2.

Site Tour The IE inspector toured several areas of the site to observe construction operations and general housekeeping.

Areas visited were Reactor Building i

No.1, MEAB No.1, MEAB No. 2 and several storage areas.

No violations were noted.

3.

Resumotion of ASMEsWeldino The IE inspector reviewed the B&R Ten Week Work Plan for resumption of ASME Code welding.

A tour was made of MEAB No.1, cubes 3E, 3F and 3J to visually inspect completed welds and to observe welding activities in progress.

Of the twenty-two piping welds completed, four were randomly selected for visual insoection.

The four welds, all in the component cooling system, were: CC 1425-P4 0008, CC 1428-FW 0005, CC 1428-FW 0008 and CC 1428-P4 0011.

The weld surfaces and adjacent base material were visually inspected for conditions such as undercut, excessive reinforce-ment, porosity, cracks, arc strikes, oroper contour and general weld appearance.

All four aDoeared to meet the Code reouirements.

The IE insoector witnessed part of the joint edge preparation repair oceration i

on weld CC 1435-FW 0006.

The weld preo area had been damaged during handling and required minor repairs prior to welding.

A review of documentation showed that work was being performed in accordance with MECP-4, Revision 11 and was being accomplished by a qualified welder.

Portions of the pre-weld fit-up and tack welding operations were observed on welds CC 1410-FW 0002 and CC 1435-FW 0004 The operations observed appeared to be in accordance with MECP-4, Revision 11 and Code require-ments.

During a tour of the fabrication shop, the IE inspector observed several small bore piping assemblies in various stages of completion, but no work was being accomplished on them at the time.

Control of tools and handling equioment for stainless steel material aapeared to be adequate in the fabrication shoo.

The IE inspector observed reinspection operations being cerformed on three circumferential welds that were part of the ECW system.

These joints were located in the material lay-down yard and were being liquid penetrant inspected as part of the ongoing re-examination and repair program.

The IE inspector did not determine the identification numbers of these joints, but observed the inspection techniques from a distance.

Observation from a distance was utilized, in this instance, to verify that procedural times and techniques were being complied with when the inspection personnel were unaware that they were being observed.

The remote observation indicated that the inspections were being conducted within the parameters established by inspection procedure ST-NDEP-4.1, Revision 9.

Qualification verification of the personnel cerforming the inspection was accomplished by having the area supervisor identify the inspectors and reviewing the cualification records of each.

This review indicated that all three inspectors were properly qualified in accordance with the provisions of SNT-TC-1A.

Status of Previously Identified Items The status of remaining coen items from IE Inspection Report No.

50-498/79-19; 50-499/79-19 and from the response to the resultant Order to Show Cause related to welding and NDE was reviered.

None of tne remaining open items have been completed and docuranted sucn that corrective action could be thoroughly verified.

No items were closed during this inspection.

5.

Exit Interview The IE inspector met with licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on January 9,1981.
