Finland's OL3 nuclear reactor to resume typical output after technical issue

Finland's Olkiluoto 3 nuclear reactor, Europe's largest, will resume typical output after performing at lowered capability due to a technical issue, operator TVO said on Wednesday.

The reason for the disruption related to the unforeseen drop of the control rod in the OL3 reactor has actually been identified and the concern has been dealt with, TVO said on X.

OL3 had been running generally when the reactor's safety automation suddenly drove one control rod into the reactor on Wednesday, triggering a decrease in power output, TVO stated in a. statement.

The function of control rods is to change the power of the. reactor and, if required, to stop it, according to TVO.

The reactor was producing at a capacity of 446.9 megawatt. ( MW) at 1512 GMT, far below its capability of close to 1,600 MW,. TVO's site showed on Wednesday.

Production had actually been down to 340.6 MW previously in the day,. according to the operator's site.

The occasion had no influence on nuclear security, TVO stated.
