Authorities shut down a reactor at one of France's largest nuclear power plants on Sunday following a fire in a non-nuclear portion of the plant, officials said.
Managers at the atomic energy plant in Cattenom in the Moselle region of north-eastern France said a fire had broken out in the electrical cables in the conventional part of the factory.
"According to procedure, the reactor (number two) was shut down," they said, adding that the incident led to the declaration of an internal emergency for the plant operator Electricite de France.
The fire at the plant some 280 kilometre's (175 miles) east of Paris.
