Appendix G to Part 110 - Illustrative List of Plasma Separation
Enrichment Plant Equipment and Components Under NRC Export
Licensing Authority Note:
In the plasma separation process, a plasma of uranium ions
passes through an electric field tuned to the 235U ion resonance
frequency so that they preferentially absorb energy and increase
the diameter of their corkscrew-like orbits. Ions with a
large-diameter path are trapped to produce a product enriched in
235U. The plasma, made by ionizing uranium vapor, is contained in a
vacuum chamber with a high-strength magnetic field produced by a
superconducting magnet. The main technological systems of the
process include the uranium plasma generation system, the separator
module with superconducting magnet, and metal removal systems for
the collection of “product” and “tails.”
(1) Microwave power sources and antennae.
Especially designed or prepared microwave power sources and
antennae for producing or accelerating ions having the following
characteristics: Greater than 30 GHz frequency and greater than 50
kW mean power output for ion production.
(2) Ion excitation coils.
Especially designed or prepared radio frequency ion excitation
coils for frequencies of more than 100 kHz and capable of handling
more than 40 kW mean power.
(3) Uranium plasma generation systems.
Especially designed or prepared systems for the generation of
uranium plasma for use in plasma separation plants.
(4) Uranium metal “product” and “tails” collector
assemblies.
Especially designed or prepared “product” and “tails” collector
assemblies for uranium metal in solid form. These collector
assemblies are made of, or protected by, materials resistant to the
heat and corrosion of uranium metal vapor, such as yttria-coated
graphite or tantalum.
(5) Separator module housings.
Especially designed or prepared cylindrical vessels for use in
plasma separation enrichment plants for containing the uranium
plasma source, radio-frequency drive coil, and the “product” and
“tails” collectors.
These housings have a multiplicity of ports for electrical
feed-throughs, diffusion pump connections, and instrumentation
diagnostics and monitoring. They have provisions for opening and
closure to allow for refurbishment of internal components and are
constructed of a suitable non-magnetic material such as stainless
steel.
(6) Any other components especially designed or prepared for use
in a plasma separation enrichment plant or in any of the components
described in this appendix.
