  • Method for the heat treatment of material in a reactor having a wall acting as self-crucible
    Patent number: 9181503
    Abstract: A method of thermal treatment of material in a reactor with a high-temperature chamber and with a self-crucible wall, including at least determining liquidus temperature Tliq of ashes derived from the treated material, wherein the operating temperature of the reactor Tfonc in its steady state is then chosen such that Tfonc>Tliq.

  • Nuclear reactor equipped with a core catcher
    Patent number: 5263066
    Abstract: In order to ensure the recovery and confinement of the core of a nuclear reactor, such as a pressurized water reactor, in the case of a serious accident leading to its melting or meltdown, it is proposed that below the reactor vessel (16) be placed a receptacle (20) able to evacuate the water accumulated below the vessel (16) in the initial phase of the accident and then collect the molten core debris. The water automatically flows through overflow and siphon devices (46, 50) into a cooling space (40) located below the receptacle. If the meltdown of the core (18) has been detected, the water contained in tanks (56) flows by gravity into the space (40), so as to entirely immerse the containers (26) placed in said space. The molten core traversing the bottom of the vessel (16) flows into the receptacle (20) and then into containers (26) via meltable plugs (32) and a natural convection flow is established between the tanks (56) and the space (40) in order to ensure cooling.
