Change of the External Flows of a Separating Cascade to Shorten the Duration of a Transient Process

  • Published:
Atomic Energy Aims and scope

A transient process is studied for the example of obtaining in a cascade of gas centrifuges germanium enriched in 72Ge to 50%. The nature of the effect of the cascade flows on the concentration dynamics of the isotopes and duration of the transient process is determined. The conditions under which the accumulation of the desired isotope in the cascade is accelerated and the duration of the transient process is decreased are shown.
