In the described fuel production sequence, which is the final stage?

• A. Uranium oxide slurry
• B. Yellow cake
• C. Fuel pellets
• D. Fuel rods

Answer: (D)

In fuel fabrication, the pellets are the ceramic form of uranium dioxide that ultimately become the functional unit inside a reactor. After producing and processing UO2 into pellets, these pellets are sealed inside a corrosion-resistant cladding tube to form fuel rods. This encapsulated form is what is actually inserted into reactor cores, often grouped into assemblies. So, among the given stages, the final step is the creation of fuel rods, because that is the completed, self-contained unit ready for reactor use. The earlier items—yellowcake as the mined-concentrate, a uranium oxide slurry as an intermediate processing form, and the pellets themselves as an intermediate product—occur before the final rod form.
