摘要： Apparatus for handling nuclear fuel rods, which include a mixed oxide fuel material, and for constructing fuel assemblies from the fuel rods includes a store (9) constructed from radiation shielding material. The store includes a number of channels (10), each of which is adapted to receive a magazine (2) containing fuel rods. Removal and insertion of magazines from and into the channels is effected by a handling machine (29) which is remotely and automatically operated. Each of the channels is closed by a plug (11) which can be removed and inserted by the handling machine. The handling machine is able to remove a magazine from a selected channel and to deliver the magazine to either of two fuel assembly lines (16, 21). Each assembly line constructs a different type of fuel assembly from that of the other assembly line, and each assembly line is arranged in a separate shielded enclosure (15, 24).

摘要： A neutron monitoring instrument, principally of the survey type, is provided with an inner neutron detector(s) enclosed in a layer of neutron attenuating material and one or more outer neutron detectors provided on the attenuating layer and enclosed in a layer of neutron moderating material. The inner detector(s) monitor neutrons in the 100KeV to 15MeV energy range, with the outer detectors monitoring neutrons in the thermal to 100KeV range. Sensitivity across the spectrum and evenness of response are improved compared with the prior art to give better close equivalence determinations.

摘要： The invention aims to provide coils for inductance applications or magnetic field generation suitable for use in high temperature coils. The invention provides the coil by a non-winding process, in which the conductor path is formed by depositing or removing material served to form a conductor path in its configuration of use relative to other parts of that conductor path. The coil may be formed of one or more elements formed in this way. The conductor paths in individual elements are connected to one another such that the current flows in a consistent sense between layers. A core provided in this way is less susceptible to damage to its insulating or anti-corrosion coatings than a coil produced by coiling a conductor into the coil configuration following insulation and/or anti-corrosion coating. Far higher levels of coil packing are also possible using this construction.

摘要： A method of dissolving in an ionic liquid a metal in an initial oxidation state below its maximum oxidation state, characterised in that the ionic liquid reacts with the metal and oxidises it to a higher oxidation state. The initial metal may be in the form of a compound thereof and may be irradiated nuclear fuel comprising UO2 and/or PuO2 as well as fission products. The ionic liquid typically is nitrate-based, for example a pyridinium or substituted imidazolium nitrate, and contains a Bronstead or Franklin acid to increase the oxidising power of the nitrate. Suitable acids are HNO3, H2SO4 and [NO ]. Imidazolium nitrates and certain pyridinium nitrates form one aspect of the invention.

摘要： A control system for an ac-powered electric motor-generator is arranged to control the voltage applied to stator coils in the motor-generator such that, during a low-speed regime, the power input is controlled by varying the time-averaged voltage applied to the motor within each half electrical cycle, while keeping substantially constant the phase of the applied voltage in relation to the rotational position of the motor-generator. In a high-speed regime, the power input is controlled by varying the phase of the voltage in relation to the rotational position of the motor-generator. In a first embodiment, control is effected, in the high-speed regime, purely by varying the phase of the voltage, and, in a second embodiment, control is effected at high-speed by varying both the phase of the voltage and also the time-averaged voltage applied within each half electrical cycle. In the low-speed regime, power input is controlled using asynchronous pulse width modulation, and, in the high-speed regime, when the time-averaged voltage is varied, control is effected using synchronized pulse width modulation and/or commutation width control.

摘要： The method comprises the steps of directing the beam of a portable laser device (40) onto grout (14) at a power level to cause removal of the grout; causing mutual relative movement between said laser beam and said grout; and, providing removal means (30, 32) for debris resulting from said grout removal. The laser beam (16) is transmitted to the grout (14) via optical fibre. The laser is selected from the group comprising: Nd-YAG laser; semi-conductor laser; and, diode pumped fibre laser, and may also include a low-power visible aiming laser. An area of grout being treated is surrounded by an enclosure (22) to prevent escape of laser light. The enclosure is transparent to optical light and opaque to laser light of the wavelength, e.g. 0.4 to 10.6 mu m, in use. The laser beam spot (18) size being commensurate with the grout width. Debris removal means, possibly assisted with a gas jet (42), comprises suction removal (44) at a position adjacent the grout laser treatment area. The method may include the step of applying additional water to the grout.

摘要： In the reprocessing of irradiated nuclear fuel, fluorination of the fuel is carried out by feeding the fuel to an ionised gas plasma and then contacting the resultant excited species with a fluorinating agent, for example, fluorine, so as to effect fluorination. The ionised gas plasma is an inductively-coupled plasma or a microwave plasma, and the fuel is fed to the plasma in the form of a slurry or a powder fluidised by a gas. Where the slurry is formed from LWR fuel, a variety of volatile and involatile fission product fluorides and actinide fluorides is produced, so enabling the separation of UF6 from the involatile fission product fluorides.
