Pomožni sistemi, oprema in sestavni deli za obrat za izotopsko obogatitev s plinskimi centrifugami so sistemi za dovajanje UF6 centrifugam, za medsebojno povezovanje posameznih centrifug, tako da tvorijo kaskade (ali stopnje) in tako omogočajo postopno vse višje stopnje obogatitve, in za odvajanje obogatenega in osiromašenega proizvoda UF6 iz centrifug skupaj z opremo za pogon centrifug ali za krmiljenje obrata.
The auxiliary systems, equipment and components for a gas centrifuge enrichment plant are the systems of plant needed to feed UF6 to the centrifuges, to link the individual centrifuges to each other to form cascades (or stages) to allow for progressively higher enrichments and to extract the 'product' and 'tails' UF6 from the centrifuges, together with the equipment required to drive the centrifuges or to control the plant.
