Electricity production at the Olkiluoto 2 nuclear reactor in Finland was temporarily suspended in the early hours of Friday, operator TVO announced, while there appears to be “an increase in moisture detected at the turbine of the generator”, informs DPA, according to Agerpres.

It was initially unclear when the reactor would restart.

“The problem has no impact on nuclear safety,” TVO wrote on its website.

The nuclear power plant is located on Olkiluoto Island, west of the coast of Finland.

About four months ago, a third reactor, Olkiluoto 3, started operating after a delay of several years. According to TVO, it should be able to produce energy for at least 60 years.

Besides Olkiluoto, Finland has another nuclear power plant with two reactors, Loviisa.
