France's oldest nuclear power plant, Fessenheim, was shut down on Saturday following an incident at the facility away from the reactor which did not pose any danger, operator EDF said, reports Reuters.
The accidental closing of a valve controlling the steam supply to the turbine generator automatically shut down Fessenheim's reactor 2. Technicians were working on the issue and a restart date had yet to be determined, an EDF spokeswoman told Reuters.
Fessenheim's reactor 1, the oldest in France, has been inactive since April 9 when a leak was detected in a water supply pipe.
"These are two incidents that have no bearing on the security of the plants nor for the environment," the spokeswoman said.
