I 3/4.0 APPLICABILITY BASES

The scecifications of this section provide the general requirements apoli-i cable to each of the Limiting Conditions for Operation and Surveillance Require-jmentswithinSection3/4.

I

3.0.1 This specification defines the applicability of each specification in terms of defined OPERATIONAL fiODES or other specified conditions and is nro-vided to delineate specifically when each specification is applicable.

i 3.0.2 This specification defines those conditions necessary to constitute 3

conoliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.

3.0.3 This soecification delineates the ACTION to be taken for circum-l stances not directly provided for in the ACTION statements and whose occurrence l would violate the intent of the specification. For example, Specification 3.5.1

calls for each Reactor Coolant System safety injection tank to be OPERABLE and I provides explicit ACTI0f! requirements when one safety injection tank is inoper-able. Under the terms of Specification 3.0.3, if more than one safety injection tank is inonerable, the facility is required to be in at least HOT STAND 3Y within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and in 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 />. As a further liil example, Specification 3.6.2.1 requires two Containment Soray Sys

! I ABLE and provides explicit ACTION recuirements if one spray system is inoperable:

i ! Under the terms of Specification 3.0.3, if both of the required Containment Spray

{ ] Systems are inoperable, the unit is required to be in at least HOT STANDBY within i 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, in at least HOT SHUTDOWN within the folloenng 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 il l

SHUTD0'lN in the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. It is assumed that the unit is broucht to the re-quired MODE within the required times by promotly initiating and carrying out the appropriate ACTION statement.

,i 3.0.4 This specification provides that entry into an OPERATIONAL tt0DE or l l other specified applicability condition must be made with (a) the full comple-l l ment of required systems, eauipment or components OPERA 3LE and (b) all other

. parameters as soecified in the Liniting Conditions for Operation being met with-it out regard for allowable deviations and out of service provisions contained in

, the ACTION statements.

The intent of this provision is to insure that facility operation is not

initiated with either required equipment or systems inoperable or other sneci-

. fied limits beis.g exceeded.

i Exceptions to this nrovision have been provided for a limited number of

, specifications when startup with inoperable equipment would not affect olant

safety. These exceptions are stated in the ACTION statements of the approori-

, ate specifications.

3/4.0 APPLICABILITY BASES

, 3.0.5 This specification delineates what additional conditions must be j satisfied to nemit operation to continue, consistent with the ACTION state-

ments for power sources, when a nomal or emergency power source is not OPERA-

! BLE. It specifically prohibits operation when one divisio'1 is inocerable be-

! cause its nomal or emergency power source is inoperable and a system, subsys-I tem, train, component or device in another division is inonerable for another reason.

The provisions of this specification oermit the ACTION statements associated with individual systems, subsystems, trains, components, or devices to be con-sistent with the ACTION statements of the associateo electrical power source.

It allows operation to be governed by the time limits of the ACTION statement associated with the Limiting Condition for Operation for the nomal or emer-gency power source, not the individual ACTION statements for each system, sub-system, train, component or device that is detemined to be inoperable solely because of the inoperability of its nomal or emergency power source.

For example, Specification 3.8.1.1 reouires in part that two emergency diesel cenerators be OPERABLE. The ACTION statement nrovides for a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> out-of-service time when one energency diesel generator is not OPERABLE. If the def-inition of OPERABLE were applied without consideration of Specification 3.0.5, all systems, subsystems trains, conponents and devices supplied by the inocera-ble emergency power sour,ce would also be inoperable. This would dictate invok-ing the applicable ACTION statements for each of the applicable Limiting Condi-l tions for Operation. However, the provisions of Specification 3.0.5 pemit the i

time limits for continued operation to be consistent with the ACTION statement I

for the inoperable emergency diesel generator instead, provided the other speci-

! fied conditions are satisfied. In this case, this would mean that the corre-sponding normal power source must be OPERABLE, and all redundant systems, sub-systems, trains, components and devices must be OPERABLE, or otherwise satisfy Soecification 3.0.5 (i.e., be capable of performing their design function and l have at least one nomal or one emergency oower source OPERABLE). If they are

not satisfied, shutdown is required in accordance with this specification.

! j As a further example, Soecification 3.8.1.1 reouires in part that two ohysically

• lClassIEdistributionsystembeOPERA3LE.

i independent circuits between the offsite The ACTION statement orovides a 24

! hour out-of-service time when both required offsite circuits are not OPERABLE.

; If the definition of OPERABLE were aoolied without consideration of Specifica-i j tion 3.0.5, all systems , subsystems, trains, components and devices sucolied i b l i y the inoperable normal power sources, both of the offsite circuits would also i;lbeinoperable. This would dictate invoking the applicable ACTION statements for each of the applicable LCOs. However, the orovisions of Specification 3.0.5 per-

, mit the time limits for continued operation to be consistent with the ACTION state-l ment for the inoperable nomal power sources instead, provided the other snecified conditions are satisfied. In this case, this would mean that for one division the I emeroencv power source must be OPERABLE (as must be the components suonlied by the

' ' emergenc'y power source) and all redundant systems, subsystems, trains, comnonents i

I :' CALVERT CLIFFS-UNIT 2 4 i B 3/4 0-2 l

!  ! BASES i

F; and devices in the other division must be OPERABLE, or likewise satisfy Specifi-

> cation 3.0.5 (i.e., be capable of performing their design functions and have an

. emeroency power source OPERABLE). In other words, both emergency oower sources

} , must be OPERA 3LE and all redundant systems, subsystems, trains, components and i ' devices in both divisions must also be OPERABLE. If these conditions are not

satisfied, shutdown is required in accordance with this specification.

t In MODES 5 or 6 Soecification 3.0.5 is not applicable, and thus the individual

.

• ACTION statements for each applicable Limiting Condition for Operation in these

MODES must be adhered to.

I

4.0.1 This specification provides that surveillance activities necessary

'l ' to insure the Limiting Conditions for Operation are net and will be performed during the OPERATIONAL MODES or other conditions for which the Limiting Condi-j tions for Operation are applicable. Provisions for additional surveillance ac-tivities to be perfomed without regard to the applicable OPERATIONAL MODES or other conditions are provided in the individual Surveillance Reouirements.

i 4.0.2 The provisions of this specification provide allowable tolerances for perfoming surveillance activities beyond those specified in the nominal

. , surveillance interval. These tolerances are necessary to orovide operational 1

flexibility because of scheduling and performance considerations.

The tolerance values, taken either individually or consecutively over 3

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.

l 4.0.3 Tne provisions of this specification set forth the criteria for j ' detemination of compliance with the OPERABILITY requirements of the Limitinc l!, Conditions for Operation. Under this criteria, equipment, systems or compo-i nents are assumed to be OPERABLE if the associated surveillance activities l ' have been satisfactorily perfomed within the specified time interval. Nothing

! in this provision is to be construed as defining equipment, systems or compo-

! nents OPERABLE, when such items are found or known to be inocerable although j still meeting the Surveillance Requirements.

4.0.4 This specification ensures that the surveillance activities as-

sociated with a Limiting Condition for Operation have been oerfomed 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-i lance activities have been satisfactorily demonstrated on a current basis as

reouired to meet the OPERABILITY requirements of the Limiting Condition for

Opera tion.
