After enriching the uranium, it is chemically enriched into uranium dioxide, converted into small pellets, and placed inside cylindrical fuel pods. Using sophisticated technology, the pod is made of a metal called zirconium. The fuel rod is located in the heart of the reactor, preparing it for operation. Since converting zirconium to fuel pods is a very difficult and advanced thing to do, there are a few countries in the world that have access to this technology. Several other countries Import fuel rods to supply fuel for their nuclear reactors
