Process and apparatus for classifying, segregating and isolating radioactive wastes

Details

Inventors: Manchak, Jr., Frank;
Assignee:
Primary Examiner: Locker; Howard J.
Assistant Examiner:
Attorney, Agent or Firm: Roth & Goldman

Low-level radioactive wastes and the like are identified by composition and segregated based on specific contaminants identified. The separated wastes are subsequently encapsulated in a centrifugal process prior to disposal. The wastes advantageously are subjected to heat prior to classification in order to remove any volatiles and hydrocarbons present.

DETAILED DESCRIPTION It is an object of present invention to provide a process of classifying, segregating and isolating radioactive wastes, and particularly mixed, low-level radioactive wastes, and to provide an apparatus for performing the method.
This and other objects are achieved according to the present invention by removing any volatiles and hydrocarbons from mixed low-level radioactive wastes and the like to be treated, identifying the composition of that portion of the wastes from which any volatiles and hydrocarbons have been removed by detecting predetermined specific contaminants in the wastes, and separating the identified wastes as a function of specific contaminants detected.
The separated wastes then can be isolated as appropriate.
The volatiles and hydrocarbons advantageously are stripped by being subjected to heat in a reactor vessel.
According to a particularly advantageous feature of the invention, the separated wastes are isolated in a centrifuge either by filling with the wastes a previously formed barrier constructed from a shielding material, or by mixing the waste with a shielding material.
