Circulating Fluid Within Reactor

Circulating Fluid Within Reactor patent applications listed include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.

11/27/14 - 20140348287 - Dual fluid reactor
The present invention describes a nuclear reactor with a loop for liquid nuclear fuel, which, contrary to similar systems like the Molten-Salt Reactor of the Generation-IV canon, does not use the fuel loop for the heat transport at the same time. Instead, cooling is provided by an additional coolant loop,...

03/06/14 - 20140064432 - Particulate metal fuels used in power generation, recycling systems, and small modular reactors
A metal particulate fuel system is described. The metal fuel system may include particulate metal fuel for use in nuclear reactors. The particulate metal fuel may include a plurality of particles of at least one enriched alloy where the particles are compacted into a fuel column. The metal particulate fuel...

12/26/13 - 20130343505 - Pressurized water reactor
The pressurized water reactor according an embodiment comprises: a cylindrical reactor pressure vessel (1) to which inlet nozzles are connected; fuel assemblies which are contained within the reactor pressure vessel (1); a cylindrical reactor core barrel (3) which surrounds the fuel assemblies and forms an annular downcomer (6) between the...

05/02/13 - 20130108005 - Pressurized water reactor with upper vessel section providing both pressure and flow control
A pressurized water reactor (PWR) includes a vertical cylindrical pressure vessel having a lower portion containing a nuclear reactor core and a vessel head defining an integral pressurizer. A reactor coolant pump (RCP) mounted on the vessel head includes an impeller inside the pressure vessel, a pump motor outside the...

03/21/13 - 20130070889 - Double-walled tube with interface gap and production method therefor
After an inner wall tube, made of steel or alloy containing not less than 2% of Cr, whose outer surface thereof is machined and/or ground to a thickness of 0.1 mm or more including the scale layer, is inserted into an outer wall tube, made of ferritic steel containing not...

02/21/13 - 20130044852 - Treatment of a heater tube intended for a pressurizer of the primary cooling system of a nuclear reactor
A treatment of a heater tube intended to be used in a pressurizer of the primary cooling system of a nuclear reactor. In particular, the heater tube comprises a heater housed in a substantially cylindrical sheath. The material of which this sheath is made is a work-hardened austenitic stainless steel....

12/20/12 - 20120321030 - Integrated emergency core cooling system condenser for pressurized water reactor
A pressurized water nuclear reactor (PWR) includes a pressure vessel having a lower portion containing a nuclear reactor core comprising a fissile material and an upper portion defining an internal pressurizer volume. A condenser is secured to, and optionally supported by, the upper portion of the pressure vessel. A condenser...

09/01/11 - 20110211663 - Radiation exposure reduction method
A radiation exposure reduction method includes the steps of: injecting iron into a coolant which flows from the reactor cooling system to the reactor core in a nuclear power plant; and ferritizing and fixing radionuclides or parent nuclides thereof, which are contained in the coolant, on the surface of a...

11/18/10 - 20100290578 - Deployable electric energy reactor
A nuclear fission reactor device including a core having an array of fissile material and which is capable of being transported to and from the place of operation using conventional transportation vehicles. In a first embodiment, the fissile material is a uranium hydride enriched 15%-to-20% with U-235. In a second...

07/22/10 - 20100183113 - Jet pump and reactor
A jet pump has a plurality of nozzles installed to a nozzle base, a throat and a diffuser. A first nozzle straight-tube portion, a first nozzle narrowing portion, a second nozzle straight-tube portion, a second nozzle narrowing portion, and a nozzle lower end portion formed in those nozzles are disposed...

04/15/10 - 20100091931 - Reactor coolant pump flywheel
A flywheel for a pump, and in particular a flywheel having a number of high density segments for use in a nuclear reactor coolant pump. The flywheel includes an inner member and an outer member. A number of high density segments are provided between the inner and outer members. The...

10/08/09 - 20090252276 - Jet pump and nuclear reactor
the driving fluid passage is formed so that the driving fluid flowing toward the one end hits the first pipe member diagonally to the axial direction of the first pipe member....

06/18/09 - 20090154636 - Chemical injection system and chemical delivery process/method of injecting into an operating power reactor
An injection system designed to deliver a chemical solution into a reactor through feedwater system taps during normal operating condition of a power reactor is disclosed. The process of delivery is via positive displacement pumps. Injection of chemical is in a concentrated solution form, which is internally diluted by the...
