Introduction

The Safety Evaluation Report by the Division of Operating Reactors Supporting the Operation After the Restoration and Modification of the Browns Ferry Nuclear Plant Units 1 and 2 Following the March 22, 1975 Fire (SER) was issued on February 23, 1976. The SER identified matters requiring additional submittals by the Tennessee Valley Authority (TVA) with subsequent NRC evaluation. Since the date of the SER issuance, there have been meetings with TVA, additional revisions to the "Plan for Evaluation, Repair and Return to Service of Browns Ferry Units 1 and 2 (March 22, 1975 Fire)" dated April 13, 1975 (the Plan), and meetings with the ACRS resulting in an ACRS report dated March 11, 1976.

The purpose of this supplement is to update the SER based on the NRC evaluation work performed since February 23, 1976. The section numbers of this supplement are the section numbers of the SER wherein the matter was identified except for Sections 11, 12, 13, 14, 15 and 16. Section 11 discusses ACRS items which were identified for additional information or evaluation in the ACRS report dated March 11, 1976. Sections 12 through 16 are new sections. In addition, the supplement contains an updated chronology as Appendix A, the report of the Advisory Committee on Reactor Safeguards (ACRS) as Appendix B, a report by the Analytical Research Laboratories, Inc. on combustion test results for Flamemastic 71A as Appendix C, and a comparison of the Browns Ferry Plant with the "Recommendations Related to Browns Ferry Fire, Report by Special Review Group" (NUREG-0050) as Appendix D.
