| Title | Part-21 Interim Report - Incorrect Pressurizer Support Loads For Ap1000 |
| Event Description | The deviation being evaluated is an identified inconsistency between the applied design loads for the AP1000 plant pressurizer support columns and embedments and the calculated actual loads. 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. The certified for construction drawings have been delivered to U.S. AP1000 plant new build customers, V.C. Summer Units 2 and 3, and A.W. Vogtle Units 3 and 4. |
