 AGENCY: Nuclear Regulatory Commission.
 ACTION: Regulatory basis; request for comment.
 SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is requesting comments on a regulatory basis to support a proposed rule that would amend the NRC's regulations for the licensing of new nuclear power reactors. The NRC's goals in amending these regulations would be to ensure consistency in new reactor licensing reviews, provide for an efficient new reactor licensing process, reduce the need for exemptions from existing regulations and license amendment requests, address other new reactor licensing issues deemed relevant by the NRC, and support the principles of good regulation, specifically openness, clarity, and reliability. The NRC plans to hold a public meeting to promote a full understanding of the rulemaking, discuss the regulatory basis, and facilitate public participation.
 DATES: Submit comments by April 14, 2021. Comments received after this date will be considered if it is practical to do so, but the NRC is only able to ensure consideration of comments received on or before this date.
 ADDRESSES: You may submit comments by any of the following methods; however, the NRC encourages electronic comment submission through the Federal Rulemaking Website: *Federal Rulemaking Website:*

However, the NRC will consider all comments received in the rulemaking process. II. Discussion The NRC is requesting comments on a regulatory basis to support a proposed rule that would amend the NRC's regulations for the licensing of new nuclear power reactors in parts 50 and 52 of title 10 of the 
                    *Code of Federal Regulations*
                     (10 CFR). The NRC's goals in amending these regulations would be to ensure consistency in new reactor licensing reviews, provide for an efficient new reactor licensing process, reduce the need for exemptions from existing regulations and license amendment requests, address other new reactor licensing issues deemed relevant by the NRC, and support the principles of good regulation, specifically openness, clarity, and reliability. These rule changes would apply to any power reactor application submitted to the NRC. For example, the scope of 
                    ( print page 7514)
                    impacted entities includes applicants for designs and facilities similar to large light water reactors operating today, new, large light water reactors (
                    *e.g.,*
                     similar to the KHNP APR-1400 and Westinghouse AP1000), small modular reactors (
                    *e.g.,*
                     similar to NuScale small modular reactor), and non-light water reactors (
                    *e.g.,*
                     high temperature gas reactor, fast reactors, and molten salt reactors) On January 15, 2019, the NRC held a Category 3 public meeting to obtain feedback from external stakeholders on the scope of the development of the regulatory basis for this proposed rule. Representatives of the commercial nuclear power industry presented 18 suggested changes at the meeting and submitted a list of 20 additional suggested changes. On September 20, 2019, the NRC met with individual members of the Regulatory Policies and Practices Subcommittee of the Advisory Committee on Reactor Safeguards (ACRS). The purpose of the meeting was to receive the ACRS members' observations on the implementation of the 10 CFR part 52 process based on their individual perspectives from their reviews of early site permit (ESP), design certification (DC), and combined license applications. On November 21, 2019, and April 29, 2020, the NRC held Category 3 public meetings with members of the public to provide updates on the agency's efforts since the January 15, 2019, public meeting. In these meetings, the NRC provided updates on progress including an overview of the scope of the regulatory basis. At both meetings, the NRC conducted question and answer sessions. Consistent with the NRC's rulemaking process, the NRC has prepared a regulatory basis to describe and document the results of assessments performed by the NRC in support of the proposed rule. This regulatory basis and the meeting summaries, including transcripts, are listed in the “Availability of Documents” section of this document. In the regulatory basis, the NRC concludes that there is sufficient basis to proceed with rulemaking to address the alignment of regulatory requirements associated with 10 CFR parts 50 and 52 and the incorporation of lessons learned from new reactor licensing reviews. However, through development of its regulatory basis, the NRC has determined that some areas within the scope previously discussed could be addressed using other regulatory alternatives. The Commission has not approved any specific recommendation in the regulatory basis at this time, and as such, any conclusions regarding the elements of the alignment of licensing processes and lessons learned from new reactor licensing process rulemaking are subject to change. III. Specific Requests for Comments The NRC is requesting comment on the regulatory basis titled “Alignment of Licensing Processes and Lessons Learned from New Reactor Licensing.” As you prepare your comments, consider the following general questions: 1. Is the NRC considering appropriate options for each regulatory area described in the regulatory basis? 2. Are there additional factors that the NRC should consider in each regulatory area? What are these factors? 3. Are there any additional options that the NRC should consider during development of the proposed rule? 4. Is there additional information concerning regulatory impacts that the NRC should include in its regulatory analysis for this rulemaking? Specific Regulatory Issues In addition to the general questions, the NRC has identified additional areas of consideration that could either be included in the scope of the alignment of licensing processes and lessons learned from new reactor licensing rulemaking or addressed through other actions. The NRC may include additional discussion of these issues in the proposed rule, and if included, will use any public comments received regarding these issues to inform the development of the proposed rule. The NRC requests that members of the public answer the following specific questions regarding these additional regulatory issues. Emergency Planning Significant Impediments to Development of Emergency Plans As required by § 52.17(b)(1), the site safety analysis report for an ESP application must include an evaluation of the physical characteristics of the proposed site, such as egress limitations from the area surrounding the site, that could pose a significant impediment to the development of emergency plans. 1. The NRC is considering revising the guidance in Regulatory Guide 4.7, “General Site Suitability Criteria for Nuclear Power Stations,” and NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition,” Chapter 13, “Conduct of Operations,” on how to meet the requirements of § 52.17(b)(1) and the siting criteria in 10 CFR part 100, “Reactor site criteria,” as it relates to siting and emergency planning for ESP reviews. The NRC is seeking comment on the appropriate distance within which to perform the analysis to demonstrate compliance with the siting criteria for identifying site characteristics that could pose significant impediments to the development of emergency plans. Please provide a basis for your response. Part 52 Process Standard Design Approvals Duration, Manufacturing License Renewal and Manufacturing License Expiration Date As described in § 52.147, standard design approvals (SDAs) are valid for 15 years from the date of issuance and may not be renewed. For manufacturing licenses (MLs), § 52.173 specifies that a license authorizing manufacture of nuclear power reactors is valid for no more than 15 years from the date of issuance. As part of this rulemaking, the NRC is considering the removal of the 15-year duration for DCs established in § 52.55 and DC renewal requirements in §§ 52.57, 52.59, and 52.61 and 10 CFR part 52 DC appendices. This would result in DCs that never expire and, therefore, do not need to be renewed every 15 years. The 2007 10 CFR part 52 final rule provided the term of an SDA to be for 15 years and the term of an ML to be for no less than 5, or no more than 15 years from the date of issuance. The Commission established the 15-year maximum term for SDAs and MLs to be consistent with the maximum term for a standard design certification. The 5-year minimum term was established by the Commission to encourage the use of an ML for the manufacture of more than one nuclear power reactor. 2. If the NRC eliminates the renewal requirements for DCs, should the NRC consider eliminating or changing duration requirements for MLs? 3. If the NRC eliminates the renewal requirements for DCs, should the NRC consider eliminating or changing the duration requirements for SDAs? Expired Design Certifications in 10 CFR Part 52 As part of the proposed rule, the NRC is considering the removal of the 15-year duration for DCs established in § 52.55 and DC renewal requirements in §§ 52.57, 52.59, and 52.61 and 10 CFR part 52 DC appendices. This would result in DCs that never expire and, therefore, do not need to be renewed every 15 years. However, there are presently two DCs contained in the appendices to 10 CFR part 52 (AP600 
                    ( print page 7515)
                    and System 80+) that have already expired. 4. Should the NRC remove expired DC rules from the appendices to 10 CFR part 52 in the proposed rule? Relationship to Advanced Reactors The current regulations in 10 CFR parts 50 and 52 were largely written during a period when the NRC was licensing light-water-reactors. Today, significant stakeholder interest exists in licensing new advanced non-light-water reactor designs. As such, in the proposed rule and in subsequent rulemakings addressing new licensing regulations for advanced reactors, the NRC wants to ensure that it considers stakeholder feedback on how regulatory changes would impact potential non-light-water reactor applicants. For example, the NRC recommends revising § 50.34(f) so that the TMI requirements in § 50.34(f) apply to new power reactor applications submitted under 10 CFR part 50, with the same exceptions given for 10 CFR part 52 applicants. Section 50.34(f) requires 10 CFR part 52 applicants to provide information necessary to demonstrate compliance with any “technically relevant” positions of the requirements in § 50.34(f)(1) through (3) with the exception of § 50.34(f)(1)(xii), (f)(2)(ix), and (f)(3)(v). The NRC is still considering whether and how these regulations would apply to non-light water reactors. 5. Please provide feedback on impacts of the TMI requirements on non-LWR applicants the NRC should consider in the scope of the proposed rule. Please provide the basis for your answer. IV. Cumulative Effects of Regulation The cumulative effects of regulation (CER) describes the challenges that licensees or other impacted entities (such as State agency partners) may face while implementing new regulatory positions, programs, and requirements (
                    *e.g.,*
                     rules, generic letters, backfits, inspections). The CER is an organizational effectiveness challenge that results from a licensee or impacted entity implementing a number of complex positions, programs, or requirements within a limited implementation period and with available resources (which may include limited available expertise to address a specific issue). The NRC has implemented CER enhancements to the rulemaking process to facilitate public involvement throughout the rulemaking process. Therefore, the NRC is specifically requesting comment on the cumulative effects that may result from this proposed rulemaking. In developing comments on the regulatory basis, consider the following questions: 1. In light of any current or projected CER challenges, what should be a reasonable effective date, compliance date, or submittal date(s) from the time the final rule is published to the actual implementation of any new proposed requirements, including changes to programs, procedures, or the facility? 2. If CER challenges currently exist or are expected, what should be done to address them? For example, if more time is required for implementation of the new requirements, what period of time is sufficient? 3. Do other regulatory actions (
                    *e.g.,*
                     orders, generic communications, license amendment requests, and inspection findings of a generic nature) by the NRC or other agencies influence the implementation of the potential proposed requirements? 4. Are there unintended consequences? Does the potential proposed action create conditions that would be contrary to the potential proposed action's purpose and objectives? If so, what are the consequences and how should they be addressed? 5. Please comment on NRC's costs and benefits estimate of the potential proposed action. This information will be used to support additional regulatory analysis by the NRC. V. Plain Writing The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal agencies to write documents in a clear, concise, well-organized manner. The NRC has written this document to be consistent with the Plain Writing Act as well as the Presidential Memorandum, “Plain Language in Government Writing,” published in the 
                    **Federal Register**
                     on June 10, 1998 (63 FR 31883). The NRC requests comment on this document with respect to the clarity and effectiveness of the language used. VI.
