Abstract: A nuclear reactor including a core area; a plurality of detachable reactor modules at least partly arranged in the core area, each detachable reactor module being detachable from the core area for replacement without interference with other reactor modules, and including a containment; a loop arranged in the containment and having a nuclear fuel liquid; a pump for circulating the liquid in the loop; and a heat exchanger for exchanging heat between the liquid and a secondary heat system.

Abstract: A nuclear reactor circuit contains nuclear fuel-containing molten salt in a channel which is substantially vertically arranged and provides an up-down passage. A modular reactor has removable, individual molten salt nuclear circuits. The channel of one circuit contains a non-critical amount of nuclear material, but the channels together create the critical zone of the reactor core. A method of operating a modular nuclear reactor circuit and a nuclear reactor include the use of the circuits.

Abstract: Disclosed is a process for the production of platinum isotopes from iridium comprising the steps of providing a mixture, preferably an atomic dispersion of a carrier material such as Al and iridium (Ir), subjecting the carrier material-Ir mixture to a neutron flux to thereby generate an irradiated carrier material-Ir mixture comprising platinum (Pt) isotopes, isolating Pt isotopes from the irradiated carrier material-Ir mixture.

Abstract: The present invention relates to use of a chelating compound for chromatographic separation of rare earth elements, actinides, and/or s-, p- and d-block metals, and to a method of chromatographic separation of chelates of rare earth elements, actinides and/or s-, p- and d-block metals from a mixture of at least two metal ions.

Abstract: Method and apparatus for the generation and isolation of radionuclides comprising the steps of providing a radioactive gas, allowing the radioactive gas to decay to form charged daughter radionuclides, providing a liquid in contact with the gas, subjecting the charged daughter radionuclides (16) to an electric field between two electrodes (5,6), thereby absorbing the charged daughter radionuclides (16) in the liquid, and isolating the liquid comprising the charged daughter radionuclides (16).

Abstract: A method for the manufacture of Actinium-225 from a Radium-226 containing material. Radium-226 containing starting target material is shielded with a thermal neutron absorption shield and is subjected to neutron irradiation from a moderated nuclear reactor. Radium-226 is thereby converted into Radium-225 to provide a Radium-225-containing material. The Radium-225 in the Radium-225 containing material is allowed to decay into Actinium-225, and the Actinium-225 is isolated from the Radium-225 containing material. The neutron absorption shield shields the starting target material from neutrons having an energy in the range of 20 eV to 1000 eV.

Abstract: The invention relates to a nuclear reactor circuit that is capable of containing nuclear fuel-containing molten salt in a channel which is substantially vertically arranged and provides an up-down passage. The circuits can be used to build a modular reactor from removable, individual molten salt nuclear circuits one part of which (‘the channel’) has been placed in a critical configuration, wherein the channel contains a non-critical amount of nuclear material, but the channels together create the critical zone of the reactor core. The invention further relates to methods of operating a modular nuclear reactor circuit and a nuclear reactor.

Abstract: Method for the manufacture of Radium-225-containing material from Radium-226-containing materials by subjecting a starting material containing Radium-226 to neutron irradiation from a nuclear reactor to convert 226Ra into Radium-225 to provide a Radium-225-containing material, characterised in that the neutron irradiation of Radium-226-containing starting material is performed in a moderated nuclear reactor; and the Radium-226-containing starting material is shielded with a thermal neutron absorption shield.
