A hybrid nuclear reactor that is operable to produce a medical isotope includes an ion source operable to produce an ion beam from a gas, a target chamber including a target that interacts with the ion beam to produce neutrons, and an activation cell positioned proximate the target chamber and including a parent material that interacts with the neutrons to produce the medical isotope via a fission reaction. An attenuator is positioned proximate the activation cell and selected to maintain the fission reaction at a subcritical level, a reflector is positioned proximate the target chamber and selected to reflect neutrons toward the activation cell, and a moderator substantially surrounds the activation cell, the attenuator, and the reflector.

Device and method for producing medical isotopes

A nuclear reaction generator includes a chamber configured to contain a gas and including a target. The nuclear reaction generator also includes a filament provided inside the chamber and a voltage source configured to apply a first positive voltage to the filament relative to the chamber. The first positive voltage is configured to heat the filament to a temperature at which thermionic emission occurs and a plurality of thermions are generated, and the plurality of thermions is configured to ionize the gas to generate positive ions in the chamber. The target is configured such that nuclear reactions occur when the positive ions interact with the target.

Ion source and neutron generator

A sublimation/distillation apparatus including a crucible with an open end, a heating device thermally coupled to the crucible, an actively cooled collection substrate disposed above the open end of the crucible, and a vacuum chamber housing the crucible, the heating device, and the actively cooled collection substrate.

Separation of rare earth elements

A method for purifying lutetium includes providing a solid composition comprising ytterbium and lutetium and subliming or distilling ytterbium from the solid composition at a temperature of about 1196° C. to about 3000° C. to leave a lutetium composition comprising a higher weight percentage of lutetium than was present in the solid composition.

A reactor that is operable to produce an isotope includes a region for containing a controlled nuclear fission reaction, the region segmented into a plurality of independent compartments, each of the compartments for containing a parent material in an aqueous solution that interacts with neutrons to produce the isotope via a fission reaction. Also provided are methods of producing an isotope using the same.

Segmented reaction chamber for radioisotope production

An aqueous assembly has a negative coefficient of reactivity with a magnitude. The aqueous assembly includes a vessel and an aqueous solution, with a fissile solute, supported in the vessel. A reactivity stabilizer is disposed within the aqueous solution to reduce the magnitude of the negative coefficient of reactivity of the aqueous assembly during operation of the aqueous assembly.

Aqueous assembly and control method

An apparatus for generating medical isotopes provides an annular fissile solution vessel surrounding a neutron generator. The annular fissile solution vessel provides for good capture of the emitted neutrons and a geometry that provides enhanced stability in an aqueous reactor. A neutron multiplier and/or a neutron moderator may be used to improve the efficiency and control the criticality of the reaction in the annular fissile solution vessel.

Apparatus and method for generating medical isotopes

Provided are methods to separate an isotope from a first solution including uranium. The methods may include (a) cleaning the first solution to form a second solution including the uranium and a third solution including the isotope; (b) oxidizing the third solution to form an oxidized isotope; and (c) separating the oxidized isotope.

Methods of separating medical isotopes from uranium solutions

A hybrid nuclear reactor for producing a medical isotope includes an ion source for producing an ion beam from a gas, a target chamber including a target that interacts with the ion beam to produce neutrons, and an activation cell positioned proximate the target chamber and including a parent material that interacts with the neutrons to produce the medical isotope via a fission reaction.

An apparatus for inspecting the contents of a cargo container includes a neutron source having an ion source configured to provide deuterium or tritium ions and an accelerator configured to accelerate the ions toward a target having at least one of deuterium or tritium. The apparatus further includes a radiation detector where the neutron source is configured to deliver a neutron flux into the container and the radiation detector is configured to detect radiation exiting the container subsequent to the delivery of the neutron flux into the container.
