5 3/4.0 APPLICABILITY BASES J.. A ; ',

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.b.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 1 This . specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.

c3.0.3 This specification delineates the ACTION to be taken for circumstances not directly provided for in the ACTION statements and whose occurrence would violate .the intent of the specification. For example, Specification 3.5.1

-requires each-Reactor Coolant System accumulator to be OPERABLE and provides explicit ACTION requirements if ^ one ' accumulator is inoperable. Under the terms. of . Specification 3.0.3. , if more than one accumulator is inoperable, within-one hour measures must be initiated to place the unit in at least HOT STANDBY within -6.-Sours and in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months . As a further example,' Specification 3.6.2.1' requires two Quench 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

- roquired Quench Spray Systems are inoperable, within one hour uneasures must be initiated to place the unit in at least HOT STANDBY within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , in at

'least HOT SHUTDOWN within the following 6' hours, and in at least COLD SHUTDOWN

'in the next 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

l 3.0.4- This specification provides that entry into an OPERATIONAL MODE or

'other specified applicability . condition must be made with (a) the full

. complement of. required. systems,. equipment or components OPERABLE and (b) all s jother parameters as specified in the Limiting Conditions for Operation being W met without - regard for allowable deviations and out of service provisions contained in the ACTION' statements.

4 The ; intent of this provision is to - insure that facility operation is not initiated with either required equipment or systems inoperable or other specified. limits being exceeded.

DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGES

h -

By_our letter dated December 15, 1983 (Serial No. 707), we proposed Technical

~

. Specification changes for North Anna Unit Nos. I and 2 to revise Technical Specification 3.0.3 and the Bases related to Technical Specification 3.0.3.

, The_ proposed changes were to provide consistency in relation to the time requirements of the Standardized Technical Specifications for Westinghouse Pressurized Wat'r reactors. In this submittal we proposed some hybrid changes such'that the lead-in to the action statement was different' than the standard; specificallylfrom a previously approved version of the North Anna 1 Technical

-Specifications. This was brought to the attention of Vepco by the NRC Project Manager for North Anna.

The ' proposed supplemental changes will revise . North Anna 1 and 2 Technical

-Specification 3.0.3 to partially state, "When a Limiting Condition for Operation . is not met, except - as provided in the associated ACTION requirements, within one hour ACTION shall be initiated to place the unit in a LMODE in which the Specification does not apply by placing it, as applicable,

.in:

1. . At least. HOT STANDBY within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months ,

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

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

^ In addition,' the Technical . Specification Bases have been revised to provide consistency with the changes to Technical Specification 3.0.3.

These supplemental. changes are to provide consistency in relation to._the time requirements of the Standardized Technical Specifications for Westinghouse LPressurized. Water Reactors, Revision 4, issued Fall, 1981.

The' proposed changes do not pose a significant hazards consideration as stated LinEthe Federal- Register. . dated April 6, 1983, Page 14870, Example (vii); a

. change to make a license conform to changes in the regulations, where the

" license change results in very minor changes to facility operations clearly in _

. keeping with the regulations. The regulation that is referred to for these

,c changes is NUREG-0452, Revision 4.
