t AC Sources - Operating B 3.8.1 BASES ACTIONS A.3 (continued)
The second Completion Time for Required Action A.3 establishes a limiton the maximum time allowed for any combination of.required AC power sources to be inoperable during any single contiguous occurrence of failing to meet the LCO. IfCondition A is entered while, for instance, a DG is inoperable, and that DG is subsequently returned OPERABLE, the LCO may already have been not met for more than 7 days.
This situation could lead to a total of 21 days, since initial failure to meet the LCO, to restore the offsite circuit. At this time, a DG could again become inoperable, the circuit restored OPERABLE, and an additional time period allowed prior to complete restoration of the LCO. The 14 day Completion Time provides a limit on the time allowed in a specified condition after discovery of failure to meet the LCO. This limit is'onsidered reasonable for situations in which Conditions A and B are entered concurrently. The "AND"connector between the 7 day and 14 day Completion Times means that both Completion Times apply simultaneously, and the more restrictive Completion Time must be met.
As in Required Action A.2, the Completion Time allows for an exception to the normal "time zero" for beginning the allowed outage time "clock." This exception results in establishing the "time zero" at the time the LCO was initiallynot met, instead of at the time that. Condition Awas entered.

AC Sources - Operating B 3.8.1 BASES ACTIONS (continued)
B.4 Based on the diversity of AC electrical power sources, and the remaining redundancy and reliability, operation may continue in Condition B for a period that should not exceed 14 days.
In Condition B, the. remaining GPERABLE DGs and offsite circuits are adequate to supply electrical power to the onsite Class 1E Distribution System.
The 14 day Completion Time takes into
)
account the capacity and capability of the remaining AC sources, reasonable time for repairs, and low probability of a DBAoccurring during this period.
The second Completion Time for Required Action B.4 establishes a limiton the maximum time allowed for any combination of required AC power sources to be inoperable during any single contiguous occurrence of failing to meet the LCO. IfCondition B is entered while, for instance, an offsite circuit is inoperable and that circuit is subsequently restored OPERABLE, the LCO may already have been not met for up to 7 days.
