NRC Sets Yearlong Review of Three Mile Island Restart With Public Comment Opening Feb. 24

Inspectors plan roughly 8,000 hours of licensing and field checks, with Constellation targeting a mid‑2027 return under a long‑term Microsoft power agreement.

Overview

  • Federal regulators and Constellation briefed residents at Penn State Harrisburg as the restart enters an intensive inspection phase focused on safety-critical systems.
  • Formal windows open Feb. 24 for a 30‑day public comment period and 60‑day petitions for hearings before NRC administrative judges.
  • To date, the only approved action is the plant’s name change to the Christopher M. Crane Clean Energy Center, with most license decisions not expected until 2027.
  • Officials clarified that electricity from a restarted Unit 1 would flow into the PJM grid rather than directly to a planned nearby Microsoft facility.
  • Constellation says the plant is fully staffed and training operators for a mid‑2027 restart, while supporters cite jobs and 835 MW of capacity and critics question safety and regulator independence.
