The Olkiluoto 3 nuclear reactor in Finland is leaking radioactive coolant, believed to be due to human error.
The turbine room is connected to OL3, the newest of three reactors at the Olkiluoto nuclear power plant on the island of Eurajoki in western Finland.
AFP reported on March 10, citing a statement from TVO, the company operating the Olkiluoto 3 nuclear reactor in Finland, that approximately 100 cubic meters of "radioactive coolant" leaked from the reactor, but the incident did not pose a safety risk.
The leak occurred on March 7 during the reactor's annual shutdown for maintenance, "related to filling the reactor containment pool," according to the statement.
"The coolant leaked into containment chambers near the environment and into the chamber's floor drain system. This incident does not pose any risk to personnel, the environment, or nuclear safety," TVO stated.
According to TVO, the leak was attributed to "human error" because the tank's hatch was not properly closed. "Ultimately, the level of the incident regarding radiation safety was low, as safety measures were taken," TVO announced.
TVO added that this incident will not affect the planned annual shutdown, which is expected to last until May.
The next-generation European pressurized water reactor (EPR), built by the French-led Areva-Siemens group, supplies more than 10% of Finland's electricity.
Like several other EPR projects, this reactor located on the southwest coast of Finland has suffered repeated construction delays and cost overruns of billions of dollars.
Olkiluoto 3 is the largest nuclear reactor in Europe, while Ukraine's Zaporizhzhia nuclear power plant, with 6 reactors, is the largest nuclear power plant.
