Seasonally Adjusted Annual Rate. Usually this is arrived at by simple multiplication (e.g. multiplying a monthly rate, after seasonal adjustment, by 12), but sometimes it involves compounding.

Uranium units

When quantities of uranium are being measured, it is the total weight of atoms of the fissile isotope that most matters. The ratio of the actual weight to this key measure varies according to the isotope blend and the chemical compound containing the uranium.

Isotopes

  • U-235 – the fissile isotope.
  • U-238 – the common isotope, not of primary relevance in most reactor fuel.
  • Naturally occurring uranium is about 0.7% U-235.
  • LEU – Low Enriched Uranium, is about 4% U-235; suitable for reactor fuel.
  • HEU – Highly Enriched Uranium, is about 97% U-235, suitable for weapons.

Compounds

  • Metal – Unless otherwise qualified, “uranium” in most reporting means uranium metal, at the naturally occurring isotope mix. Of course neither deposits in the ground nor reactor fuel is bare metal, but amounts of each are typically quoted in tons of natural uranium metal equivalent.
  • Uranium hexaflouride – the high-speed gas centrifuges used to enrich uranium work with UFl6. UFl6 is not directly relevant to reactors.
  • Yellowcake – A key output of mines is a mixture of uranium oxides, mainly U3O8, which is usually yellow or brown and called yellowcake.

Prices

  • In the US prices are quoted as dollars per pound of U3O8.

YOY

Year over year, i.e. change in one year's time.
