The Nuclear Regulatory Commission (NRC or Commission) is amending its regulations to certify the System 80+ design. The NRC is adding a new provision to its regulations that approves the System 80+ design by rulemaking. This action is necessary so that applicants for a combined license that intend to construct and operate the System 80+ design may do so by appropriately referencing this regulation. The applicant for certification of the System 80+ design was Combustion Engineering, Inc. (ABB-CE).
