The Three Mile Island power plant, known for the worst nuclear accident in U. S. history, may be restarted to meet the growing energy demand of artificial intelligence developers. The plant, along the Susquehanna River in Pennsylvania, is part of a broader effort backed by the White House to reactivate mothballed nuclear facilities. Owner Constellation Energy has conducted tests on the dormant Unit 1 reactor and is considering restarting it, a process that would take several years. This push to revive nuclear plants is driven by clean energy subsidies and the need for zero emissions power as data centers and tech companies require more electricity.

However, concerns about safety, supply chain issues, and engineering challenges remain. Several nuclear plants have shut down in recent years, but some may still be functional if regulators approve power restoration. The move to revive nuclear plants has garnered mixed reactions from environmental groups. Critics argue that the rushing process might overlook safety hazards, while others believe it is a necessary step to meet energy demands and reduce reliance on polluting gas and coal plants.
