{0>The auxiliary systems, equipment and components for gaseous diffusion enrichment plants are the systems of plant needed to feed UF6 to the gaseous diffusion assembly, to link the individual assemblies to each other to form cascades (or stages) to allow for progressively higher enrichments and to extract the 'product' and 'tails' UF6 from the diffusion cascades.<}0{>Is-sistemi awżiljarji, it-tagħmir u l-komponenti għall-impjant imsaħħaħ għad-diffusjoni tal-gassijiet huma sistemi ta’ l-impjant meħtieġ għad-dħul tal-UF6 fl-assemblaġġ tad-diffusjoni tal-gassijiet, biex jgħaqqad l-assemblaġġi individwali ma’ xulxin biex jiffurmaw kaskati (jew stadji) biex jippermettu t-tisħiħ progressiv għoli u għal ħruġ tal-'Prodott' u 'truf'UF6 mill-kaskati tad-diffusjoni.<0} {0>Because of the high inertial properties of diffusion cascades, any interruption in their operation, and especially their shutdown, leads to serious consequences.<}0{>Minħabba l-proprjetajiet għolja ta’ inertia tal-kaskati tad-diffusjoni, kull interruzjoni fil-ħidma tagħhom, u b’mod speċjali l-għeluq tagħhom, u jwassal għal konsegwenzi.<0} {0>Therefore, a strict and constant maintenance of vacuum in all technological systems, automatic protection from accidents, and precise automated regulation of the gas flow is of importance in a gaseous diffusion plant.<}0{>Għaldaqstant, il-manutenzjoni stretta u kostanti tal-vacuum fis-sistemi kollha teknoloġiċi, il-protezzjoni awtomatika mill-aċċidenti, u regolamentazzjoni eżatta awtomata tal-kurrent tal-gass hija ta’ importanza fl-impjant tad-diffusjoni tal-gassijiet.<0} {0>All this leads to a need to equip the plant with a large number of special measuring, regulating and controlling systems.<}0{>Dan kollu jwassal għal ħtieġa għat-tagħmir ta’ l-impjant b’numru kbir tal-miżuri speċjali, sistemi li jirregolaw u li jikkontrollaw.<0}
