Radiological Safety Training for Uranium Facilities
Module 102 The Nuclear Fuel Cycle
The methods used to enrich uranium include:
a.
Gaseous Diffusion
Gaseous diffusion is based on principles of gas laws. The UF6 gas is
forced through converters by large compressors. The converters contain
many tubes made of a special barrier material that is porous. The 235UF6
molecules are lighter than the 238UF6 molecules and bounce against the
porous barrier more frequently. The 235UF6 has a greater chance of
passing through the barrier, resulting in a slightly richer 235U content. It
may take as many as a thousand passes to obtain the desired degree of
enrichment.
b.
Laser Processes
The Atomic Vaporization Laser Isotope Separation (AVLIS) involves
vaporization, selective ionization of one isotope, and subsequent electrical
separation. Currently, no DOE production plants exist which use this
technology.
c.
Nozzle Separation
The nozzle separation process is based on the different speeds of 235U
and 238U compounds when they are injected through a nozzle into a small
chamber.
