Abstract: The present invention relates to a molten salt-metal reactor for implementing a micro-reactor, and more specifically, to a molten salt-metal reactor including a liquid metal nuclear fuel and a molten salt coolant, wherein the molten salt coolant is disposed in an upper portion of the liquid metal nuclear fuel such that the heat generated from the nuclear fuel is transferred to the molten salt coolant and cooled.

Abstract: Disclosed is a method of producing Tc-99m by using nuclear resonance fluorescence. More specifically, and a method of preparing Tc-99m by using nuclear resonance fluorescence includes irradiating a ground-state Tc-99 nucleus with a photon beam, thereby causing a nuclear transmutation to proceed such that the nucleus excited to high energy and then undergoes a transition to Tc-99m.

Abstract: Disclosed herein is a reactor including a reactor vessel and a containment vessel configured to surround the reactor vessel. The containment vessel includes a thermal radiation shield disposed on an inner wall, and a gap between the reactor vessel and the containment vessel is in an atmospheric pressure and air atmosphere state.

Abstract: The invention relates to a method and a system for producing radioisotopes, and specifically, the method and system for producing radioisotopes including generating one or more among actinium-225 (225Ac), thorium-227 (227Th), and radium-226 (226Ra) by irradiating a natural thorium target including thorium-232 (232Th) with braking radiation or an accelerated electron beam.

Abstract: Disclosed is an apparatus for extracting multiple laser Compton scattering (“LCS”) photon beams using a laser Compton scattering reaction, the apparatus including: a linear accelerator for accelerating an electron beam; and an LCS gamma ray generation module including an LCS gamma ray generator for irradiating a target with an LCS gamma ray generated by emitting laser light to an electron beam released from the linear accelerator and a bending magnet for adjusting a direction of the electron beam passed through the LCS gamma ray generator, wherein at least two LCS gamma ray generation modules are sequentially arranged to form a closed loop together with the linear accelerator.
