COLUMBIA GENERATING STATION, DOCKET NO. 50-397 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION
Reference:
Letter No. G02-10-11, dated January 19, 2010, WS Oxenford (Energy Northwest) to NRC, "License Renewal Application"
Dear Sir or Madam:
In a December 13, 2010 telephone conversation with the NRC Project Manager for the Columbia Generating Station (Columbia) license renewal application, Energy Northwest committed to providing additional information regarding the environmental assessment of electric fields associated with the 11 5-kV transmission line that serves as a backup power source for the station.Included in Attachment 1 is the electric field profile for the 115-kV line. Also included in this attachment is information on conductor geometry.
For comparison, Attachment 2 includes similar information for the 230-kV and 500-kV lines that link Columbia to the Bonneville Power Administration's (BPA) H.J. Ashe Substation.
This information was obtained from the BPA and was used in the assessment of induced currents in Section 4.13 of the environment report that was submitted with the referenced letter.If you have any questions or require additional information, please contact Abbas Mostala at (509) 377-4197.A1H 3 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE RENEWAL APPLICATION Page 2 of 2 I declare under penalty of perjury that the foregoing is true and correct. Executed on the date of this letter.ectfully, S;Gambhir Vice President, Engineering Attachments:
