Draft RAI for NTTF 2.1 Flooding Hazard Reevaluation Report Attachments: Draft RHMB RAI_Catawba.docx

Larry, The NRC staffs draft RAI for the subject activity is attached to this e-mail. The draft RAI is not an official NRC staff request and is being provided to you to facilitate a subsequent conference call to determine: 1) If the questions clearly convey the NRC staff information needs; 2) Whether the regulatory basis for the questions is understood; and 3) Whether the information is already available in existing, docketed, correspondence. After youve had a chance to review the draft information request, please contact me to schedule the conference call. Thanks.
