Gordon, As a follow on to the email sent Thursday afternoon, the staff would like to add the attached question to the ones sent previously. Again, this email does not convey a formal NRC staff position, and it does not formally request information. Thanks.

DRAFT Need for clarification on Fire Protection Report

Gordon, In reviewing TVAs recent FPR submittal, the staff has come up with the attached questions. Please review to ensure that the questions are understandable, the regulatory basis is clear, there is no proprietary information contained, 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. This email does not convey a formal NRC staff position, and it does not formally request for additional information.

9. The description of Fire Area 2-1 (Part VI, Section 3.4.1, RHR Pump Room 1B-B) is, in part:

This is a separate fire area and the capability to achieve safe shutdown has been demonstrated through analysis. Yet, Part I, Table I-1 shows that Fire Area 2-1 has a III.G.1 Appendix R compliance strategy. This classification is only appropriate for fire areas that do not contain redundant trains of equipment or cables.

Does Fire Area 2-1 (RHR Pump Room 1B-B) contain redundant trains of equipment or cables? If so, identify the III.G compliance strategy of this fire area, and reference the appropriate evaluation deviation that addresses the analysis. If not, the description in the FPR of this area should be aligned with the other, similar fire areas (RHR Pump Room 1A-A, as an example).
