An ion exchanger for a coolant circuit is provided with a housing that has an inlet and an outlet for a coolant. An ion exchanger medium is disposed in the housing. The housing is made of a plastic material and is an injection-molded part. A first plastic filter element is arranged in the outlet and embedded by injection molding in the first plastic material of the housing. In the inlet, a second plastic filter element is arranged and embedded by injection molding in the plastic material of the housing.

An apparatus for pretreating an ion exchange resin includes at least a stock solution tank for storing a non-aqueous solvent, an ion exchange resin container accommodating an ion exchange resin, and a moisture removal apparatus for removing moisture in the non-aqueous solvent, and at least one solution feed pipe selected from: a circulating solution feed pipe for returning, to the stock solution tank, the non-aqueous solvent that has passed through the ion exchange resin container and the moisture removal apparatus in this order from the stock solution tank; and a circulating solution feed pipe for returning, to the stock solution tank, the non-aqueous solvent that has passed through the moisture removal apparatus and the ion exchange resin container in this order from the stock solution tank.

A water softening ball for generating softened water by immersing it in water is provided, comprising a shell having a generally hollow ellipsoidal shape, wherein a plurality of openings are formed in the shell for the inside and the outside of the shell to communicate; and a filter unit included within the shell and comprising an ion exchange resin. The ellipsoidal shape includes a spherical shape.

An ion exchanger includes a case and an ion exchange resin. The case includes an inflow hole into which a refrigerant flows and an outflow hole out of which the refrigerant flows. The ion exchange resin is arranged in the case to remove ions from the refrigerant. The inflow hole and the outflow hole are located at a lower end of the case. The case accommodates a tube extending in a vertical direction and connecting to the outflow hole. The ion exchange resin is located between an inner wall of the case and an outer wall of the tube. The inflow hole is formed so that the refrigerant flows through the inflow hole into the case and evenly into the ion exchange resin from a lower end surface of the ion exchange resin.

A vessel for treatment of radioactive liquid. The vessel comprises a shielded housing defining an ion exchange chamber therein. The ion exchange chamber is configured to receive ion exchange media in its interior between an interior top surface and an interior bottom surface. The vessel further comprises an inlet diffuser disposed in the ion exchange chamber proximate the bottom surface and an outlet collection header disposed in the ion exchange chamber proximate the top surface. Also, the vessel comprises a process inlet in fluid communication with the inlet diffuser and a process outlet in fluid communication with the outlet collection header.

A vessel for removing radionuclides from a liquid. The vessel comprises a shielded housing comprising an outer shell and an inner shell disposed within the outer shell. The housing defines an ion exchange chamber between the inner and outer shells. The vessel also comprises an inlet fluidly coupled with the ion exchange chamber, the inlet being configured for fluid communication with a source of the liquid, and an outlet fluidly coupled with the ion exchange chamber, the outlet being configured for fluid communication with a destination of the liquid. The vessel further comprises a first fluid passage extending between an exterior of the vessel and the inner shell and a second fluid passage extending between the exterior of the vessel and the inner shell.

The invention relates to systems, apparatus and methods for the removal of cesium and other radionuclides from liquid waste contained in a high level waste tank. The invention includes transporting a stream of the liquid waste from the high level waste tank to one or more ion-exchange column assemblies to remove the cesium therefrom using a sorbent, such as, crystalline silico-titanate. The ion-exchange column assemblies include an ion-exchange column and an integrated shield. The column is concentrically positioned within the shield and an air gap is present between the column and the shield to provide passive cooling.

A media tank includes a housing having a first housing portion coupled to a second housing portion at an interface between the first and second housing portions, the first and second housing portions collectively defining an interior volume of the housing, and a divider positioned within the interior volume of the housing at the interface between the first and second housing portions to separate the interior volume into a first chamber at least partially defined by the first housing portion and the divider and a second chamber at least partially defined by the second housing portion and the divider. The first housing portion is coupled to the second housing portion via a friction weld at the interface. An annular gap is provided between the divider and the first housing portion. Flash from the friction weld is received within the annular gap.
