The Nuclear Regulatory Commission updated and renewed Westinghouse’s AP1000 reactor design certification on October 14. The certification, valid through 2066, incorporates experience from Vogtle Units 3 and 4 and gives future applicants a standardized AP1000 design that the NRC has evaluated. The NRC said the action does not authorize any reactor site, construction project or operating facility.
What it means
The updated AP1000 design incorporates lessons from the construction and startup of Vogtle Units 3 and 4, during which the NRC reviewed and approved nearly 200 license amendments. Future applicants can cite the updated design when proposing changes that the agency has already evaluated.
The renewed certification is intended to limit repeated regulatory reviews and lower licensing costs. Applicants must still obtain NRC approval for site-specific environmental, safety and security matters.
