ALSTOM wins a major refurbishment contract at Swedish nuclear plant | Alstom


ALSTOM has won a 180 million euro contract to provide steam turbine and generator equipment as part of a major project to extend the plant life and increase the power output of Oskarshamn nuclear power plant in Sweden.

Under the contract with OKG Aktiebolag, owned by energy companies EON and Fortum, ALSTOM will supply new internal parts for the modernisation of turbine/generator Unit 3 of the three-unit plant. The turbine/generator set contains one high-pressure steam turbine, three low-pressure steam turbines and one generator.

In addition, ALSTOM will replace moisture separator reheaters, high-pressure heat exchangers, three single-phase main transformers, main steam valves and other balance of plant equipment, as well as carrying out dismantling, installation, commissioning and testing of the modernised plant.

Thanks to an upgrade of the nuclear reactors and the fully integrated design of the retrofitted turbine and generator equipment, the rated electrical power output at the Boiling Water Reactor (BWR) plant will increase from the current 1200 MW to more than 1450 MW. The project will ensure increased availability of the unit and extend the lifetime of the plant by more than 35 years.

The main installation work will be performed during a planned outage in 2008. The project will be managed and supplied from ALSTOM Power Sweden, and the site in Finspong. All major equipment will be produced at ALSTOM factories in France and Switzerland.
