  • Publication number: 20120300890
    Abstract: 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.

  • Publication number: 20120300891
    Abstract: 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.

  • Publication number: 20120286164
    Abstract: 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.

  • Publication number: 20110096887
    Abstract: 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.
