All-Metal Inductive Sensors Ensure Reliable Detection in Nuclear Reactor Core

Pressurized-water reactors, operating at a Swiss nuclear power-plant, utilize fuel rods containing radioactive material to produce energy. During operation, bundles of rods are immersed in water; a purpose-built grab removes them when the fuel is spent. Contrinex all-metal inductive sensors detect the presence of a bundle in the grab and confirm that the grab is…
