Nuclear energy has three main phases.

When people say “nuclear lifecycle,” they mean everything from mining uranium to disposing of waste. A campus might host some or all of these stages. Here’s how the flow works:


01

Mining & Milling

Uranium ore is extracted and processed into “yellowcake” — a concentrated uranium powder. This step is a possible campus function but doesn’t have to be on-site.

02

Conversion

Yellowcake is chemically transformed into uranium hexafluoride (UF₆), a gas that can be enriched. This is the step Tooele County has received specific interest about.

03

Enrichment

The concentration of uranium-235 is increased to make reactor-grade fuel. Most commercial reactors use 3–5% enriched uranium; advanced reactors need higher concentrations.

04

Fuel Fabrication 

Enriched uranium is manufactured into fuel pellets and assemblies — the physical form that goes into a reactor.

05

Reactor Operations 

Fuel is used to generate electricity or heat. Modern campuses may host small modular reactors (SMRs) or microreactors rather than large traditional reactors.

06

Storage & Reprocessing

Used fuel is stored in cooled pools, then dry casks. Reprocessing can recover usable uranium and plutonium for reuse — a key DOE focus area.

07

Waste Management & Disposal

The most sensitive step. Low-level waste goes to licensed disposal sites. High-level waste requires long-term deep-geologic solutions still being developed nationally.
