“…This result concurs with statements by others that for new desalination installations, the preferred approach is reverse osmosis [21,25 ]. However, Nisan and Dardour state that although RO production costs are less than MED, the RO produced freshwater has a residual salinity on the order of 200 ppm whereas the MED value is only 25 ppm [26]. In the U.S., the Environmental Protection Agency (EPA) has established National Secondary Drinking Water Regulations (NSDWRs) which are non-enforceable guidelines.…”

There are direct links between water and energy use, sometimes referred to as the energy-water nexus. Water rights issues have confronted the southwestern U.S. for a long time. Furthermore, climate change is decreasing the already limited water resources in this region, and the growing population in the Southwest has also increased the consumption of freshwater. Here we study solar energy, which is abundant in the Southwest, as both an electric power source and the energy source to operate a desalination plant. We compare the use of different desalination technologies for seawater and brackish groundwater, which have different salinities. The data show that the dual-purpose reverse osmosis desalination plant is the most economical choice. However, since a multiple-effect desalination (MED) and a multistage-flash (MSF) can use waste heat for water production, desalinated water becomes a byproduct of the electric power plant, thus dual-purpose MED and MSF plants will be more economical than a single-purpose power plant. A MED plant using seawater or brackish water produces fresh water for $1.73/m 3 , while the costs are $2.811m 3 and $2.65/m 3 for a MSF plant using seawater and brackish water, respectively.

“…In this regard some research works have been carried out in literature. Nisan et al [8][9][10][11] showed that utilizing the waste heat from nuclear power plant for seawater desalination is more profitable than using fossil fuel for this purpose. The utilization of the GT-MHR waste heat for power production was proposed by Yari and Mahmoudi [12] who suggested using Organic Rankine Cycles (ORCs) for this purpose.…”

Abstract. An exploratory study has been carried out to evaluate the cost of heat supplied by a pressurized water reactor type of nuclear reactors to thermal desalination processes. In the context of this work, simplified models have been developed to describe the thermodynamics of power conversion, the energetics of multi-effect evaporation (MED), and the costs of electricity and heat cogenerated by the dual-purpose power plant. Application of these models show that, contrary to widespread belief, (nuclear-powered) MED and seawater reverse osmosis are comparable in terms of energy effectiveness. Process heat can be produced, in fact, by a relatively small increase in the core power. As fuel represents just a fraction of the cost of nuclear electricity, the increase in fuel-related expenses is expected to have limited impact on power generation economics.
