4.0 Surveillance Reauirement Aeolicability 4.0.1 Surveillance requirements shall be met during the modes or other specified conditions in the applicability for individual LCOs, unless otherwise stated in l the surveillance requirements. Failure to meet a surveillance, whether such

! failure is experienced during the performance of the surveillance or between performances of the surveillance, shall be failure to meet the LCO. Failure to perform a surveillance within the specified frequency shall be failure to meet the LCO except as provided in 4.0.2. Surveillances do not have to be performed on l inoperable equipment or variables outside specified limits.

l l 4.0.2 If it is discovered that a surveillance was not performed within its specified frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is less. This delay period is permitted to

, allow performance of the surveillance.

1 If the surveillance is not performed within the delay period, the LCO must immediately be declared not met, and the applicable condition (s) must be entered.

l When the surveillance is performed within the delay period and the surveillance is not met, the LCO must immediately be declared not met, and the applicable condition (s) must be entered.

l BASES: Surveillance Requirement 4.0.1 establishes the requirement that surveillance requirements must be met during the modes or other specified conditions in the applicability for which the requirements of the LCO apply, unless otherwise

specified in the individual surveillance requirements. This specification is to ensure that surveillances are performed to verify the OPERABILITY of systems and components, and that variables are within specified limits. Failure to meet a surveillance within the specified frequency constitutes a failure to meet an LCO.

l Systems and components are assumed to be OPERABLE when the associated surveillance requirements have been met. Nothing in this specification, however, is to be construed as implying that systems or components are OPERABLE when:

a. The systems or components are known to be inoperable, although still meeting the surveillance requirements; or l Oyster Creek 4.0-1 t

l-l

'. )

1

! b. The requirements of the surveillance (s) are known to be not met between l required surveillance performances.

l l Surveillances do not have to be performed when the unit is in a mode or other specified condition for which the requirements of the associated LCO are not l applicable, unless otherwise specified. 1 Surveillances, including surveillances invoked by required actions, do not have i to be performed on inoperable equipment because the actions define the remedial measures that apply. Surveilleices have to be met and performed I prior to returning equipment to OPERABLE status. I Upon completion of maintenance, appropriate post maintenance testing is required to declare equipment OPERABLE. Thb includes ensuring applicable surveillances are not failed. Post maintenance testing may not be possible in the  !

current mode or other specified conditions in the applicability due to the l necessary unit parameters not having been established. In these situations, the l I

equipment may be considered OPERABLE provided testing has been l

satisfactorily completed to the extent possible and the equipment is not otherwise believed to be incapable of performing its function. This will allow operation to proceed to a mode or other specified condition where other necessary post maintenance tests can be completed.

Surveillance Requirement 4.0.2 establishes the flexibility to defer declaring l affected equipment inoperable or an affected variable outside the specified limits when a surveillance has not been completed within the specified frequency. A delay period of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is less, applies from the point in time that it is discovered that the surveillance has not been performed and not at the time that the specified frequency was not met.

This delay period provides adequate time to complete surveillances that have been missed. This delay period permits the completion of a surveillance before complying with required actions or other remedial measures that might preclude completion of the surveillance.

The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the .

t Oyster Creek 4.0-2

surveillance, the safety significance of the delay in completing the required surveillance, and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the requirements.

When a surveillance with a frequency based not on time intervals, but upon specified unit conditions or operational situations, is discovered not to have been performed when specified, Surveillance Requirement 4.0.2 allows the full delay period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to perform the surveillance.

Surveiilance Requirement 4.0.2 also provides a time limit for completion of surveillances that become applicable as a consequence of mode changes imposed by required actions.

l Failure to comply with specified surveillence frequencies is expected to be an infrequent occurrence. Use of the delay pedod established by Surveillance Requirement 4.0.2 is a flexibility which is not intended to be used as an operational convenience to extend surveillance intervals.

If a surveillance is not completed within the allowed delay period, then the equipment is considered inoperable or the variable is considered outside the specified limits and the completion times of the required actions for the applicable LCO conditions begin immediately upon expiration of the delay period. If a surveillance is failed within the delay period, then the equipment is inoperable, or the variable is outside the specified limits and the completion times of the required actions for the applicable LCO conditions begin immediately upon the failure of the surveillance.

Completion of the surveillance within the delay period allowed by this specification, or within the completion time of the actions, restores compliance with Surveillance Requirement 4.0.1.
