3/4 LIMITING' CONDITIONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS 13/4.0 APPLICABILITY LIMITINC" CONDITION'FOR OPERATION 3.0.1 Limiting Conditions for Operation and ACTION requirements shall be

. applicable during the OPERATIONAL MODES or other conditions specified for each Specification.

3.0.2 L Adherence .to the requirements of the Limiting Condition for Operation and/or. associated - ACTION within the' specified time interval shall constitute compliance with the -Specification. In the event the Limiting Condition for Operation is restored prior to . expiration of the specified time interval, completion of the ACTION statement is not required.

3.0.3. When a. Limiting Condition for Operation inn not met, except as provided

.in the associated ACTION requirements, the unit shall be placed in a MODE in which the Specification does not apply by placing it, as applicable, in:

-1. At least HOT STANDBY within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />,

2. At least HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and

3. At least COLD SHUTDOWN within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.  ;

Where. corrective measures are completed that permit operation under the ACTION requirements, the ACTION may be taken in accordance with the specified time limits as measured from the time of failure to meet the Limiting Condition for Operation. -Exceptions to these requirements are stated in the individual Specifications.

3.0.4 Entry into an OPERATIONAL MODE or other specified applicability condition shall not be made unless the conditions for the Limiting Condition for Operation are met without reliance on provisions contained in the ACTION statements unless otherwise excepted. This provision shall not prevent passage through OPERATIONAL MODES as required to comply with ACTION statements.

3.0.5 When a system, subsystem, train, component or device is determined to be inoperable solely because its emergency power source is inoperable cr solely ' because its normal power source is inoperable, it may be considered OPERABLE for .the purpose of satisfying the requirements of its applicable Limiting Condition for Operation, provided: (1) its corresponding normal or emergency power source - is OPERABLE;' and (2) s.11 of its redundant system (s),

subsystem (s), train (s) , component (s), and device (s) are OPERABLE, or likewise satisfy the requirements of this Specification. Unless both conditions (1) and (2) are satisfied, within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, ACTION shall be

initiated to place the unit in a MODE in which the applicable Limiting Condition for Operation does not apply by placing it so applicable, in

1. At least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />,

. DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANCES North Anna linit - 1 and ~2 Technical Specification. 3.0.5 currently states, "When s' system, subsystem, train, component or device-is determined to be inoperable solely because its. emergency power _. source is inoperable, or solely because its

", - normal ; power " source _ is inoperable, it may be considered OPERABLE for the

~

purpose of satisfyingi the requirements of its . applicable Limiting Condition for Operation, .provided: :(1) ~1ts corresponding normal - or emergency power 4

source fis OPERABLE; and - (2) all of its redundant system (s), subsystem (s),

itrain(s), components (s) and _ device (s) are OPERABLE, or likewise satisfy the.

requirements of ? this' specification.. Unless both conditions (1) and . (2) . are

satisfied, the unit-shall be placed in at least HOT STANDBY within 1-hour, in-1 at.least HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in at least COLD SHUTDOWN P _ Twithin the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.. This specification is not applicable in MODES

.5 or 6."

c,

, The ' proposed change wil11 require that conditions (1) and (2) be satisfied

. within .2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or ACTION 'shall be ' initiated to place the unit in a MODE in

. which' the applicable ' Limiting Condition for Operation does not apply by

placing it, as applicable, in:-

Ll., At least HOT.. STANDBY within the next-6 hours, At.least-HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and

.2.

3. At least COLD-SHUTDOWN within the subsequent 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

.This specification is not applicable in MODES 5 and 6.

The current I hour time limit to be in at least HOT STANDBY is more restrictive than' other . Technical Specification Limiting Conditions for iL Operation for. similar situations that allow 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to - be in at least- HOT -

i STANDBY.' This change will create greater operating flexibility and provide additional time for repairs prior to having to shutdown the unit.

This proposed-change does not-pose a significant hazards consideration. This

! change results in minor changes to facility operations ' and clearly keeps within regulations. ..Other operating plants - are operating with the less restrictive Limiting Condition for Operation.

The proposed change does not involve a significant increase in the probability

' .or consequences of an accident previously evaluated in the UFSAR and this change'does not create the possibility of a new or different kind of accident previously

evaluated in the UFSAR because the changes - are minor to facility l operation and they clearly keep within regulations. This change does not involve a significant reduction in the . margin of safety because the change provides consistency with other Limiting Conditions for Operation that have at

.least 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />s-to be in HOT' STANDBY.
