PRESS RELEASE 29 August 2012

Fortum's Loviisa nuclear power plant’s reactor unit 2 shut down due to a
turbine trip today, 29 August at 3.23 p.m. local time. The turbine trip was due
to annual maintenance work at Unit 1, causing both turbines of Unit 2 to trip,
whereafter the reactor was shut down. Due to the incident, a general "all
clear" alarm signal went off twice, unnecessarily.

The shutdown caused no threat to people, environment or the power plant.
Reasons for the disturbance are being investigated.
