It was the first time that a nuclear plant had shut down in the US in more than 30 years, and the first nuclear shutdown since the Chernobyl disaster in 1986.
The plant was being operated by Entergy, the country’s largest utility.
It had shuttered its nuclear reactor at Three Mile Island, Pennsylvania, in the wake of a meltdown in the cooling tower that released toxic radioactive steam and melted steel.
But after more than 20 years of operating the plant, Entergy has shut down four reactors, and now plans to shut down another, at Sellafield in the United Kingdom.
The UK’s Department of Energy and Climate Change said on Thursday that it will no longer allow any more nuclear reactors to operate in the UK and the US, and announced that it would end the nuclear licensing process for existing nuclear power plants by 2035.
The UK government also announced that nuclear reactors are being retired in England, Wales and Scotland.
In its announcement, the Department of Climate Change stated that the decision to close the Sellafount and Three Mile island reactors was “due to the ongoing decommissioning of their reactors”.
The closure of the Sellacourse, which was built in 1952 and has been operating since 1976, is the first of a series of nuclear retirements announced by the US government, with the closure of two more reactors expected by the end of the year.
The US government also said that it was considering closing down its remaining nuclear power stations, including its fleet of six reactors at Westinghouse, at least one of which has been in operation since 1963.
The two new nuclear reactors at the Vogtle plant in Georgia are expected to be operational by 2025.
