2-Management Interview Mr. Lenardson conducted a management interview on December 7, 1971, with the following people present.
F. J. McElroy, SN&P QA/QC Manager L. F. Sadowski, SN&P QA Engineer A. M. Vuksan, Bechtel Resident Inspector W. V. Moring, TECO QA Engineer Items of concern discussed were as follows:
A.
Mr. Lenardson stated that the seismic calculations, required by the specifications to be complaced prior to the start of fabrication, appeared not to have been completed until after completion of fabrication.
Mr. McElroy explained that the various specification requirements made it appear so.
(Paragraph 4)
B.
Review of fabrication process sheets and completed work documents by Mr. Moring revealed an apparent discrepancy in that welding procedures specified were not utilized.
Mr. McElroy explained that this was a result of welding procedure quality upgrading.

SECTION II Additional Subjects Inspected, Not Identified in Section I, Where No Deficiencias or Unresolved Items Were Found 1.
General The CO inspector accompanied the licensee representatives to observe their audit techniques and practices in performing a final QA audit survey to establish the quality acceptability of component cooling heat exchangers. The heat exchangers have been completed and delivered to the Davis-Besse site and have been placed on a " hold status" pending the results of this QA audit survey.
I 2.
The licensee representatives reviewed the following areas and found them to be free of deficiencies or unresolved problem areas:
a.
QA/QC organization and reporting point b.
Audits and management reports c.
Traceability d.
Procedure review e.
Document control f.
NDT control, including training, testing, and certification of personnel g.
Calibration control i
h.

Vendor audit and vendor program survey forms c.
Purchase order and specifications e
d.
Approved vendor QA manual and procedures e.
Codes and standards invoked by the purchase order and specifications Details of Subjects Discussed in Section I 4.
Mr. Lenardson stated that, as a result of his preaudit review, it appeared that the seismic calculations, required by the specification to be completed prior to the start of fabrication, had not been completed until completion of fabrication.
Mr. McElroy explained
/'"'N that, in following the specification stipulations, prior approval by
(
)
TECO of the calculations was not required. Therefore, although the subject calculations were completed in proper sequence, the table of document submittals placed the calculations among those items to be submitted upon completion of fabrication.
Mr. Lenardson acknowledged that his audit. review of engineering documentation had established that these calculations were completed in the proper sequence.
5.
A review of the fabrication process sheets and the heat treat records by Mr. Moring revealed a discrepancy with respect to welding procedure used (No. 516 A R1) versus the welding procedure specified (No. 516 R1).
Mr. McElroy explained that:
(1) procedure No. 516 A R1 is a modification of procedure No. 516 R1 which was
'ade after issuance of the fabrication process sheets; (2) this m
procedure modification was to add preheat and post heat treatment only.
. a quality upgrading of the original procedure; (3) heat treatment records establish that the new procedure was used; and (4) the procedure change therefore, enhances rather than degrades quality.
Mr. Lenardson and Mr. Moring accepted Mr. McElroy's explanation as being adequate to remove concern on their part.
