US Patent:

6568879, May 27, 2003
Filed:

Aug 14, 2000
Appl. No.:

09/637005
Inventors:

Bruce J. Mincher - Idaho Falls ID 83404
Randy Dale Curry - Columbia MO 65203
Thomas E. Clevenger - Columbia MO 65201
Jeffry Golden - Laurel MD 20708
International Classification:

B09B 700
US Classification:

4051285, 210634, 40512825
Abstract:

A process of extracting halogenated organic compounds, and particularly PCBs, from soil, sediment, slurry, sludge and dehalogenating the compounds contacts a contaminated soil sample with an extraction medium of a mixture of an alkane and a water miscible alcohol. The organic compounds dissolve in the extraction medium which is separated from the soil by passing water upwardly through the soil. The extraction medium floats to the surface of the water and is separated. Thereafter, the extraction medium containing the halogenated organic contaminants is subjected to ionizing radiation to radiolytically dehalogenate the compounds.

C22B 3/00
US Classification:

210638, 422159
Abstract:

A method of reducing radiotoxicity in an aqueous acidic solution is disclosed. The method comprises oxidizing actinide ions in an aqueous acidic solution to hexavalent actinide ions. An organic phase comprising at least one organophosphorus extractant is added to the aqueous acidic solution. The at least one organophosphorus extractant comprises a compound having from one oxygen atom to three oxygen atoms bonded to a phosphorus atom and having one of the oxygen atoms bonded to the phosphorus atom through a phosphorus-oxygen double bond. Complexes are formed between the hexavalent actinide ions and the at least one organophosphorus extractant. The complexes are separated from the aqueous acidic solution. An additional method and a reaction system for removing actinides from an aqueous acidic solution are also disclosed.

International Classification:

C22B 60/00
US Classification:

75396
Abstract:

Methods of producing plutonium-238 are disclosed. One method includes dissolving neptunium-237 in a nitric acid solution to produce a neptunium target solution, subjecting the neptunium target solution to neutron radiation to produce plutonium-238, and removing the plutonium-238 from the neptunium target solution. A second method includes exposing a solution of neptunium-237 to neutron radiation to produce plutonium-238, complexing the plutonium-238 with an organophosphorus compound, and separating the plutonium-238/organophosphorus compound complex from the solution of neptunium-237. A third method includes dissolving neptunium-237 to form a neptunium-237 target solution, exposing the neptunium-237 to thermal neutrons to produce plutonium-238, utilizing an organophosphorus compound to complex the plutonium-238 and the organophosphorus compound, extracting the plutonium-238/organophosphorus compound complex from the irradiated neptunium target solution, and recovering the plutonium-238.

US Patent:

57992576, Aug 25, 1998
Filed:

Jun 29, 1995
Appl. No.:

8/496385
Inventors:

David H. Meikrantz - Idaho Falls ID
Bruce J. Mincher - Shelley ID
Rodney E. Arbon - Blackfoot ID
Assignee:

Lockheed Martin Idaho Technologies Company - Idaho Falls ID
International Classification:

A62D 300
C07B 3506
US Classification:

588200
Abstract:

The invention is a process for the in-situ destruction of polychlorinated biphenyl (PCB) compounds in transformer oils and transformers. These compounds are broken down selectively by irradiation of the object or mixture using spent nuclear fuel or any isotopic source of high energy gamma radiation. For example, the level of applied dose required to decompose 400 ppm of polychlorinated biphenyl in transformer oil to less than 50 ppm is 500 kilogray. Destruction of polychlorinated biphenyls to levels of less than 50 ppm renders the transformer oil or transformer non-PCB contaminated under current regulations. Therefore, this process can be used to treat PCB contaminated oil and equipment to minimize or eliminate the generation of PCB hazardous waste.
