What the agency says
The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations to renew the AP1000 design certification and incorporate Revision 20 of the AP1000 design control document. The purpose of this rulemaking action is to update the AP1000 design to be consistent with changes made to the design during the licensing, construction, and operation of Vogtle Electric Generating Plant, Units 3 and 4. This rulemaking incorporates AP1000 design control document Revision 20, which includes updates made to the AP1000 design to represent a current, construction-validated design. The NRC is also issuing an environmental assessment supporting this rule.
