    Global nuclear reactor buildout totals 77 units as 2045 power demand expands 60%

    Question

    Global nuclear reactor buildout totals 77 units as 2045 power demand expands 60%

    Direct answer

    With 77 reactors under construction globally, nuclear energy capacity expansion is heavily skewed toward Asian markets, leaving Western grids constrained. U.S. utilities and merchant operators are seeking long-term power purchase agreements directly with data center operators. Cameco and Constellation Energy remain key beneficiaries as hyperscalers pursue dedicated carbon-free base-load electricity.
