Patents by Inventor Jacques Figuet

Jacques Figuet has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Secondary heat transfer circuit for a nuclear reactor cooled by a liquid metal such as sodium, as well as a steam generator particularly suitable for such a circuit
    Patent number: 4600554
    Abstract: The invention relates to a secondary heat transfer circuit for a liquid metal-cooled nuclear reactor, as well as to a steam generator which can be used in such a circuit.According to the invention, a downstream buffer tank and an upstream buffer tank are arranged within the steam generator. The upstream buffer tank is annular and surrounds and communicates with an area of the generator by which the liquid metal flows downwards between the exchange zone and the discharge tube. The pressure of the neutral gas pocket in the downstream buffer tank is higher than that of the pocket of the upstream buffer tank.Application to fast neutron nuclear reactors.

  • Secondary heat transfer circuit for a nuclear reactor
    Patent number: 4519978
    Abstract: The invention relates to a secondary heat transfer circuit for a liquid metal nuclear reactor.Each loop of the main circuit has in order a steam generator, a pump, and at least one heat exchanger positioned in the reactor vessel. A downstream buffer tank is located in the pipe connecting the generator to the pump, whilst the upstream buffer tank can be positioned either in the generator, or outside the latter.Application to the generation of electric power by means of a fast neutron reactor.
