摘要： 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.

摘要： A first system for producing a high flux of neutrons for non-destructive testing includes a dense plasma focus device neutronically coupled to a subcritical or sub-prompt critical fission assembly. The dense plasma focus device is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission. A second system for producing a high flux of neutrons includes a gas-target neutron generator neutronically coupled to a subcritical or sub-prompt critical fission assembly. The gas-target neutron generator is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission.

摘要： In a method of producing isotopes in a light water power reactor, one or more targets within the reactor may be irradiated under a neutron flux to produce one or more isotopes. The targets may be assembled into one or more fuel bundles that are to be loaded in a core of the reactor at a given outage. Power operations in the reactor irradiate the fuel bundles so as to generate desired isotopes, such as one or more radioisotopes at a desired specific activity or stable isotopes at a desired concentration.

摘要： A nuclear-powered plant for systems of up to about 100 MWs with a confinement section where the reaction takes place in a core having a reactive thorium/uranium-233 composition, and where an external neutron source is used as a modulated neutron multiplier for the reactor core output. The core is housed in a containment structure that radiates thermal energy captured in a multiple-paths heat exchanger. The exchanger heat energy output is put to use in a conventional gas-to-water heat exchanger to produce commercial quality steam.

摘要： The invention pertains to a transport system for transporting containers or products within and along an essentially vertical tube with concurrent rotation of the containers on the axis of the tube. In order to facilitate simple construction despite conditions of limited space, it is proposed that the tube be designed as a vertical rotary tube, to which a rotatably retained worm sleeve is connected at the end of the transport path. Provided within the rotary tube are longitudinal guide grooves, in which dogs carried by the containers engage. These dogs also engage in the screw thread of the worm sleeve. On their upper and lower sides, the containers have couplings, e.g., an end toothing, which, during the transport of a group of adjoining containers, impart a rotary movement from container to container but also make possible a separation of one container from another in the direction of the axis of the tube. During a rotation of the rotary tube, the containers are successively rotated through by the worm sleeve, which can accommodate least one container. The transport system is especially suited for transporting silicon monocrystals, which are enclosed within the containers, through the heavy water tank of a research reactor for doping said silicon monocrystals by way neutron bombardment.
