  • Publication number: 20140171724
    Abstract: A process for chemical stabilization of a uranium carbide compound having formula: UCx+yC with x?1 or 2 and y>0, x and y being true numbers, placed in a stabilization chamber, comprises: a rise in chamber internal temperature for “oxidation” of the compound based on uranium carbide between approximately 380° C. and 550° C., the chamber being fed with a neutral gas; isothermal oxidative treatment at the oxidation temperature, the chamber being placed under O2 partial pressure; controlling completion of stabilization of the compound, comprising monitoring the amount of molecular oxygen consumed and/or carbon dioxide or carbon dioxide and carbon monoxide given off, until achievement of an input set-point value for the amount of molecular oxygen, of a minimum threshold value for the amount of carbon dioxide or minimum threshold values for the carbon dioxide and carbon monoxide. A device implements the process.

  • Publication number: 20130336833
    Abstract: The invention relates to a powder of an alloy based on uranium and molybdenum in a metastable ? phase, which is formed of particles which have an elongation index at least equal to 1.1, a non-zero closed porosity value and which are composed of grains having a molybdenum content, for which the variations within the same grain are of at most 1% by mass. It also relates to a method allowing preparation of this alloy powder as well as to the use of said powder for manufacturing nuclear fuels and targets for producing radioisotopes. Applications: Manufacturing of nuclear fuels, notably for experimental nuclear reactors; manufacturing of targets for producing radioisotopes, notably for the medical industry.

  • Publication number: 20130333519
    Abstract: The invention relates to a method for preparing a powder of an alloy based on uranium and molybdenum in a metastable ? phase, which comprises: a) putting at least one first reagent selected from uranium oxides and mixtures thereof, uranium fluorides and mixtures thereof, into contact with a second reagent consisting in molybdenum and a third reagent consisting in a reducing metal, the first, second and third reagents being in a divided form; b) reacting the reagents at a temperature?the melting temperature of the third reagent and under an inert atmosphere, whereby this reaction leads to the formation of the alloy comprising uranium and molybdenum in the form of a powder, for which the particles are covered with a reducing metal oxide or fluoride layer; c) cooling the so formed powder at a rate at least equal to 450° C./hour; and d) removing the reducing metal oxide or fluoride layer which covers the particles of the powder of the alloy comprising uranium and molybdenum.

  • Patent number: 8054082
    Abstract: The measurement is carried out by a device of two non- dissociable measurement chains resulting in a continuous measurement which is representative of the total concentration of tars (even as traces) of a hot gas. It involves coupling of methods including one, SPME/GC/MS/PID, which is discontinuous and a priori partial, the other, PID, which is continuous but difficult to interpret alone. It is based on on-line processing of the elements transmitted by each of the measurement methods used. A tar generator (28) allows calibration of the apparatuses and calculation of the different coefficients required.

  • Patent number: 7968055
    Abstract: The measurement is conducted by means of thermogravimetric scales (10) bearing at one end of the beam (20) a catalyst body (30) for catalysing a coking reaction of the tars present in the gas state. Precautions are taken in order to ensure homogeneity and regularity of the sampled gas flow and to guarantee predominant catalysis on the catalytic body (30), the weight increase of which gives the weight of the deposited coke and indirectly the content of tars present in the gas state in the gas to be measured. A calorimetric device (34) for analyzing gases from the coking of the tars provides a complementary and/or additional measurement. The solid tars are filtered beforehand, but their content may be measured by an auxiliary device. Possible application to analyzing gases from biomass.
