Notification of Cancelled Regulatory Commitment Vermont Yankee Nuclear Power Station Docket No. 50-271 License No. DPR-28

1. Letter, VY to USNRC, "Update on Vermont Yankee Program Commitments Relative to Periodic Testing of Alternate AC Sources," BVY 08-043, dated August 14, 2008

Dear Sir or Madam:

In Reference 1, Vermont Yankee Nuclear Power Station (VY) made a commitment related to the testing of the Alternate AC (AAC) power source from the Vernon Hydro Station (VHS), as it applied to compliance with 10 CFR 50.63 (Station Blackout Rule). Specifically, Reference 1 committed to the following:

"Performload test of the alternate AC source every third refueling outage" This commitment is being cancelled as the VHS tie line is no longer relied upon as the AAC power source credited for compliance with 10 CFR 50.63 at VY.

By License Amendment No. 258 (Reference 2) the NRC approved a change to the VY licensing basis which credits a new Station Blackout Diesel Generator as the AAC source for compliance with the Station Blackout Rule, replacing the VHS tie line. Amendment No. 258 documented new commitments for testing of the Station Blackout Diesel Generator in the associated Safety Evaluation.

This letter serves to update the docket relative to our cancellation of a prior commitment.

No NRC action is requested on this issue.
