  • Method of maintaining the corrosion resistance of a steel circulation system with a lead-containing coolant
    Patent number: 6019942
    Abstract: The method is to develop an anticorrosive cover out of oxides of structural steel components on a circuit internal surface in which in the course of the circuit operation, the oxygen concentration, which is dissolved in the coolant, is maintained not lower than the value, which has been determined from the expressionIgC=-0.33-2790/T+IgC.sub.S +IgJC.sub.Pb,whereC is the concentration of oxygen, dissolved in the coolant, mass %;T is the coolant maximum temperature in the circuit, .degree. K.;C.sub.S is the saturated concentration of oxygen dissolved in the coolant at the temperature T, mass %;J is the thermodynamic activity coefficient of lead in the coolant, inverse mass %; andC.sub.Pb is the lead concentration in the coolant, mass %.

  • Method of cleaning the inner surface of a steel circulation system using a lead based liquid metal coolant
    Patent number: 5882431
    Abstract: The method is to developed a two-phase flow in the circulation circuit. This method is defined by the fact, that a two-phase flow is developed by means of hydrogen introduction into the coolant. Hydrogen can be introduced in mixture with an inert gas or water steams.
