The arrangement of centrifuges connected in parallel and in series
is termed a “cascade”. In a uranium enrichment plant several
cascades are operated in parallel to form an “operational unit”
producing one U235 assay. Various operational units form one

This is the process of removing the volatile fluorine component from
uranium hexafluoride to make stable uranium oxide (U3O8). URENCO
has chosen to use U3O8 as the long-term retrievable storage form of

The step taken in the nuclear fuel cycle that increases the
concentration of U235, relative to U238, in order to make uranium
usable as a fuel for light water reactors.

Enriched Uranium Product, i.e. UF6 enriched, typically, to between
3% and 5% U235 content.
Natural or reprocessed uranium, converted to UF6, and fed into the

Gas centrifugation is a uranium enrichment process which uses the
gas centrifuge to accelerate molecules so that particles of different
masses are physically separated along the radius of a rotating
container. This increases the proportion of the useful U235 isotope.

to increase the concentration of the fissionable U235 isotope.
Uranium hexafluoride that contains a lower concentration than the
natural concentration (0.711%) of the U235 isotope.
The facility managed by URENCO ChemPlants that will manage
the deconversion of tails to stable uranium oxide (U3O8). Currently
under construction at URENCO’s UK site in Capenhurst, UK, it
will consist of a number of associated storage, maintenance
and residue processing facilities to support URENCO’s long-term
strategy for the management of tails.

A fairly abundant metallic element. Approximately 993 of every
1,000 uranium atoms are U238. The remaining seven atoms are
U235 (0.711%), which is used in today’s nuclear power stations to
generate energy by fission.
All enrichment processes today work with gaseous material;
therefore uranium is converted to UF6.
