Annual maintenance completed at Fortum's Loviisa nuclear power plant            

Both units of the Loviisa nuclear power plant are back in power production. The 
annual maintenance of Unit 1 took 50 days and ended on September 29. The        
start-up was delayed by slightly over a week due to troubleshooting and         
repairing the control rod.  Unit 2 was connected to the national grid as planned
on October 13 after an annual maintenance of 22.5 days. In both units, one third
of the fuel was changed.                                                        

Unit 1 underwent extensive annual inspection and maintenance, which is performed
every four years. The most extensive inspections were performed on the steam    
generators, the reactor pressure vessel and its inner parts, which were found to
be in good condition.                                                           

The automation systems of the power plant will be migrated gradually from       
analogue to digital by 2014. In the first phase, which took place during the    
annual maintenance of Unit 1, automation systems related to reactor functions   
and monitoring were taken into use.                                             

Unit 2 underwent a normal annual maintenance procedure, where the condition of  
the steam generators - one of the main objects of the inspection - was found to 
be good. The unit's large sea water pipelines were inspected and serviced as    
well.                                                                           

In addition to the 460 employees of the Loviisa power plant, approximately 1,000
inspection and maintenance professionals participated in the work, 150 of them  
foreigners.  Although there was much work and many workers, we were able to     
significantly reduce radiation doses and the number of occupational safety      
related accidents from the previous years. These excellent results are due to   
our long-term work to improve safety.
