The UNITHERM Russian reactor concept (Adamovich et al., 1997) is based on a transportable small-sized PWR concept that can be delivered to site in components. It would be appropriate for remote areas. It is designed for a life of 20 years with a single fuel loading for flexibility of location and with no requirement for a local cooling water supply. It comprises a dual loop system, the primary loop driving a turbine, the secondary system supplies steam or hot water for the intended process. The UNITHERM power plant was found (Grechko etal., 1998) to have a higher freshwater cost than fossil fuel plants but these plants could be found to be more economic than alternatives in remote access regions.
