The inspector conducted general inspections of site work and work activities and observed equipment protection / storage and housekeeping in the auxiliary building, containment buildings, pipe fabrication shop and storage areas.

b.

The inspector reviewed numerous Nonconforming item Reports (NCI's) to determine if nonconforming conditions were adequately described, dispositioned and evaluated in accordance with NRC and licensee procedure requirements.

c.

The inspector reviewed QA surveillance reports to determine if specific construction areas were being adequately reviewed and to determine if adequate followup actions were being performed.

Licensee Identified Items (50.55(e))

a.

(Closed) (413, 414/81-17-05): Inadequate evaluation of materials. The item concerned the fact that the licer.see had not evaluated past material problems for reportability.to NRC. The licensee has determined that materials were repaired or scrapped as appropriate.

These actions are considered satisfactory.

b.

(Closed) (413,414/81-17-06): Inadequate evaluation of materials.

This item is similar to the item above and actions concerning this item were

,.

Safety-Related Piping (Welding)-Observation of Work and Work Activities a.

The applicable code for installation of safety-related piping is the ASME Boiler and Pressure Vessel Code,Section III,1974 Edition plus addenda through summer 1975.

The inspector observed in-process welds at various stages of completion and reviewed records for conformance to code and procedure requirements in the areas of documentation of pertinent information and QC signoffs via a weld traveler, availability of pertinent instructions, use of appropriate qualified welding procedure, provisions for weld repair, certification of filler material, control of welding parameters, verification of welder

,

qualification, use of specified shielding and purge gas, condition of welding equipment, provisions for voltage and amperage cnecks, verification of proper fitup, control of preheat and interpass temperature, conditon of weld and base metal surfaces, and verification that appropriate inspections were being performed. The following welds were observed:

Safety-Related Piping - Observation of Work and Work Activities The applicable code is delineated in paragraph 8.

The inspector observed handling and protection of piping for fabrication of the welds listed in paragraph 8 for conformance to procedure and code requirements in the areas of control of tools for grinding, brushing and filing; use of appropriate handling and rigging equipnent; control of cleanliness; and control of cold spring where applicable.

No violations or deviations were identified.

11.

Reactor Coolant Pressure Boundary Piping - Observation of Work and Work Activities a.

The applicable code is delineated in paragraph 8.- The inspector observed handling and protection of piping for fabrication of the welds listed in paragraph 9 for conformance to procedure and code require-ments in the areas of control of tools for grinding, brushing and filing; use of appropriate handling and _ rigging equipment; control of cleanliness; and control of cold spring where applicable.

In addition, the inspector observed initial walkdown inspections of piping in

'

accordance with isometric drawings CN-1491-NIO84, Rev.12 and CN-1491-NIO85, Rev.10.

b.

During the walkdown inspection on August 7,1981 it appeared that the measuring techniques being used could, in certain instances, result in significant errors on the order of several inches.

Essentially, steel tapes and an' angle finder were being used.

The inspector noted that the installation inspection toleranca is plus or minus 1 inch. The inspector informed the licensee that this would be an unresolved item until a full evaluation was made to determine if significant errors have been made and/or if inspection techniques need to be improved (413,414/81-19-01, Control of measurement accuracy during piping-system installation inspections).
