appropriation; commerce authority; nuclear; study
HB 2388 appropriates funds to the Arizona Commerce Authority to study the economic impact of small modular nuclear reactors and data centers in Arizona. The study must examine job creation (direct, indirect, and secondary), potential tax revenue increases from property, sales, or income taxes, infrastructure needs, and other economic benefits. The Commerce Authority must submit a final report to state leaders and publish it online by a specified deadline. This bill does not enact new policy but directs a specific study to inform future decisions about these industries.
