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.
Claims25
A method of replacing a cesium trap, the method comprising:
- freezing a first cesium trap at least partially containing cesium therein, wherein the first cesium trap is located within a shielded cell;
- decoupling the first cesium trap from the shielded cell, wherein decoupling the first cesium trap comprises remotely decoupling a cell anchor extending from the shielded cell from a trap anchor extending from the first cesium trap, and wherein remotely decoupling the cell anchor from the trap anchor comprises removing a connection member that couples the cell anchor extending from the shielded cell to the trap anchor extending from the first cesium trap;
- removing the first cesium trap from the shielded cell;
- inserting a second cesium trap into the shielded cell;
- and
- attaching the second cesium trap to the shielded cell.

- removing the first cesium trap from the shielded cell, wherein removing the first cesium trap comprises:
- releasably coupling the first cesium trap to a lifting tool;
- and
- lifting, via the lifting tool, the first cesium trap out of the shielded cell such that a base of the first cesium trap slidably disengages with at least one locating pin extending from a bottom of the shielded cell, wherein lifting the first cesium trap separates a cooling line inlet extending from the first cesium trap from a fixed cooling line extending from the shielded cell;
- inserting a second cesium trap into the shielded cell;
- and
- attaching the second cesium trap to the shielded cell.
