DRAFT RAIs on Fire Protection - Group 8

Gordon, In reviewing the latest fire protection report, the staff has come up with the attached questions. Please review to ensure that the RAI questions are understandable, the regulatory basis is clear, there is no proprietary information contained in the RAI, and to determine if the information was previously docketed. If further clarification is needed, and you would like to discuss the questions in a conference call, let us know. Please also let me know how much time Tennessee Valley Authority (TVA) needs to respond to the RAI questions.

This email does not convey a formal NRC staff position, and it does not formally request for additional information.

RAI FPR VI-12 It is unclear to the reviewers why the Diesel Generator Building Pipe Gallery and Corridor (room 742.0-D9) was subdivided into three subsections (742.0-A, -B, -N) and two Analysis Volumes (AV-089A and -089B). Part VI, Section 3.59.3, of the FPR indicates that neither power supplies nor major equipment will be affected by a fire in either Analysis Volume. This does not align with the need to partition this room.

Provide an explanation for why this area was split up when the safe shutdown analysis was performed.
