  • Method of operating a power generator based on noble metal induced oxidation of a heat transfer surface
    Patent number: 9478319
    Abstract: A method of operating a power generator is provided. The method includes determining an amount of oxides on a heat transfer surface of the power generator as a function of a concentration of a noble metal substance in the oxides; and altering operation of the power generator when the amount of oxides on the heat transfer surface reaches a predetermined value. A method of operating a nuclear reactor is also provided.
    Type: Grant

  • METHOD OF PLATINUM INJECTION INTO A NUCLEAR REACTOR
    Publication number: 20160099084
    Abstract: A method of injecting platinum into a Boiling Water Reactor is provided. The Boiling Water Reactor includes a reactor core including a plurality of fuel rods having a zirconium alloy cladding. The method includes injecting a first platinate compound and a second platinate compound into a nuclear reactor. The first platinate compound is non-alkalizing and the second platinate compound includes an alkalizing element. The first platinate compound and the second platinate compound are injected such that the second platinate compound injected does not exceed a predetermined threshold or such that a value related to an alkalizing element of the second platinate compound does not exceed a predetermined threshold.
