AP1000 Design Certification Amendment

The U.S. Nuclear Regulatory Commission (NRC or Commission) is amending its regulations to certify an amendment to the AP1000 standard plant design. The amendment replaces the combined license (COL) information items and design acceptance criteria (DAC) with specific design information, addresses the effects of the impact of a large commercial aircraft, incorporates design improvements, and increases standardization of the design. This action is necessary so that applicants or licensees intending to construct and operate an AP1000 design may do so by referencing this regulation (AP1000 design certification rule (DCR)), and need not demonstrate in their applications the safety of the certified design as amended. The applicant for this amendment to the AP1000 design is Westinghouse Electric Company, LLC (Westinghouse).
