AGENCY:

Nuclear Regulatory Commission.

ACTION:

Draft regulatory basis; public meeting, and request for comment.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is requesting comment on a draft regulatory basis to support a rulemaking that would develop new emergency preparedness (EP) requirements for small modular reactors (SMRs) and other new technologies (ONTs), such as non-light-water reactors (non-LWRs) and medical isotope production facilities. The new EP regulations would be consequence-oriented, performance-based, and technology inclusive to the extent possible, and continue to provide reasonable assurance of adequate protection of public health and safety. The new EP regulations would be applicable to SMR and ONT facilities only. Large light-water reactors (LWRs), fuel cycle facilities, research and test reactors and other non-power, non-commercial, facilities are not in the scope of this rulemaking. The NRC plans to hold a public meeting to promote full understanding of the rulemaking and facilitate public participation.

II. Discussion

The NRC is requesting comments on a draft regulatory basis to support a rulemaking that would amend part 50 of title 10 of the Code of Federal Regulations (10 CFR), “Domestic Licensing of Production and Utilization Facilities,” and part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants,” by adopting new EP regulations for SMR and ONT licensees. The specific objectives of this rulemaking effort are to establish new EP requirements for SMR and ONT licensees that will recognize: (1) Distance to which planning for initiation of predetermined protective actions is warranted, (2) time-dependent Start Printed Page 17769characteristics of potential releases and exposures, and (3) isotopic characteristics of radioactive materials that can potentially be released to the environment.

The scope of the draft regulatory basis includes EP for new SMR and ONT facilities licensed under 10 CFR parts 50 and 52. Under current regulations for large LWR designs, the plume exposure pathway emergency planning zone (EPZ) size is about 10 miles (16 kilometers). However, SMRs and ONTs may have comparatively smaller reactor core size and also include passive design safety features, which result in potential accident releases and offsite radiation dose consequences that are smaller and may be delayed when compared to large LWRs. To account for this difference as compared to large LWRs, the NRC plans to develop a consequence-oriented, performance-based, and technology inclusive approach to EP for these SMR and ONT designs. With the proposed adoption of an approach for these designs where the plume exposure pathway EPZ size is scalable in proportion with potential accident consequences, the potential exists for this EPZ to be contained within the site boundary. The draft regulatory basis, in part, explains why the NRC believes the existing regulations should be updated, revised, and enhanced; presents alternatives to rulemaking; and discusses costs and other impacts of the potential changes.

III. Specific Requests for Comments

The NRC is seeking comments and supporting rationale from the public on the following questions:

Scope of Draft Regulatory Basis

  • Is the NRC considering an appropriate approach for each objective described in the draft regulatory basis?
  • Section 3 of the draft regulatory basis discusses the regulatory concerns the NRC expects to address through rulemaking. Section 4 presents the intended regulatory changes to address those regulatory concerns, and also discusses alternatives to rulemaking considered by the NRC. Are there other regulatory concerns within or related to the scope of the rulemaking efforts (see Section 4) that the NRC should consider? Are there other approaches or alternatives the NRC should consider to resolve those regulatory concerns?
  • Are there any other alternatives for EP for SMRs and ONTs to address beyond those discussed in the draft regulatory basis that the NRC should consider?
  • Are there other EP related issues that the NRC staff should consider in further developing this regulatory basis?
  • Is the scope of facilities to be included under the ONT umbrella (see Section 1.1) appropriate or can you suggest additions or deletions?

Performance-Based Approach

  • What are the benefits of a performance-based EP approach, other than those described in the draft regulatory basis?
  • Should the NRC continue research to establish performance-based criteria specific for SMRs and ONTs in the EP area? Examples of such research that has been performed are discussed in SECY-14-0038, “Performance-Based Framework for Nuclear Power Plant Emergency Preparedness Oversight,” (ADAMS Accession No. ML14259A589).
  • Is it appropriate to establish combined risk-informed and performance-based criteria, and can you suggest EP areas or methods where they could successfully be implemented?

Regulatory Impacts

  • Section 5 of the draft regulatory basis presents the NRC's initial consideration of costs and other impacts for a number of key aspects of the potential regulatory changes. This initial assessment is based on limited available data. The NRC is seeking additional data and input relative to expected and/or unintentional impacts from the desired regulatory changes. What would be the potential impacts to stakeholders, such as applicants, licensees, and the public, from implementing any of the desired regulatory changes described in this draft regulatory basis? We are also seeking comments on reasonable cost estimates for implementation of the EP for SMRs and ONTs regulations, including one-time startup cost and annual cost?
  • What would the cost be for 10 CFR part 52 licensees to be licensed under the proposed performance-based EP approach? What would be the cost difference between this new EP approach and the current EP approach in 10 CFR part 50?
  • What impacts, other than cost, would result from the rulemaking action under consideration?

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, Tribal and local governments) may face while implementing new regulatory positions, programs, and requirements (e.g., rules, generic letters, backfits, inspections). The CER is an organizational 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 comments on the cumulative effects that may result from this proposed rulemaking. In developing comments on the draft regulatory basis, consider and provide comments on 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 proposed requirements, including changes to programs, procedures, and 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 subsequent implementation of the new requirements, what period of time is sufficient?

3. Do other (NRC or other agency) regulatory actions (e.g., orders, generic communications, license amendment requests, and inspection findings of a generic nature) influence the subsequent implementation of the proposed rule's requirements?

4. Are there unintended consequences? Does the draft regulatory basis create conditions that would be contrary to the draft regulatory basis' purpose and objectives? If so, what are the unintended consequences, and how should they be addressed?

V. Availability of Documents

The NRC may post documents related to this rulemaking activity to the Federal rulemaking Web site at http://www.regulations.gov under Docket ID: NRC-2015-0225.
