Abstract
A method for replacing a cesium trap includes freezing the cesium trap which partially contains cesium and is located within a shielded cell and. The cesium trap is then decoupled and removed from the shielded cell. A second cesium trap is inserted into the shielded cell and attached to the shielded cell.
Claims9
A cesium trap comprising:
- a body comprising a top portion, the body enclosing a filter and an active material configured to remove cesium from a sodium stream;
- a cooling jacket disposed around the body;
- at least one trap anchor extending from the cooling jacket, wherein the trap anchor is releasably couplable to at least one corresponding cell anchor extending from a shielded cell in which the body is disposed so as to form at least one lateral support anchor;
- at least one first sodium line extending from the top portion, wherein the at least one first sodium line is configured to couple in flow communication with a corresponding at least one second sodium line of a sodium processing circuit;
- and
- a base coupled to a bottom portion of the body, wherein at least one opening is defined within the base such that the base is positionable within a bottom of the shielded cell via at least one corresponding locating pin.

A cesium trap comprising:
- a body comprising a top portion, the body enclosing a filter and an active material configured to remove cesium from a sodium stream containing cesium and argon;
- at least one trap anchor extending from the body, wherein the trap anchor is releasably couplable to at least one corresponding cell anchor extending from a shielded cell in which the body is disposed so as to form at least one lateral support anchor;
- a base coupled to a bottom portion of the body, wherein at least one opening is defined within the base such that the base is positionable within a bottom of the shielded cell via at least one corresponding locating pin;
- and
- at least one first sodium line extending from the top portion, wherein the at least one first sodium line is configured to couple in flow communication with a corresponding at least one second sodium line of a sodium processing circuit;
- wherein the filter is located to prevent the active material from leaving the cesium trap while allowing the sodium and argon to pass and the filter has a mean pore size of from 40 to 160 μm.
