Annual outage at Fortum’s Loviisa nuclear power plant to begin

PRESS RELEASE 2 August 2012

The annual outage at Fortum’s Loviisa nuclear power plant will begin on Sunday,
5 August 2012 on unit 1. The work on the two Loviisa power plant units will be
performed sequentially. The work on unit 2 is estimated to be completed by the
middle of October.

Loviisa 1 is scheduled for extended maintenance, which is done every eight
years. In addition to refuelling, extensive modification, repair, inspection
and testing work will be performed during the outage.

The most significant inspection and testing work on Loviisa 1 will include
inspections of the reactor pressure vessel and its internal parts, pressure
testing of the primary and secondary circuits, and tightness testing of the
steel liner of the containment building. The most significant maintenance,
repair and modification work includes modernisation of the primary circuit
pressure control, extensive replacement of seawater piping, replacement of one
of the two main generators with a refurbished one, and opening and servicing of
one low-pressure turbine.

Loviisa 2 is scheduled for a short annual outage. In addition to refuelling,
the most important annual outage work includes the periodic inspections of the
steam generators, replacement of one emergency diesel with a refurbished one,
and repairing of the reactor pressure vessel flange face sealing surfaces.

In addition to 500 power plant employees, approximately 1000 maintenance and
inspection specialists from a total of 80 companies will participate in the
annual outage work.

Annual maintenance guarantees safe and trouble-free functioning of the power
plant. Last year, the Loviisa power plant produced 8.06 terawatt-hours of
electricity, which is the equivalent of about ten per cent of Finland’s
electricity consumption. The capacity factor describing the plant’s
availability was 94.3 per cent last year, which is very high on an
international scale.
