In 2016, nuclear reactors were in operation in half of the EU Member States: Belgium, Bulgaria, the Czech Republic, Germany, Spain, France, Hungary, the Netherlands, Romania, Slovenia, Slovakia, Finland, Sweden and the United Kingdom, Eurostat, the statistical office of the European Union, shows. There were no nuclear facilities in the other 14 EU Member States.
The main use of nuclear energy is to produce electricity and, in 2016, gross electricity generation from nuclear plants within the EU Member States stood at 839.7 thousand gigawatt hours (GWh). In other words, nuclear plants generated about a quarter (25.8 percent) of the electricity produced in the EU in 2016.
France was by far the largest producer of nuclear power, with a 48 percent share of the EU total in 2016. It was followed by Germany (10 percent), the United Kingdom (8.5 percent), Sweden (7.5 percent) and Spain (7 percent). Together, these five Member States accounted for more than 80 percent of the total amount of electricity generated in nuclear facilities in the EU.
In 2016, nuclear reactors in the EU Member States have generated 839,684 GWh, with the distribution by country being uneven: France (401,195 GWh), Germany (84,634 GWh), United Kingdom (71,726 GWh), Sweden (63,101 GWh) (58,633 GWh), Belgium (43,523 GWh), Czech Republic (24,104 GWh), Finland (23,203 GWh), Hungary (16,054 GWh), Bulgaria (15,776 GWh) GWh) and the Netherlands (3,960 GWh).
From 1990 to 2016, most of the Member States operating nuclear facilities increased their nuclear electricity production. This was notably the case for the Czech Republic (+91.5 percent), followed at a distance by France (+28.4 percent), Slovenia (+23.6 percent), Slovakia (+22.7 percent), Finland (+20.7 percent), Hungary (+16.9 percent), the Netherlands (+13.1 percent), the United Kingdom (+9.1 percent), Spain (+8.0 percent) and Bulgaria (+7.5 percent). In contrast, Lithuania recorded the most significant decrease, as it closed down its nuclear facilities in 2009, ahead of Germany (-44.5 percent) and Sweden (-7.6 percent).
