Population growth, economic development, groundwater impairment due to salt water intrusion and local vulnerabilities caused by rising sea levels prompt immediate necessity for customized adaptation strategies for the cities of Homestead and Miami in Florida. This paper presents a feasibility study of nuclear energy driven cogeneration plant for water and power production in Homestead, FL. Miami-Dade and Homestead, Florida is home to the Turkey Point Nuclear Generating Facility. 

The focus of this study is to investigate the economic feasibility of a seawater desalination facility on the site of an existing nuclear generating plant. While the cost of seawater desalination is often too great to overcome, it is hypothesized that sharing the infrastructure and processes with a power generating facility will lower the cost of producing freshwater. The analysis was completed with the aid of the desalination modeling software, DEEP. First, we estimate the population growth and water demands for Homestead, FL and then identify a suitable water desalination plant configuration based on freshwater and power production costs. We compare cogeneration (water and power) schemes based on different energy sources and desalination technologies. The energy sources considered are nuclear energy, oil and natural gas for steam turbine and combined cycle power plants. In addition, we evaluate the water and power production costs for hybrid desalination configurations. Finally, the freshwater costs through nuclear desalination were assessed with other options and conventional ground water system costs. Environmental emissions saved through nuclear desalination and the need for considering this option despite the high costs are discussed in detail. The study concluded that reverse osmosis desalination plant powered by nuclear energy produced water at the lowest cost which is still three times the cost of current water rates in Homestead, Florida.
