Licensee Actions on Previous Inspection Findings a.
(Closed) Item of Noncompliance No. 416/78-09-01:
Failure to follow procedure for storage of safety-related piping.
This item involved safety-related piping being stored in contact with standing water and other miscellaneous materials. The licensee's response was received on August 10, 1978 and actions taken included; a complete survey of storage areas, reinstruction
.
.
RII Rpt. Nos. 50-416/78-17 and 50-417/78-17-2-of construction personnel and assignment of construction personnel to daily monitor storage areas. The NRC inspector observed storage areas during this inspection and found no unacceptable storage conditions.
b.
(Closed) Unresolved Item No. 416,417/78-12-01:
Three to one taper requirement for pipe to fitting / component welds. There was a question as to whether or not Bechtel QC procedures adequately identified the three to one transition requirement and whether Bechtel QC personnel were aware of this requirement.
The inspector reviewed procedure requirements related to this area and interviewed QC personnel regarding this requirement.
The inspector also verified that a test question concerning this requirement was included in the QC personnel training guide. The inspector considers this area to be satisfactory.
3.
Unresolved Items No unresolved items were identified during this inspection.
4.
Independent Inspection Effort a.
The inspector conducted a walk-through inspection of the containments and auxiliary building to observe construction progress and construction activities such as welding, material handling, housekeeping and storage.
b.
(Unit 1) The applicable code for pipe welding is the ASME Boiler and Pressure Vessel Code, 1974 Edition, plus addenda through the Summer of 1974.
The inspector observed two welds to determine if requirements were being met. Areas reviewed included (as applicable) weld identification, joint preparation, QC verification, use of specified weld procedure, physical appearance of weld, welder identification and qualification, use of specified pre-heat, and use and control of specified weld material. Specific welds observed were fitup of 3"x.216" butt weld No. 73 of ISO M1358E and second layer welding of 18"x.438" butt weld No. 40C2 of ISO M1348F.
No items of noncompliance or deviations were identified.
5.
Containmer.t (Structural Steel Welding) - Observation of Work and York Activities (Unit 2)
The applicable code for containment fabrication is the ASME Boiler and Pressure Vessel Code, 1971 Edition, plus addenda through the Summer of 1973. The inspector observed welding activities to determine if requirements were being met.
Specific areas reviewed I

.
RII Rpt. Nos. 50-416/78-17 and 50-417/78-17-3-included (as applicable); weld identification / location, joint preparation, use of specified weld procedure, use of specified weld material, QC verification, periodic welding burn-off rate checks, welder and inspector qualifications, and welding material issue and control. Welds observed were as follows:
Weld Description Stage of Completion Observed Dome Vertical Seam B6/B7 Fitup Complete Dome Vertical Seam B8/B9 Fitup Complete Dome Vertical Seam B9/B10 Fitup Complete Polar Crane Support 123F Fitup in Progress Polar Crane Support 125H Fitup in Progress Polar Crane Support 126J Fitup in Progress Dome Vertical Seam B2/B3 Welding in Progress Dome Vertical Seam B8/B9 Welding in Progress Dome Vertical Seam B9/B10 Welding in Progress Polar Crane Support 250A/1 Welding in Progress Polar Crane Support 258E/1 Welding in Progress Polar Crane Support 260F/1 Welding in Progress No items of noncompliance or deviations were identified.
6.
Containment (Structural Steel Welding) - Review of Quality Records (Unit 2)
The applicable code for containment welding is delineated in paragraph 5.
The inspector reviewed welding quality records to determine if requirements were being met.
Areas reviewed included inspector records, weld history records, NDE records, weld material issue records, welder qualification records and inspector qualification records. Records were reviewed for Dome Welds B1/B2, B1/1, B1/2, B2/1 and B2/2 and Polar Crane Support Welds 250A/1, 254C/1, 256D/1, 258E/1, 260F/1 and 266J/1.
The inspector also reviewed Bechtel QA audits No. F-C-10 and F-C-30; Bechtel Nonconformance Report Nos. 559 and 1176; and CBI Nonconformance Report Nos. 163, 164, 165, 166, 169, 171, 173 and 175 to determine if records were complete, legible, retrievable and properly closed l
out.
No items of noncompliance or deviations were identified.
7.

(Unit 1)
l The applicable code is delineated in paragraph 4.b.
The inspector l
observed handling activities of pipe spool numbers Q1E51-G532-2-11 l
and QIE12-G015-25-11 to determine if requirements were being met.
