Strike continues at two French nuclear plants-CGT

PARIS, April 20 (Reuters) - Workers at France's nuclear power plants of Dampierre in central France and Chinon in southwestern France extended on Monday a strike which began on April 16, the CGT union said.

"Staff at Dampierre and Chinon voted to continue the action" a union spokesman told Reuters.

EDF said production was not affected at Dampierre but was not immediately able to say whether output had been curbed at the Chinon plant.

French energy workers voted on Friday to strike on April 21 and April 23 in an ongoing protest over salaries. (Reporting by Muriel Boselli and Mathilde Cru)
