This invention relates to a method for preparing an ultrathin 4π fission source based on a graphene substrate, belonging to the field of fission source preparation. The method involves preparing a graphene-toughened carbon film, growing graphene of a predetermined thickness on the film, and transferring the resulting substrate material. Fissionable material is then transferred onto the graphene substrate using a combination of solution drying and vacuum self-transfer technology, resulting in an ultrathin fission source capable of emitting fission fragments in the 4π direction. By transferring fission nuclides to a nanometer-thick graphene substrate, the fission products released from the fission source are emitted in the 4π direction, and the average energy loss of the fission fragments penetrating the substrate is far less than their own kinetic energy. This yields a high-quality fission source with low energy loss and minimal self-absorption, achieving efficient and stable preparation of an ultrathin 4π fission source, providing a relatively "perfect" fission source for fission physics experiments or related detector calibration.

This utility model relates to the field of mountain blasting technology and discloses a controlled mass fission release device for high-pressure gas in mountain blasting. It includes a cylinder with a cavity, an excitation device, and a nozzle. The cylinder has a pressure release mechanism located within the cavity to divide the cavity into a liquid storage chamber and a gas jet chamber with a nozzle. The excitation device is located in the liquid storage chamber and is used to heat the liquid gas. The cylinder is connected to a mounting ring located at the nozzle and has an axial insertion through-hole, an axially extending annular limiting groove surrounding the axial insertion through-hole, and an installation / removal guide groove extending axially along the mounting ring to connect with the annular limiting groove. The nozzle is inserted into the axial insertion through-hole, with the nozzle inlet communicating with the nozzle. The nozzle has an axial limiting block that slides into the annular limiting groove along the installation / removal guide groove and is spaced apart from the installation / removal guide groove circumferentially along the axial insertion through-hole. The axial limiting block is connected to the mounting ring by a locking element. The convenient installation and removal of the nozzle within the cylinder facilitates maintenance, thereby reducing maintenance costs.

An anti-proliferation technique is disclosed to reduce the likelihood of nuclear proliferation due to the use fissionable fuel salts. The technique includes doping the fuel salt with one or more elements (referred to herein as activation dopants) that, upon exposure to neutrons such as would occur in the fuel salt when a reactor is in operation, undergo a nuclear reaction to, directly or indirectly, form highly active “protecting isotopes” (of the same element as the activation dopant or a different element). A sufficient mass of activation dopants is used so that the Figure of Merit (FOM) of the fuel salt is decreased to below 1.0 within some target number of days of fission. This allows the FOM of the fuel salt to be controlled so that the fuel becomes too dangerous to handle before to the creation of a significant amount of weaponizable isotopes.

This invention discloses a fusion plasma combustion-assisted method for fusion-fission coupling, belonging to the field of nuclear fusion technology. The method includes: evaluating the parameters of ultrafine fission particles to determine the type of fission material, the total injection volume, particle size, and injection velocity; preparing ultrafine fission particles of the appropriate size based on the evaluation results; and injecting the prepared ultrafine fission particles into the fusion plasma at the determined injection velocity, causing the fission material to undergo a fission reaction in the fusion neutron environment, and using the kinetic energy of the resulting fission fragments to heat the fusion plasma. This invention utilizes the energy release at the megaelectron volt level of the fission reaction for heating, which is an improvement over existing kiloelectron volt level technologies, effectively reducing the fusion ignition conditions and accelerating the fusion research process.
