Containment.
(Steel Structures and Su orts) - Observation of Work and Work Activities, Units 1 and 2 (Exce t Weldin
)
Graver Tank and Manufacturing Co.
(Graver)
had fabricated and delivered to the Harris site the steel containment liner plate segments, the polar crane support assemblies and the valve chambers for Units 1 and 2 and, apparently, most of the liner segments for L'nits
and 4.
Until transfer of the containment liner erection contract from Graver to CB&I, Graver had retained custody of materials and CP&L had provided required storage without making formal receiving inspections.
Receiving inspections have now been made for the Units
and
materials by Ebasco Services, CP&L and CB&1.
The liner segments as fabricated by Graver could not, in many cases, be utilized with the CB&l erection methods.
The discrepancies in dimensions, omissions of openings, joint preparation details, and damages received during handling and storage were tabulated in detail by Ebasco and CB&1.
Needed corrections have been documented on DDR's and NCR's.
After disposition of each has been determined, corrective action is to be performed by CB&I under CP&L survei)lance.
Note:
No receiving inspections nor official accounting has been made of materials for Units 3 and 4.
The inspector inspected the newly completed floor liner plate in L'nit
containment which included the Graver fabricated shear key pits.
installation of plates in the second course of the wall liner was observed.
The Graver supplied valve boxes for Unit
had been installed and Daniel workmen were correcting honeycomb voids in the surface of the concrete basemat adjacent to the valve chambers.

Welding of Containment Liner Seams Weld identification and location, joint preparation and alignment, and QC verification were observed for weld N (containment liner first ring to floor weld) and second ring vertical liner weld I, prior to and during welding.
Use of the appropriate welding procedure (7018(B)/84030),
welder qualifications (for welders J.N
, C.B.,
and G.W.A.), and use of the specified welding material (7018) were verified.
Inspection personnel were noted periodically observing the welding.
Recording of welding variable checks was verified.
Performance of required magnetic particle inspections on liner welds was not specifically observed, but was verified from discussions with inspection personnel and a review of the records.
Handling, storage, and issuance of welding material was
'lso examined.
This work was checked for compliance with the requirements of ASME Section III, Div. 2, Subsection CC (W75).
No deviations or items of noncompliance were identified.
Stud Welding on Liner Plate Stud welding on liner plate is required to comply with ASIDE Section III, Di v. 2, Subsection, CC (W75).
Compliance with the applicable identification, location, preparation, QC verification, welding procedure, inspection and welding material controls was checked for the stud welding observed during the NRC inspection.
Actions required prior to welding (location marking, preparation of weld area by grinding, etc.)
were specif>cally examined for plate 11B3.
Actual performance of welding and inspection was observed for liner plate 12B3.

Nos. 50-400/78-6, 50-401/78-6, 40-402/78-6 and 50-403/78-6 III-4 Containment (Liner Plate Vertical Seam Weldin
- Review of Qua1i tv Records Unit 1)
The records applicable to this welding must comply with ASME Section III, Div. 2, Subsection CC.
Weld history records
- including visual and dimensional inspection (on the CBSI Record Drawing Table),
magnetic particle inspection (CBSI MT Report 18), welder and welding materials identification, etc.,
were reviewed for the containment liner bottom ring vertical welds and several second ring welds.
Specific welder qualification records were examined for welders J.N., L.H., and C.B.
Applicable records for storage identification, and issue control of the welding materials were examined.
The issue control of the welding material for the liner seam welding is specified in CB&1 "Contract Quality Assurance Handbook, Contract 8403/1/2, Div. 4" (implementing the controls required by
CFR 50, ASME Section III, and licensee contractual documents).
The referenced CBRI document (in its Sect.
8.0 Welding, Rev.
7) requires sign-off entries for both issuance and return (or completed usage)
of welding electrodes on a "Daily Weld Distribution Log" (form WL180).
In examining the log record sheets the NRC inspector found that the sign-offs required to verify return or complete usage of electrodes (under the heading "Material Disposition Complete" ) were missing for one issuance on 9/21/78 and all issuances on 10/4/78.
There was no evidence to indicate that electrodes were actually being allowed to remain out uncontrolled.
This was apparently only a
documentation error.
The missing record entries are a noncompliance with Criterion V of 10 CFR 50 Appendix B, which the licensee implements as stated in Paragraph 1.8.5.5 of his PSAR.
This noncompliance is categorized as a deficiency and is identified for record as item 400/78-06-01.
One noncompliance, item 400/78-06-01, was found in this inspection.
No deviations were identified.
