  • Apparatus and method for generating medical isotopes
    Patent number: 11238999
    Abstract: 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.
    Type: Grant
    Filed: June 7, 2019
    Date of Patent: February 1, 2022
    Assignees: Wisconsin Alumni Research Foundation, SHINE Medical Technologies, Inc.
    Inventors: Gregory Richard Piefer, Thad Alexander Heltemes, Eric Nicholas Van Abel, Ross Francis Radel
