What material is used to make fuel rods?

Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. Typically more than 200 of these rods are bundled together to form a fuel assembly.

What are the fuel rods in a nuclear reactor made of?

A long, slender, zirconium metal tube containing pellets of fissionable material, which provide fuel for nuclear reactors.

Where are nuclear fuel rods made?

Uranium mines operate in many countries, but more than 85\% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia. Historically, conventional mines (e.g. open pit or underground) were the main source of uranium.

Does a fuel rod contain uranium?

Commercial used nuclear fuel is a solid The fuel is made up of metal fuel rods that contain small ceramic pellets of enriched uranium oxide. The fuel rods are combined into tall assemblies that are then placed into the reactor. It’s a solid when it goes into the reactor and a solid when it comes out.

How many uranium pellets are in a fuel rod?

Modern reactor cores in pressurized-water reactors (PWRs) and boiling-water reactors (BWRs) may contain up to 10 million pellets, stacked in the fuel rods that form fuel assemblies.

How heavy is a uranium fuel rod?

185 kilograms
RBMK fuel rods are about 3.65 metres long, and a set of 18 forms a fuel bundle about 8 cm diameter. Two bundles are joined together and capped at either end by a top and bottom nozzle, to form a fuel assembly with an overall length of about 10 metres, weighing 185 kilograms.
