In nuclear reactors, process as well as power water hydraulics is extensively used to avoid intermixing of oils with water which is used as coolant and moderator. A Fuelling Machine (FM) is used for on-power refueling of Pressurized Heavy Water Reactor (PHWR) and Advanced Heavy Water Reactor (AHWR). Many mechanisms of FM are operated under water environment to handle the fresh as well as used fuel. Use of Water Hydraulic (WH) actuators is preferred to actuate these mechanisms. It is desirable to use water hydraulic direct drives like High Torque Low Speed (HTLS) rather than using high speed motors with mechanical multipliers like gearbox, working inside the water environment. Mechanical multipliers avoided as they are prone to tribological problems like insufficient lubrication, high wear rate and friction, corrosion etc. under water environment. Water Hydraulic HTLS motors are not available in market, hence there is need to develop it indigenously. WH motor with radial piston configuration is one of the promising options for HTLS motor since in this design, as it has less number of moving parts and less dynamic sealing locations. This paper discusses comparison of various design configurations of hydraulic motor, problems associated with design of water hydraulic components and engineering solutions to overcome the same, theoretical analysis of radial piston HTLS motor.
