Response to Notice of Violation Reference Notice of Violation - E. H. Johnson letter to W. J. Cahill dated August 2, i 1985.

Refer to Docket 50-458/85-29.

, Response to 85-29-01 " Failure to Assure Conformance of Safety-Related 1 Structural Steel Welds with Requirements" Reason for the Violation The cause of this deficiency appeared to be the inability of Field Quality

, Control (FQC) inspectors to consistently apply adequate inspection tech-niques during structural steel visual weld acceptance.

Corrective Steps Which Have Been Taken and Results Achieved

]

1 Additional samples were taken of welds previously accepted by the eight

! inspectors identified during the initial audit. One of these eight inspec-tors only inspected two additional Category I welds and these inspection

, reports were for inspection of erection seat welds, defined as tanporary.

Therefore, no additional reinspection was performed for that inspector. A total of 42 connections representing 75 welds were reinspected for the l remaining seven inspectors. Results of the reinspection are documented on Type "C" Inspection Report S-5620033. Additionally, earlier quality veri-fication inspections were performed in association with GSU DR-43 and DR-78. Type "C" Inspection Reports S-52620000 and S-2620012 document veri-

fication of weld inspecticns performed by six inspectors, representing 107 welds. Inspection Report S-3201307, S-3201319, S-3201320 and S-3201381 docunent verification of weld inspection by seven inspectors, representing 70 welds. These quality verification inspection results, which cover a four-year period of structural welding inspection at River Bend Station, establishes a confidence factor that structural welding inspections were performed in accordance with the existing criteria.

N&D 11756 was dispositioned " Accept-As-Is" for the welding discontinuities l identified during the initial NRC audit. Due to the fact that the inspec-tors involved are no longer anployed at River Bend Station, specific cor-rective action for those inspectors is not applicable, i
