Nvidia is collaborating with German energy firm PreussenElektra GmbH (PEL) to explore converting old nuclear power plants into AI data centers. In an official announcement on October 21st, the U.S. chipmaker and the German firm entered a preliminary partnership to assess whether the latter's decommissioned nuclear power plant sites in Germany can be converted into high-performance AI data centers. The plan does not involve using nuclear power to power any future data centers. Instead, the project is focused on leveraging the existing power, water, and other infrastructure already present at the sites.
