摘要： The present invention relates to a method for processing a nuclear fuel comprising a fissile material, SiC and possibly carbon, said method comprising the contacting of said fuel with a chlorine/oxygen mixture at a temperature below 950° C., and more particularly at a temperature between 400 and 900° C., so as to remove the SiC, and the carbon if this is present, from said fuel. The method of the invention makes it possible for example to declad TRISO or BISO nuclear fuel particles, i.e. particles enabling the nuclear fuel to be confined in a sheath or cladding, or to remove an SiC matrix from a fuel having a heterogeneous SiC matrix. The present invention therefore has many applications, especially in the reprocessing of irradiated nuclear fuels.

摘要： An apparatus for forming nano-structures of carbon solids includes a reactor chamber into which extends a plasma torch configured to generate a plasma plume that extends into the interior of the reactor chamber. CO2 from is applied to the plasma plume where the CO2 is dissociated into carbon and oxygen. A plurality of nozzles also extends into the reactor chamber, which sprays liquid water on the plume, cooling at least a portion of the carbon causing it to form solid carbon nano-structures in a mixture of liquid water. The mixture is conveyed to a flocculation tank.

摘要： A novel, compact non-radioactive electron emitter is provided with a cylindrical shape and with an interior space (6), which forms a vacuum chamber. A substrate (7) forms the bottom of the arrangement with a plurality of field emitter tips (5) formed of carbon nanotubes in the interior space (6). The tips are fastened to the substrate. A layer structure forms the cover of the arrangement, having, from the outside towards the interior space (6), an electrode layer (13), which acts as a counterelectrode and is applied to a gas-impermeable and electron-permeable membrane (10). A substrate (11), which is left open in the form of a window (12) in the area above the field emitter tips (6), acts as a carrier substrate for the membrane (10) and the electrode layer (13). A circumferential wall (14) of the arrangement is formed by an electrically insulating material. The field emitter tips (5) and the electrode layer (13) are connected to a d.c. power source, so that the electrons exiting from the field emitter tips (5) are accelerated through the vacuum chamber, window (12) and the membrane (10) towards the electrode layer (13), pass through the electrode layer (13) and enter the ionization area (3) outside the electron emitter (1, 1′).

摘要： The chassis of a spacecraft has one side exposed to ultraviolet photons and another side shielded from the ultraviolet photons. An electrically conductive surface is disposed on the exposed side of the chassis and is electrically isolated from the chassis. A field-emission array device has a gate, an emitter array, a first terminal electrically connected to the gate, and a second terminal electrically connected to the emitter array. The first terminal electrically couples the gate to the electrically conductive surface on the exposed side of the chassis, and the second terminal electrically couples the emitter array to a surface on the shielded side of the chassis. The emitter array discharges electrons from the surface on the shielded side when a voltage difference in excess of a threshold voltage develops between the gate and the emitter array because of differential charging of the exposed and shielded sides of the chassis.

摘要： A SPECT apparatus has a two-dimensional detector that detects radiations from RIs in a patient via a collimator. A correction processing unit corrects plural two-dimensional projection distributions with different projection angles, which are detected by the detector, on a three-dimensional frequency space according to plural correction functions corresponding to plural distances, respectively. Consequently, a fall in spatial resolution having dependency on distances between the respective RIs and the detector is reduced. A reconfiguring unit reconfigures a three-dimensional RI distribution from the plural two-dimensional projection distributions corrected.
