US nuclear power uprates surge to meet AI data center demand

The United States is increasing its nuclear power output not by building new reactors, but by upgrading existing ones. These "power uprates," approved by the Nuclear Regulatory Commission, have already added approximately 6 GW of capacity over the last two decades, with an estimated 6-8 GW more potentially available in the coming years. This surge in nuclear power is largely driven by the immense energy demands of AI data centers, prompting significant investments in refurbishing existing plants. AI

IMPACT Accelerates deployment of clean energy infrastructure to meet the growing, substantial power demands of AI computation.

RANK_REASON Significant investment and policy action to increase existing nuclear power capacity, driven by a major industry trend (AI data centers). [lever_c_demoted from significant: ic=1 ai=0.7]

    The fastest new nuclear power in the United States is not a new reactor. It is the old ones running harder. A "power uprate", approved by the Nuclear Regulatory Commission after turbines, pumps and controls are upgraded, has added about 6 GW to the grid over the past twenty years…
