'McGUIRE NUCLEAR STATION RESPONSE TO VIOLATION IN INSPECTION REPORT 50-369/86-18 AND 50-370/86-18 4
i Violation 50-370/86-18-02, Severity Level IV 10CFR50, Appendix B, Criterion V and XVI is implemented by Duke Power Company Topical Report Quality Assurance Program, Duke-1A, section 17.2.5 and 17.2.16 which in turn is implemented by Station Directive 2.0.4, QA Nonconforming Item Report and QCK-1 (Rev. 21), Control of Nonconforming Item. Collectively these documents require that activities affecting quality shall be accomplished in 1
accordance with procedures, instructions or drawings and that measures shall be established to assure that conditions adverse to quality such as nonconformances are promptly identified and corrected.
Contrary to the above, the licensee failed to follow procedures on approximately April 21, 1986, during reload of the Unit 2 core when an operations refueling senior reactor operator (SRO) noticed two or three irradiated specimen access hole plugs lying on the core barrel support ledge. No nonconforming item report was initiated to promptly identify and correct the problem.
Reload was continued and completed on April 23, 1986. Subsequently, the upper internals and reactor vessel head were installed with loose objects left in the reactor vessel.

Response
1.
Admission or denial of the alleged violation:
Duke Power admits the violation in that we concur that there was a failure to adequately follow up on identification and removal of the observed objects prior to reinstallation of the reactor vessel internals and head. We do not agree that generation of a nonconforming item report was the appropriate action in this situation. The SR0 had other mechanisms available to insure the situation was identified and corrected such as the SR0 logbook, the plant work request system and the test log for the core loading procedure.
2.
Reason for violation:
The violation was due to personnel error in that the SR0 failed to properly document and follow up on his observation of the objects.
3.
Corrective steps which have been taken and the results achieved:
i i
.The importance of properly following up on observed problems such as this has been covered with appropriate operations personnel. To prevent the i
possibility of these plugs becoming accidentally dislodged again, i
MP/0/A/7150/43, Upper Internals Removal and Replacement, was revised on May i
29, 1986 to required removal and storage of these plugs immediately following removal of the upper internals and reinstallation just prior to upper i
internals replacement. Please note that the inspector's statement in Section i
6 of 50-369/86-18 and 50-370/86-18 that reads "Also at the time of the l-l
' inspection,.there were no changes to procedures to correct tnis event from recurring" is an error as. the maintenance procedure had been revised following the event.
4.
Corrective steps which will be taken to avoid further violations:
No further corrective steps are necessary.
5.
Date when full compliance will be achieved:
McGuire Nuclear Station is present'ly in full compliance.
