TVO expects Areva to provide a detailed plan to complete the remaining works in OL3 project
Areva-Siemens Consortium who is building the Olkiluoto 3 nuclear power plant unit under a fixed price turnkey contract has informed that it is planning to focus efforts on the OL3 site on urgent design tasks, which are the most critical to the project. In this context the plant supplier is planning to reduce the number of subcontractors and work staff on the construction site.
For Olkiluoto 2, the production volume in 2012 was the best ever, 7.48 TWh.
At 96.9%, the capacity factor of OL2 was also a record for the unit. -The record
production was based on a short annual outage, trouble-free operation of the
plant unit and plant upgrades implemented during the annual outage, concludes
Mikko Kosonen, the Senior Vice President for Production.
The production
of Olkiluoto 1 amounted to 6.97 TWh in 2012. The generator breakdown in the
spring, which also made it necessary to start the annual outages earlier than
planned, is reflected in the lower production volume. Despite this, OL1 reached
a good capacity factor of 90.4%.
Major work carried out at OL1 during
the annual outage included e.g. replacement of the main generator, modification
of the discharge side of low-pressure turbines, modernisation of the I&C of
the condensate purification system, leak-tightness testing of the reactor
containment and replacement of one auxiliary transformer. The duration of the
annual outage at Olkiluoto 1 was a little over 31 days. After the completion of
the annual outage, a brief repair outage had to be further carried out due to a
faulty valve.
For OL2, the annual outage of 2012 was a brief refuelling
outage, which in addition to refuelling consisted of mainly inspections and
tests. The annual outage took a little over nine days at OL2. -All in all, the
annual outages went well and the plant units are in good condition for another
operating cycle. Owing to the plant upgrades implemented in 2010-2012, the
safety of the Olkiluoto nuclear power plant has been further improved and the
net electric output of both units has increased by ca. 20 Megawatts as a result
of the higher efficiency of the turbine plants, explains Mr. Kosonen.
