DETAILS 1.

Persons Contacted Nebraska Public Fower District (NPPD)

• L. C. Lessor, Station Superintendent

P. V. Thomason, Assistant to the Station Superintendent V. Wolstenholm, QA Supervisor Chicago Bridge and Iron (CB&I)

R. Gorder, Project Manager F. Lusch, Welding /QA Superintendent W. Wagner, Corporate Welding /QA Assistant Manager Hartford Steam Boiler Inspection and Insurance Company F. Brusseau, Authorized Nuclear Inspector The NRC inspector also contacted other licensee and contractor personnel during the inspection.

• Denotes presence at the exit interview.

2.

Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (8114-04):

This item was unresolved pending review of the CB&I welding procedure qualification test report to dc vmine if a change in welding technique had been authorized.

The NRC inspector reviewed the welding procedure qualification test report, Production Test Assembly (PTA), Revision 1.

Since the PTA report is silent regarding any deviations from the contract Technical Specification requirements, the change in welding techr.ique from that required in the contract Technical Specification was not authorized.

This item is therefore upgraded to a violation.

3.

Mark I Torus Modifications a.

Review of Procedures The NRC inspector reviewed three CB&I welding procedure specifi-cations (WPSs) and supporting procedure qualification reports (PQRs)

with no discrepancies noted from the requirements of NPPD Contract I

l No. 80-28, including ASME B&PV Code, Sections III and IX, 1977 l

Edition and Summer 1977 Addendum.

The WPSs and PQRs reviewed were:

Welding (ASME Section III NE)"

PQR 4941, Revision 0, " Qualification for WPS-E7018 #2" WPS-E705-2/E7018/05240, Revision 0, " Procedure for Gas Tungsten-Arc Welding And Shielded Metal-Arc Welding (ASME Section III NC)"

PQR 4937, Revision 0, " Qualification for WPS-E705-2/E7018" PQR 4938, Revision 0, " Qualification for WPS-E70S-2/E7018" b.

Observation of Work The NRC inspector observed activities related to the torus modifi-cations, specified in NPPD Contract No. 8-28, which included: welding of a vacuum breaker reinforcement plate, piece 12BL on Sketch SK-119; welding of a downcomer brace, piece Mark 44-4 to 44BR on Drawing 43; welding of the high pressure coolant injection (HPCI) turbine exhaust sparger pipe, weld CF on Drawing R3; final visual inspection of HPCI turbine exhaust sparger pipe, welds CA, CB, and CC on Drawing R3; and radiographic examination of sparger pipe weld CA.

In the areas of weld and inspection documentation, weld procedure compliance, welder qualification, electrode control, inspector certi-fication; no discrepancies were noted from the requirements of the following documents:

NPPD Contract No. 80-28, " Mark I Torus Modification" CB&I Nuclear Quality Assurance Manual CB&I Procedure APIN, " Alteration Procedure for Torus Modifications" CB&I Procedure WPS-E7018 #1, " Welding of Carbon Steel Supports" CB&I Procedure WPS-E705-2/E7018, " Welding of Carbon Steel Pipe" CB&I Procedure VT5X, " Visual Inspecticti" CB&I Procedure RT9X, " Radiographic Examination cf Pipe Welds" No violations or deviations were identified.
