US EditionShutdown at Olkiluoto: "Technical failure on the nuclear island"
The automatic emergency shutdown halted electricity production for about 16 hours after a software update fault at the Olkiluoto 2 nuclear reactor, TVO said.
- On Friday, Olkiluoto 2 shut down after a fault began at 10:59, with Nord Pool estimating a 16-hour outage and production resuming at 3am on Saturday.
- A software update on the plant's 'nuclear island' caused a problem during the reactor power control system update, leading to unplanned unavailability; Mezha reported the outage may last no more than 16 hours.
- The Olkiluoto site in Eurajoki near Rauma hosts three reactor units, with OL1 and OL3 remaining in production while OL2, in service since 1982, is offline.
- TVO said the plant operated as planned and safety was not compromised, even as the outage reduces local generation amid the coldest temperatures and some 800 Finnish households already lack power.
- Market commentary split over whether the OL2 trip hurts nuclear investors as NuScale Power stock surged 12.9% through 12:40 p.m. ET Friday amid the SMR versus traditional nuclear debate.
