The method and system for control of oxygen concentration in the coolant of a reactor plant including a reactor, coolant in the reactor, gas system, mass-exchange apparatus, disperser and an oxygen sensor in the coolant have been disclosed. The method includes the following steps implemented by the system: estimation of the oxygen concentration; comparison of the oxygen concentration with the permissible value; if the oxygen concentration is reduced, comparison of the reduction value and\or rate with the corresponding threshold value; if the reduction value and\or rate of oxygen concentration is below the threshold value, activation of the mass-exchange apparatus; if the reduction value and/or rate of oxygen concentration is above the corresponding threshold value, supply of oxygen-containing gas from the gas system to the near-coolant space and/or activation of the disperser. Technical result: improvement of controllability of oxygen concentration in coolant, enhancement of safety and extension of reactor plant operating life.
A method for control of oxygen concentration in a coolant of a reactor plant including a reactor, the coolant located in the reactor, a gas system with an outlet to a space near the coolant of the reactor, a mass-exchange apparatus installed in the coolant, which contains solid-phase oxides of coolant and is adapted to flowing of the coolant through it, a disperser installed partially in the coolant and partially in the space near the coolant and adapted to supply gas from the space near the coolant to the coolant, and an oxygen sensor in the coolant, the method comprising:
