Economic development and population growth require reliable supply of the ever-increasing demand for energy. The most convenient form of it is electrical energy. Therefore, designing and optimizing a power plant can help solve this issue. In this research, a nuclear and solar power plant along with a desalination plant was simulated in Thermoflow software, the simulated nuclear power plant was validated with similar research, then sensitivity analysis was performed on various parameters, the parameters of turbine pressure, condenser pressure, turbine inlet temperature and number of heliostats were selected as decision-making variables, and technical, economic and environmental evaluation was performed on them. The environmental impacts of the concentrate produced and the chemicals used in the reverse osmosis desalination plant were investigated. Due to the connection of Thermoflow to Excel, it is possible to connect Thermoflow to Matlab. First, a single-objective optimization whose function was the net output power and a dual-objective optimization function whose objective functions were the net output power and the levelized cost of electricity were performed. Finally, for the single-objective and dual-objective optimization, the net output power point was 86908kW, 73404kW, and the levelized cost of electricity was 0.076$/kWh, respectively. The amount of multi-stage flash freshwater was higher in the single-objective optimization, while since economic aspects are also considered in the dual-objective optimization, this amount decreases. Also, this amount does not change in the reverse osmosis desalination plant. In the case of concentrate, the more the amount of fresh water increased, the more the amount of concentrate produced, but in the dual-objective optimization this amount was lower. At the end of the study, solutions were proposed to reduce environmental impacts.
