Hydraulic systems in nuclear power plants are primarily used for the circulation of fluid, often water or oil, which serves various functions such as cooling, transferring energy, and controlling the movement of machinery. The primary task of hydraulic pumps in this context is to generate the necessary pressure to circulate the coolant through the reactor core and heat exchangers effectively. This circulation helps to transfer heat produced during nuclear fission away from the reactor to the secondary circuit, where steam is generated to drive turbines for electricity generation.

There are several types of hydraulic pumps utilized in fluid power systems, including gear pumps, vane pumps, and piston pumps. Each type has its advantages and disadvantages depending on the application. Gear pumps, for instance, are known for their simplicity and reliability, making them a common choice for circulating fluids in nuclear facilities. Vane pumps offer a smoother flow and are better suited for applications requiring variable flow rates, while piston pumps are capable of handling high pressures and are often used in critical applications where reliability is paramount.
Safety is a primary concern in nuclear power plants, and the performance of hydraulic pumps is crucial in ensuring the safe operation of the facility. These pumps must be designed to withstand extreme conditions, including high temperatures and pressures, as well as potential exposure to radioactive materials. As such, materials used in the construction of hydraulic pumps must be corrosion-resistant and capable of enduring the harsh operational environment.
