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 l
compliance with the terms of an _ individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates'the ACTION to,be taken for circumstances not directly provided for in the ACTION statements and whose occurrence vould violate the intent of the specification.
For exarple, Specification 3.5.1 calls for each Reactor Coolant System accumulator to be OPERABLE and provides explicit ACTION requirements when one accumulator is inoperable.
Under the 4
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 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 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 example, Specification 3.6.2.1 requires two Containment 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 ' required Containment Quench Spray Systems are inoperable, within one hour measures must be initiated to place the unit in at least HOT STANDBY j
within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, 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 />, and in at least COLD SHUTDOWN in the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 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 complement 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 insure that facility operation is not 3
~ or systems inoperable or other initiated with either required equipment j
specified limits being exceeded.
. Exceptions to this provision have been provided for a limited number of specifications when startup with ~ inoperable equipment would not affect plant i
safety.
These exceptions are stated in the ACTION ~ statements of the appropriate specifications.

-DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGES Currently, North Anna 1 Technical Specification 3.0.3 partially states, "In the event a Limiting Condition for Operation and/or associated ACTION require-ments cannot be satisfied. because of circumstances in excess of those addressed in the specification, the unit shall be placed in at least HOT
- STANDBY within I hour. 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.. within the~ following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> unless corrective measures are completed that permit operation under the permissible ACTION statements for the specified time interval as measured from initial discovery or until the reactor is placed in a MODE in which the specification is not applicable."
In Amendment No. 48 to the North Anna 1 Operating License, which does not become effective until January 1,
1984, Technical Specification 3.0.3 was revised. to partially read. "When a Limiting Condition for Operation is 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, b.
as applicable, in:
1.
At least HOT STANDBY within I hour; 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 l~
- 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 />."
Currently, North. Anna 2 Technical Specification 3.0.3 partially states, "When a Limiting Condition for Operation is not met, except as provided in the j
associated ACTION requirements, the unit shall be placed in a MODE'in which the specification does not apply by placing it, as applicable, in:
t
.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 ',0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />."
The proposed changes to Technical Specification 3.0.3, for North Anna 1 and 2, l
will partially state, '.'In the event a Limiting condition for Operation and/or associated ACTION requirements cannot be satisfied because of circumstances in p
excess'of those addressed in the Specification, within one hour ACTION shall l
be initiated to place'the unit in a MODE in which the Specification does not l
apply by placing it, 'as applicable. in:
- 1.. At least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 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 />."
In addition -the Technical Specification Bases has been revised to provide consistency with the changes to Technical Spec Hication 3.0.3.
6 These proposed changes to North Anna 1 and 2 Technical Specification 3.0.3 and Bases are needed to provide consistency in relation to the time requirements of the Standardized Technical Specifications for Westinghouse Pressurized Water Reactors, Revision 4 issued Summer,1980, NUREG 0452, Revision 4.
I
The proposed changes do not pose a significant hazards consideration as stated in the Federal Register, dated April 6, 1983 Page L4870 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 probability of occurrence or the consequences of a malfunction of equipment important to safety and previously evaluated in the UFSAR is not significantly increased, the possibility of a different type of accident or malfunction than was previously evaluated in the UFSAR has not been created and the margin of safety as described in the BASES section of any part of the Technical Specifications is not significantly reduced because the proposed changes are being made to keep North Anna Units 1 and 2 within regulations.
