Title	Inadequate Welds Affecting Structural Capacity of Embed Plates
Event Description	MOX [Mixed Oxide] Services has determined that the fillet welds connecting the ledger angle to the embed plate did not comply with the minimum size required by AWS D1.1-98 and the design requirements. The embed plates containing defects were supplied to MOX Services as a basic component by Specialty Maintenance and Construction, Inc. (SMCI) Division of MetalTek International. The undersize fillet welds connecting the ledger angle to the embed plates were determined to be inadequate. Inadequate welds would adversely affect the load bearing and structural capacity of these components. CB&I Part 21 interim report, dated January 20, 2015, indicates that Vogtle Units 3 and 4 have been supplied with basic components by SMCI. These weld defects related to the SMCI embed plates were initially identified by nonconformance report on February 24, 2015.
