REQUIREMENTS source to transfer to. SR 3.8.1.9 and SR 3.8.1.10 are also not required to be met since the ability to respond to ES bctuations in other than MODES 1. 2. 3 or 4 is not a requirement for CR-3.

l SURVEILLANCE SR 3.8.2.1 (continued) i REQUIREMENTS source to transfer to. SR 3.8.1.9 and SR 3.8.1.10 are also not required to be met since the ability to respond to ES actuations in other than MODES 1, 2, 3 or 4 is not a requirement for CR-3.

This SR is modified by a Note. The NOTE indicates SRs 3.8.1.'3, and 3.8.1.11 are not required to be 3.8.1.3 performed to comply with SR 3.8.2.1. The reason for the Note is to preclude situations in which the OPERABLE EDG would be paralleled with the offsite power network or rendered inoperable during erformance of SRs. With limited AC sources available, a sin le event could compromise both the required offsite circui and the EDG. It is the intent but that these actual SRs mustisstill performance notbe capable ofRefer required. beingtomet, the Bases for LC0 3.8.1 for a discussion of each SR.

the impact of entering the ACTIONS of this l Additionally, Specificationduring Surveillance testing was evaluated as part of ITS implementation and a unique situation was discovered relative to the monthly EDG testing performed as part of surveillance procedures SP-354A and SP-354B and the MODES and Conditions addressed by this Specification. The EDG tear down and inspection is )eriodically performed during MODES 5 and 6 outages. T 1us it was concluded CR-3 couldcoincidentallyhaveonlyonedPERABLEEDGandbe required to perform SP 354. This created a concern since certain portions of SP-354 render the EDG inoperable, requiring entry into the ACTIONS of this Srecification.

RequiredActionB.3requiresactionbeinifiatedimmediately to restore the EDG to OPERABLE status. Thus, a situation is the ACTIONS ere established entered, SP-351 in which SP-354 is terminate is immediately performed,d (in order to restore OPERABILITY of the EDG). In this case, SP 354 could never be perfermed.

The need to perform SP 354 was evaluated in light of this concern. It was decided that since the periods of inoperability for the performance of the portions of SP-354 associated with SR 3.8.1.2 and 3.8.1.6 were brief and the SRs )rovided confidence in the OPERABILITY of the EDG, the SP siould be performed. Expeditiously performinc the portions of SP-354 associated with SR 3.8.1.2 anc 3.8.1.6 during these MODES satisfies the intent of Required Action B.3 and is therefore acceptable. For MODE 5 and 6 surveillance testing )erformed in accordance with SP-354 to meet SR 3.8.1.3 will )e performed at the frequency of SR 3.8.1.3 only when both EDG trains are operable.

RLFERENCES None.
