  "account": "Scheduled annual maintenance at Finland's biggest nuclear reactor, Olkiluoto 3, began on Thursday. The reactor will be offline for around 50 days and is expected to conclude by the end of October, according to operator Teollisuuden Voima (TVO). TVO highlighted that such maintenance of the Olkiluoto reactors typically leads to increased end-user electricity prices. The autumn timing of the maintenance was chosen due to the extension of the reactor's operating cycle to 18 months. Olkiluoto 3 underwent its previous service in spring 2025, with the subsequent maintenance slated for March 2028. The maintenance encompasses uranium fuel replacement, essential repairs, and potential modification work. Earlier this year, the maintenance of Olkiluoto 1 and 2 was completed. On Thursday, it was reported that a few hours before Olkiluoto 3's scheduled disconnection, the unit was automatically disconnected from electricity production due to a technical fault. The reactor had already been operating at a reduced power level prior to the planned shutdown, and the incident presented no danger.",
