FIELD: power industry.
SUBSTANCE: invention relates to regulation of concentration of oxygen in the heat carrier of the reactor plant (RP). RP comprises the reactor, the heat carrier in the reactor, the gas system, the mass-transfer apparatus, the dispergator and the oxygen concentration sensor for measurement of oxygen concentration in the heat carrier. The method includes the following steps performed by the system: assessment of oxygen concentration; comparing of oxygen concentration with the allowable value; estimation oxygen concentration change; in case the concentration decreases, the value and/or the rate of decrease is compared with the respective threshold value; in case the value and/or rate of decrease of oxygen concentration is less than the threshold value, the mass-transfer apparatus is activated; in case the value and/or the rate of decrease of oxygen concentration is greater than the respective threshold value, the volume near the heat carrier from gas system is supplied by the gas containing oxygen and/or the dispergator is activated.
EFFECT: improvement of controllability of regulation of oxygen concentration in the heat carrier, improvement of safety and increase of service life of the reactor plant.
