Review of Method of Weld Fitup Inspection (Units 1, 2 and 3)
The applicable code for installation of safety related piping at Browns Ferry is the Power Piping Code, B31.1.
Concerns were recently expressed to NRC:RII regarding the use of welders in lieu of QC inspectors to perform fitup inspection of safety related welds when the applicable code is the Power Piping Code, B31.1.
The inspector discussed performance of fitup
e l
-2" inspection at Browns Ferry with maintenance and outage management personnel.
In both cases it was indicated that QA/QC personnel are used for fitup inspections of safety related welds. It should be noted that site maintenance personnel seldom perform safety related welding and QA/QC welding controls of the outage personnel were recently reviewed by NRC (See NRC:RII Report Nos. 50-259, 260, 296/79-29).
No items of noncompliance or deviations were identified.
