Abstract

A pressurized electrochemical bulk-process method & apparatus, adapted to real-time tracking and adjustment of electro-hydraulic parameters, comprising a high-pressure reaction chamber of the type of a horizontal cylindrical electrolytic cell, whose zirconium walls constitute one electrode in contact with an electrolytic solvent containing the target material to be processed. The other electrode is a thin vertical zirconium disk partially submerged in the electrolyte, which fills less than half of the chamber. Because the electrolyte's resistance is not constant, the current cannot be controlled merely by adjusting the voltage in the 60-cycle AC current; instead, the current amperage must be monitored in real time and the voltage either lowered in response to sharp amperage increases in order to keep the cell's temperature (and hence its pressure) below the safety limits at which the disk-shaped Teflon end-gaskets sealing the cylinder's ends will rupture, or else increased, during normal operation, to compensate for decreases in current caused by various reactions occurring in the electrolyte.

Dependent claims

An apparatus for aneutronic bulk-process transmutation of at least one selected chemical element, in macroscopic amounts, into bulk amounts of at least one other species of chemical element not previously present, by utilization of a relatively low-energy electrochemical process, comprising:

(a) a horizontally-positioned cylindrical reaction chamber comprised of a length of zirconium piping.
(b) disk-shaped Teflon gaskets adapted to seal both ends of said chamber;
(c) an insulated zirconium rod-shaped conductor, centrally penetrating said gaskets and positioned axially along the central axis of rotational symmetry of said piping and adapted to carry external electrical current to both
(d) a central relatively thin vertical disk-shaped zirconium electrode positioned perpendicularly to said axis of symmetry and extending its circular edges to within a pre-selected small distance of the cylindrical walls of said piping, as well as
(e) thick stainless-steel end-plates, positioned apart but held in contractive tension by strong stainless steel bolts parallel to said axis, adapted to hold said gaskets firmly against the punctured-disk-shaped ends of said piping, with sufficient tensile strength to convert the apparatus into a high-pressure processing electrolytic cell when an electrolytic solvent liquid containing target materials for processing is introduced into said cylindrical reaction chamber in sufficient quantity for said liquid to be in contact with at least the lower portion of said vertical disk electrode as well as the lower portion of the containing cylindrically shaped wall-electrode;
(f) a high-pressure port by means of which a selected amount of said liquid may be introduced into said chamber and sealed therein prior to electrolytic processing;
(g) externally visible thermometric monitoring means permitting said chamber's temperature to be monitored visually during processing;
(h) external 60-cycle alternating current supply means,
(i) means for electrically connecting said disk-electrode and said chamber walls through said electrolytic fluid so as to constitute an electrolytic cell;
and
(j) means for real-time monitoring of both current amperage and voltage flowing through said electrolytic cell during processing;
and
(k) means allowing an operator to make real-time adjustments of said voltage in order to keep said amperage from raising said liquid's temperature to a point wherein the resultant fluid pressure poses a risk of rupture to said gaskets while simultaneously adapting to current decreases caused by variations in the electrolyte's resistance arising from reactions of the material being processed.
