The Work Ahead Before Historic Restart of Constellation’s Three Mile Island Nuclear Plant
In a historic move, Constellation Energy is set to restart the Three Mile Island Unit 1 nuclear reactor.

This ambitious project aims to revive a significant source of clean energy, but it comes with substantial technical, regulatory, and financial hurdles.
Key Challenges
Regulatory Approval: Before restarting, the Nuclear Regulatory Commission (NRC) must approve the return to operations. This involves restoring the licensing basis and ensuring compliance with safety standards.
Hardware Rejuvenation: Major plant components, such as the main power transformer, need replacement or refurbishment. Constellation has already ordered a new transformer costing about $100 million.
Workforce Development: Restarting a nuclear plant requires skilled personnel. After shutdown, many experienced workers leave, making recruitment and training a significant challenge.
Financial Investment: Constellation plans to spend approximately $1.6 billion on the restart, including a 20-year power purchase agreement with Microsoft to support the project financially.
Opportunities and Impact
Energy Demand: The restart is driven by increasing energy demands from tech companies like Microsoft, which require reliable, low-carbon power for their data centres.
Economic Benefits: The project will create hundreds of jobs and stimulate local economic growth, making it an economic success story for Central Pennsylvania.
Environmental Impact: Reviving nuclear plants can help reduce reliance on fossil fuels, contributing to a cleaner energy mix and supporting climate goals.
