On 18 November 2024, Loviisa Nuclear Power Plant’s second unit power production was interrupted due to a fault.
On Monday, 18 November 2024 at approximately 20:55 local time, the electricity production of the second unit of the Loviisa Nuclear Power Plant was interrupted due to a fault. The plant's first unit continued operating normally. Fortum, the operator, stated that the fault did not cause danger to people, the environment, or the facility. The cause of the fault is under investigation. This follows a similar incident on Sunday at Olkiluoto Nuclear Power Plant where power production ceased temporarily.
Confidence: High
The article reports a technical fault interrupting power production at the Loviisa nuclear plant without any attribution or evidence of hostile action or defense activity. It is a disruption of critical infrastructure but not caused by aggression or linked to defensive measures.
