Carolina Power 8 Light Company February 22, 1980 Mr. James P. O'Reilly United States Nuclear Regulatory Commission Region II 101 Marietta Street, Northwest Atlanta, Georgia 30303 SHEARON HARRIS NUCLEAR POWER PLANT UNITS 1, 2, 3, & 4 DOCKET NOS. 50-400, 50-401, 50-402, 50-403 DEFECTIVE SEISMIC CLASS I HANGER WELDS OPEN ITEM 400 401/79-23-05

Dear Mr. O'Reilly:

On November 26, 1979, CP&L had notified the NRC (Mr. R. Bradley) by telephone that the subject deficiency had been evaluated and considered to be reportable under the provisions of 10CFR50.55(e). As indicated to the NRC (Mr. R. Bradley) by telephone on February 19, 1980, further evaluation has now revealed that the subject deficiency is no longer considered reportable under the provisions of 10CFR50.55(e) on the basis that metallurgical investigation indicates that the types of defects noted were basically cosmetic and considered minor in nature and are not significant enough to cause subsequent failure. Based on the above, Carolina Power & Light Company considers this matter closed.

be noted that all corrective action on the subject deficiency has been It should completed and found to be acceptable.

If you have any questions regarding this matter, please do not hesitate to contact me.

Yours very truly, KVH/bd (6526)
