<P> On the first anniversary of the Fukushima nuclear disaster, organisers of French anti-nuclear demonstrations claim 60,000 supporters formed a human chain 230 kilometres long, stretching from Lyon to Avignon . Austrian Chancellor Werner Faymann expects anti-nuclear petition drives to start in at least six European Union countries in 2012 with the goal of having the EU abandon nuclear power . </P> <P> In March 2014, police arrested 57 Greenpeace protesters who used a truck to break through security barriers and enter the Fessenheim nuclear in eastern France . The activists hung antinuclear banners, but France's nuclear safety authority said that the plant's security had not been compromised . Although President Hollande promised to close Fessenheim by 2016, and Greenpeace continues to demand immediate closure, Fessenheim continues to operate without problems . </P> <P> In 2007, Areva NC claimed that, due to their reliance on nuclear power, France's carbon emissions per kWh are less than 1 / 10 that of Germany and the UK, and 1 / 13 that of Denmark, which has no nuclear plants . Its emissions of nitrogen oxide and sulfur dioxide have been reduced by 70% over 20 years, even though the total power output has tripled in that time . </P> <P> If done without environmental or health over-sight, conventional mining for uranium can produce large amounts of mining tailings and contaminated water but as of 2010, about half of the world's uranium supply is increasingly generated from In situ recovery (ISR) technology, that does not require physical mining in the conventional sense and if responsibly operated is considerably cleaner . Another alternative to ISR is remote controlled underground mining, the French owned Areva Resources Canada owns a large stake in the Canadian McArthur River uranium mine, the world's highest grade and largest uranium mine by output, the underground remote operation of mining vehicles in this mine, is designed to keep personnel exposure to rock particulates and radon gas etc. low . The mine is a frequent winner of the John T. Ryan National Safety Trophy award in Canada, which is bestowed upon the safest mine in the country every year . </P>
