Abstract
A reactor (1) for hydrolysis of uranium hexafluoride comprises a tubular injector (9) comprising first (11), second (13) and third (15) concentric fluid circulation ducts intended to be connected respectively with a source of UF6, a source of inert gas and a source of water vapor. The tubular injector (9) is obtained by additive manufacturing.
Claims9
A uranium hexafluoride hydrolysis reactor comprising:
- a hydrolysis chamber, comprising a wall delimiting an internal volume;
- and
- a tubular injector comprising first, second and third concentric fluid circulation ducts, the tubular injector being mounted through the wall of the hydrolysis chamber and presenting an inner end located in the internal volume and an outer end located outside the internal volume;
- the first, second and third ducts present at the inner end first, second and third internal openings respectively, opening into the internal volume;
- the tubular injector includes, at the outer end, first, second and third fittings fluidically connected respectively to the first, second and third ducts and configured to be connected respectively with a source of UF6, a source of inert gas and a source of water vapor;
- the tubular injector being obtained by additive manufacturing,
- wherein the first, second, and third ducts at the outer end extend according to a longitudinal direction, the first fitting extending longitudinally, the second and third fittings each forming an angle of between 30° and 90° with the longitudinal direction;
- wherein the second and third fittings are located at substantially a same level along the longitudinal direction.
