Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (STN 50-48Z/78-10):

Failure to Follow Procedures.

IE Inspection Report No. STN 50-482/78-10 stated that Chicago Bridge and Iron (CB&I) welding personnel were -tack welding stiffeners to the contain-ment liner dome plating without removing scale and rust. This was in violation of GWPS-SMA 74-3750/59, Revision 1.

It was determined by CB&I that a one day reassign =ent of the pre-weld cleaning man allowed this to happen.

Immediate action by CB&I was to remove 20% of the questionable tack welds by " ski =-cutting" using the air-are gouging method and an inspection with magnetic particles. No subsurface defects were found.

The weld areas were cleaned of rust and scale prior to final welding.

CB&I conducted a training session for supervisors and instructed them to provide more coverage to prevent recurrence. This matter is considered resolved.

(Closed) Unresolved Item (STN 50-482/78-12):

Inadequate Procedures.

IE Inspection Report No. STN 50-482/78-12 stated that RECO Procedure ES-106N for inspection of welds did not meet the requirements of ASME B&PV Code Section III, 1974 edition through Winter 1975 Addenda in that there was no provision to perform spot radiograph of the work produced by each individual welder. Revision 2 of this procedure dated November 13, 1978, has been issued and does adequately state that radiography will be per-formed on welds made to each procedure used and at least one sample of each welder's work. Based on this action, this item is considered resolved.

(Closed) Infraction (STN 50-482/78-12):

Failure to Control Special Processes.

IE Inspection Report STN 50-482/78-12 stated that RECO welding procedures did not reflect the pre-weld cleaning requirements of ASMI B&PV Cede, 1974 edition through Winter 1975 Addenda.

Revision 2 of Procedure I1/MMA-1, dated April 18, 1978, added a supplementary page which adequately defines the pre-weld cleaning necessary and cc:-

d ntien prevention to be observed during welding. Based on this acrien, this iten is considered resolved.
