Device for magnetically removing a capsule containing Co-60 from a burnable absorber rodlet

1. An apparatus for removing irradiated burnable absorber (BA) capsules, the apparatus comprising:

a BA capsule removal module supported by a control arm,

wherein the BA capsule removal module is positionable via the control arm around a BA rodlet comprising a paramagnetic outer cladding material;

wherein the BA capsule removal module defines a capsule removal tunnel configured to be slidably positioned around the BA rodlet,

wherein the capsule removal tunnel defines first and second tunnel openings at corresponding first and second ends of the capsule removal tunnel, and

wherein the first and second tunnel openings define a distal radius R 1 that linearly tapers to a smaller inner radius R 2 ;

wherein the BA capsule removal module comprises:

a plurality of bearing columns equidistantly spaced in the capsule removal tunnel,

wherein the bearing columns comprise bearings configured to contact the BA rodlet positioned inside the capsule removal tunnel, and

 wherein the bearings allow the BA capsule removal module to slidably move along a longitudinal axis of the BA rodlet; and

a solenoid positioned around the capsule removal tunnel and configured to electrically induce an electromagnetic flux in a BA capsule inside of the BA rodlet, wherein the BA capsule comprises a ferromagnetic material,

wherein the electromagnetic flux magnetically locks the BA capsule to the BA capsule removal module, and

 wherein while locked, axial movement of the BA capsule removal module positioned outside of the BA rodlet results in the axial movement of the BA capsule inside of the BA rodlet.

2. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 1 , wherein the plurality of bearing columns are configured to position the BA rodlet in a center of the capsule removal tunnel along the longitudinal axis.

3. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 1 , wherein the BA capsule removal module is configured to remove BA capsules from each BA rodlet of a plurality of BA rodlets submersed in a spent rod pool.

4. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 3 , and further comprising a control circuit, wherein the control circuit is configured to provide control commands to the BA capsule removal module from outside of the spent rod pool.

5. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 4 , wherein the control circuit is configured to position the BA capsule removal module relative to the BA rodlet.

6. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 4 , wherein the control circuit is configured to send a command to the BA capsule removal module, and wherein the command induces the electromagnetic flux in the BA capsule.

7. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 6 ,

wherein the BA capsule removal module is configured to communicate a feedback response to the control circuit, and

wherein the control circuit is configured to receive the feedback response from the BA capsule removal module and use the feedback response to modulate a current in the solenoid.

8. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 4 , wherein the control circuit is manually operated by a technician.

9. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 4 , wherein the control circuit is automatically operated by a processor, and wherein the processor automatically evaluates feedback responses from the BA capsule removal module.

10. The apparatus for removing irradiated burnable absorber (BA) capsules of claim 1 , and further comprising

a BA rodlet and

a BA capsule inside of the BA rodlet,

wherein the BA capsule comprises Cobalt-60 isotopes.
