D.l Condition 0 applies to the following ESFAS Functions:

~Manual Initiation of SI;~Hanual Initiation of Steam Line Isolation; n~AFW-Undervoltage

-Bus 11A and llB.If a channel is inoperable, 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is allowed to restore it to OPERABLE status.The specified Completion Time of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is reasonable considering that there are two automatic actuation trains and another manual initiation channel OPERABLE for each manual initiation, Fun'ction additional AFW actuation channels available besides the Undervoltage

-Bus 11A and 118 AFW Initiation unctions, and the low probability of an event occurring during this interval.E.1 Condition E applies to the automatic actuation logic and actuation relays for the following ESFAS Functions:

~Steam Line Isolation;

~Feedwater Isolation; and~AFW.Condition E addresses the train orientation of the protection system and the master and slave relays.If one train is inoperable, a Completion Time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is allowed to restore the train to OPERABLE status.This Completion Time is reasonable considering that there is another train OPERABLE, and the low probability of an event occurring during this time interval.The Completion Time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is consistent with Reference 7.(continued)

R.E.Ginna Nuclear Power Plant B 3.3-95 Revision 0 ESFAS Instrumentation B 3.3.2 BASES ACTIONS (continued)

F.1 Condition F applies to the following Functions:

~Steam Line Isolation-Containment Pressure-High High;~Steam Line Isolation-High Steam Flow Coincident With Safety Injection and Coincident With T.,-Low;~Steam Line Isolation-High-High Steam Flow Coincident With Safety Injection; n~Feedwater Isolation-SG Water Level-High, Condition F applies to Functions that typically operate on two-out-of-three logic.Therefore, failure of one channel places the Function in a two-out-of-two configuration.

One channel must be tripped to place the Function in a one-out-of-two configuration that satisfies redundancy requirements.

If one channel is inoperable, a Completion Time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is allowed to restore the channel to OPERABLE status or to place it in the tripped condition.

Placing the channel in the tripped condition conservatively compensates for the inoperability, restores capability to accommodate a single failure, and allows operation to continue.The Required Actions are modified by a Note that allows the inoperable channel to be bypassed for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> for surveillance testing of other channels.This 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> applies to each of the remaining OPERABLE channels.The Completion Time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> allowed to restore the channel to OPERABLE status or to place the inoperable channel in the tripped condition, and the 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> s allowed for testing, are justified in Reference 7.(continued)
