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 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.
