OKG2, one of three boiling water reactors at the site, currently has an installed capacity of 610 MW but the upgrade, using advanced three-dimensional blading technology will increase this by more than 30 MW.
Siemens will supply the low-pressure turbines, the high-pressure feed heaters, the flash tanks, and an SPPA-T2000 instrumentation and control system.
The contract was awarded by OKG AB, a Swedish subsidiary of E.ON, and the upgrades are slated for completion in 2009.
