权利人:UNIV NORTHWESTERN
摘要:The invention relates to an improved method for synthesizing uranium hexamethoxide and new mixed methoxy uranium (VI) fluorides from uranium hexafluorides. Irradiation of the products of the invention in the vapor phase, with a pulsed CO 2 gas laser leads to enrichment in the U-235 content of the isotopic mixture containing U-235 and U-238, the degree of enrichment depending upon the laser frequency employed.

权利人:SHOWA DENKO KK; RESONAC CORP
摘要:There is provided an anode for electrolytic synthesis capable of electrolytically synthesizing fluorine gas or a fluorine containing compound by a simple process and at a low cost while suppressing the occurrence of an anode effect. An anode for electrolytic synthesis (3) for electrolytically synthesizing fluorine gas or a fluorine containing compound includes an anode substrate formed of a carbonaceous material and a metal coating film coating the anode substrate. Metal constituting the metal coating film is nickel.

标 题 :Process for the manufacture of a particulate material and particulate material obtained by this process
发明人:SORNAY PHILIPPE; BERTRAND ERIC
权利人:COMMISSARIAT ENERGIE ATOMIQUE
摘要:In one embodiment of the present invention, a process for manufacturing at least one particulate material is disclosed, the process including the following consecutive steps of: a) introducing into a vibrating grinder at least two powders each comprising UO 2 , provided by two different synthesis routes and of close specific surface area; b) shaking the powders into the grinder so as to form a particulate material, the grinding intensity being sufficient to break up the agglomerates and the aggregates in the powders without at the same time breaking up the crystallites in the powders, and the grinding energy being such that all of the agglomerates and aggregates are destroyed. One embodiment of the present invention also concerns a particulate material obtained by this process.

标题 :Process for the manufacture of a dense nuclear fuel material
发明人:SORNAY PHILIPPE; BERTRAND ERIC
权利人:COMMISSARIAT ENERGIE ATOMIQUE
摘要:This invention relates to a process for manufacturing a dense material containing UO 2 , comprising: a) introducing at least two powders each comprising uranium dioxide UO 2 into a vibrating grinder, wherein at least two powders are provided by two different synthesis routes and each powder has a specific surface area close to that of any other uranium-dioxide containing powder introduced into said grinder; b) shaking said powders by means of said vibrating grinder so as to form a particulate material, the grinding intensity being sufficient to break up the agglomerates and the aggregates in the powders without at the same time breaking up the crystallites in the powders, and the grinding energy provided to the powders being such that substantially all of the agglomerates and aggregates are destroyed; c) introducing said particulate material into a mould; d) applying a shaping stress to said particulate material in order to obtain a compacted material; e) carrying out the sintering of said compacted material so as to obtain the dense material.
