Process for the dissolution of plutonium or other radioactive elements from solid or liquid products and microwave-powered heating device for carrying out the process

摘要

Dissolving plutonium and/or other radioactive elements in an aqueous solution by means of heating using microwaves. According to the invention solid or liquid products containing plutonium and/or other radioactive elements are introduced into a receptacle 7 containing an acidic solution such as a nitric solution, the solution containing these products is then heated using microwaves by employing a housing 5 arranged in a leakproof vessel 1 which is supplied with microwaves by means of a coaxial cable or a waveguide 11 connected to the generator 9 situated outside the vessel. The solid products may be PuO2 or organic or inorganic radioactive waste such as gloves, cellulose products, ion exchange resins and the like. IMAGE
