Letter, G02-06-139 dated November 20, 2006, JV Parrish (Energy Northwest) to NRC, "Proposed Schedule for License Renewal Application Submittal"

Dear Sir or Madam:

In accordance with the requirements of 10 CFR 51 and 10 CFR 54, Energy Northwest requests the renewal of the operating license for the Columbia Generating Station (Columbia).

The current Columbia operating license (Facility Operating Licenses NPF-21) expires at midnight on December 20, 2023. By this License Renewal Application (LRA), Energy Northwest seeks to extend the Columbia operating term by 20 years beyond the current expiration date, to midnight on December 20, 2043. This application also applies to the renewal of the source, special nuclear, and by-product materials licenses that are combined in the facility operating license. The LRA includes an environmental report, prepared in accordance with 10 CFR 54.23 and Subpart A of 10 CFR 51.Energy Northwest has determined that the LRA provides the appropriate administrative, technical, and environmental information sufficient to support the findings required by 10 CFR 54.29. Actions have been identified to manage the effects of aging on the structures and components subject to aging management review, such that the intendedfunctions will be maintained consistent with the current licensing basis during the Columbia period of extended operation (PEO).As required by 10 CFR 54.21 (b), current licensing basis changes that have a material effect on the content of the LRA will be identified in an amendment to the LRA that will be submitted at least annually while the LRA is under Nuclear Regulatory Commission (NRC) review and at least three months prior to the scheduled completion of the NRC review.cA-D_5 5 1J~A£.. )

Stainless The program includes: (a) identification of susceptible Steel (CASS) components determined to be limiting from the standpoint of Program thermal aging or neutron irradiation embrittlement (neutron fluence), (b) a component-specific evaluation to determine each identified component's susceptibility to loss of fracture toughness, and (c) a supplemental examination of any component not eliminated by the component-specific evaluation.
