Dungeness B nuclear reactor shuts down
Part of Dungeness nuclear power station in Kent has been shut down.
The Dungeness B reactor 21 was taken offline at 17:20 GMT on Wednesday following a fault on a conventional steam valve, EDF Energy said.
"Safety systems operated as they should and we took the conservative decision to bring the unit offline," the spokeswoman said.
Dungeness B has two reactors and the second remained operational.
