A power company in the United States is planning to make use of retired nuclear reactors from the Navy’s aircraft carriers and submarines for a data center project proposed at Oak Ridge, Tennessee.

The step by HGP Intelligent Energy LLC is aimed at securing the massive amounts of energy for the artificial intelligence boom. For this, the company has approached the the Energy Department. The move is expected to produce about 450-520 megawatts of around-the-clock electricity. This could be helpful to fulfil the power needs of almost 360,000 homes.

The company argues that these reactors, which were originally designed to deliver reliable, long-lasting energy in demanding military environments, could be adapted to provide steady, carbon-free baseload electricity for data centers at a time when traditional grids are under strain. A small number of these reactors could collectively generate several hundred megawatts of power.

US aircraft carriers and submarines are each equipped with two reactors: A4W units made by Westinghouse Electric Co. or S8G-class units made by General Electric.
