Final Report Concerning.
W. J. Woolley. Company's Quality Assurance Documentation Description of the Problem -
A review of ' the welding and. in-process-~ records available at W...'J.
Woolley Company's Canton, Ohio, facility was. performed during the week of. April 4,.
1983..
.The. review indicated discrepancies in the quality assurance documentation records for the' fabrication of certain equipment manufactured by Irwin Steel Company.
The Irwin Steel Company was subsequently acquired by W.
J. Woolley Company.
The following equipment was manufactured - by the Irwin Steel Company and supplied to Nine Mile Point - Unit 2.
1.
Combination; equipment hatch and personnel airlock 2.
Equipment hatch 3.
Escape airlock 4.
Control rod drive removal hatch l
S.
Suppression pool access hatches'(2) i a
i All of the equipment,.with 'the exception of the personnel _ airlock, has been j
installed and is embedded in the primary containment concrete structure.'
The available records were reviewed for compliance to Irwin Steel Company's Quality Assurance Manual, Revision 8, dated May 5,-1978, which was the manual in effect during fabrication.
The ' following types of discrepancies were indicated.
1.
Contrary to the requirement in Irwin Steel Company's quality i
assurance manual, weld cards were not available for certain components.
2.
Welder qualification maintenance records were not available to show that the welders maintained their. qualification by performing the welding process within. a : 6-month : period-prior to the*use. of -the welding process in certain applicrtions.
The welder's ~. original.
qualifications were.on file except for one welder.
t 3.
Inconsistencies were. observed between. weld. maps, developed to coordinate the various parameters (e.g., weld number, welder number, weld procedure used, non-destructive-test? report number).and the cross-referencing documents.

From Various. magnetic particle test rep 3rts, 'it appears as if the testing was_ performed on a date prior to the date of the weld cards.

Analysis of Safety Implications _
A detailed investigation of -additional Woolley - documentation
( e. g.',
- reports, in-process' data
- sheets, certified material test ~ reports) and Woolley manufacturing practices was perfomed.
In i
addition, an engineering evaluation was performed of the welds for which i
discrepancies could not be resolved from. the above investigation.
The I
evaluation indicates :that the subject welds / components are technically
. acceptable as is and. could not have adversely affected the. safety of operations of the plant.
Therefore, - the criteria for reportability have not -
been met.
