VERMONT YANKEE NUCLEAR POWER CORPORATION P. O. BOX 157 GOVERNOR HUNT ROAD VERNON, VERMONT 05354 VYN- 5709 June 25, 1980 United States Nuclear Regulatory Commission Office of Inspection and Enforcement Region I 631 Park Avenue King of Prussia, Pennsylvania 19406 Attention: Boyce H. Grier, Director
Reference:
a) Operating License DPR-28 (Docket No. 50-271) b) Reportable Occurrence No. RO 79-25/1T c) IE Information Notice No. 80-02 d) GE affidavit MFN 295-79 , Janice S. Chainley to F. D. Coffman, dated 12/11/79
Dear Sir:

SUBJECT:
Water Rod Lower End Plug Wear, RO 79-25/lT, Supplement I. I This letter provides supplemental information to reference (b) previously l requested during a meeting with Vermont Yankee, the NRC staff and General Electric on December 11, 1979.
Attached is a loose parts analysis developed by GE which addresses the possibility that the water rod lower end plug would wear to an extent that the shank would break. Vermont Yankee has reviewed this analysis and concurs with the stated conclusions that generation of a loose par is not expected and if a loose part is generated there would be no unacceptabl ensuing consequences.
Please note that the analysis has been determined to be neral Electric Company Proprietary Information and an Affidavit presented t NRC with GE slide material on 12/11/79 at the above noted meeting also applies to this analysis.
See reference (d).
We trust the above supplied information is satisfactory; however, should you. desire any additional information, please contact us.
Very truly yours, Aco) 5 Vermont Yankee Nuclear Power Corporation Warren . Murph Plant uperintend -
