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.

The present invention relates to a nuclear target (1), a method for inducing a nuclear reaction and a device capable of inducing nuclear reactions. According to the present invention, the nuclear target (1) is equipped with a hollow (12) into which projectile particles (3) are deposited. In the hollow (12), the projectile particles (3) interact with precursors (21 and/or 22 and/or 23), or projectile particles (3) are elastically scattered on isotopes (4). The nuclear target (1), method, or the device thus provides a more efficient induction of nuclear reactions and provides a higher yield of radioisotope production. In another embodiment, the nuclear target (1) can be used as a means used to nuclear waste transmutation, or as a means of sustainable exothermic nuclear reactions.

Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

A method of radioactive isotopes production in Fast Neutron Nuclear Reactor. The targets for radio nuclides production are being placed in the radiation assembly between the plumbs made of neutrons slowing materials, and the radiation assembly is being placed in the side screen of Fast Neutron Nuclear Reactor. The assemblies not containing nuclear fuel are placed around the radiation assembly. Fast neutrons are passed through the neutrons slowing material and then the slowed neutrons are passed through the radiated material (targets) in radiation assembly. The radio isotopes production is done simultaneously in radiation assembly and surrounding assemblies with content of steel less than 50%. The targets of radiation assembly have the absorption cross-section over 1 barn with neutrons energy less than 0.1 MeV. The targets of assemblies surrounding the radiation assembly have the neutrons absorption cross-section less than 1 barn with neutrons energy over 0.1 MeV.

A target well of a target delivery assembly for use in an irradiation system operative to allow irradiation of a radioisotope target via a vessel penetration of a fission reactor. The target well includes an outer tube and an inner tube disposed therein so that an annulus is formed therebetween. The target is positioned in the inner tube during irradiation. At least one flow channel extends between a bottom end of the outer tube and a bottom end of the inner tube. An elevation piston is slidably disposed within the inner tube to elevate the target, the elevation piston including a one-way check valve allowing flow in a downward direction and preventing flow in an upward direction.
