Liquid metal reactor and method for treating materials in a liquid metal reactor
First Claim
1. A method for treating an article that includes a radioactive material, the method including the steps of:
- (a) loading the article into a containment area defined in a treatment vessel;
(b) while the article is being held in the containment area, tilting the treatment vessel from a loading position to a treatment position to place the article in contact with a liquid reactant metal in the treatment vessel to decompose the radioactive material in the article into radioactive material decomposition constituents dispersed in the liquid reactant metal;
(c) producing a storage mixture including the radioactive material decomposition constituents dispersed in the liquid reactant metal together with radioactive emission control materials, the radioactive emission control materials being present in the storage mixture in an effective ratio with radioactive material decomposition constituents in the storage mixture to limit radiation emissions from the storage mixture; and
(d) cooling the storage mixture in one or more molds to form a solidified storage product for the radioactive material decomposition constituents.

Abstract
A target material (60) to be treated in a liquid reactant metal is loaded into a containment area defined within a liquid reactant metal treatment vessel (11). The containment area is then placed below the level (L) of the liquid reactant metal in the treatment vessel (11). This places the target material (60) in contact with the liquid reactant metal and allows the desired reactions to occur. Reaction products are then removed from the treatment vessel (11). Placing the containment area below the level (L) of liquid reactant metal in the treatment vessel (11) may be accomplished by pivoting the vessel from a loading position to a treating position to shift the level of liquid reactant metal in the vessel.

7. A method of treating a target material in a liquid reactant metal, the method including the steps of:
-
(a) loading a target material into a containment area defined in a treatment vessel and holding the target material in the containment area, the containment area being defined within a boundary separating the containment area from the remainder of the volume of the treatment vessel; (b) with the target material held in the containment area, tilting the treatment vessel to a treatment position to change a level of a liquid reactant metal in the treatment vessel so as to place at least a portion of the containment area below the liquid reactant metal in the treatment vessel and thereby place the target material in contact with the liquid reactant metal; and (c) removing reaction products from the treatment vessel while the liquid reactant metal is maintained in a liquid state.

8. A method of treating a target material in a liquid reactant metal, the method including the steps of:
-
(a) containing a volume of liquid reactant metal in a treatment vessel; (b) while containing the liquid reactant metal in the treatment vessel, loading a target material into a position in the treatment vessel in which the target material is contained out of contact with the liquid reactant metal in the treatment vessel; (c) tilting the treatment vessel to place the target material in contact with the liquid reactant metal; and (d) removing reaction products from the treatment vessel. - View Dependent Claims (9, 10, 11, 12)
