Abstract

The disclosure describes an apparatus for performing at least two successive chemical reactions in the same container. In order to successively carry out several chemical reactions in the same container (10), e.g. dosing uranium in the presence of plutonium and fission products, the container is placed in a working station above which issue tubes (16, 20) for supplying the products necessary for the reactions. When a product has to be introduced, a computer controls the descent of the corresponding tube. When the product may react inopportunely if it drops into the container (10) outside the time intended for this purpose, the lower end of the product supply tube (16) is automatically laterally displaced with respect to the container, when the tube is in the top position, e.g. by the cooperation of a pawl (102) with a slot (100) forming a cam.

Claims12

Dependent claims

Apparatus for performing several successive chemical reactions within a single container, comprising:

a working station adapted to receive the container,
at least two chemical reactant arrival tubes, each tube having a first end issuing above the working station and an opposite, second end immersed in a distribution drum containing a chemical reactant,
control means for moving the first end of each tube between an upper, inactive position and a lower, reactant injection position,
cam means for displacing the first end of at least one of said tubes in a lateral direction with respect to said container upon actuation of said control means such that the first end is placed in the container when the said at least one tube is in the lower, reactant injection position, and is laterally displaced by the cam means with respect to the container upon movement of the said at least one tube toward the upper, inactive position by the control means.
