Surveillance Requirements shall be appliccio during the OPERATIONAL MODES or 4.o.1 other conditions specified for individual Umiting Conditions for Operation unless otherwise stated in an indMdual Surveillance Requirement.

4.0.2 Each Surveillance Requirement shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25 percent of the surveillance

interval, 4.0.3 Failure to perform a Surveillance Requirement within the allowed surveillance interval, defined by Specification 4.0.2, shall constitute noncompliance with the operability requirements for a Umiting Condition for Operation. The time limits of the action statement requirements are applicable at the time it is identified that a surveillance requirement has not been performed. The action statement requirements may be delayed for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to permit the completion of the surveillance when the allowable outage time limits of the action statement requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

i ACTION statements for each of the applicable LCOs. However, the provisions of Specificatie l

3.0.5 permit the time limits for continued operation to be consistent with the ACTIC statement for the inoperable normal power sources instead, provided the other specified conditions are satisfied, in this case, this would mean that for one division the emergency power source must be OPERABLE (as must be the components supplied by the emergency power source) and all redundant systems, subsystems, trains, components, and devices in the other division must be OPERABLE, or likewise satisfy Specification 3.0.8 (i.e., be capable of performing their design functions and have an emergency power source OPERABLE). In other words, both emergency power sources must be OPERABLE and all redundant systems, subsystems, trains, components, and devices in both divisions must also be OPERABLE. If I

i these conditions are not satisfied, shutdown is required in accordance with this specification, in MODES 5 or 6, Specification 3.0.5 is not applicable, and thus the individual ACTION t

statements for each applicable Limiting Condition for Operation in these MODES must be i

adhered to.

4.0.1 This. specification provides that surveillance activities necessary to insure the L

Limiting Conditions for Operation are met and will be performed during the OPERATIONAL

[

MODES or other conditions for which the Limiting Conditior'4 for Operation are applicable.

l l.

Provisions for additional surveillance activities to be performed without regard to the L

applicable OPERATIONAL MODES or other conditions are provided in the individual

)

l Surveillance Requirements. Surveillance Requirements for Special Test Exceptions need only j

be performed when the Special Test Exception is being utilized as an exception to an individual specification.

i 4.0.2 This specification establishes the limit for which the specified time interval for Surveillance Requirements may be extended. It permits an allowable extension of the normal surveillance interval to facilitate suNeillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the suneillance; e.g., transient conditions or other ongoing surveillance or maintenance activities.

It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18. month surveillance interva8. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling 1:

outages. The limitation of Specification 4.0.2 is based on engineering judgement and the recognition that the most probable result of any particular sumeillance being performed is the verification of conformance with the Surveillance Requirements.

This provision is sufficient to ensure that the reliability ensured through sumeillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.

4.0.3 This specification establishes the fai;ure to perform a Surveillance Requirement within the allowed surveillance inteNal, defined by the provisions of Specification 4.0.2, as a condition that constitutes a failure to meet the operability requirements for a Limiting NORTH ANNA.

APPUCAtiLITY BASES (Continued)

Condition for Operation. Under the provisions of this specification, systems and components are assumed to be operable when surveillance requirements have been satisfactorily performed within the specified time interval. However, nothing in this provision is to be

. construed as implying that systems or components are operable when they are found or l

known to be inoperable although still meeting the surveillance requirements.

This 1

specification also clarifies that the action statement requirements are applicable when Surveillance Requirements have not been completed within the allowed surveillance interval and that the time limits of the action statement requirements apply from the point in time it is identified that a surveillance has not been performed and not at the time that the allowed surveillance interval was exceeded. Completion of the surveillance requirement within the allowable outage time limits of the action statement requirements restores compilance with the requirements of Specification 4.0.3.

However, this does not negate the fact that the failure to have performed the surveillance within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, was a violat6n of the operability requirements of a Umiting Condition for Operation. Futher, the failure to perform a surveillance within the provisions of Specification 4.0.2 is a violation of a Technical Specification requirement and is, therefore, a reportable event under the requirements of 10CFR50.73(a)(2)(1)(B) because it is a condition prohibited by the plant's Technical Specifications.

1 If the allowable outage time limits of the action statement requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or a shutdown is required to comply with action statement requirements, e.g.,

Specification 3.0.3, a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance is provided to permit a delay in implementing the l

action statement requirements.

This provides an adequate time limit to complete surveillance requirements that have not been performed. The purpose of this allowance is to permit the completion of a surveillance before a shutdown is required to comply with action statement requirements or before other remedial measures would be required that may ll preclude completion of a surveillance. The basis for this allowance includes consideration for plant conditions, adequate planning, availabliity of personnel, the time required to perform the survalliance, and the safety significance of the delay in completing' the required surveillance if a surveillance is not completed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance, the time limits of the action statement requirements are applicable at the time. When a surveillance is performed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance and the surveillance requirements are not met, the time limits of the action statement requirements are applicable at the time that _ the surveillance is terminated.

Surveillance requirements do not have to be performed on inoperable equipment because the action statement requirements define the remedial measures that appply.

However, the l

surveillance requirements have to be met to demonstrate that inoperable equipment has been restored to operable status.

4.0.4 This specification ensures that the surveillance activities l

associated with a Limiting Condition for Operation have been performed within the specified time interval prior to entry into an OPERATIONAL H0DE or other applicable condition. The intent of this provision is to ensure that surveillance activities have been satisfactorily demonstrated on a current basis as required to meet the OPERABILITY g

requirements of the Limiting Condition for Operation.

Under the terms of this specification, for example, during initial plant startup or following extended plant outaoes, the applicable surveillande activities must be performed within the stated surveillance

' interval DMor to placina or returning the system or equipment into OPERABLE status.

4.0.5 This specification ensures that inservice inspection of ASME Code Class 1, 2 and 3 components and inservice testing of ASME Code Class 1, 2 and 3 pumps and valves will be performed in accordance l

with a periodically updated version of Section XI of the ASME Boiler L

and Pressure Vessel Code and Addenda as required by the 10 CFR 50.55a.

Relief from any of the above requirements has been provided in wirting by the Connission and is not a part of these Technical Specifications.

This specification includes a clarification of the frequencies for performing the inservice inspection and testing activities required by Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda. This clarification is provided to ensure consistency in surveillance intervals throughout these Technical Specifications and to remove any ambiguities relative to the frequencies for performing the required inservice inspection and testing activities.

Under the terms of this specification, the more restrictive requirements of the Technical Specifications take precedence over the ASME Boiler and Pressure Vessel Code and applicable Addenda.

For example, the requirements of Specification 4.0.4 to perform surveillance acti-i' vities prior to entry into an OPERATIONAL MODE or other specified applicability condition takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows pumps to be tested up to one week after return to normal operation. And for example, the Tech-nical Specification definition of OPERABLE does not arant a grace oeriod before a device that is not capable of performing its specified function is declared inoperable and takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows a valve to be incapable of performing its specified function for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before being declared inoperable.

Specification 4.0.2 is a violation of a Technical Specification requirement and is, therefore, a reportable event under the requirements of 10CFR50.73(a)(2)(l)(B) because it is a condition prohibited by the plant's Technical Specifications.

if the allowable outage time limits of the action statement requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or a shutdown is required to comply with action statement requirements, e.g.,

Specification 3.0.3, a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance is provided to permit a delay in implementing the action statement requirements.

This provides an adequate time limit to complete surveillance requirements that have not been performed. The purpose of this allowance is to permit the completion of a surveillance before a shutdown is required to comply with action i

stat.ement requirements or before other remedial measures would be required that may preclude completion of a surveillance. The t, asis for this allowance includes consideration for plant conditions, adequate planning, availability of personnel, the time required to perform L

L the surveillance, and the safety significance of the delay in completing the required surveillance, if a surveillance is not completed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance, the time limits of the action statement requirements are applicable at the time. When a surveillance is performed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance and the surveillance requirements are not met, the time limits of the action statement requirements are applicable at the time that the surveillance is terminated.

l Surveillance requirements do act have to be performed on inoperable equipment because the action statement requirement.s define the remedlel measures that apply.

However, the surveillance raquirements have to be met to demonstrate that inoperable equipment has been restored to operable status.

BASES 4.0.4 This specification ensures that the surveillance activities associated with a Limiting Condition for Operation have been performed within the specified time interval prior to entry into an OPERATIONAL MODE or other applicable condition. The intent of this provision is to ensure that surveil-lance activities have been satisfactorily demonstrated on a current basis as required to meet the OPERABILITY requirements of the Limiting Condition for Operation.

Under the terms of this specification, for example, during initial plant startup or following extended plant outages, the applicable surveillance activities must ce performed within the stated surveillance interval prior to placing or returning the system or equipment into OPERABLE status, 4.0.5 This specification ensures that inservice inspection of ASME Code i

Class 1, 2 and 3 components and inservice testing of ASME Code Class 1, 2 and 3 pumps and valves will be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda i

as required by 10 CFR 50.55a.

Relief from any of the above requirements has been provided in writing by the Commission and is not a part of these Technical Specifications.

This specification includes a clarification of the frequencies for l

-performing the inservice inspection and testing activities required by Section XI of the ASME Boiler and Pres,sure Vessel Code and applicable Addenda.

l-This clarification is provided to ensure consistency in surveillance intervals

'l1 thoughout these Technical Specifications and to remove any ambiguities relative to the frequencies for performing the required inservice inspection and testing activities.

Under the terms of this specification, the more restrictive requirements l

of the Technical Specifications take precedence over the ASME Boiler and L

Pressure Vessel Code and applicable Addenda.

For example, the requirements of Specification 4.0.4 to perform surveillance activities prior to entry into an OPERATIONAL MODE or other specified applicability condition takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows pumps to be tested up to one week after return to normal operation.

And for example, the Technical Specification definition of OPERABLE does not grant a grace period before a device that is not capable of performing its specified function is declared inoperable and takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows a valve to be incapable of performing its specified function for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before being declared inoperable.
