Community outreach, engagement and dialogue are cornerstones of our restart plan and inform the local community. It will be updated as new information and resources are available.

To ensure that the local community fully participates in the economic benefits of restarting the facility, Constellation has committed an additional $1 million in philanthropic giving to the region over the next five years to support workforce development and other community needs.

  • Restarting a nuclear reactor requires Nuclear Regulatory Commission approval following a comprehensive safety and environmental review, as well as permits from state and local agencies.
  • Constellation will pursue a license to extend operations to at least 2054 and expects the plant to be ready for service in 2027, after making a significant investment to fully restore the facility’s robust safety and operations systems.
  • There will be opportunities for the public to learn more about this application as part of the NRC’s review process.

 

 
  • Safety is Constellation’s first and most critical obligation. Nuclear power plants are among the best-protected private sector facilities in America, with monitoring and inspections by plant owners, local officials, and the federal government.
  • The Unit 1 reactor is located adjacent to TMI Unit 2, which shut down in 1979 and is in the process of being decommissioned by its owner, Energy Solutions. TMI Unit 1 is a fully independent facility, and its long-term operation was not impacted by the Unit 2 accident.  TMI Unit 1 was retired for economic reasons in 2019.
