Isotope separation apparatus and process

摘要

An apparatus and process are disclosed for separation of isotopes by gaseous diffusion. The apparatus comprises at least one assembly of microporous capillary tubes having a hydraulic diameter below 0.5 cm, an average pore radius below 200 ANGSTROM , a thickness between 20 and 500 microns, a length of at least 25 cm, a porosity between 10 and 60% and a permeability to air between 10.10-7 and 100.10-7 mole/cm/2/min/cm of mercury. The tubes are made from an inorganic material and have a circular, square or rectangualr cross-section.
