-INTRODUCTION By letter dated November 16,1983,' South Carolina Electric and Gas Company
~~
(SCE&G)-requested a revision to the Technical Specifications of the Virgil C. Sumer Nuclear Station. The. requested revision was in Technical Specifi-cation Table 3.7-4b, " Safety Related Mechanical Snubbers."' However.-
. Generic Letter 84-13, " Technical Specifications for Snubbers " was issued j
on May 3, 1984. This' letter permitted the deletion of both Tables i
3.7-4a, " Safety-Related Hydraulic Snubbers," and 3.7-4b, " Safety-Related Mechanical Snubbers" from present Technical Specifications of all Power Reactor Licensees (except Systematic Evaluation Program Licensees) and all applicants for licenses to operate power reactors. Therefore, SCE&G revised its request, by letter dated Decembe'r 14,.1984, to dele ~te both Tables 3.7-4a and 3.7-4b from the Technical Specifications.
II.
-EVALUATION-As stated in Generic Letter 84-13, the snubber listing currently found in Technical Specifications is not necessary, provided Technical Specification 3/4.7.7 specifies which snubbers are required to be operable. Therefore.
Technical Specification 3/4.7.7 is also being revised to indicate that all snubbers on systems required for safe shutdown / accident mitigation shall be operable. This includes safety and non-safety related snubbers on systems used to protect the code boundary and to ensure the structural integrity of these systems under dynamic loads.
Therefore, the requirement regarding snubbers found it) Technical Specifi-cations is not being changed, the revision is consistent with the NRC guidance stated in Generic Letter 84-13, and is acceptable to the NpC staff.
III. ENVIRONMENTAL CONSIDERATION This amendment involves a change in the use of a facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite and that there is no sig. ificant increase in individual or cumulative occupational radiation exposure.
The Comission has pre-viously issued a proposed finding that this amendment involves no signifi-cant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for 5
i
l' categorical exclusion set forth in 10 CFR Sec. 51.22(c)(9). Pursuant to
~
10 CFR 51.22(b) no environmental impact statement or environmental assess-ment need be prepared in connection with the issuanch of this amendment.
IV.
CONCLUSION The Commission made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Register (50 FR 8007) on February 27, 1985, and consulted with the state of South Carolina. No public comments were received, and the state of South Carolina 'did, not have any comments.
We have-concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the will not be endangered by operation in the proposed manner, and (2) public such activities will be conducted in compliance with the Commission's regula-tions and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
