P.O. Box 101, New Hill, NC 27562 September 26, 1984 Mr. James P. O'Reilly NRC-274 United States Nuclear Regulatory Commission Region II 101 Marietta Street, Northweet'(Suite 2900)
Atlanta, Georgia 30323 CAROLINA POWER & LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT 1986 - 900,000 KW - UNIT 1 IN-CORE FLUX MAPPING SYSTEM -
SYSTEM INTERACTIONS, ITEM 179
Dear Mr. O'Reilly:
On June 22, 1984, Mr. N. J. Chiangi notified the NRC (Mr. D. Verrelli) of a potentially reportable item per the provisions of 10CFR50.55(e) and 10CFR, Part 21.
The NRC was informed that the interaction scenario postulating portions of the nonsafety flux mapping system falling on the in-core instrumentation tubing / seal table during a seismic event has not been adequately considered by Westinghouse.
In our letter dated July 19, 1984, we informed you that CP&L was currently waiting on Westinghouse to perform a structural integrity analysis for the portion of the in-core flux mapping system that is located above the in-core instrumentation tubing / seal table.
It was projected that the analysis would be received and a report on the reportability issued by September 30, 1984.
It is currently projected that Westinghouse will require until December 1984 to complete their evaluation. The final report on the reportability of this item is projected to be issued by January 15, 1985.
Thank you for your consideration in this matter.
Yours very truly, M
eM R. M. Parsons Project General Manager Shearon Harris Nuclear Power Plant RMP/j ed cc: Messrs. G. Maxwell /R. Prevatte'(NRC-SHNPP)
