US Patent:

20120065453, Mar 15, 2012

Filed:

Feb 22, 2011

Appl. No.:

13/031672

Inventors:

Mark P.S. Krekeler - Hamilton OH, US
Stephen C. Elmore - Stafford VA, US

International Classification:

G21F 9/12
C09K 3/00

US Classification:

588 20, 252184, 588 1

Abstract:

A radioactive containment composition may be created for containing radionuclides from a radioactive material by mixing a clay mineral with water. This mixture may form an aqueous clay suspension, which in turn can be refined by filtering to remove coarse material. The aqueous clay suspension may be applied to a radioactive material, allowing the radionuclides to be exchanged with cations in the aqueous clay suspension. The resulting aqueous slurry may be collected, heated and analyzed.

Abstract:

A radioactive material sequestration system may include a radionuclide containment composition dispenser and a sorption based media container. The radionuclide containment composition dispenser may be configured for holding a radionuclide containment composition and be capable of dispensing the radionuclide containment composition to remove radionuclides from a radioactive material. The radionuclide containment composition is a mixture of a clay mineral and water. The sorption based media container may be configured for holding a sorption based media; receiving dispensed radionuclide containment composition; and sequestering the radionuclides. The radioactive material sequestration system may also include a probe.
