Dugis Some new aspects of this complex phenomena were observed and are reported. These non-stoichiometric mixed oxides are a particularly clear example of catalysis by oxygen exchange between the solid and the gas phase. In a nuclear reactor including the bars or plates cooled by a gaseous fluid, burst risks to occur in the sheath assuring the tightness separation between the cooling gas and the fissile materials. Among the various points examined, particular emphasis is given to the devices of original nature such as tubular fuel elements, flattening of the neutron flux by stuffing, behaviour of the reactor tanks and the cooling circuits, the blowers, unloading devices, regulation and functioning of the informations.

Kasida Cookies come in two flavours — persistent and transient. Finally, investigation to date in the CEA on recombination circuits for power reactors is also discussed. The third chapter contains a number of other measurements performed on G1.

The general deuterium conservation equation requires the definition of the quotient of the reactor; the performances of this reactor are characterised by its overall efficiency. The importance is stressed of the security action and regulations which, added to the precautions taken for the construction, ensure the safety of the installations. The analytical method employed is a differential measurement of the thermal conductivity of the gas.

The electrostatic collection and rotating electrode detector is described and its main uses exposed. An important research programme on heavy water reactor physics has been carried out in France for quite a few years.

By this method we have been able to consider the overall fluctuations in a particularly simple form and we have provided a physical significance for certain results obtained more laboriously by other methods. Two further years of operation of the reactor G1 july — july ; Deux nouvelles annees de fonctionnement du reacteur G1. The flux shows a maximum as a function of unsaturation.

Hydrogen alone, hydrogen in the presence of a donor solvent, of additives or, better yet, of catalysts, are the arms at the disposal of all refiners to assert this mastery, to the extent that they do not want to manufacture coke. On trouvera en outre les caracteristiques neutroniques du coeur actif de la pile, une description des principales hachfur et une mention paarallele essais qui ont conduit au fonctionnement normal du reacteur en puissance.

Direct recombination of H, and N, has been brought about under the influence of radiation. These results in a higher mean specific power which is an economic gain and therefore in a smaller doubling time about 10 years. Ce sont les suivantes: STMicroelectronics — Diodes Site: Graded-composition multilayer structures and microstructure are then elaborated by co-sintering.

A survey of the problems arising hacheu irradiating under these various circumstances leads to conclude that it is possible to devise one capsule type suitable to every particular case, and that in a wide temperature range.

This note constitutes the first edition of a Handbook for the calculation of reactor protections. Among other sources of noise, seie analyse hereafter the fluctuations due: In contrast to the classic method of FARKAS we have worked at room temperature the difference of several per cent between the thermal conductivities of ortho and para-hydrogen at this temperature being found sufficiently great and with a continuously recording system.

This allows to define, for each point of the reactor and for detectors detecting neutrons of given velocities, correlation and transfer functions driven by the same white-noise source. The paper describes the basic structural features of the reactor and the results of the experiments for which it has been used.

Spatial flux instabilities, and their control in the graphite gas power reactors; Les instabilites spatiales du flux et leur controle dans les reacteurs de puissance graphite-gaz. Specimen irradiation of fissile or non-fissile materials, carried out under circumstances becoming more and more severe and in reactor of increasing flux bas led to an evolution of irradiation rigs.

This article describes the results of a first series of research on the depollution of exhaust gases from diesel engines by catalytic mufflers. TOP Related Posts.

Magul The string reactor was shown to run isothermal kinetic tests with a paralpele small amount of industrial-sized catalyst particles less than 2 cc and to explore kinetics of fast reaction at high space velocities impossible to achieve in standard fixed bed units with appropriate hydrodynamic conditions. Experience gained in two hacgeur operation of G1; Experience acquise au cours de deux ans de fonctionnement du reacteur G1. The methods proposed have proved practicable as a result of important research parallfle developments on automatic remote control for all the operations which make up the sequences of mounting, demounting and repairing of the construction components. Le refroidissement est assure par du gaz carbonique sous 15 atmospheres. A short study on the technology and the economical advantage of this adjustment is presented. The precision of the measurements is discussed. Seriee of reactivity of reactor G1; Mesures de reactivite sur reacteur G1.
