Feasibility study of hybridizing a solar power plant with a small modular reactor for seawater desalination

The article discusses the technical and economic analysis of a seawater desalination plant, where the power source is a hybrid of solar and nuclear energy, as they are considered the cleanest energy sources compared to fossil fuel power plants. The source of nuclear energy in this study is a small modular reactor (SMR). This plant also uses a hybrid of seawater desalination systems: either a reverse osmosis plant with a multi-effect distillation (RO + MED) unit, or a reverse osmosis plant with a multi-stage flash distillation (RO + MSF) unit. Small modular reactors can be used for other applications besides generating electricity, as they produce high-temperature steam which can be used in many industrial processes such as hydrogen production and seawater desalination. Small modular reactors are also considered to be more cost effective, safer, more flexible and have a greater number of applications compared to high power reactors. The analysis is based on calculating the cost of producing of one cubic meter of fresh water using this hybrid desalination plant and comparing the results with those of desalination plant integrated with a power plant that uses exclusively nuclear energy as a source of thermal and electrical power, which uses the VVER-1200 reactor. Also, this study studies the impact of the degree of hybridization, that is, the ratio of power used from solar energy to power used from nuclear energy, on the cost of desalination of one cubic meter of water, as well as on the quality of the desalinated water.
