Patent number: 10902959Abstract: 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.Type: GrantFiled: June 11, 2015Date of Patent: January 26, 2021Assignee: JOINT STOCK COMPANY “AKME-ENGINEERING”Inventors: Petr Nikiforovich Martynov, Konstantin Dmitrievich Ivanov, Radomir Shamillevich Askhadullin, Aleksey Nikolaevich Storozhenko, Andrey Alekseevich Simakov, Aleksandr Urievich Legkih

Patent number: 10424413Abstract: A nuclear reactor plant including a reactor; a coolant in the reactor; a gas system connected to the reactor and adapted to provide a gas supply to and gas removal from a space above the coolant; and a device for injection of gas into the coolant. The device is installed partially in the coolant and partially in the space above the coolant, and is adapted to supply gas from the space above the coolant to the coolant. The gas system and device are configured to carry out steps including: supplying gas to be injected into the coolant from the gas system to the space above the coolant space; injecting gas into the coolant by maintaining the gas pressure higher than coolant pressure in the device; and injecting gas into the gas system from the space above the coolant.Type: GrantFiled: November 6, 2015Date of Patent: September 24, 2019Assignee: JOINT STOCK COMPANY “AKME-ENGINEERING”Inventors: Petr Nikiforovich Martynov, Konstantin Dmitrievich Ivanov, Radomir Shamil'evich Askhadullin, Aleksey Nikolaevich Storozhenko, Alexander Yurievich Legkih, Vladimir Vladimirovich Ul'Yanov, Stepan Artemovich Borovitsky, Alexandr Ivanovich Filin, Sergey Victorovich Bylavkin

Patent number: 10204712Abstract: A method for the inner-contour passivation of steel surfaces of a nuclear reactor consists in filling a first contour of a nuclear reactor with a liquid metal coolant, introducing a reagent into the liquid metal coolant, said reagent interacting with the material of elements of the first contour, forming a protective film, and heating the liquid metal coolant, having the reagent introduced therein, to a temperature allowing for conditions for forming the protective film. The liquid metal coolant having the reagent introduced therein is kept at said temperature until a continuous protective film is formed on the surface of the material of the elements of the first contour. The liquid metal coolant having reagent introduced therein is heated by means of the friction thereof against rotating vanes of a vane pump, which is submerged in the liquid metal coolant.Type: GrantFiled: December 8, 2014Date of Patent: February 12, 2019Assignee: Joint Stock Company “AKME-Engineering”Inventors: Petr Nikiforovich Martynov, Radomir Shamilievich Askhadullin, Aleksey Nikolaevich Storozhenko, Konstantin Dmitrievich Ivanov, Aleksandr Urievich Legkikh, Said Mirfaisovich Sharikpulov, Aleksandr Ivanovich Filin, Sergey Viktorovich Bulavkin

Patent number: 10037822Abstract: The invention relates to the field of nuclear technology, and specifically to a method for the in situ passivation of steel surfaces. The method consists in installing, in a position intended for a regular core, a core simulator in the form of a model of the core, which models the shape thereof, the relative position of the core components, and also the mass characteristics thereof; next, the reactor is filled with a heavy liquid metal heat transfer medium, the heat transfer medium is heated to a temperature which provides for the conditions of passivation, and in situ passivation is carried out in two stages, the first of which includes an isothermal passivation mode in conformity with the conditions determined for this stage, and the second mode includes non-isothermal passivation, which is carried out under different conditions, after which the core simulator is removed and the regular core is installed in the place thereof.Type: GrantFiled: March 19, 2014Date of Patent: July 31, 2018Assignee: Joint Stock Company “AKME-Engineering”Inventors: Petr Nikiforovich Martynov, Radomir Shamilievich Askhadullin, Konstantin Dmitrievich Ivanov, Aleksandr Urievich Legkikh, Aleksey Nikolaevich Storozhenko, Aleksandr Ivanovich Filin, Sergey Viktorovich Bulavkin, Said Mirfaisovich Sharikpulov, Stepan Artemovich Borovitsky
