from a startup transformer, the reserve source selector switch should be selected to the opposite startup j
transformer.-
In MODES 1-4, if one of the required 13.8 kV - 4.16 kV bus tie transformers is inoperable, then one qualified offsite to onsite circuit is inoperable and the requirement of LCO 3.b.1.1.a is not met. The appropriate corresponding ACTION statement must be entered. The essential 4.16 kV buses remain OPERABLE while energized with one 13.8 kV - 4.16 kV bus tie transformer inoperable, j
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power i
sources are consistent with the initial condition assumptions of the safety analyses and are based upon maintaining at least one of each of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of the other onsite A.C. source.

Surveillance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.c.4 verify proper starting of the Emergency Diesel Generators from standby conditions.
4 Verification that an Emergency Diesel Generator has achieved a frequency i
of 60 Hz within the required time constraints meets the requirement for
+
verifying the Emergency Diesel Generator has accelerated to 900 RPM.
i The OPERABILITY of the minimum specified A.C. and D.C. power sources and j
associated distribution systems during shutdown and refueling ensures that
- 1) the facility can be maintained in the shutdown or refueling condition j
for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.
3 I
The Surveillance Requirements for demonstrating the OPERABILITY of the j
station batteries are based on the recommendations of Regulatory Guide 1.129, i
" Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants" February 1978, and IEEE Std. 450-1980, "IEEE j
Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations".
i 1
l Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connec-i tion resistance values and the performance of battery service and discharge j
tests ensures the effectiveness of the charging system, the ability to
(
handle high discharge rates and compares the battery capacity at that time
{
with the rated capacity.
t l
Table 4.8-1 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage and specific gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2.13 volts and.015 below the manufacturer's 8
j full charge specific gravity or a battery charger current of less than two j
amps is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not more than.020 below the manufacturer's fuil charge specific gravity with an average specific gravity of all the connected cells not more than.010 below the manufacturer's full charge specific gravity, ensures the OPERABILITY and capability of the battery. Exceptions I
to the specific gravity requirements are taken to allow for the normal l
deviations experienced after a battery discharge and subsequent recharge associated with a service or performance discharge test. The specific j
gravity deviations are recognized and discussed in IEEE 450-1980.
