As a result, certified for construction drawings have been delivered to customers of the AP 1000 plant new build projects with an incorrect pressurizer support column embedment design configuration. The planned changes to the embedments to correct this deviation for the pressurizer support columns will be reflected on revised certified for construction drawings but do not require changes to the current licensing basis.
