  • Separation of the mercury isotopes by the indirect photochemical method
    Patent number: 3983019
    Abstract: A method of photochemical separation of the mercury isotopes by the so-called indirect route in which a gas stream of oxygen and butadiene containing a mixture of mercury isotopes is passed through one or a number of vessels placed in series. The gas stream is irradiated by a lamp containing mercury which is depleted in one or a number of the isotopes and said isotopes are recovered in a trap placed downstream of the vessel or vessels.

  • Method for localizing fuel can failures in nuclear reactors
    Patent number: 3957576
    Abstract: Tracer gases are contained in a capsule which is closed-off by a fusible seal and placed within the interior of each fuel-pin can. The capsule is formed of material having a melting point above the operating temperature of the fuel pins within a nuclear reactor. The fusible seal is formed of material having a melting point below said temperature, with the result that the tracer gases are released into the interior of each fuel pin at that temperature.
