- Attended exit interview 2.
Exit Interview The inspector met with licensee representatives, denoted in paragraph 1, at the conclusion of the inspection on July 12, 1979. The inspector summarized the scope and findings of the inspection of documentation for containment steel plates, safety relatedpipe welding, reactor coolant pressure boundary piping procedures, safety-related piping procedures, and welding of contain-ment structures. The licensee was advised that no items of noncompliance or deviations were identified during this inspection.

Licensee Action on Previous Inspection Findings Not inspected.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Documentation for Containment Steel Plates (Units A1, A2, B1 and B2)
a.
The inspector reviewed the ASME Code data reports for all of the stainless steel clad plates being utilized for construction of the lower two courses of the metal containment vessels.
The code appli-cable to these plates is ASME Section III, Subsection NE (74S74), with Code Case 1714. The Code requirements are implemented through C. F.
Braun Specification 300-13 Rev.
7.
Entries on the data report were examined to verify compliance with the applicable Code and specifica-tion requirements.
Within the areas inspected, no items of noncompliance or deviations were identified.

-2-b.
Safety-Related Pipe Welding The inspector observed two nearly completed welds and one fitup for welds in the Essential Service Water System (ESW). The applicable code for these welds is ASME Section III, Subsection ND (74S74). The welds were identified as follows:
Weld Identification Stage of Completion BIESW00001 Fitup and tacked only B2ESW00141 Welding nearly completed B2ESW00146 Welding nearly completed Control cards for the three welds were examined to verify compliance with the requirements of the licensee's procedure QCI W-101 Rev.
(with deviation dated 5/17/78). The welds and adjacent base metal were visually examined for compliance with the Code.
Within the areas inspected no items of noncompliance or deviations were identified.
6.
Reactor Coolant Pressure "cundary Piping - Review of Quality Assurance Implementing Procedures (Units A1, A2, B1 and B2)
The inspector reviewed the licensee's procedures relative to reactor coolant pressure boundary piping to verify compliance with the PSAR QA r20 gram in the area of piping installation (exclusive of welding related activities).
The procedures were specificaly examined for provisions applicable to location, clearances, hangers and supports, insulation, NDE, hydrostatic testing, control of cold spring and installation records. Procedures reviewed which contained provisions applicable to the above items were as follows:

The inspector noted that while certain items for which the procedures were examined are not specifically addressed in the procedure.s (e.g., cold spring) they are normally addressed in specifications or drawings and the
" Work Package" (CEP-5.04) provides a means for transmitting the require-ments to the craftsmen and inspector performing the work.
Within the areas inspected, no items of noncompliance or deviations were identified.
7.
Safety-Related Piping - Review of Quality Assurance Implementing Procedures (Units A1, A2, B1 and B2)
The procedural review described for reactor coolant pressure boundary piping in paragraph 6 above also applies to the other safety related piping, as it is installed under the same control procedures.
8.
Containment (Structural - Steel Welding) - Observation of Work and Work Activities (Units Al and B1)
The inspector observed field welding activities associated with the steel containment shells for Units Al and B1 and the reactor pressure vessel (RPV) pedestal inside the containment for Unit Bl.
The activities were examined at various stages of weld completion. The applicable code for containment shell welding is ASME Section III, Subsection NE (74S74) as implemented through C. F. Braun Specification 300-13 (Rev.
7).
The ap-plicable code for pedestal welding is AWS D1.1 (Rev.
2-74) as implemented by C. F. Braan Specification 300-05-AB (Rev.
3).
The inspector observed tack welding for joint fitup and alignment for a.
the second to third course weld for the Unit Al containment shell to determine conformance with applicable specification and procedure requirements for performance of welding.
'u.
The inspector observed welding activities where welding was in progress on the containment vessel and the RPV pedestal for Unit Bl.
The activities were observed to determine conformance with specifica-tions and procedures in the areas of; weld identification, specified

Observation of weld material control included:
identification, segre-gation, oven temperatures, issue slips and control of unused material at issue stations and work areas.
d.
During observation of welding activities there did appear to be suf-ficient number of qualified personnel at the work site.
Within the areas examined, there were no items of noncompliance or deviations identified.
