The Olkiluoto Nuclear Power Plant (Finnish: Olkiluodon ydinvoimalaitos, Swedish: Olkiluoto kärnkraftverk) is one of Finland 's two nuclear power plants, the other being the two-unit Loviisa Nuclear Power Plant.

OL3 is an EPR (European Pressurized Water Reactor) plant unit with a net electrical output of approximately 1,600 MW. OL3 includes modern proven technology and advanced new safety features.

2024年3月8日 · Located in Finland, the Olkiluoto plant is owned and operated by Teollisuuden Voima. The Olkiluoto plant has been producing electricity for more than 40 years. The first unit, OL1, was commissioned in 1978, followed by OL2 two years later. The third unit, OL3, officially began operations in April 2023 and has a service life of 60 years.

2023年11月1日 · As a first-of-a-kind project, Olkiluoto Unit 3 took more time to build than was originally expected, but the end result has proven worth the wait. Calling it the “largest single climate action” in...

OL3 can be divided into three structural entities: the reactor building, the turbine building, and the auxiliary buildings. The tallest and most central structure is the reactor building that is comprised of a double-shell containment built of reinforced concrete.

2023年10月17日 · OL3 has been supplying electricity to the national grid for even longer. A significant date in history is also March 12, 2022. At that time, at 12:01, OL3 initiated its electricity production for the first time, although it was still clearly in a trial phase. Olkiluoto 3 is by far the most powerful plant unit in Finland.

2022年1月18日 · Scheduled to start commercial operations in the first half of 2022, Olkiluoto 3 (OL3) will be Finland’s first new nuclear reactor to come online in four decades. With a net power output of 1.6GW, OL3 will be the biggest nuclear reactor in Europe and the first European Pressurised Reactor (EPR) to be commissioned in the continent.

tvo公司称，ol3项目启动时，大约60%的芬兰人支持核电，而现在支持率提升到83%。 TVO公司CEO亚尔莫·坦瓦表示，启动OL3，不仅将稳定芬兰的电价，还将为芬兰绿色转型发挥重要作用。

2023年4月15日 · Finland's much-delayed Olkiluoto 3 (OL3) nuclear reactor, Europe's largest, began regular output early on Sunday, its operator said, boosting energy security in a region to which Russia has cut...

2023年5月2日 · Olkiluoto-3 is seen as a key component in Finland’s plans to reduce greenhouse gas emissions by 80% by 2050 and end reliance on foreign imports of electricity – more so since Russia’s war in Ukraine led to energy price rises throughout Europe.
