As of September 1979, the following reviews had been made. The September 9, 1979, inspec-tion by the NRC inspector still found discrepancies. The licensee then hired NES to re-review all reports for accuracy and radiographs for techniques only. As of December 9 1979, NES had reviewed 812 radiographic welds and found 509 unacceptable because of inaccurate reports or unacceptable radiographic techniques. There are approxi-mately 60 welds to be radiographed because of unacceptable techniques.
NES has approximately 2500 more radiographs to review and this will consist of interpreting the radiographs for weld quality and techniques and reviewing the reports for accuracy.
The radiographic film packages reviewed by the RIII inspector had been subjected to one or all of the following reviews:
a.
Peabody Magnaflux Corporation A Level I or Level II radigographer performed all the radiography and a Level II interpreted the radiographs for weld quality and techniques and completed the reports.
b.
Kaiser Engineers, Inc.
A radiographic film interpreter Level II interpreted the radio-graphs for weld quality and techniques and reviewed the reports for accuracy.

c.
The Authorized Nuclear Inspector
-
The ANII interpreted several radiographs for weld quality and technique and reviewed the reports for accuracy.
d.
OCONAM
'
A Level II radiographer was contracted to interpret several radiographs for weld quality and techniques and review the reports for accuracy.
The Cincinnati Gas & Ijectric Company e.
As of a result of the NRC noncompliance in December 1978, a cognizant engineer from the licensee's Quality Assurance Standards Section received each radiograph package prior to filing with the quality assurance records in accordance with the CG & E letter QA-1107. This consisted of a unqualified radiographer checking the reports for completeness and varifying that there were radiographs in the packages.
f.
Kaiser Engineers, Inc.
A radiographic film interpreter Level II, in some cases was the same individual that interpreted the radiographs months / years before, reviewed the radiograph packages critically prior to system turnover in accordance with the CG & E letter QA-1107.
This consisted of checking accuracy of the report and verifying that there were radiographs in the packages.
No items of noncompliance or deviations were identified.
Exit Interview The inspector met with site representatives at the conclusion of the in-spection. The inspector summarized the secpe and findings of the inspec-tion noted in this report.
