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 · The Olkiluoto 3 (OL3) is the third most powerful nuclear power generation unit in the world with a net electrical output of 1.6GW. Located in Finland, the Olkiluoto plant is owned and operated by Teollisuuden Voima.

Olkiluoto 3 (OL3) was decided to build for many reasons. The added capacity brought by OL3 not only meets the increasing demand but also compensates for the decreas-ing output of ageing power plants. Together with the use of renewable energy, the unit helps Finland to reach its carbon dioxide emission targets, contributes to the sta-

2025年3月12日 · A leakage of some 100 cubic metres of reactor coolant occurred at unit 3 of Finland’s Olkiluoto NPP (OL3) related to the filling of the reactor pool, plant operator Teollisuuden Voima Oyj’s (TVO) reported. The coolant flowed into containment rooms closed to the environment and into the floor drain system of the containment.

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4月16日 · Finland’s much-delayed and costly new nuclear reactor has completed a test phase lasting more than a year and has started regular output. It has significantly boosted the Nordic country’s electricity self-sufficiency. The Olkiluoto 3 reactor has 1,600-megawatt capacity and is Europe’s most powerful by production capacity.

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.

2023年11月1日 · And with the start of regular production from Teollisuuden Voima Oyj’s (TVO’s) 1.6-GW Olkiluoto Unit 3 (OL3) in April this year, the amount of nuclear power generated in Finland took a big ...

2024年9月19日 · Finnish utility Teollisuuden Voima Oyj has today received permission from the country's Radiation and Nuclear Safety Authority to bring the Olkiluoto 3 EPR to first criticality and conduct low-power tests. The unit is expected to begin generating electricity at the end of January, with regular electricity production starting in June 2022.
