Fuel fabrication

Definition

Fuel fabrication is the process of assembling nuclear fuel from enriched uranium or mixed oxide (MOX) materials into fuel assemblies used in nuclear reactors. This critical step in the nuclear fuel cycle ensures that the fuel meets specific design and safety requirements before being utilized in reactors for energy production.

5 Must Know Facts For Your Next Test

1. Fuel fabrication involves several key steps, including mixing, pelletizing, and assembling fuel into rods or assemblies that can be loaded into reactors.
2. Safety and quality control are paramount during fuel fabrication to ensure that the fuel will operate effectively within a reactor's specific conditions.
3. The most common type of fuel used in light-water reactors is uranium dioxide (UO2), while MOX fuel, which combines plutonium and uranium, is used in some advanced reactors.
4. The fabrication process typically takes place at specialized facilities designed to handle radioactive materials and minimize environmental impacts.
5. After the fuel has been used in a reactor, it becomes spent fuel and requires proper management and storage to prevent environmental contamination.
