Power Company re;5orted an item related to welds in vendor-fabricated main steam line (MSL) pipe whip restraints. .

A 100% visual re-inspection of all welds in the fabricated MSL pipe whip restraints is underway to detennine whether they meet the requirements of the American Welding Society Code (AWS D.l.1-1977). Thus far 102 units have been re-inspected, including 51 units at the site and 51 at an off site painting shop. The re-inspection has found that 72 of the units con-tain code rejectable welds.
