The Olkiluoto 3 nuclear reactor on Finland's southwest coast has completed its production testing phase and is now fully operational. The 1,600-megawatt reactor provides about 14% of Finland's electricity generation.
The European Pressurized Reactor (EPR) was designed to revive nuclear energy in Europe, in the aftermath of the 1986 Chernobyl disaster. The new model is touted as offering both higher power and better safety, but its construction is proving to be a headache, and not only in Finland.
