Sellafield nuclear plant given the all-clear after ‘elevated levels of radioactivity’ detected
The Sellafield nuclear plant has been given the all-clear after “elevated levels of radioactivity” were detected on Friday morning.
More than 10,000 non-essential staff were told to stay at home following problems at the site in Cumbria, which is the biggest nuclear site in the UK.
A perimeter alarm was triggered at the north of the site, leading to buildings being checked by safety staff, but it was later discovered the higher than normal levels were due to “naturally occurring background radon”.
It was the first time the site has been run on limited staff for safety reasons in recent memory, although a large number of staff were also told to stay away due to heavy snow last March.
A statement said: “Sellafield Ltd can confirm that the radioactivity detected by one of our in-air monitors overnight is not attributable to any issue or problem with any of our operations on site.
