Letter, Entergy to USNRC, "Vermont Yankee Nuclear Power Station, License No. DPR-28, License Renewal Application," BVY 06-09, dated January 25, 2006.
Dear Sir or Madam:
On January 25, 2006, Entergy Nuclear Operations, Inc. and Entergy Nuclear Vermont Yankee, LLC (Entergy) submitted the License Renewal Application (LRA) for the Vermont Yankee Nuclear Power Station (VYNPS) as indicated by Reference 1.
During the NRC review of the VYNPS LRA, Entergy is required by 1 OCFR54.21 (b) to report changes to the current licensing basis (CLB) that materially affect the content of the VYNPS LRA, including the Safety Analysis Report (SAR) supplement. This information is required to be submitted annually and at least three months prior to the scheduled completion of the NRC review. In accordance with the requirements of 10 CFR 54.21(b), Entergy has completed a review and LRA impacts are discussed in Attachment 1 of this letter.
There are no new regulatory commitments being made in this letter.
Should you have any questions or require additional information concerning this submittal, please contact Mr. David J. Mannai at 802-451-3304.
I declare under penalty of perjury, that the foregoing is true and correct.
Executed on December 30, 2009 Sincerely,
[MJC/PLC]

LRA Notes for Table 3.5.2-1 througqh 3.5.2-6, Plant-specific notes, (Pg. 3.5-49) is revised to add the following.
505 Aging effects are not expected for fiberglass reinforced plastic (FRP). However, the identified AMP will be used to confirm the absence of significant aging effects for the period of extended operation.
BVY 09-073 / Attachment 1 / page 2 of 4 LRA Table 3.3.2-13-18, House Heating Boiler System An engineering change added a copper alloy valve to the house heating boiler system. The valve is exposed to a treated water environment.
The aging management review results for this component are the same as the entries for tubing with the same material environment combination as shown in the same LRA table. Reference page 3.3-185 of the LRA. LRA Table 3.3.2-13-18 is revised as shown below.
