To prepare uranium for use in a nuclear reactor, it undergoes the steps of mining and milling, conversion,
enrichment and fuel fabrication. These steps make up the 'front end' of the nuclear fuel cycle.
After uranium has spent about three years in a reactor to produce electricity, the used fuel may undergo a
further series of steps including temporary storage, reprocessing, and recycling before eventual disposal as
waste. Collectively these steps are known as the 'back end' of the fuel cycle.
These are the various steps that together make up the entire Nuclear Fuel Cycle:
