This paper presents a thermal-electrical model for all-electric ships with small modular reactors as the prime mover. The impact of the cooling system on the propulsion motor and generator's performance has been investigated. The study emphasizes the importance of considering the cooling system's design and operation in the all-electric ship's energy system. The study shows that neglecting the cooling system's effect on the propulsion motor may cause a temperature rise of up to 4°C degrees and an overload of the generator by up to 5 % in less than 10 seconds. The activation of the cooling system's pumps leads to a slight drop in voltage, which can impact the system's overall performance. The findings provide valuable insights into developing effective control strategies for the cooling system to improve the system's efficiency and reliability.
