Finland's OL2 reactor to run at 14% decreased capability this winter

Finland's Olkiluoto 2 nuclear reactor will operate at a decreased capability of 725 megawatts ( MW), some 14% below it normal output this winter, to restrict the risk of failure of its generator rotor, operator TVO said on Friday.

The OL2 reactor has actually been offline because Sept. 9 due to a. fault with its generator rotor, which is being replaced with a. spare rotor.

TVO now stated it expected to restart the reactor, which has actually a. nominal capacity of 890 MW, on Oct. 6 however restricting output by 125. MW.

Since the root cause of the rotor damage is still. unclear, the system will remain on decreased power level to restrict the. threat of failure, TVO stated in a declaration.

This duration is anticipated to take several months, it included.

It presently anticipated the cut to last until May 25 of next. year, according to a different market message posted by means of power. exchange Nord Pool.

The extra rotor being utilized at OL2 is the last in TVO's stock. and the capability decrease is based upon a conservative analysis. to ensure electrical power production.

OL2's basic electrical power output accounts for about 8% of. the power used in Finland, according to TVO.

Electrical power production at the Olkiluoto 1 and Olkiluoto 3. reactors at the website remains untouched and continues as typical,. the operator included.
