P. O. Box 101, New Hill, N. C. 27562 03 m 7 AIO : S S March 2, 1983 Mr. James P. O'Reilly NRC-45 United States Nuclear Regulatory Commission Region II 101 Marietta Street, Northwest (Suite 3100)
Atlanta, Georgia 30303 CAROLINA POWER & LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT 1986 900,000 KW - UNITS 1 & 2 WELDING DEFICIENCIES ON CLASS 1E BATTERY RACKS, PURCHASE ORDER NY-435065, ITEM 116 De . O'Reilly:
On January 31, 1983, Mr. N. J. Chiangi notified the NRC (Mr. A. Hardin) of a potentially reportable item per the provisions of 10CFR50.55(e). Mr. Hardin was informed that battery racks supplied by C&D Batteries for emergency batteries contained welding deficiencies. It was reported that this item was not reportable per the provisions of 10CFR, Part 21; however, after further evaluation, we think this item should be considered potentially reportable per the requirements of 10CFR, Part 21, as well as 10CFR50.55(e).
At the present time, we have initiated and completed rework of the deficient welds in order to make them consistent with C&D Batteries' acceptance criteria.
Ebasco is still evaluating the adequacy of the deficient welds and do not expect to be complete until May 1, 1983. For this reason, we request an extension until May 15, 1983 for submitting a report on the reportability of this item.
Thank you for your consideration in this matter.
Yours very truly, W ! =f R. M. Parsons Project General Manager Shearon Harris Nuclear Power Plant RMP/sh cc: Mr. G. Maxwell (NRC-SHNPP)
