Normally UF6 is evaporated from the solid using heated autoclaves and is distributed in gaseous form to the centrifuges by way of cascade header pipework.

Normally UF6 is evaporated from cylinders placed within autoclaves and is distributed in gaseous form to the entry point by way of cascade header pipework.

Chemical conversions (oxidation and reduction) are required at both ends of the separation cascade in order to provide for the reflux requirements at each end.

Because of the high inertial properties of diffusion cascades, any interruption in their operation, and especially their shutdown, leads to serious consequences.

The contactors employed in the separation cascade can be liquid-liquid exchange columns (such as pulsed columns with sieve plates) or liquid centrifugal contactors.

When the host proteolytic cascades are activated by the pathogens to their advantage, the disease becomes chronic, resulting in substantial loss of periodontal tissue and alveolar bone.

In the liquid-liquid chemical exchange process, immiscible liquid phases (aqueous and organic) are countercurrently contacted to give the cascading effect of thousands of separation stages.

Because an enrichment plant consists of many thousands of centrifuges arranged in cascades there are many kilometers of cascade header pipework, incorporating thousands of welds with a substantial amount of repetition of layout.

At the present, the most probable candidate is a T cell (T cell recetor genes, MHC genes), but other cell types (macrophages, granulocytes) can not be excluded as possible candidates for the expression of genetic features capable of initiating al allergic cascade.

The 'product' and 'tails' UF6 gaseous streams flowing from exit points are passed by way of cascade header pipework to either cold traps or to compression stations where the UF6 gas is liquefied prior to onward transfer into suitable containers for transportation or storage.

The 'product' and 'tails' UF6 gaseous streams flowing from the centrifuges are also passed by way of cascade header pipework to cold traps (operating at about 203 K (-70 oC)) where they are condensed prior to onward transfer into suitable containers for transportation or storage.

Flow in the tandem cascade was calculated with the standard and the RNG k-e models.

The reason for the smaller losses in the tandem cascade is the coupled calculation of the spiral casing.

The first stage was a separate analysis of the flow through the tandem cascade, the runner and the draft tube.

A numerical analysis of the flow in the tandem cascade, the runner and the draft tube was made in three stages.

With grid refinement the flow-energy losses decrease, especially in the tandem cascade and the runner, while in the draft tube the effect is small.

The computational domain for the tandem cascade is the region between two stay vanes and three guide vanes and between the hub and crown, but without runner blades.

The efficiency was the highest for a simultaneous calculation of the flow in the whole turbine, mainly due to the smaller flow-energy losses in the stay- and guide-vane cascades.
