METHOD AND SYSTEM FOR REGULATING THE CONCENTRATION OF OXYGEN AND HYDROGEN IN A REACTOR FACILITY, AND NUCLEAR REACTOR FACILITY

摘要

Disclosed are a method and a system for regulating the concentration of oxygen and hydrogen in a coolant of a reactor facility comprising a reactor, a coolant located in said reactor, a gas system, a mass transfer apparatus, a disperser and a sensor for sensing the oxygen concentration in the coolant. The method includes the following steps, carried out by the system: evaluating the oxygen concentration; comparing the oxygen concentration with upper and lower permissible values; in the event that the oxygen concentration is greater than the upper permissible value, checking whether the mass transfer apparatus is active and/or deactivating same and/or transmitting a signal about the need to deactivate same, and supplying a hydrogen-containing gas from the gas system to the reactor and/or activating the disperser; in the event that the oxygen concentration is less than the lower permissible value, checking whether the disperser is deactivated and/or the supply of a hydrogen-containing gas to the reactor has ceased, and/or deactivating the disperser and/or ceasing the supply of hydrogen-containing gas, and/or transmitting a signal about the need to deactivate the disperser and/or cease the supply of hydrogen-containing gas, and/or supplying a gas which does not contain hydrogen, and activating the mass transfer apparatus. Technical result: preventing the simultaneous supply of hydrogen and oxygen to a coolant, and increasing the safety and service life of a reactor facility.
