Title	Threading Deviations on Steel Reinforcing Bar Supplied to Construction Projects
Event Description	This report was supplied for informational purposes. The threaded ends of some of the reinforcing bar supplied to the V.C. Summer Units 2 and 3 and the Vogtle Units 3 and 4 nuclear projects were found to have threads too long or too short, double threaded areas, voids in threads, or an incorrect thread profile. The results of evaluations of this condition as documented by Shaw Nuclear and conducted in accordance with the procedure for performing evaluations required by 10 CFR 21.21, have concluded that the deviations in the rebar would not create a substantial safety hazard, if they were to remain uncorrected. Therefore, it has been determined that these deviations are not reportable under the requirements of 10 CFR Part 21. This information is being provided for industry awareness of the occurrence of these types of deviations in reinforcing steel being provided as a basic component.
