- Attended exit interview 2.
Exit Interview The inspection scope and findings were summarized on October 21, 1980 with those persons indicated in Paragraph I above. The inspector reminded the licensee of the ultimate responsibility for the quality of installed equipment in the plant regardless of how the equipment is furnished. Their recently identified problems with unsatisfactory welds on contractor fur-niched equipment should reinforce that area of concern.
3.
Licensee Action on Previous Inspection Findings (Closed) Infraction 566, 567/80-03-01, Failure to Establish Adequate Measures to Control Radiography.
The inspector reviewed the licensees second revised response to this item, dated October 3, 1980, which addresses the final corrective actions for the CB&I radiography problems.
This response discussed the reasons for the film darkening problem as well as the the corrective actions taken to preclude recurrence. The inspector reviewed six of the seven additional weld increments which required reshooting for penetrameter placement (the seventh could not be reshot because it was cut out to insert a penetration). Based on the review of the licensees letter, the radiographs, and procedure change implementation for placement of penetrameters and processing controls. This item is closed.

Independent Inspection Effort The inspector conducted a general inspection of the construction site. This inspection included the following areas and activities:
Reactor Building and Waste Processing Building - Observed handling of a.
skid mounted piping assembly for the waste processing building and protection of installed equipment in the reactor building areas.
Inspection of the electrode issue station in the reactor building area.
b.
Warehouse - Inspected Class A, B pd C storage areas; observed receipt inspection and handling of pipe fittings in the receiving area; inspected storage of major components and piping for Unit 1.
Fabrication Shops - Observed welding of stainless steel piping sub-c.
assemblies for building drainage systems in pipe shop.
Observed welding and inspection of reactor building cable tray cupports in the fabrication shop; inspected the electrode issue station in the fab-rication shop area.
During these inspections the inspector discussed job requirements, quality control requirements, and amounts of supervisor's assistance with various craft personnel. The craft personnel interviewed appeared to be knowledge-able about requirements and felt that their foreman would help them to understand anything that was a problem.
There were no items of noncompliance or deviat-ions in this area of the inspection.
