OSLO, Nov 19 (Reuters) - Finland's Olkiluoto 3, Europe's largest nuclear power generator as measured by output, suffered an unexpected outage on Sunday due to a turbine problem, Nordic power bourse Nord Pool said in a statement. The 1.6 gigawatt (GW) unit, known as OL3, was expected to reconnect on Monday at around 1000 GMT, an extension of the outage by 11 hours compared to the initial estimate, according to the regulatory statement. Plagued by construction delays, OL3 began regular electricity output in April this year, some 14 years behind schedule. Finland has said the nuclear reactor, Europe's first in 16 years, is expected to meet around 14% of the country's electricity demand, boosting energy security.

☆ After 18 years, Europe's largest nuclear reactor starts regular output

The new reactor is expected to produce for at least 60 years, TVO said in a statement on Sunday after completing the transition from testing to regular output. "The production of Olkiluoto 3 stabilises the price of electricity and plays an important role in the Finnish green transition," TVO Chief Executive Jarmo Tanhua said in the statement. Construction of the 1.6 gigawatt (GW) reactor, Finland's first new nuclear plant in more than four decades and Europe's first in 16 years, began in 2005. Russian state export monopoly Gazprom shortly after ended shipments of natural gas to the Nordic nation.

HELSINKI, April 15 (Reuters) - Finland's much-delayed Olkiluoto 3 (OL3) nuclear reactor, Europe's largest, will begin regular output on Sunday, its operator said on Saturday, boosting energy security in a region to which Russia has cut gas and power supplies. Construction of the 1.6 gigawatt (GW) reactor, Finland's first new nuclear plant in more than four decades and Europe's first in 16 years, began in 2005. The plant was originally due to open four years later, but was plagued by technical issues. As a result of the startup, analysts have said Finland, the only Nordic country with a large power deficit, can expect lower electricity costs.

☆ Cracks found in Finnish OL3 nuclear reactor's feedwater pumps

COPENHAGEN, Oct 28 (Reuters) - Cracks of a few centimetres have been found in all four feedwater pumps of Finland's Olkiluoto 3 (OL3) nuclear reactor, operator TVO said on Friday, adding it was still unclear how the damage would impact the scheduled commissioning of the plant. The damage to Europe's largest nuclear reactor is a setback for Finland, where the national grid operator has warned of potential power blackouts in the coming winter if OL3 could not reliably supply electricity. "The root cause of the cracks found in the pump impellers is still unknown. The possible schedule impact will be communicated as soon as the results are available," TVO said on Twitter. Under construction since 2005, OL3 was originally meant to start operation in 2009, but has faced several technical mishaps, which sparked costly delays and a lengthy legal battle.

☆ Finland's OL3 nuclear reactor risks more delay after damage found

OSLO, Oct 18 (Reuters) - Damage has been detected in the feedwater pumps of Finland's Olkiluoto 3 (OL3) nuclear reactor during maintenance work, which will likely delay the commissioning of the plant and the startup of regular production, operator TVO said on Tuesday. The damage to Europe's largest nuclear reactor is a setback for Finland, where the national grid operator has warned of potential power blackouts in the coming winter if OL3 could not reliably supply electricity. Under construction since 2005, OL3 was originally meant to start operation in 2009, but has faced several technical mishaps, which sparked costly delays and a lengthy legal battle. Test production began this year, and regular electricity output at the reactor had been set to start on Dec. 14, TVO has said. "The damage detected at the pumps has no impact on nuclear safety," the company said on its website.
