| Problem to be solved: |
Precisely measure the mass of uranium bar which need to be removed from its environment and reintroduce with a force of insertion strictly equivalent to the extraction force. |
| |
|
| Constraints: |
Accuracy level of go & back elasticity curve. No hysteresis. Highly radioactive environment. |
| |
|
| Solution: |
Studying an accordion bellows spring geometry. |
| |
|
| Borrelly added value: |
Completely manufactured in the mass from CuBe2 this bellows designed entirely by Borrelly provides a safe and sustainable solution. |
