A fluid pump utilizing a canned rotor and canned stator is provided. The fluid pump has increased insulative properties over past &ldquo;spool-type&rdquo; pumps and has an increased ability to cool the stator, making it suitable for high temperature applications. A nuclear reactor is also provided. The reactor comprises a reactor vessel, that contains a nuclear fuel, control rods, reactor coolant and a reactor coolant pump for providing the reactor coolant to a steam generator. In a preferred embodiment, a steam generator is also provided inside the reactor vessel.

Nuclear reactor submerged high temperature spool pump

A pressure compensator for a sub-sea pumping system for pumping an effluent from a deep-sea wellhead comprising a topside module, a sub-sea module, and an umbilical connection between the topside and sub-sea modules. Hydraulic fluid is circulated through the sub-sea module for cooling and lubricating the motor and the pump. The hydraulic cooling and lubricating fluid is preferably a single hydraulic fluid that is compatible with the effluent being pumped. The hydraulic fluid is circulated through a submerged pressure compensator which may include a bellows assembly. The pressure compensator is responsive to the pressure of the effluent being pumped and pressurizes the hydraulic cooling and lubricating fluid to a pressure above the pressure of the effluent. The pressure compensator also responds when the volume of hydraulic cooling and lubricating fluid in the system is reduced or increased, such as by leakage or thermal expansion, in order to maintain the pressure of the hydraulic fluid.

Sub-sea pumping system and associated method including pressure

A sub-sea pumping system for pumping an effluent from a deep-sea wellhead comprising a topside module, a sub-sea module, and an umbilical connection between the topside and sub-sea modules. The umbilical connection comprises a threephase electrical power line and an hydraulic fluid supply line to an electrical canned motor. The hydraulic fluid is a single medium fluid, is compatible with the effluent being pumped, and is circulated through the sub-sea module for cooling and for lubricating the seal and bearing arrangements of the motor and the pump. The hydraulic fluid is circulated through a submerged pressure compensator which includes a metal bellows assembly. The compensator is responsive to the pressure of the effluent being pumped and pressurizes the hydraulic fluid flowing through the motor and the pump for the cooling and the lubricating of their respective seal and bearing arrangements at a pressure above the pressure of the effluent being pumped.

A fluid pump powered by an integral canned motor includes a housing having a cylindrical passage extending therethrough. A sealed annular stator is mounted around the housing. An impeller assembly is rotatably mounted in the passage in the housing. The impeller assembly includes an axial flow impeller and a sealed rotor mounted around the periphery of the impeller. Bearings, including thrust bearings, are mounted between the periphery of the impeller assembly and the housing. A radial flow auxiliary impeller may be mounted on the impeller assembly to create a radial flow of water from the cylindrical passage in the housing to a peripheral fluid circulation channel between the impeller assembly and the housing. The auxiliary flow impeller pressurizes the peripheral fluid circulation channel.
