Economic Prospective of Small/Medium Nuclear reactors for Hybrid Seawater Desalination Systems
Journal of Engineering Science and Technology Review
Technical and economic analysis of the most recent reported world experience of small/medium nuclear reactors (SMRs)are essential to decision making regarding dual purpose power/water generation in developing countries. In this work, firstly, analysis of reported economic aspects concerning SMRs has been highlighted. A desalination system of 150,000 m3 water production capacity to cope with the need of small community (about 375,000 persons) has been then proposed. Techno-economic study has
... nomic study has been performed among small/medium reactors (SMR) to identify the appropriate power source for the integrated power desalination complex. IRIS nuclear reactor shows the lowest power cost of $0.029/KWh in the choice matrix of different SMRs with thermal output less than 1000 MWth. The selected reactor "IRIS" gives the ability to combine the desalination plant with a thermal desalination plant (MSF) type in a hybrid configuration scheme involving MSF/RO with varying ratios. Sensitivity analysis of hybrid desalination process shows that, at MSF/RO ratio 11% the unit water cost is $0.77/m3, the lowest water cost has been approached for RO system (0.73 $/m3) in an inverse relationship with permeate TDS. Empirical cost correlations have been developed for the corresponding permeates concentration.
