Arizona: SMR policy and licensing

Selected federal measures and selected state measures whose official text was opened. This is not a complete list of laws, rules or programmes for any jurisdiction. A state without a page here is not a finding that it has no policy, and these pages do not rate or prefer any state. Nothing here implies that a project is eligible for, or approved under, any measure.

Federal measures apply in Arizona as everywhere in the United States and are listed once on the federal page. They are not counted here.

Laws, rules and executive directives

• Arizona Chapter 56 of 2025: nuclear emergency management fund appropriation · In effect
  2025 Ariz. Sess. Laws ch. 56 (S.B. 1009) · Arizona Legislature · affects: Project funding
  Arizona Chapter 56, approved 18 April 2025, appropriates $2,617,991 for fiscal year 2025-2026 and $2,711,339 for fiscal year 2026-2027 from the nuclear emergency management fund and assesses those totals on consortia that construct or operate a commercial nuclear generating station. The opened page also prints four smaller lines for each year, and those lines do not add to the printed totals. The act does not permit a plant.
  Not approved or pending: No calendar effective date is stored. The opened chapter limits the appropriation and the assessment to fiscal year 2025-2026 and fiscal year 2026-2027. It does not print the calendar end of either fiscal year, so no expiry date is stored. The four allocation lines as printed do not add to the printed yearly totals, and this record does not reconcile them. No project is linked. The appropriation does not approve a reactor.
• Arizona Executive Order 2025-13: energy task force · In effect
  Ariz. Exec. Order No. 2025-13 · Governor of Arizona · affects: State programme administration
  Arizona Executive Order 2025-13, dated 15 September 2025, sets up an energy task force and tells agencies to help eligible nuclear projects, among other technologies, start construction for federal tax credits. It creates no project approval and says it confers no legal rights.
  Not approved or pending: The order does not permit a reactor, certificate a site, or appropriate state money for a nuclear project. The 30-day land-department report and the 1 March 2026 reports were not checked for delivery. No project is linked.

Bills, proposed rules and consultations

• Arizona S.B. 1418, vetoed: corporation commission and small modular reactors · Failed
  S.B. 1418, 57th Legislature, 2nd Regular Session (vetoed) · Arizona State Senate · affects: Siting
  Arizona S.B. 1418 was vetoed on 19 June 2026. The Senate fact sheet describes a certificate exemption for a co-located small modular reactor and a definition whose printed nameplate phrase is not more 300 megawatts. The veto means that text is not law.
  Not approved or pending: The enrolled bill and the veto letter were not opened. Current A.R.S. sections 40-360 and 40-360.03 were opened: a plant includes a nuclear unit of 100 megawatts or more, with a pre-13 August 1971 commitment exception, and a utility must apply for a certificate before construction. Those pages print no enactment date, so they are not a separate record. This veto does not decide any project.
