Allegation Group: QA/QC No. 5A Repair, Rework, Maintenance 2.

Allegation Number: AQ-130 3.

o pe In assessing this allegation, the TRT reviewed procedures CP-CPM-9.18, Revision 0, and QI-QAP-11.1.39A, Revision 3, concerning valve disassembdly/

reassembly and verified that the program for control of valve repairs was-adequate. The TRT reviewed the repair travelegspciped,githptQ the 53 valves that had been repaired between July #and October 1983;A Th

repair travelers required the QC inspector to record either the disc serial number or heat number on the traveler. On one traveler the QC inspector recordedtheassemblynumberforthediscandstudassembly,insteadof the serial or heat number.

In this instance, the number recorded differed from the matertal heat number recorded on the valve code data report, giving rise to the error alleged. However, the repair traveler providing the detailed instructions for repair of the valves required the parts to e traveler be packaged and tagged after dis sseg no g s required the inspector to verifyA hat the parts removed from the valve were reinstalled after repairs were made.

In all five travelers reviewed, this reinstallation was verified and signed off as acceptable by construc-tion and QA/QC. These additional checks and balances in the Mechanical Equipment Valve (MEV) traveler system helps to maintain traceability, even if a recordin'g error occurs in the inprocess paperwork.
