“…Implementation of the HD technologies can lead to considerable enhance in the efficiency of large-capacity desalination processes [5]. The quality of produced freshwater, which can be determined by considering the amount of total dissolved solids (TDS), can be improved by including thermal desalination units, and lower energy consumption can be achieved by participating membrane desalination systems.…”

“…In the third suggested coupling scheme, the NPP condenser cooling water is used as feed water of DP. In this case, an increase in the feedwater temperature of RO membranes enhances their permeability, as a result of which, the RO plant recovery ratio usually increases by 1.5-3% per degree Celsius of temperature rise [5]. Making use of this configuration, the amount of feed water can be declined for constant freshwater production capacity in comparison to the other cases.…”

“…In RO systems, depending on the number of pre-filters and post-filters, various stages are used. Except for MVC, all of the stated thermal desalination processes require electricity and thermal energy (mainly in the form of low-temperature heat) to operate, whereas only electricity is required to drive the high-pressure pumps of RO unit [5]. 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.…”

“…It was concluded that the use of the HTR-PM reactor as an alternative to fossil fuel-based plants reduces the CO 2 emissions and increases the production capacity of desalinated water. A comprehensive techno-economic analysis of the hybrid desalination technologies integrated into a VVER type nuclear reactor was carried out in 2020, in which a new economic calculation algorithm was introduced to evaluate several hybrid desalination processes [5]. Other related previously published research is addressed elsewhere [19][20][21][22][23][24][25][26].…”

“…The program is capable of analyzing different integration schemes to compare the advantages and drawbacks of each case. 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.…”

Small modular reactors (SMRs) represent a key area of interest to nuclear industry developers, which have been making significant progress during the past few years. Generally, these reactors are promising owing to their improved safety due to passive systems, enhanced containment efficiency, and fewer capital costs in comparison to traditional nuclear reactors. An important advantage of SMRs is their adaptability in being coupled to other energy-consuming systems, such as desalination plants (DPs) to create a cogeneration plant. Considering the serious challenges regarding the freshwater shortage in many regions of the world and the necessity of using low-carbon energy sources, it is advantageous to use SMR for supplying the required heat and electricity of DPs. As a high-performance desalination technology, the hybrid desalination (HD) systems can be exploited, which retain the advantages of both thermal and membrane desalination methods. In this study, several SMR coupling schemes to HD plants have been suggested. In performing a thermodynamic analysis of integrated SMR-DP, the International Atomic Energy Agency (IAEA) Desalination Thermodynamic Optimization Program (DE-TOP) has been utilized. It has been found that the use of relatively hot water from the SMR condenser leads to about 6.5 to 7.5% of total desalination cost reduction, where the produced electricity and hot steam extracted from low-pressure turbine were used to drive the HD system.
