It is the highest figure ever recorded for the United States, reinforcing the country&#8217;s position as the world&#8217;s leading nuclear power producer in terms of both installed capacity and actual generation.<\/p>\n<p>The figure comes from World Nuclear Association data and aligns with findings published by the U.S. Energy Information Administration, which in March 2026 certified 2025 as a record year for overall U.S. electricity generation \u2014 reaching 4.43 TWh in total, up 2.8% from 2024. Nuclear power contributed steadily throughout the year, holding a share of around 18\u201319% of the national electricity mix. As of May 2026, that share stood at 18.3%, with peaks of 59.5% in New Hampshire and 55.5% in New Jersey and Illinois.<\/p>\n<p>The growth outlook extends well beyond U.S. borders. <strong>The International Energy Agency projects new global nuclear generation records every year through 2030<\/strong>, driven by new reactor commissioning in China, restarts in Japan, and improved availability in France. On February 9, 2026, Japan restarted Unit 6 at the Kashiwazaki-Kariwa plant, offline since 2011 \u2014 a move the EIA expects to shift generation away from fossil fuels, primarily natural gas, which covered 33% of Japan&#8217;s electricity in 2024, toward zero-emission sources.<\/p>\n<p>On the technology front, the United States is opening a new chapter. In March 2026, the Nuclear Regulatory Commission issued a construction permit for <strong>TerraPower&#8217;s Natrium reactor<\/strong>, a sodium-cooled unit with a net output of 345 MWe \u2014 expandable to 500 MWe for up to five and a half hours via molten salt thermal storage \u2014 to be built in Kemmerer, Wyoming, on the site of a decommissioned coal plant. It is the first construction permit ever granted in the United States for a next-generation advanced reactor. The project, co-funded by the Department of Energy under the Advanced Reactor Demonstration Program with an initial $80 million, has also become a magnet for private investment: in January 2026, Meta signed an agreement to prepay for energy supply and support Oklo&#8217;s 1.2 GWe nuclear campus project in Ohio, while in June 2026 Walmart signed its first-ever nuclear power purchase agreement, securing around 176 MWe from Constellation&#8217;s Dresden plant in Illinois.<\/p>\n<p>The convergence of major tech corporations and nuclear producers marks a genuine shift in the energy market. This is not merely about decarbonization \u2014 it reflects real, urgent demand fueled by the explosive growth of data centers. <strong>Nuclear delivers where other sources fall short<\/strong>: reliability, energy density, and a minimal land footprint. If IEA projections hold and ongoing construction projects are completed on schedule, global nuclear output by 2030 could surpass current levels by a significant margin, returning the technology to the center of the energy debate \u2014 backed by data, not promises.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The United States generated 785.6 TWh of nuclear energy in 2025, an all-time record for its fleet of 94 operating reactors.
