Sellafield nuclear plant in Cumbria has been closed due to "adverse weather conditions".
A statement on Sellafield Ltd's website reads: "The site emergency control centre has been established and is managing the incident in line with well rehearsed procedures. We have implemented a phased, early release of staff from the site; this is being carried out in a safe, controlled manner.
"There is no reason to believe that there will be any off-site nuclear, environmental or conventional safety issues associated with the incident. The priority for the team is to protect our workforce, the community and the environment."
The wintry conditions are now expected to last well into April with this month on track to become the coldest March since 1962.
A group of students from Wolverhampton who were stranded in extreme snow in Scotland for more than three days tell their story of survival.
Cold weather can pose a real health risk to older and disabled people, but everyone can gain from preparing their homes for the cold.
