France's new environment minister said Monday that nearly a third of the country's nuclear reactors could be shut under plans to scale back the amount of electricity produced from atomic power. In 2015, the previous Socialist-dominated parliament passed a law obliging the government to reduce the proportion of electricity generated from nuclear to 50 percent by 2025 compared with around 75 percent now. "We can all understand that to reach this target, we're going to have to close a certain number of reactors," Nicolas Hulot told RTL radio.
