3/4. 0 APPLICABILITY BASES The specifications of this section provide the general requirements applicable to each ot the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4.
3.0. 1 This specification defines
~he applicability of each specification in terms of defined OPERATIONAL MODES or other specified conditions and is providedto delineate specifically when each specification is applicable.
3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates the measures to be taken for circumstances not directly provided for.in the ACTION statements and whose occurrence would violate the intent of a specification.
For example, Specifi-cation
- 3. 6. 2. 1 requires two containment spray systems to be OPERABLE and provides explicit ACTION requirements if one spray system is inoperable.
Under the terms of Specification 3.0.3, if both of the required containment spray systems are inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> measures must be initiated to place the unit in 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 />, and in COLD SHUTDOWN in the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
3.0.4 This specification provides that entry into an OPERATIONAL MODE or other specified applicability'condition must be made with (a) the full com-plement of required
- systems, equipment, or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.
The intent of this provision is to ensur e that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded.
1 Exceptions to this specification have been provided for a limited number of specifications when startup with inoperable equipment would not affect plant safety.
These exceptions are stated in the ACTION statements of the appropriate specifications.
PALO VERDE - UNIT 1 8 3/4 0-1 AMENDMENT'NO. 19
BASES 4.0. 1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for Operation are met and will be performed during the OPERATIONAL MODES or other conditions for which the Limiting Condi-tions for Operation are applicable.
Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL MODES or other conditions are provided in the individual surveillance requirements.
Surveillance requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to an individual specification.
- 4. 0.2 The provisions of this specification provide allowable toler ances for performing surveillance activities beyond those specified in the nominal surveillance interval.
These tolerances are necessary to provide operational flexibilitybecause of scheduling and per Pormance considerations.
The phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent surveillance activities.
The tolerance
- values, taken either individually or consecutively over three test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval; 4.0.3 The. provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation.
Under these criteria, equipment,
- systems, or components are assumed to be OPERABLE if the associated surveillance aotiv-ities have been satisfactorily. performed within the specified time interval.
Nothing in this 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 BASES The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4.
3.0. 1 This specification defines the applicability of each specification in terms"of defined OPERATIONAL MODES or other specified conditions and is provided to delineate specifically when each specification is applicable.
3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates the measures to be taken for circumstances not directly provided for in the ACTION statements and whose occurrence would violate the intent of a specification.
For example, Specifi-cation 3. 6. 2. 1 requires two containment spray systems to be OPERABLE and
.p'rovides explicit ACTION requi rements if one spray system is inoperable.
Under the terms of Specification 3.0.3, if both of the required containment
,: spray systems are inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> measures must be initiated to place the unit in 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 />, and in COLD SHUTDOWN in the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
3.0.4 This specification provides that entry into an OPERATIONAL MODE or other specified applicability condition must be made with (a) the full com-plement of required systems, equipment, or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.
The intent of this provision is to ensure that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded.
Exceptions to this specification have been provided for a limited number of specifications when startup with inoperable equipment would not affect plant safety.
These exceptions are stated in the ACTION statements of the appropriate specifications.
- PALO*VERDE - UNIT 2 B 3/4 0-1 AMENDMENT NO. 10
BASES
- 4. 0. 1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for Operation are met and will be. performed during the OPERATIONAL MODES or other conditions for which the Limiting Condi-tions for Operation are applicable..
Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL MODES or other conditions are provided in the individual surveillance requirements.
Surveillance requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to an individual specification.
4.G.2 The provisions of this specification provide allowable tolerances for performing surveillance activities beyond those specified in the nominal surveillance interval.
These tolerances are necessary to provide operational
'lexibility 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 surveillance activities.
The tolerance
- values, taken either individually or consecutively over three test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval.
4.0.3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Oper ation.
Under these criteria, equipment,
- systems, or components are assumed to be OPERABLE if the associated surveillance activ-ities have been satisfactorily performed within the specified time interval.
Nothing in this 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 APP LICABILITY BASES The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4.
- 3. 0. 1 This specification defines the applicability of each specification in terms of defined OPERATIONAL MODES or other specified conditions and is provided'o delineate specifically when each specification is applicable.
3.0,2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates the measures to be taken for circumstances not directly provided for in the ACTION statements and whose occurrence would violate the intent of a specification.
For example, Specifi-cation 3.6.2. 1 requires two containment spray systems to be OPERABLE and provides explicit ACTION requirements if one spray system is inoperable.
Under the terms of Specification 3.0.3, if both of the required containment
'pray systems are inoperable, within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> measures must be initiated to place the unit in 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 />, and in COLD SHUTDOWN in the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
3.0.4 This specification provides that entry into an OPERATIONAL MODE or other specified applicability condition must be made with (a) the full com-plement of required systems, equipment, or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.
The intent of this provision is to ensure that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded.
Exceptions to this specification have been provided for a limited number of specifications when startup with inoperable equipment would not affect plant safety.
These exceptions are stated in the ACTION statements of the appropriate specifications.

'3 3/4 0"1 AMENDMENT NO. 1
BASES 4.0.1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for Operation are met and will be performed during the OPERATIONAL HODES or other conditions for which the Limiting Condi-tions for Operation are applicable.
Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL HODES or other conditions are provided in <he individual surveillance requirements.
Surveillance requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to an indivitiual specification.
4.0.2 The provisions of this specification provide allowable tolerances for performing surveillance activities beyond those specified in the nominal surveillance interval.
These tolerances are necessary to provide operational flexibilitybecause 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 surveillance activities.
The tolerance
- values, taken either individually or consecutively over three test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval.
- 4. 0. 3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation.
Under these criteria, equipment,
- systems, or components are assumed to be OPERABLE if the associated surveillance activ-ities have. been satisfactorily performed within the specified time interval.
Nothing in this 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.
