Gentlemen.
,d\\
ir hb}e~p'\\ O The attached " Licensee ort" is submitted to report three events which occurred during the installation of equipment associ-ated with postulated high-energy line-break modifications. These three incidents were classified as reportable because as a group they may in-dicate the lack of adequate procedures for assuring that design reviews on items having safety significance are completed.
,m (V
Some difficulty was experienced in classifying these events
)
with regard to required reportability. An audit of modifications being performed at the Palisades Plant by our Quality Assurance Department re-sulted in the issuance of eight nonconformance reports. Of these eight, five were classified as "NRC reportable" by the Quality Assurance Depart-ment in accordance with 10 CFR 50 55 Further review by the Operations Department and Plant Review Committee resulted in the conclusion that none were required to be reported in accordance with the operating li-cense but that three would be reportable if the reporting definitions of Regulatory Guide 1.16, Revision 3, were in effect. 10 CFR 50.55 is not applicable after issuance of an operating license.
As three would be reportable if the reporting definition con-tained in Regulatory Guide 1.16, Revision 3, were incorporated into our operating license, the Plant Review Committee deemed it desirable to report these three nonconformances as a single unusual event requiring 30-day reporting.
Yours very truly, s
