NUCLEAR REGULATORY COMMISSION

10 CFR Part 50

[NRC-2020-0071]
RIN 3150-AL35


Cost Expenditure Criteria for Research and Development 
Utilization Facilities

AGENCY: Nuclear Regulatory Commission.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is amending its 
regulations to address the financial criteria used to determine whether 
a utilization facility that is useful in the conduct of research and 
development activities is licensed as a commercial facility under 
section 103, ``Commercial Licenses,'' of the Atomic Energy Act of 1954, 
as amended, or as a research and development facility under section 
104, ``Medical Therapy and Research and Development.'' This rulemaking 
revises the NRC's regulations to be consistent with the Nuclear Energy 
Innovation and Modernization Act, enacted on January 14, 2019, and the 
Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy 
Act of 2024, enacted on July 9, 2024.

DATES: This final rule is effective on April 24, 2026.

SUPPLEMENTARY INFORMATION: This rulemaking is separate from NRC's 
comprehensive review and reform of its regulations in accordance with 
Executive Order (E.O.) 14300, ``Ordering the Reform of the Nuclear 
Regulatory Commission'' (90 FR 22587; May 29, 2025). The rulemakings 
associated with that effort will comprehensively reexamine NRC 
requirements. The NRC is moving forward with this final rule at this 
time because it was in progress before the issuance of E.O. 14300 and 
is a deregulatory action of high interest to NRC stakeholders.

I. Background

    The NRC's regulations in part 50, ``Domestic Licensing of 
Production and Utilization Facilities,'' of title 10 of the Code of 
Federal Regulations (10 CFR), provide requirements and procedures for 
licensing of production and utilization facilities. For production or 
utilization facilities used for commercial or industrial purposes, the 
NRC issues licenses under section 103, ``Commercial Licenses,'' of the 
Atomic Energy Act of 1954, as amended (AEA), and 10 CFR 50.22, ``Class 
103 licenses; for commercial and industrial facilities.'' Section 50.22 
currently provides that a production or utilization facility is deemed 
to be for industrial or commercial purposes if it is to be used so that 
more than 50 percent of the annual cost of owning and operating the 
facility is devoted to the production of materials, products, or energy 
for sale or commercial distribution, or to the sale of services, other 
than research and development or education or training. Commercial and 
industrial facilities are subject to additional licensing requirements 
beyond those for research and development facilities, such as review by 
the Advisory Committee on Reactor Safeguards, mandatory hearings, and 
fixed license terms not to exceed 40 years.
    For production or utilization facilities useful in the conduct of 
research and development, the NRC issues licenses under paragraph c of 
section 104, ``Medical Therapy and Research and Development,'' of the 
AEA and paragraph (c) of Sec.  50.21, ``Class 104 licenses; for medical 
therapy and research and development facilities.'' Under the current 
regulations, a production or utilization facility can be licensed as a 
research and development facility only if the licensee devotes no more 
than 50 percent of the annual cost of owning and operating the facility 
to the commercial activities described in Sec.  50.22.
    Amendments made to the AEA by the Nuclear Energy Innovation and 
Modernization Act (NEIMA), enacted on January 14, 2019 (Pub. L. 115-
439; 132 Stat. 5565), and the Accelerating Deployment of Versatile, 
Advanced Nuclear for Clean Energy Act of 2024

[[Page 21938]]

(ADVANCE Act), enacted on July 9, 2024 (Pub. L. 118-67, div. B, 138 
Stat. 1448), changed the framework for determining whether a 
utilization facility would be licensed by the NRC under section 103 or 
section 104c. of the AEA. This final rule revises the NRC's regulations 
to be consistent with the AEA, as amended by NEIMA and the ADVANCE Act.

II. Discussion

    The NRC is amending its regulations in Sec. Sec.  50.21(c) and 
50.22 to conform with changes made to section 104c. of the AEA that 
apply to the issuance of class 104c licenses for utilization 
facilities. This final rule does not change the cost expenditure 
criterion in Sec.  50.22 for production facilities.
    Section 106, ``Encouraging Private Investment in Research and Test 
Reactors,'' of NEIMA amended section 104c. of the AEA in two ways. 
First, NEIMA removed language in section 104c. of the AEA that provided 
that the facility is not of the type specified in section 104b. of the 
AEA. Second, NEIMA added language to the end of section 104c. of the 
AEA providing that the NRC may issue a license for a research and 
development utilization facility under section 104c. of the AEA if two 
conditions were satisfied: (1) not more than 75 percent of the annual 
costs of owning and operating the facility are recovered through sales 
of nonenergy services, energy, or both (not counting sales of research 
and development or education and training); and (2) not more than 50 
percent of the annual costs are recovered through sales of energy. This 
amendment to the AEA changed the framework under which the NRC 
determines whether a utilization facility that is useful in the conduct 
of research and development would be licensed under section 103 or 
section 104c. of the AEA. Before the enactment of NEIMA, the AEA did 
not specify the criteria to use when determining whether to issue a 
class 103 or class 104c license for a facility--the criterion appeared 
only in Sec.  50.22. Section 601 of the ADVANCE Act amended section 
104c. of the AEA to remove the language that NEIMA added and to replace 
it with new language focused on the percentage of the annual cost of 
owning and operating a facility that is devoted to commercial 
activities, similar to the criterion currently included in Sec.  50.22. 
The new language added by the ADVANCE Act specifies that the NRC may 
issue a license for a research and development utilization facility 
under section 104c. of the AEA if two conditions are satisfied: (1) not 
more than 75 percent of the annual costs of owning and operating the 
facility are devoted to the sale of nonenergy services, energy, or a 
combination of these activities (not counting sales of research and 
development or education and training); and (2) not more than 50 
percent of the annual costs of owning and operating the facility are 
devoted to the sale of energy. The ADVANCE Act thus increases the 
percentage of annual costs of owning and operating the facility that 
may be devoted to commercial activities beyond the percentage currently 
included in the NRC's regulations in Sec.  50.22 for determining 
whether a utilization facility useful in the conduct of research and 
development activities may be licensed under section 104c. of the AEA. 
The changes to Sec.  50.22 made by this final rule align the regulation 
with the changes to the AEA made by the ADVANCE Act and do not 
establish new or different classes of production or utilization 
facilities that are licensed under section 103 of the AEA and Sec.  
50.22. The term ``class 103 license'' continues to be used for 
production or utilization facilities that are licensed under section 
103 of the AEA and Sec.  50.22.

III. Section-by-Section Analysis

    The following paragraphs describe the changes made by this final 
rule.

Section 50.21 Class 104 licenses; for medical therapy and research and 
development facilities

    This final rule amends paragraph (c) to implement the amendment 
made by NEIMA to remove language in section 104c. of the AEA that 
provided that the facility is not of the type specified in section 
104b. of the AEA. Consistent with this statutory change, this final 
rule amends paragraph (c) in Sec.  50.21 to remove the language that 
specifies that the facility is not of the type specified in paragraph 
(b) in Sec.  50.21. Paragraph (c) in Sec.  50.21 continues to specify 
that the facility is not of the type specified in Sec.  50.22.

Section 50.22 Class 103 licenses; for commercial and industrial 
facilities

    This final rule amends Sec.  50.22 by reorganizing the section to 
add paragraphs (a), (b), and (c) for the criteria for issuing class 103 
licenses. Paragraph (a) retains the current list of activities covered 
by a class 103 license. Paragraph (b) retains the current cost 
expenditure criterion for when a production facility that is useful in 
the conduct of research and development shall be licensed as an 
industrial or commercial facility. Paragraph (c) contains the amended 
cost expenditure criteria for when a utilization facility that is 
useful in the conduct of research and development shall be licensed as 
an industrial or commercial facility.

IV. Regulatory Flexibility Certification

    Under the Regulatory Flexibility Act (5 U.S.C. 605(b)), the NRC 
certifies that this rule does not have a significant economic impact on 
a substantial number of small entities. This final rule affects the 
licensing and operation of utilization facilities that are useful in 
the conduct of research and development purposes, which are 
predominately non-power utilization facilities. In general, the 
companies, universities, and government agencies that own these 
facilities do not fall within the scope of the definition of ``small 
entities'' set forth in the Regulatory Flexibility Act or the size 
standards established by the NRC (Sec.  2.810, ``NRC size standards'').

V. Regulatory Analysis

    The NRC has prepared a final regulatory analysis for this 
regulation. The analysis examines the costs and benefits of the 
rulemaking alternative. The NRC estimates that the final rule results 
in savings of approximately $44,000 (7 percent net present value in 
2025 dollars to licensees and the NRC). To conduct this analysis, the 
NRC assumed that under the regulatory baseline alternative, should the 
NRC not engage in rulemaking, all 32 existing class 104c licensees 
would submit license exemption requests in order to continue to abide 
by the conditions of their licenses should they choose to increase the 
percentage of the annual costs of owning and operating the facility 
devoted to commercial activity up to the percentage allowed under the 
AEA. The NRC did not analyze any additional alternatives because there 
is no other way to remove the inconsistency between the NRC's 
regulations and the AEA except for rulemaking.
    The savings of the final rule consist of the averted costs of 
licensees to prepare and submit license exemption requests and the 
averted costs of the NRC to review those license exemption requests. 
These averted costs are roughly split evenly between the licensees and 
the NRC. The NRC expects that licensees will also incur some minor 
costs to understand the final rule and to update their internal 
accounting guidelines. The costs for this rule will occur immediately 
after implementation of the final rule, as there are no costs to the 
rule over an extended period. In addition, the NRC does not expect that 
this rule will cause any entities to submit applications to

[[Page 21939]]

become class 104c licensees. The final rule also provides benefits to 
regulatory efficiency because it removes the inconsistency between the 
NRC's regulations in Sec. Sec.  50.21(c) and 50.22 and section 104c. of 
the AEA, which may create a lack of clarity for existing and future 
class 104c licensees. It also allows class 104c licensees to continue 
to operate as allowed under the AEA without concern for enforcement 
activities by the NRC. Based on this analysis, the NRC considers this 
rule to be cost beneficial to both industry and the NRC.

VI. Backfitting

    This final rule does not constitute ``backfitting'' as the term is 
defined in Sec.  50.109, ``Backfitting.'' This final rule applies to 
applicants or future applicants for certain licenses under 10 CFR part 
50. In general, applicants for licenses under part 50 are not the 
subject of the part 50 backfitting provision, with one exception not 
applicable to this final rule.
    The NRC is amending its rule text to be consistent with section 
104c. of the AEA. As such, rulemaking to align Sec. Sec.  50.21(c) and 
50.22 with section 104c. of the AEA constitutes a non-discretionary 
change. The Commission's policy in Management Directive 8.4, 
``Management of Backfitting, Forward Fitting, Issue Finality, and 
Information Requests'' (ADAMS Accession No. ML18093B087) is that non-
discretionary changes generally do not meet the definition of 
backfitting in Sec.  50.109.

VII. Plain Writing

    The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal 
agencies to write documents in a clear, concise, and 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 June 10, 1998 (63 FR 
31885).

VIII. National Environmental Policy Act

    The NRC has determined that this final rule is the type of action 
described in Sec.  51.22(c)(3)(i), which provides a categorical 
exclusion for amendments to part 50 that relate to procedures for 
filing and reviewing applications, amendments, or renewals for licenses 
or other forms of permission. Therefore, neither an environmental 
impact statement nor environmental assessment has been prepared for 
this final rule.

IX. Paperwork Reduction Act

    This final rule does not contain any new or amended collections of 
information subject to the Paperwork Reduction Act of 1995 (44 U.S.C. 
3501 et seq.). Existing collections of information were approved by the 
Office of Management and Budget (OMB), approval number 3150-0011.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, a collection of information unless the document requesting 
or requiring the collection displays a currently valid OMB control 
number.

X. Administrative Procedure Act

    Pursuant to 5 U.S.C. 553(b)(B), the NRC finds that there is good 
cause to issue this final rule without prior notice and comment. This 
final rule is limited to changes to make the NRC's regulations 
consistent with the amendments made to section 104c. of the AEA by 
NEIMA and the ADVANCE Act. The regulatory revisions are not subject to 
interpretation, and the NRC lacks any discretion regarding this change. 
Accordingly, notice and public comment procedures are unnecessary. For 
these same reasons, the NRC also finds good cause to waive the 30-day 
delay in the effective date under 5 U.S.C. 553(d).

XI. Executive Orders

    The following are Executive orders that are related to this final 
rule:

A. Executive Order 12866: Regulatory Planning and Review (as amended by 
Executive Order 14215, Ensuring Accountability for All Agencies)

    The Office of Information and Regulatory Affairs has determined 
that this final rule is not a significant regulatory action.

B. Executive Order 14154: Unleashing American Energy

    The NRC has examined this final rule and has determined that it is 
consistent with the policies and directives outlined in E.O. 14154.

C. Executive Order 14192: Unleashing Prosperity Through Deregulation

    This action is a deregulatory action as defined by E.O. 14192. 
Details on the estimated costs of this final rule can be found in 
Section V, ``Regulatory Analysis,'' of this document.

D. Executive Order 14270: Zero-Based Regulatory Budgeting to Unleash 
American Energy

    E.O. 14270, ``Zero-Based Regulatory Budgeting to Unleash American 
Energy,'' requires the NRC to insert a conditional sunset date into all 
new or amended NRC regulations provided the regulations are (1) 
promulgated under the AEA, the Energy Reorganization Act of 1974, as 
amended, or the Nuclear Waste Policy Act of 1982, as amended; (2) not 
statutorily required; and (3) not part of the NRC's permitting regime. 
The NRC determined that the regulatory changes in this final rule are 
limited to making the NRC's regulations consistent with statutory 
amendments and constitute part of the NRC's permitting regime 
authorized by statute. Therefore, the NRC views this rulemaking to be 
outside the scope of E.O. 14270 and did not insert conditional sunset 
dates for the regulatory changes in this final rule.

XII. Congressional Review Act

    This final rule is a rule as defined in the Congressional Review 
Act (5 U.S.C. 801-808). However, the Office of Management and Budget 
has found that it does not meet the criteria at 5 U.S.C. 804(2).

List of Subjects in 10 CFR Part 50

    Administrative practice and procedure, Antitrust, Backfitting, 
Classified information, Criminal penalties, Education, Fire prevention, 
Fire protection, Intergovernmental relations, Nuclear power plants and 
reactors, Penalties, Radiation protection, Reactor siting criteria,

    For the reasons set out in the preamble and under the authority of 
the Atomic Energy Act of 1954, as amended; the Energy Reorganization 
Act of 1974, as amended; and 5 U.S.C. 552 and 553, the NRC is adopting 
the following amendments to 10 CFR part 50:

facility is to be used so that:
    (1) more than 75 percent of the annual costs to the licensee of 
owning and operating the facility are devoted to the sale, other than 
for research and development or education and training, of nonenergy 
services, energy, or a combination of nonenergy services and energy; or
    (2) more than 50 percent of the annual costs to the licensee of 
owning and operating the facility are devoted to the sale of energy.
