A light water nuclear Reactor has been exergy analyzed, and the rate of irreversible exergy loss andexergy destruction is calculated for each of its components. The ratio of these losses compared to thetotal input exergy loss is calculated, which shows that most irreversible losses occur in the reactors,turbines, steam generators, respectively, as well as in the downstream operations. The main aim of thispaper is to optimize the power plant using an innovative firefly algorithm and then to propose a novelstrategy to improve the overall performance of the plant. As shown in the results, the exergy destructionrate of the plant decreased by 1.18% using the firefly method, and the exergy efficiency of the plantreached 29.3% comparing to the operational amount of 28.99%. Also, the results of the firefly optimization process compared to the Genetic algorithm and gravitational search algorithm to study the accuracy of the model for exergy analysis fitness problems in the power plants and the results of thiscomparison has shown that the results are nearly similar in the mentioned methods. However, the fireflyis faster and more accurate in limited iterations.
