3/4.0 LIMITING CONDITIONS FOR PDMS AND SVRVEILLANCE REQUIREMENTS l 3/4.0 APPLICABILITY l

l LIMITING CONDITIONS FOR PDMS t

! 3.0.1 Limiting Conditions for PDMS and ACTION requirements shall be l applicable during POST-DEFUELING MONITORED STORAGE or other conditions specified for each specification.

3.0.2 Adherence to the requirements of the Limiting Condition for PDMS and/or l associated ACTION within the specified time interval shall constitute i compliance with the specification. In the event the Limiting Condition for PDMS is restored prior to expiration of the specified time interval, completion of the ACTION statement is not required.

l 3.0.3 In the event a Limiting Condition for PDMS and/or associated ACTION requirements cannot be satisfied because of circumstances in excess of those  !

addressed in the specification, initiate appropriate actions to rectify the '

problem to the extent possible under the circumstances and submit a report to ,

the Commission pursuant to the requirements of 10 CFR 50.73. l l \

! SURVEILLANCE REQUIREMENTS l

4.0.1 Surveillance Requirements shall be met during PDMS or other conditions specified for individual Limiting Conditions for PDMS unless otherwise stated in an individual Surveillance Requirement. i 4.0.2 Each Surveillance Requirement shall be performed within the specified i

time interval with a maximum allowable extension not to exceed 25% of the l surveillance interval.

l 4.0.3 Failure to perform a Surveillance Requirement within the specified time interval shall constitute a failure to meet the OPERABILITY requirements for a l Limiting Condition for PDMS. Exceptions to these requirements are stated in the individual Specifications. Surveillance Requirements do not have to be performed on inoperable equipment.

l 4.0.4 If it is discovered that a surveillance was not performed within its l specified frequency, then compliance with the requirement to declare the LC0 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.

l CONTAINMENT AIR LOCKS LIMITING CONDITIONS FOR PDMS l 3.1.1.3 Each Containment Air Lock shall be OPERABLE with at least one door closed except when the air lock is being used for transit entry and exit in accordance with site-approved procedures.

APPLICABILITY: PDMS ACTION:

With no Containment Air Lock door OPERABLE, restore at least one door to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

I SURVEILLANCE RE0VIREMENTS '

4.1.1.3 Each Containment Air Lock shall be demonstrated OPERABLE annually by performing a mechanical operability check of each Air Lock Door, including a visual inspection of the components and lubrication if necessary and by visually inspecting the door seals for significant degradation. When both Containment Air Lock doors are opened simultaneously, verify the following conditions:

a. The capability exists to expeditiously close at least one Air Lock door; ,

b. The Air Lock doors and Containment Purge are configured to restrict the outflow of air in accordance with site-approved procedures; and

c. The Air Lock doors are cycled to ensure mechanical operability within seven days prior to opening both doors.

3/4.0 APPLICABILITY i BASES l i l

l l

The specifications of this section provide the general requirements applicable '

l to each of the Limiting Conditions for PDMS and Surveillance Requirements l l within Section 3/4.

l 3.0.1 This specification defines the applicability of each specification in terms of PDMS or other specified conditions and is provided to delineate specifically when each specification is applicable.

l 3.0.2 This specification defines those conditions necessary to constitute i

compliance with the terms of an individual Limiting Condition for PDMS and associated ACTION requirement.

3.0.3 The specification defines the action and reporting requirements for those circumstances where the ACTION statement for Limiting Conditions for PDMS was exceeded.

4.0.1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for PDMS are met and will be performed during the condition for which the Limiting Conditions for PDMS are applicable.

4.0.2 The provisions of this specification provide allowable tolerances for performing surveillance activities beyond those specified in the nominal I surveillance interval. These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations. The phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent l

surveillance activities. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified. The allowable tolerance is based on engineering judgement and the

, recognition that the most probable result of any particular surveillance being i performed is the verification of conformance with the Surveillance l Requirements. This provision is sufficient to ensure that the reliability l ensured through surveillance activities is not significantly degraded beyond I

that obtained from the specified surveillance interval.

l 4.0.3 The provisions of this specification set forth the criteria for l determination of compliance with the OPERABILITY requirements of the Limiting Conditions for PDMS. Under this criteria, equipment, systems or components l are assumed to be OPERABLE if the associated surveillance activities have been l satisfactorily performed within the specified time interval. Nothing in this I provision is to be construed as defining equipment, systems or components OPERABLE, when such items are found or known to be inoperable although still meeting the Surveillance Requirements.

3/4.0 APPLICABILITY (Con't)

BASES 1

4.0.4 This specification 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 l 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 /> applies from the point in time

, that it is discovered that the required surveillance nas not been performed and not at the time that the specified frequency was not met.

The delay period provides an 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 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, this provision 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.

Failure to comply with specified surveillance frequencies is expected to be an infrequent occurrence. Use of the delay period 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 l 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 failure of the surveillance.

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