Campaigners have criticised Maldon District Council’s plans to lobby for a new nuclear power station in Bradwell.
The council said a new power station will be a “major economic stimulus” for the district and Essex.
In 2011 pressure group Bradwell Against New Nuclear Group collected a 10,000 signature petition against any future nuclear developments in the area.
Secretary Varrie Blowers said: “We are totally opposed to it. We are extremely worried about this.
“It seems unlikely that it will stop at just one power station. It could end up having up to three there."
