In the Matter of Docket No. 50-260 Tennessee Valley Authority BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 2 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME) SECTION XI r INSERVICE INSPECTION AND REPAIR AND REPLACEMENTS FOR CYCLE 9 OPERATION

SUMMARY

REPORTS In accordance with paragraphs IWA-6220 and IWA-6230 of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI, 1986 Edition (no addenda), TVA is submitting the BFN Unit 2 summary reports for NRC review.

The summary reports are for inservice inspection (NIS-1 Report), and repair and replacement activities (NIS-2 Report) for Unit 2 Cycle 9 operation.

TVA has determined that ten components had non destructive examination (NDE) coverage limitations (less than 90 percent coverage completed) which exceeds that specified in ASME.

Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division 1." The components are Reactor Pressure Vessel (RPV) nozzles (ASME Section XI Code Category BD, Nozzle-To-Vessel Welds) and had 980i260i03 980ii5 PDR ADQCK 05000260 6 P,DR

~I ~I J

U.S. Nuclear Regulatory Commission Page 2 January 15, 1998 calculated NDE examination coverage ranging between 65 and 77 percent completed. The limitations encountered during the performance of the ultrasonic (UT) examination

.were caused by component configuration. The nozzle contours limit the accessible UT examination volume. As a result, TVA will submit a request for relief to address the reduced NDE examination coverage for these components by April 3, 1998. contains the BFN Unit 2 inservice inspection summary report (NIS-1) for Code Class 1 and 2 pressure retaining'components and their supports. Enclosure 2 contains the repair and replacements report (NIS-2) for Code Class 1 and 2 components and supports. Additionally, provides a summary of the commitment contained in this letter.
