“…The exergy efficiency of the nuclear reactor is compared with the exergy efficiencies of the nuclear reactor of the similar studies found in the literature and presented in Table 8. Norouzi et al's 26 designed study consists of a small nuclear reactor system that has very high thermal efficiency at about 96.35%. On the other hand, its exergy efficiency is calculated as 46.55%.…”

Summary In this study, a novel multigeneration plant driven by the heat energy coming from a nuclear reactor cooling fluid is designed, modeled, and analyzed. The primary aim of this multigeneration system is to generate useful products by using the waste heat of a nuclear reactor. The useful products of the multigeneration plant are electricity, heating, cooling, compressed hydrogen, drying, and freshwater. Then it is targeted to increase the plant's overall effectiveness by integrating sub‐plants. All parameters and thermodynamic balance equations are presented belonging to the multigenerational system and its sub‐parts. For the evaluation of the designed multigeneration system, thermodynamic analysis, including energy and exergy efficiency analyses with parametric analysis, is performed. The reference temperature, the nuclear reactor cooling fluid, and the pinch point temperature of the heat exchanger 1 are selected as parameters. The study's outputs reveal that the highest energy and exergy efficiencies are achieved as 66.69% and 60.82% when nuclear reactor cooling reactor temperature is 1000°C. Based on the performance assessment, the high and low‐pressure turbines could generate 3670 and 3137 kW, respectively, while the ORC turbine produces 9544 kW power.

Nuclear power plants play a significant role in global electricity generation, offering a reliable and low-carbon energy source. Maximizing the efficiency of nuclear power plants is crucial for optimizing energy output and reducing operational costs while ensuring safety and environmental sustainability. This paper presents a comprehensive review of the efficiency analysis conducted on nuclear power plants, covering various aspects such as thermal efficiency, conversion efficiency, fuel utilization, and overall plant performance. The review synthesizes the existing literature, discusses key factors influencing efficiency, and highlights potential areas for future research and improvements. It is revealed from the present review that the efficiency of the Boiling Water Reactor (BWR) of the Nuclear Power Plant is 32% and which can be increased to 33% by using advanced BWR. Also, the efficiency of the Pressurized Water Reactor (PWR) of the Nuclear Power Plant is 33% and which can be increased to 36.5% by using the PWR with Gas Burner and Reheating. On the other hand, the efficiency of the Small Modular Reactor (SMR) of the Nuclear Power Plant is 33.4% and which can be increased to 35.5%, 37.4% and 45% by using SMR with Gas Burner, SMR with Reheating and SMR with CCGT, respectively. Therefore, it is predicted that the Small Modular Reactor (SMR) is the most economic Nuclear Power Plant as it has higher thermal efficiency when it is incorporated with Combined Cycle Gas Turbine (CCGT).
