Nuclear Power Plants in Finland and Sweden

Agesta Location: Sweden Operator: Vattenfall Configuration: 1 X 12 MW PHWR CHP Operation: 1964 (ret) Reactor supplier: ASEA T/G supplier: ?? Quick facts: This installation in Stockholm's southern Farsta suburb was Sweden's first reactor and one of the only nuclear plants ever used for district heating. Thermal capacity was 105 MWt. Construction began in 1957 and the unit was declared commercial 1 May 1964. The unit used natural uranium and heavy water from Norway and operated for 52,000hr. The reactor and electromechanical equipment were housed inside a rock cavern blasted out of a hillside with a cooling tower placed outside on the hilltop. The two steam generators have been removed but much of the rest of the equipment is intact in safe storage conditions.

Criticality on Unit-1 was 18 Jan 1975 and Unit-2 was connected on 21 Mar 1977. In 1997, the Swedish government passed an Act giving them the right to order Swedish nuclear plants to close under certain circumstances. Despite opposition from the power companies and other industries, the government uses the Act order the Barsebäck units to close in 1998 and 2001, respectively. The closures were delayed somewhat, but Unit-1 was taken offline 30 Nov 1999. In 2002, a large-scale modernization program was completed on the Unit-2, and in 2004, the unit had its best year ever with generation of 4.7 TWh. Unit-2 was closed permanently on 31 May 2005.

Unit-3 has been uprated to about 1,360 MW with testing underway to determine the final value. Photograph by Hans Blomberg and courtesy of Vattenfall Posted 28 Apr 2004
Loviisa Location: Finland Operator: Fortum Power & Heat Configuration: 2 X 510 MW PWR Operation: 1977-1981 Reactor supplier: Atomenergoexport T/G supplier: Kharkov, Electrosila Quick facts: In 2009, Loviisa produced 8.16 TWh of electricity with an availability factor of 95.7%, both records for the plant. The site is on the Baltic about 80km from Helsinki. In 2008/09, Fortum completed the first phases of a major retrofit of digital automation for control and monitoring activities. In Feb 2009, Fortum submitted to the government an application for a decision-in-principle concerning the construction of a third unit at Loviisa.

TVO took responsibility for licensing, site preparation, excavation, plus the switchyard, cooling water intake and outfall, pier, and ancillary buildings. The construction license was issued on 17 Feb 2005 and first structural concrete was poured in Mar 2005. Total investment by the owner was fixed at €3bn, but at last report the total cost may reach €3bn. This is the largest-ever industrial project in Finland. Photo is from Mar 2013.
