PARIS, Oct 9 (Reuters) - A power sector strike reduced electricity generation at three French nuclear reactors and two coal-fired generators by 2.8 gigawatts (GW) on Tuesday, data by French power grid operator RTE showed.
The 24-hour strike by the energy branch of the hardline CGT trade union is part of a nationwide protest by several unions against President Emmanuel Macron's reforms.
RTE's data showed that power generation was reduced at EDF operated St. Laurent 1, Cruas 2 and Chinon 4 nuclear reactors, while output was at zero at the Cordemais 4 and 5 coal power plants.
The generators were expected to resume production later on Tuesday evening.
