Under the agreement, worth $466 million, the companies will refurbish one existing plant to become a coal-fired heat and electricity facility and construct another one to replace the three reactors that provide heat and electricity to the closed cities of Seversk and Zheleznogorsk in Siberia. After the fossil-fuel plants are successfully brought online, the existing reactors will be shut down. According to plans outlined in May, the Seversk plant will be refurbished by Washington International Group and activated in 2008. Raytheon Technical Services is tasked with constructing the new plant in Zheleznogorsk. Officials are eyeing 2011 as the year the last of the three targeted Russian nuclear reactors will cease operation.
