DISCUSSION OF PROPOSED TECHNICAL SPECIFICATION CHANGES t.
The proposed changes to the North Anna Unit 1 Technical Specifications are to expand and clarify the ACTION requirements of Technical Specification 3.6.1.3,' Containment Air Locks. In addition, a lootnote has been added to surveillance requirement 4.6.1.3b to make the provisions of Specification 4.0.2 not applicable. These . revisions will provide consistency betwe an
- the North Anna 1 and 2 Technical Specifications and also with the
, Standardized Technical Specifications (STS) for Westinghouse PWR's, Revision 4 and Revision 5, Draft. The addition of the footnote also provides consistency between the Unit 1. Unit 2, STS and' the requirements of 10 CFR 50, Appendix J.-
A change to surveillance requirement 4.6.1.3a' is being proposed for North Anna Uniti Nos. 1 and 2. The proposed change is in the surveillance requirement for door seal leakage. The~ proposed change will reduce the amount of maintenance required on the containment air locks. By reducing the amount of maintenance required, the amount of ' personnel radiation exposure will be reduced.
4 Surveillance testing of the air- lock seals will continue to assure that the overall air. lock leakage will not become excessive due to seal damage
.during the ' intervals between air lock leakage test's. The overall air lock '
leakage limit' of 5 0.05 L g and the total type B and C leakage limit of 1 '
O.60 _ L , _will be unchanged. The proposed surveillance requirement for door seal . leakage limit _ of s - 0.01 L ,1s a small _part of either of the
, above limits and therefore does not constitute a significant change to the r-k
Technical Specifications.
It has been determined that an "unreviewed safety question," as defined in 10CFR50.59, does not exist because:
- a. This change does not increase the probability of occurrence or the consequences of an accident or malfunction of equipment important
. to safety and previously evaluated 'in the final safety Analysis Report. The surveillance frequency remains unchanged, and the Air Lock leakage limits insure overall air lock integrity.
- b. This change does not create a possibility for an accident or malfunction of a different type than any evaluated previously in the Final Safety Analysis Report. No physical or operational feature of the Air Lock is altered.
- c. This change does not reduce the margir of safety as defined in the basis of any Technical Specificat. ion. The overall air lock leakage and the tote,1 type B and C test leakage limits established in 10CFR50 Appendix J remain unchanged. "
The proposed changes to Technical Specification 3.6.1.3 have be-en determined not to pose a significant hazards consideration as stated in the Federal' . Register dated April 6,
~
1983. Example vil of examples of amendments that are considered not'11kely to involve a significant hazards ~
l l consideration states, "A change to make a license conform to changes in i
~
7
- v -* - ,.
- the regulations, where the license change results in very minor changes to
~
~
facility operations clearly in . keeping with the regulations". The proposed- changes are consistent with' the Standardized Technical
. Specifications for Westinghouse PWR's, Revision 4 and Revision 5, Draft.
