In certain instances the requests for additional information (RAls) were modified based on clarifications and understandings reached during the telecons. The information provided herein is consistent with those understandings. to this letter provides Entergy's response to each of the RAls. Because certain RAI responses contain proprietary information as defined by 10CFR2.390, Attachment 1 has been designated in its entirety as proprietary information.

An affidavit that constitutes a request for withholding of the proprietary information in from public disclosure in accordance with NRC regulations is provided by the owner of the proprietary information (General Electric Company (GE)) as Attachment 3.
