Dear Sir or Madam:

By letter (Reference 1), Entergy Operations, Inc. (Entergy) proposed a change to the Waterford Steam Electric Station, Unit 3 (Waterford 3) Operating License and Technical Specifications to increase the unit's rated thermal power level from 3441 megawatts thermal (MWt) to 3716 MWt.

As committed to in Reference I and mentioned in Reference 2, Entergy performed confirmatory testing of the emergency Diesel Generator (DG) fuel oil consumption rate to validate the consumption rate assumed in the analysis supporting the Extended Power Uprate (EPU). During reviews of these test results, Entergy discovered that instrument uncertainties had not been adequately addressed in the supporting analysis and therefore the assumptions used in support of the EPU were non-conservative. As a result, a revised basis for showing that acceptable fuel oil inventories are available in support of the EPU based on the existing licensing basis has been provided for NRC staff review in Reference 3. Therefore, the information in Reference 3 supersedes information regarding the use of a DG fuel oil consumption rate less than that provided by the vendor previously submitted in Reference 1 (i.e., portions of Section 2.5.8.1 in Attachment 5) and Reference 2 (i.e., the response to Question 10 in Attachment 1).

oc

W3Fl-2004-01 07 Page 2 of 3 Post-EPU DG load summaries are attached to this letter providing updated information and supercede the load summaries previously provided in Reference 2. For comparison, the pre-EPU DG load summaries are located in Final Safety Analysis Report Table 8.3-1.

The no significant hazards consideration included in Reference 4 is not affected by any information contained in this letter. There are no new commitments contained in this letter.

If you have any questions or require additional information, please contact D. Bryan Miller at 504-739-6692.

I declare under penalty of perjury that the foregoing is true and correct. Executed on October 29, 2004.

Sincerely, TGM/dbm
