By Reference (b), we submitted Proposed Change No. 108 to our facility Technical Specifications. This change reflected the addition and deletion of safety-related shock suppressors (snubbers) resulting from modifications made in conjunctio1 with our Mark I Containment Long-Term Program.

Page 116C has subsequently been revised to reflect the deletion of Snubber RHR-H188 This snubber is being removed coincident with our Mark I Program torus-attached piping modifications and will be replaced by a rigid restraint.

In addition, two (2) sets of snubbers identified as single snubbers, or single units, on Pages ll6b and e in our last submittal

United States-Nuclear Regulatory Commission August 4,1983 Attention:

Mr. Darrell C. Eishenhut Page 2 Safety Considerations:

The safety consideration for this change is consistent with that presented in Reference (b). Therefore, we have concluded that this change does not constitute an unreviewed safety question as defined in 10CFR50.59(a)(2) nor does It involve a significant hazards determination as defined in 10CFR50.92(c).

This submittal has been reviewed by the Vermont Yankee Nuclear Safety Audit and Review Committee.

Fee Determination:

This change is pro forma and administrative in nature, and has no safety or environmental significance. For these reasons, Vermont Yankee Nuclear Power Corporation proposes this as a Class II amendment. A payment of $1,200 was previously forwarded with Reference (b).

Schedule Of Change:

The change-described above will be incorporated into the Vermont Yankee Technical Specifications as soon as practicable following receipt of your approval.

We trust that this submittal will not impact the timely review of our proposed change; however, should you have any questions, please contact us.

Very truly yours,
