“…The increased steam temperature from the super-heater also improves turbine performance and overall cycle efficiency. Morteza Gharib et al [10] described the thermal efficiency challenges faced by pressurized-water reactor (PWR) nuclear power plants, which currently operate at around 33% efficiency. This low efficiency has negative economic implications and contributes to environmental thermal pollution.…”

“…The possibility of increasing the thermal efficiency of PWRs is approximately 40% by superheating live steam with natural gas, making them more competitive with fossil-fueled power plants. [10] Boiling Water Reactor (BWR) Advanced BWR Most BWR reactors are typically 900-1100MW in generating capacity, with an efficiency of 32%. Early plants, mostly entering service in the early 1970s, were around 500-600MW in capacity.…”

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).

“…From all the accidents, one of the most important lessons has been learned that the control system of any reactor must be robust, efficient, and reliable at the same time. Several studies have been performed on nuclear reactor to ensure adequate safety, temperature control with an integrated safety system (Gharib et al, 2011;Hossain et al, 2019;IAEA, 2002;Sunday et al, 2013;Vojackova et al, 2017;Nain et al, 2019). The literature shows that the thermal-hydraulic models through hot channel fuel centreline temperature play a significant role to safety-related parameters within the design limit (Rahman et al, 2014).…”
