Tsurusoken tried to recover simulated loose parts in a sodium pot, and conducted visualization tests with ultrasound and recovery tests with a prototype recovery device.

1. By pressing the recovery device from above, the tips of the device are transformed into a shape that matches the loose parts.

2. Tighten it from the outside and fix the loose parts.

Prototype loose part recovery device

(We devised it to be a simple and robust structure)

We gained basic knowledge about remote maintenance technology in opaque liquid sodium.
