The following subjects were discussed:
J A.
Results of Containment Building Post Tensioning The inspector stated he had reviewed the subcontractor's report and engineering study of post tensioned tendons and found that the engineer-
.
ing evaluation supported acceptance of individual tendons elongated in i
excess of the five percent allowed by ACI 318-63.

The licensee acknowledged this without comment.
B.

Control of Welding Material Used in Containment Liner Plate Welding
.
The inspector stated that welding material control documentation for
.
the containment liner plate had been reviewed and indicated that the others, attested to satisfactory control of weld materia
t used in the construction of the containment liner.
(Details Paragraph 3)
The licensee confirmed that their QA surveillance maintained during con-the containment liner plate erection.struction had found no deficien 7-3 O
Control'of Welding Material Used in Reactor Coolant Bleed Tanks C.
The inspector stated that welding material control records for the reactor purchase, receipt, coolant bleed tanks had been reviewed and that the d control of the weld material issued and used during constru containment liner.
(Details Paragraph 4)
The licensee accepted this with the comment that one audit report on welding documented the corrective action taken during construction to establish completely acceptable control of welding material.
D.
Reactor Vessel Sole Plate Fabrication and Installation The inspector stated that he reviewed the vendor's fabrication records on the reactor vessel sole plates, site records on receipt and storage, and the constructor's installation records.
No deficiencies were id entified.

Reactor Coolant Bleed Tank Record Deficiency
^
f]
The inspector stated that he reviewed the as-built construction drawings
for the reactor coolant bleed tanks and could find no correlation be-
'
tween the welds and the responsible welder's.
(Details Paragraph 6)
The licensee replied that this will be investigated to assure that complete documentation is available for the inspector's review at a sub-sequent inspection.

2.
Results of Containment Building Tendon Tensioning i
The prestress subcontrator's final report was submitted October 16, 1973.
(.)
It contains a summary of individual vertical, dome and horizontal tendons in containment building for Unit 1.
The reasons for discrepancies in elongation in the tendons have been analyzed as required by ACI 318.
l The final review concludes that loss of prestress due to broken or out-j of-tolerance wires is below the value of one-half (1/2) percent as i
allowed in specifications.
The constructor, the A-E and the licensee j
have concurred in the corrective action, disposition and have signed off all deviation reports on tendon tensioning.
3.
Control of Welding Material Used in Containment Liner Plate Welding Procedure WRC-ll, Revision 3, of the containment liner plate contractor, Chicago Bridge and Iron Company (IB&I) dated 11/11/69 requires that records of all weld rod received and verified mill certificates be kept at the job site.
The RO inspector's review found good trace-ability without deficiency in these records. The CB&I procedure additionally states that supervisory personnel and quality control personnel only will have access to electrode storage and be re-sponsible for issuing electrodes.
CB&I's welding supervisor is responsible for issue and temperature control of E-7018 electrodes for selection of the proper rod and control of weld rods in the work area.
Documentation of these requirements at the time the containment liner plate welding was presented were not required by specifications nor by the CB&I procedure. However, the RO inspector verified by surveillance and audit reports that the requirements of the CB&I procedures were met
~
and no weld rod control deficiencies were found.

Control of Welding Materici Used in Reactor Bleed Tanks
.
p Procedure DB 119-189, Revision dated 3/20/69, controlled the work on the g-)
reactor coolant bleed tanks fabricated at the site by the Pittsburgh-Des
Moines Steel Company (PDM).
The procedure requires that electrodes and s.
filler metal conforming to specific requirements be purchased in hermetical-
!
ly sealed containers from an approved supplier.
Procedural controls are established for issuance from containers, time out of container, holding oven temperature, and rebake temperature when electrodes are not dis-carded.
The RO inspector reviewed evidence that the specified electrodes were cbtained from an approved supplier, and that receiving inspection reports included chemical and physical test cerrifications for each order.
The job specifications and the PDM procedures in force at the time did not require that records be kept by PDM covering electrode issuance and field
,
-
control.
However, the RO inspector verified in audit reports by others that after some corrective action was taken, the specification and procedural re-quirements controlling the use of welding material were satisfactorily implemented, and no further deficiencies were identified.
