But first, what is a nuclear fuel rod? It is a group of tubes made of zirconium alloy or stainless steel. Inside these sealed tubes are pellets made of enriched uranium stacked on top of one
another. Bundled together, these nuclear fuel rods are then used to form a nuclear fuel core.

So, are they safe to hold? The answer is no, not without special protection for your hands. This is because the pellets, as mentioned, are made of uranium which is radioactive according to Los Alamos National Laboratory's Chemistry Division. Meaning, nuclear fuel rods are radioactive. The Energy Information Administration also says they are even more radioactive after they are completely used up and ready to be replaced. Therefore, they are not safe enough to directly hold.
