SUMMARY

OF TELEPHONE CONFERENCE HELD ON JULY 1, 2004, BETWEEN THE U.S. NUCLEAR REGULATORY COMMISSION (NRC) AND THE TENNESSEE VALLEY AUTHORITY (TVA) CONCERNING DRAFT REQUESTS FOR ADDITIONAL INFORMATION (D-RAI) ON BROWNS FERRY NUCLEAR PLANT UNITS 1, 2 AND 3 LICENSE RENEWAL APPLICATION (TAC NOS. MC1704, MC1705 AND MC1706)

The U.S. Nuclear Regulatory Commission staff and representatives of Tennessee Valley Authority (TVA or the applicant) held a telephone conference on July 1, 2004, to discuss the draft requests for additional information (D-RAIs) related to Sections 3.0, Appendix B, and Fire Protection Report (FPR) of the Browns Ferry Nuclear Plant (BFN) license renewal application.

BROWNS FERRY NUCLEAR, UNITS 1, 2 AND 3 LICENSE RENEWAL APPLICATION DRAFT REQUEST FOR ADDITIONAL INFORMATION (D-RAI)

FIRE PROTECTION ENGINEERING AND SPECIAL PROJECTS SECTION D-RAI Section 3.0 - Aging Management Review Results (1) LRA Table 3.5.2.2, Reactor Building - Summary of Aging Management Review, lists Coating (ALBI CLAD-161) as part of the fire barrier. This fire resistive coating for structural steel lists only for the Reactor Building in the table. It is unclear from the Fire Hazard Analysis (FHA) if this is the only building with structural steel protection. The table referred to Appendix B, Section B.2.1.23, which does not specifically address structural steel fire resistive coating (it may be implied as part of fire barriers). Identify all in-scope structures which contain fire resistive coatings on structural steel. Verify that ALBI CLAD-161 is the only material used for protecting steel. Identify how these materials are addressed in the AMP.

Discussion: The applicant indicated that the question is clear. This question will be reworded, renumbered, and sent as RAI 3.3-1 (2) LRA Table 3.5.2.2, Reactor Building - Summary of Aging Management Review, identifies ceramic fiber as having no aging effects and therefore requiring no AMP.

Provide the technical basis for this conclusion.

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI 3.3-2 (3) LRA Table 3.5.2.12 identifies Thermolag as a fire barrier and referred to LRA Appendix B, Section B.2.1.23. Cable wraps are not specifically addressed in Section B.2.1.23. Is this the only area of the plant where cable wrap fire barriers are used? Electrical raceway fire barriers are referenced in plant operating experience as experiencing minor degradation. Identify all areas where cable wraps are provided, and verify that these barriers are included in the AMP.

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI 3.3-3 D-RAI Appendix B - Aging Management Program Descriptions (1) Appendix B, Section B.2.1.23 Fire Protection Program, does not address what is included in the fire pumps and does not reference the electric pumps. The boundary drawings show the three electric and one diesel fire water pumps as in-scope. Verify that the electric fire pumps are included in the AMR and AMP. The smaller electric service water pumps are used for pressure maintenance, but are not shown in scope.

Justify why these pressure maintenance devices are not in-scope.

Enclosure 1

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI B.2.0-1 D-RAI Review of Fire Protection Report (FPR)

(1) Section 4.4.1.a of the FPR addresses a separate water supply system, including tank and pumps, which does not appear in the LRA or boundary drawings. Verify whether these system components are in scope and provide the justification if they are not.

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI 4.4.1-1 (2) Section 4.4.5 of the FPR states that Flammastic was applied to cables that did not meet IEEE-383 flame tests requirements. Inspection Testing and Maintenance (ITM) of this is not referenced in the FPR. No reference is made to it in the LRA, either under the Fire Protection Program, Section B.2.1.23, or in the electrical or structural programs.

Identify where these coating are addressed in the LRA scoping, screening and AMR.

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI 4.4.5-1 (3) Section 9.4.11.G of the FPR discussed semiannual inspection of fire doors to check closers and latching mechanisms. The LRA AMP has a vague reference to periodic visual inspections as an exception to the GALL, in LRA Section B.2.1.23. Explain how a visual inspection can verify the closer and latching mechanism. Verify that the frequency of these surveillance are consistent with the FPR.

Discussion: The applicant indicated that the question is clear. This question will be renumbered and sent as RAI B.2.0-2 LIST OF PARTICIPANTS FOR TELEPHONE CONFERENCES ON DRAFT REQUESTS FOR ADDITIONAL INFORMATION July 1, 2004 Participants Affiliation Yoira Diaz U.S. Nuclear Regulatory Commission (NRC)
