Subject:

Vermont Yankee Nuclear Power Station License No. DPR-28 (Docket No. 50-271) 10CFR50.46(a)(3)(ii) Annual Report for 2007 This letter is to report, in accordance with 10CFR50.46(a)(3)(ii), changes in peak cladding temperature (PCT) for the Vermont Yankee (VY) Emergency Core Cooling System (ECCS) Loss of Coolant Accident (LOCA) analysis. This annual report covers VY Cycles 25 and 26 from.----

January 2007 to December 2007.

For Cycles 25 and 26, VY used the General Electric (GE) SAFER/GESTR methodology for the evaluation of the ECCS/LOCA. The results are summarized and reported in References (a), (b) and (c).

The licensing basis PCT, calculated for the GE14 fuel type VY currently has loaded in its core, including corrections through 2006, is documented in Reference (c).

In Cycle 26 VY loaded four GNF2 Lead Use Assemblies (LUAs) into the core. Since these assemblies were loaded as LUAs, the PCT change associated with these assemblies is not included in this annual report.

The following table updates the results to reflect subsequent changes to or errors identified in the methodology for the current VY fuel type. There were no new changes or error reports identified for VY fuel in 2007.

Adjusted Licensing Basis PCT 1960 Since the PCT for the GE14 fuel type is well within the acceptance criterion of 10CFR50.46(b)(l), there is no need for re-analysis or other action per 10CFR50.46(a)(3)(ii).

There are no new regulatory commitments being made in this submittal.
