Budget means the funds appropriated by Congress for the NRC for each fiscal year, and if that appropriation is not passed on or before September 1 for that fiscal year, the funds most recently appropriated by Congress for the most recent fiscal year.

Budget authority means the authority, in the form of an appropriation, provided by law and becoming available during the year, to enter into obligations that will result in immediate or future outlays involving Federal Government funds. The appropriation is an authorization by an Act of Congress that permits the NRC to incur obligations and to make payments out of the Treasury for specified purposes. Fees assessed pursuant to Public Law 115-439 are based on the NRC's budget authority.

Bundled unit means the cumulative licensed thermal power rating of a number of SMR reactors on the same site that, for 10 CFR part 171 purposes only, is considered a single fee unit. The maximum capacity of a bundled unit is 4,500 MWt. A single SMR reactor can be part of two bundled units if it completes the capacity of one unit and begins the capacity of an additional unit. For a given site, the use of the bundled unit concept is independent of the number of SMR plants, the number of SMR licenses issued, or the sequencing of the SMR licenses that have been issued. The first bundled unit on a site is assessed a minimum fee for capacity less than or equal to 250 MWt, plus a variable fee for capacity greater than 250 MWt and less than or equal to 2,000 MWt. Bundled units with capacities greater than 2,000 MWt and less than or equal to 4,500 MWt are assessed a maximum fee that is equivalent to the annual fee paid by the current reactor fleet. The maximum fee replaces the minimum and variable fee for the first bundled unit. Each additional increment of 4,500 MWt of SMR capacity on the same site constitutes an additional bundled unit. No minimum fee is assessed to additional bundled units. For any additional bundled unit, a variable fee applies to capacities less than or equal to 2,000 MWt and the maximum fee applies to capacities greater than 2,000 MWt and less than or equal to 4,500 MWT. For additional bundled units, the maximum fee replaces the variable fee.

Byproduct material means -

Certificate holder means a person who holds a certificate of compliance, or other package approval issued by the Commission.

Commission means the U.S. Nuclear Regulatory Commission or its duly authorized representatives.

Federal fiscal year means a year that begins on October 1 of each calendar year and ends on September 30 of the following calendar year. Federal fiscal years are identified by the year in which they end (e.g., fiscal year 1987 begins in 1986 and ends in 1987).

Government agency means any executive department, commission, independent establishment, corporation, wholly or partly owned by the United States of America which is an instrumentality of the United States, or any board, bureau, division, service, office, officer, authority, administration, or other establishment in the executive branch of the government.

Greater Than Class C Waste or GTCC Waste means low-level radioactive waste that exceeds the concentration limits of radionuclides established for Class C waste in 10 CFR 61.55.

High enriched uranium fuel means uranium enriched to 20 percent or greater in the isotope uranium-235.

Low enriched uranium fuel means uranium enriched below 20 percent in the isotope uranium-235.

Materials license means a license, certificate, approval, registration or other form of permission issued or granted by the NRC under the regulations in 10 CFR parts 30, 31 through 36, 39, 40, 61, 70, 71, 72, and 76.

Maximum fee is the highest fee paid by a single bundled unit. It is applied to all bundled units on an SMR site with a licensed thermal power rating greater than 2,000 MWt and less than or equal to 4,500 MWt and is equal to the flat annual fee paid by existing fleet power reactors.

Minimum fee means one annual fee component paid by the first bundled unit on a site with a cumulative licensed thermal power rating of 2,000 MWt or less. For the first bundled unit on a site with a licensed thermal power rating of 250 MWt or less, it is the only annual fee that a licensee pays.

Non-power production or utilization facility means a production or utilization facility licensed under 10 CFR 50.21(a) or (c), or 10 CFR 50.22, as applicable, that is not a nuclear power reactor or production facility as defined under paragraphs (1) and (2) of the definition of “production facility” in 10 CFR 50.2.

Nonprofit educational institution means a public or nonprofit educational institution whose primary function is education, whose programs are accredited by a nationally recognized accrediting agency or association, who is legally authorized to provide a program of organized instruction or study, who provides an educational program for which it awards academic degrees, and whose educational programs are available to the public.

Nuclear reactor means an apparatus, other than an atomic weapon, used to sustain fission in a self-supporting chain reaction.

Operating license means having a license issued pursuant to § 50.57 of this chapter. It does not include licenses that only authorize possession of special nuclear material after the Commission has received a request from the licensee to amend its licensee to permanently withdraw its authority to operate or the Commission has permanently revoked such authority.

Person means:

Power reactor means a nuclear reactor designed to produce electrical or heat energy and licensed by the Commission under the authority of section 103 or subsection 104b of the Atomic Energy Act of 1954, as amended, and pursuant to the provisions of § 50.21(b) or § 50.22 of this chapter.

Quality assurance program approval is the document issued by the NRC to approve the quality assurance program submitted to the NRC as meeting the requirements of § 71.101 of this chapter. Activities covered by the quality assurance program may be divided into two major groups: those activities including design, fabrication and use of packaging and those activities for use only of packaging.

Registration holder as used in this part means any manufacturer or initial distributor of a sealed source or device containing a sealed source that holds a certificate of registration issued by the NRC or a holder of a registration for a sealed source or device manufactured in accordance with the unique specifications of, and for use by, a single applicant.

Research reactor means a nuclear reactor licensed by the Commission under the authority of subsection 104c of the Act and pursuant to the provisions of § 50.21(c) of this chapter for operation at a thermal power level of 10 megawatts or less, and which is not a testing facility as defined in this section.

Small modular reactor (SMR) for the purposes of calculating fees, means the class of light-water power reactors having a licensed thermal power rating less than or equal to 1,000 MWt per module. This rating is based on the thermal power equivalent of a light-water SMR with an electrical power generating capacity of 300 MWe or less per module.

Small modular reactor site (SMR site) is the geographically bounded location of one or more SMRs and a basis on which SMR fees are calculated.

Source material means:

Special nuclear material means:

Testing facility means a nuclear reactor licensed by the Commission under the authority of subsection 104c of the Act and pursuant to the provisions of § 50.21(c) of this chapter for operation at:

Variable fee means the annual fee component paid by the first bundled unit on a site with a licensed thermal power rating greater than 250 MWt and less than or equal to 2,000 MWt; or the annual fee component paid by additional bundled units on a site that have a licensed thermal power rating of less than or equal to 2,000 MWt. The variable fee is the product of the bundled unit thermal power capacity (in the applicable range) and the variable rate.

Variable rate means a per-MWt fee factor applied to all bundled units on site with a licensed thermal power rating less than or equal to 2,000 MWt. For the first bundled unit on a site with a licensed thermal power rating greater than 250 MWt and less than or equal to 2,000 MWt, the variable rate is based on the difference between the maximum fee and the minimum fee, divided by 1,750 MWt (the variable fee licensed thermal rating range). For additional bundled units with a licensed thermal power rating less than or equal to 2,000 MWt, the variable rate is based on the maximum fee divided by 2,000 MWt.
