  • Method For Estimating A Future Value Of The Axial Power Imbalance In A Nuclear Reactor
    Publication number: 20240145106
    Abstract: Method for estimating an axial power imbalance in a nuclear reactor, comprising the following steps: obtaining a reactor power setpoint, for each variable of a plurality of variables of the reactor, determining a sequence of the variable, the sequence representing estimated future variations of the variable, determining a sequence of the axial power imbalance, by taking into account the sequences of the plurality of variables of the reactor, the determination of the sequence of the axial power imbalance using a machine learning module that is trained beforehand on historic reactor data.

  • Refrigeration plant
    Patent number: 11747069
    Abstract: A refrigeration plant including: a first enclosure containing water in the liquid state at a temperature lower than or equal to the temperature of the triple point of water or higher than the temperature of the triple point of water by less than 10° C., and water in the gaseous state at a first pressure equal to the saturated vapor pressure of the water in equilibrium with the pressure of the water in the liquid state; a second enclosure at a second pressure strictly higher than the first pressure by a factor of at least two; a compression device connecting the first enclosure to the second enclosure; a condensing device adapted to condense the water in the gaseous state in the second enclosure into water in the liquid state; and a cold power extraction device for extracting cold power in the first enclosure.

  • Combined installation for the treatment of steel work gases
    Patent number: 6726875
    Abstract: Steel work gases (blast-furnace gases, coke-oven gases, converter gases, etc.) are burnt with an exhaust gas from a gas turbine, optionally with a supply of natural gas and of air, in a combustion section between the outlet of the gas turbine and the inlet of a recovery boiler, the steam from which is utilized especially for producing electrical energy.
