- Denotes those att'nding the exit interview on December 11, 1981.
e In addition Mr. W. G. Albert, NRC Senior Resident inspector attended the exit interview.
2.
Site Tour The inspector conducted a tour of Unit No. 3 on December 7,1981 to observe completed work, work in progress, and storage an1 maintenance of safety related equipment.
The inspector noted improved housekeeping in scme areas, notably. the reactor auxiliary building pipe chase and containment penetration areas.
Inprovement is still warranted in other areas, for example, in the vicinity of the shutdown heat exchanger 1B. The inspector noted improved protection and support of the outboard ends of containment penetrations.

Licensee Action on P'ievious Enforcement Items
'
,,
_
(Closed) - Noncompliance (50-508781-07/01)' - Failure to Qualify Fillet
?
Weld Procedu e Tre inspector had identified electrical cable tray' support welding performed outside of the variebles of the prequalified fillet weld procedure.
Licensee response to this item of noncompliance was stated in letter Nos. G03-81-2046 ar.d 003-81-2057 and included qualification of procedure Ho. AWS-1A to the AWS D.l.1 structural welding code.
.
The requirements for-minimum single pass fillet weld sizes have been added to Construction Procedure No. CP-403S, Weld Procedure No. AWS-1.
The successful qualification of Weld Procedure No. AWS-1A was used to justify acceptance of previous welds and corrective action included a
~
review of welder qualifications and welding procedure qualifications to ensure compatibility with existing contractor procedures, AWS D.1.l_,
and contract requirements.
The inspector examined the procedure qualification for Procedure AWS-1A against the requirements of AWS D.l.1, Table 5.10.3 2 nd found it acceptable. _ This item is considered closed.
5.
Licensee Action on Previous Followup, Items a.
(Closed). Followup Item (50-508/509/80-17/03) - Oualification of Welders Performing Flare Bevel Groove Welds.
The inspector had questioned whether welders performing flare bevel groove welds should be qualified on open butt,1oint-configuration or backing plate configurations.
Code inquiries were submitted both by the contractor and licensee on this issue. The ASME Code Comittee response indicates that welders may be considered' qualified to weld flare bevel groove welds when qualified on a backing plate configuration.
Rationale behind this interpretation apparently included the ease of access of the flare bevel configuration and the fact that these are partial penetration welds. This item is considered closed,

(Closed) Followup' Item (50-508/509/81-08/26) - Definitions of Major and Minor Design Changes Inconsistant throughout Ebasco Procedures.
The inspector had obsersed that the definition of major and minor design changes in the PSAR were not consistently applied throughout the Ebasco Company Procedures Manual. The inspector verified that this situation has been corrected by issuance of Ebasco Site Support Engineering Procedure No. C6-4, Revision 2, " Applicability of Company and Project Procedures to WNP-3/5".
6.
Steel Containment Vessel Embedded Penetration Nozzles The inspector examined correspondence between Ebasco engineering and Chicago Bridge and Iron Company.(CB&I) regarding failure to place a two inch thick compressible material around penetration Nos. 23, 24 and 44 prior to concrete placement to eliminate shear forces at the nozzle-to-shell interface. This deficiency appears to have resulted.from failure by the engineer to conform the construction specifications to the CB&I proposal which specified this requirement.
Ebasco has directed CB&I to analyze the shear forces at the embedded penetration nozzles and insert plates, determine the effect on the vessel, and update the stress report. CB&I responded with a request for design data which was furnished by Ebasco in letter No. EB213-81-72 dated December 4, 1981.
This letter transmitted data including the coefficient of friction between.the concrete and steel; concrete modulus of elasticity; Poisson's ratio, lump-mass model of the internal structure; maximum acceleration response for each mass point in all threa directions; and thermal gradient across the vessel shell at the embedment region.
The inspector questioned the design controls applied to this transmittal of design data for the following reasons:
The lump-mass model does not identify the project or client.
.
There was no evidence of approval of acceleration responses for
.
internal structures.
The thermal gradient data consists of a markup of data from another
.
plant without indication of the originator or checker.
The engineer could not determine the design control applied to this data since it originated in the New York Office.
The' inspector also questioned the controls applied to ensure that revisions or changes to any of this design data at'a later date will be identified to CB&I for reanalysis. This item will remain open pending examination of the controls applied to transmittal of design data in this manner.
Followup item (50-508/81-20-01).

Containment ~ (Steel ~ Structures and Supports) - Chicago Bridge and Iron Review of Quality Records The inspector examined _ records associated with the. containment polar crane girder against the requirements of the contract specification and PSAR. Records examined included the crane girder record drawing,
-crane girder assembly drawing, shop release for shipment, evidence of vendor quality assurance signoff, and field checklist. These records were examined for plate nos.15A(3) and 4 and weld nos. CG7A, CG78 and CG7A (R-1). -The~ inspector also verified implementation of a system to ensure magnetic particle examination of 15 percent of all "T" joints following post weld heat treatment.
No items of-noncompliance or deviations were identified.
8.
Management Meeting The inspector met with the licensee and management personnel denoted in paragraph 1 at the conclusion of the inspector on December 11, 1981.
The inspector discussed the scope and findings of the inspection.
The findings were acknowledged.by the licensee.
