- the figures for plutonium are the total amount of all plutonium isotopes.
- the figures for highly enriched uranium (HEU) are for the uranium 235 content of uranium enriched to above 20% of that isotope.
- low enriched uranium (LEU), natural uranium and depleted uranium cannot be used to make explosive devices. The published figures include these grades for the sake of completeness.
- for which Sellafield Ltd became the site licensee on 1 April 2008
