2.
Site Tour The IE inspector toured the Units 1 and 2 Reactor Buildings and Auxiliary Building to observe construction activities in progress and to inspect housekeeping.
No items of noncompliance or deviations were identified.
3.
Reactor Coolant Pressure Boundary Piping - Unit 1 a.
Observation of Work The IE inspector observed the fitup, root welding and fill welding of field weld FW-2 on Drawing RC-1-RB-020, Revision 2 for the Reactor Coolant system pipe line 4"-RC-1-075-2501R-1 for compliance with Welding Ptocedure Specification (WPS) 88021, Revision 6/ICN 3 and Construction Procedure CP-CPM 6.9, Revision 0.
The root and fill welding of field weld FW-14 on Drawing RC-1-RB-008, Revision 2 for Reactor Coolant system pipe line 2"-RC-1-053-2501R-1 was observed by the IE inspection for compliance with WPS 88023, Revision 9, ICN 3 and CP-CPM 6.9.
The IE inspector observed the fitup inspection by a B&R Quality Control (QC) inspector of a socket weld, identified FW-4, in the Reactor Coolant system pipe line 1"-RC-1-050-2501R-1 on Drawing RC-1-RB-032, Revision 2.
The QC inspector rejected the fitup for not complying with the end gap measurement requirements of CP-CPM 6.9, Revision 0.

The hydrostatic testing of FW1-1 and Spool IQ2 on Drawing RC-1-RB-040, Revision 6'for the Reactor Coolant system pipe line 3/4"-RC-1-081-2501R-2 was observed by the IE inspector to be in progress and reported as Test No. 1-RC-079-5505-HO.
The Hydrostatic Test Report was reviewed for compliance with CP-CPM 6.9I, Revision 0.
In the areas inspected, no discrepancies from the requirements of the Welding Procedure Specification, the construction procedure, or the
>
No items of noncompliance or deviations were identified.
b.
Review of Records The IE inspector reviewed the receiving inspection records and material certification reports for the following welding filler materials for compliance with CP-CPM 6.9B-1, Revision 0 for procurement requirements and CP-QAP-8.1, Revision 0 for QC receiving inspection.
Heat Number Receiving Inspection 4282R308L RIR 11595 746100 RIR 8386 463638 RIR 9625 No items of noncompliance or deviations were identified.
4.
Safety-Related Piping - Units 1 and 2 a.
Observation of Work The IE inspector observed a condition in Unit I where rusting had occurred on two stainless steel socket welds and adjacent pipe material which is indicative of contamination of the material surfaces with carbon steel material.
The contamination-could have occurred from using a wire brush not specified in CP CPM 6.9 for use on stain-less steel materials.
The condition of the two socket welds in the Safety Injection system, FW-4 and FW-5 on Drawing SI-1-RB-051, was discussed with BSR Welding Engineering and QC personnel who initiated corrective action to remove the contamination and to reinspect the welds. As a preventative measure, B&R Welding Engineering informed the IE inspeceor that the craft would be reinstructed ou control and proper i=* of wire brushes as delineated in CP-CPM 6.9.
Approxi-mately thirty other stainless steel welds were inspected which did not exhibit the rust / contamination condition; therefore, this is considered an isolated case that does not warrant further action.

Two Main Steam system pipe penetration to sleeve field welds in Unit 2 were observed during _ root welding of FW-1 and fill welding of FW-3; both field welds are identified on Drawing PN-2-503-001-0.
Welding appeared to be consistent with requirements of WPS 11013, Revision 5 for FW-1 and WPS 99027, Revision 2 for FW-3.
No items of noncompliance or deviations were identified.
b.
Review of Records The IE inspector reviewed the receiving inspection records and material certification reports for the following welding filler materials for compliance with CP-CPM 6.9B-1, Revision 0 for procurement require-ments and CP-QAP-8.1, Revisica O for QC receiving inspection.
Heat Number Receiving Inspection 065305 RIR 10395 4250B131 RIR 11039 No items of noncompliance or deviations were identified.
5.
Exit Interview The IE inspector met with a licensee representative (denoted in paragraph 1)
and R. G. Taylor (NRC Resident Reactor Inspector) on May 16, 1980, and summarized the purpose, scope and findings of the inspection.
