Additionally, the Three Mile Island project will generate $3.6 billion in tax revenue at the state and federal levels, benefiting Pennsylvania's economy and the federal government.
The History of Three Mile Island and the 1979 Nuclear Accident
Three Mile Island has been synonymous with nuclear disaster since 1979 when Unit 2 of the plant suffered a partial core meltdown, releasing small amounts of radiation. This incident at Three Mile Island is considered the most serious in the history of commercial nuclear energy in the United States.
Fortunately, there were no injuries or long-term health effects on residents near Three Mile Island. However, the accident raised public distrust in nuclear energy and led to stricter regulations for the operation of nuclear plants across the country.
Despite the notoriety of the plant, Unit 1 of Three Mile Island, which is the one that will be reactivated, was unaffected by the 1979 accident. This unit of Three Mile Island has operated independently and without problems until it was shut down in 2019 for economic reasons.
Now, with the planned improvements and regulatory revisions at Three Mile Island, it is expected that this unit will resume operation safely and reliably under Microsoft’s management.
Challenges of Reactivation: Safety and Nuclear Waste
While the reactivation of Three Mile Island represents a significant technological and economic advancement, it also faces challenges. One of the main concerns raised by local residents and environmental advocates is the management of nuclear waste at Three Mile Island.
