  • Publication number: 20240312652
    Abstract: A method treats an internal surface of a metal part made from a nickel-based or cobalt-based alloy of a primary circuit during an operating cycle of a PWR reactor. The method includes estimating a quantity of nickel discharged into the primary circuit by the metal parts of the primary circuit in contact with water of the primary circuit, during an operating cycle of the reactor; calculating a quantity of magnetite necessary for fixing the whole of the quantity of nickel estimated; forming a treated water by dissolving the quantity of magnetite calculated in the water of the primary circuit when the water has a temperature of between 80° C. and 180° C.; and putting this treated water in circulation in the primary circuit so as to form, on the internal surface of at least one metal part, a layer of a protective oxide to fix the quantity of nickel estimated.

  • Patent number: 8603311
    Abstract: The invention relates to a pH measuring device containing a reference cell which includes a tank filled with an electrolyte solution and a platinized platinum reference electrode immersed in the tank. The measuring device also contains a measuring cell. The measuring cell contains a platinized platinum measuring electrode which is immersed in the solution to be measured. The measuring device also contains a temperature regulator to ensure that the temperature is the same in the reference cell as in the measuring cell. The measuring device also contains a particle pressure regulator to ensure that the hydrogen partial pressure is the same in the reference cell as in the measuring cell and a fluid pressure regulator to ensure that the pressure is the same in the reference cell as in the measuring cell.
