The General Confederation of Labor said staff at 16 of France's 19 nuclear plants have agreed to a one-day strike. French grid operator RTE's website showed nuclear power capacity has been cut by 4 gigawatts (GW), about 6% of total production capacity.

Nuclear power provides about 75% of France’s electricity. Workers at a major oil terminal in the port of Le Havre went on strike Thursday to block imports.

The strikes have spread to the railway sector where train drivers also staged a one-day strike Wednesday. The SNCF national rail authority said 25% of France’s high-speed TGV trains have been cancelled, and a similar number of regional and commuter trains have been affected.

Prime Minister Manuel Valls insists that the reforms will not be withdrawn but has suggested they could be modified.
