“…For this reason, the focus is on improving the second security barrier. As structural materials for the core of Russian BREST reactors with a lead coolant, it is proposed to use ferrite-martens tic heat-resistant high-alloy steel of the EP823 type, which does not contain nickel [16]. In liquid lead, oxide films are formed on the surface of such steel (from oxygen dissolved in liquid lead).…”

“…Attractive for use are inhibitors that form a special protective film on the metal surface (during the chemical interaction of the inhibitor and corrosion products). The rate of removal of corrosion and erosion products from the core of the BREST-OD-300 reactor is estimated at 39 kg/year [16]. For the BREST-1200 and 2500 reactors, it can be 156 and 325 kg/year, respectively.…”

The main task of the research is to analyze the possibility of using tungsten protective coatings in fast nuclear power reactors cooled by a lead. The author uses computational and optimization research methods. A comprehensive analysis of the properties of tungsten, including the properties of thin tungsten coatings, has been carried out. The results obtained make it possible to consider tungsten coatings of structural materials as multifunctional protective coatings. They perform the functions of protecting against corrosion and erosion of structural materials in liquid lead. They increase the thermal conductivity of fuel claddings and contribute to a decrease in the maximum fuel temperature in the nominal and emergency operating modes of the reactor. The only disadvantage of tungsten when used in nuclear technology is associated with a high neutron absorption cross section. This disadvantage can be an advantage in minimizing the void reactivity effect. The necessary neutron balance is ensured by using a coolant based on lead thorium ores and innovative ceramic fuel with the addition of uranium metal nanopowder. The significance of research is determined by the possibility of the transition of nuclear energy to the status of “green” environmentally acceptable and safe energy in the near future.
