2.
Plant Tour The inspector observed work activities in progress, completed work, and construction status in several areas.
Work items were examined for obvious defects and for noncompliance with regulatory requirements and licensee commitments.
Specific activities observed by the inspector included soap bubble test of containment liner pad leak test channel, 1666 193
.
.
fit up of containment dome liner, repairs to reactor coolant loop piping and welding activities on safety related piping.
No items of noncompliance were identified.
3.
Protective Coating of Containment Liner The inspector observed provisions for spraying a protective coating on the containment liner, discussed inspection requirements and performance with the QC inspector assigned to this work and reviewed calibration records and control of instruments used during inspections of this work.
The inspector observed that the work area was protected, enclosed and heated to maintain the proper environmental control for surface preparations and application of the protective coating.
No items of noncompliance were identified.
4.
Vendor Documentation - Containment Liner and Embedments The inspector audited vendor documentation; including material test reports, certificates of compliance, vendor manufacturing and inspection records and vendor surveillance inspection reports for the following items:
a.
Containment liner plates Assembly 34 Bl and 34 Cl, Group CC-1 b.
Containment embedments PC Marks 1843/1-1848/l and 1854/1-2; Gouveneur Iron Works c.
Structural shapes Mark No. 1038-M1 M2 and M3; PBI Industries These documents were audited for conformance to the requirements of specifications 2 BVS-65, 2 BVS-416 and 2 BVS-412, respectively.
No items of noncompliance were identified.
5.
Containment Liner and Structural Steel Erection Records The inspector interviewed the licensees structural QC inspector and reviewed Inspection Reports S 2100 concerning erection of columns and platform steel at elevation 717'-0" and S-2083 for welding of clip angles at elevaton 717'-0".
These records were reviewed for conformance to the requirements of:
a.
Specification 2 BVS-412, Revision 1, " Structural Steel" b.
Procedure IP-6.3, dated October 30, 1978, " Structural Steel Erection and Bolting" 1666 194
.
The inspector also examined receiving reports and installation records for the first, second and third rir.:s of the containment liner including records of MT and UT examinations and vacuum box tests.
These records were examined for conformance to the requirements of Specification 2 BUS-065, Addendum No. 4, " Reactor Containment Liner and Mat Embedments".
No items of noncompliance were identified.
6.
Qualifications and Training of QC Personnel The inspector reviewed personnel records of selected QC inspectors performing surveillance inspections of installation of the containment liner by PDM and inspection of structural steel erection, welding and application of protective coating on the containment liner.
The records, including education, experience, training, physical examinations and certificates of qualifications, were reviewed for conformance to the requirements of Section 17 of the PSAR.
No items of noncompliance were identified.
7.
Fabricated Tanks The inspector had previously informed the licensee that defects had been identified at another site in tanks supplied by Industrial Piping and Supply Company (IP&S) and had requested that the licensee determine whether that company had supplied any tanks for this project.
Review by S&W had determined that 1P&S had not supplied any tanks for this project.
This information was confirmed by memo 2 BVM-1065 from S&W to DLC.
The inspector had no further questions concerning this matter.
8.
Safety Related Piping-Welding Controls The inspector audited two weld procedures technique sheets and associated procedure qualification tests for compliance with the ASME Boiler and Pressure Vessel Code Section IX, 1971 Edition, including the Winter 1972 Addenda.
The procedures audited were:
Schneider Welding Procedure SPBV115M, Revision 1 and associated procedure qualification tests 760820 and 759456, and 115H, Revision 1 and associated procedure qualification tests 761357.
The following items were reviewed:
a.
To determina whether the weld procedures selected including all essential variables, supplementary essential variables and non-essential variables are in compliance with Section IX of the ASME B&PV Code.
b.
