This bill updates Arizona’s comprehensive planning process to accommodate small modular reactors (SMRs). It establishes a ‘nuclear-ready community’ designation, requiring communities to demonstrate readiness for SMR development through specific criteria and resolutions. The bill also modifies zoning regulations to prioritize SMR siting in these communities and requires comprehensive plans to consider the potential for SMRs and incorporate relevant data.
