Londonderry Township, PENNSYLVANIA — Three Mile Island, the 1979 partial nuclear reactor meltdown site, harkens back to the troubled times of Jimmy Carter‘s presidency, along with soaring gas prices, persistent stagflation in the economy, the Iranian hostage crisis, and the Soviet invasion of Afghanistan.

Forty-six years since the worst commercial nuclear accident in U.S. history, the Three Mile Island Generating Station has a much more positive glow — and not the threatening kind usually associated with radiation. Efforts to restart Unit One of the nuclear plant, near the state capital of Harrisburg, align closely with President Donald Trump‘s growing interest in carbon-free energy. Trump and his energy team are turning to nuclear as a reliable and cost-effective source of power in tandem with the administration’s embrace of fossil fuels to secure energy security.
