Zusammenfassung: | FIELD: nuclear power engineering. SUBSTANCE: tank may be used as crucible for melting corium samples and holding melt in the course of experiments simulating severe accidents of various reactors such as pressurized-water ones. Safety coating on inner surface of graphite vessel of tank is proposed to be made of external tungsten layer and internal tantalum layer. External tungsten layer prevents ingress of tank wall material to melt and internal tantalum layer protects external layer against destruction due to reaction between tungsten and carbon of graphite vessel at high operating temperature of reactor wall. EFFECT: improved operating safety of nuclear reactors. 1 dwg, 1 ex |
