Thermo-economic Assessment of the Possible Desalination Processes for the Second Block of Bushehr Nuclear Power Plant

Abstract

Nowadays, the problem of supplying fresh water to scarcer regions of the world is still acute. The seawater desalination has been touted as the main solution of closing the water gap in the Middle East and North Africa. However, seawater desalination is expensive and energy-intensive and influences the environment, extremely. Using nuclear power is a viable alternative energy resource to decrease the set of problems of consuming fossil fuels in the desalination plants. Iran, which is located in the arid belt of the eastern hemisphere, as a member state of IAEA (International Atomic Energy Agency) has announced his interest in the implementation of dual-purpose nuclear desalination in the existing nuclear power plant of the country. The Bushehr nuclear power plant is the first commercial nuclear reactor in the Middle East and can be used as a multi-purpose atomic complex to meet the demand for energy and supply of water to arid regions in the south of the country. This paper performs a thermo-economic assessment study for different desalination strategies in the second block of Bushehr NPP.

Comparative Analysis of Hybrid Desalination Technologies Powered by SMR

“…In addition to the standalone thermal or membrane desalination technologies, two or more desalination processes can be coupled, which is called a hybrid desalination (HD) technique. Utilization of HD makes it possible to take advantage of both the thermal and membrane desalination processes [13].…”

“…As a tool for economic assessment, the newly introduced algorithm and developed software, Techno-Economic Analysis of Nuclear Desalination (TEAND), was utilized in the previous study [5]. While the previously published articles by authors [5,12,13,19,20] provide results of technical and economic analyses of large-scale nuclear-powered desalination systems, the present article focuses on a comprehensive thermo-economic assessment of the SMR integration to the hybrid large-scale desalination plant.…”

Feasibility of Hybrid Desalination Plants Coupled with Small Gas Turbine CHP Systems

“…For all the stated reasons, the obtained freshwater costs from thermal desalination units will be competitive with those produced by RO technology. In this paper, while the authors refer to their earlier works [4,6,[20][21][22][23][24][25], the focus is different, since the design process is applied to small CHP power plants intended for off-grid applications. In the next section, the proposed system is presented and deeply described, while in the following part of this paper, some economic analysis is presented in order to evaluate the cost of produced water.…”

Economic feasibility of solar-powered reverse osmosis water desalination: a comparative systemic review

“…Some articles revealed that renewable energy-powered renewable energy-powered desalination systems are economical in largescale desalination plants. The solar-powered large-scale RO systems can lower the cost by $0.37 to $0.74/m 3(Sadeghi et al, 2019). On the other hand, large-scale desalination is expensive, and water costs about twice as much as it does in a typical river or lake water puri cation operation (2011).…”

“…Since RO systems use high-grade energy and are power-hungry, the measures taken, including solar energy, have yielded a signi cant energy cost reduction of up to More evidence on the pro tability of solar-powered desalination has shown that it depends on area speci cities and desalination scale studies. For example, nuclear and solar energy, when used for smallscale desalination processes, are not cost-effective, but when used for large-scale desalination, they are economically feasible and cost-effective(Sadeghi et al, 2019;Tahri, 2001). Higher investment costs favor large-scale facilities that require a general low cost compared to traditional fuel-driven desalination plants.This indicates that solar-powered options will be viable in the coming years(Dawoud, 2017;El-Nashar, 2009;Zhang et al, 2018).…”
