OXIDE MATERIAL OF NUCLEAR-REACTOR MOLTEN CORE CATCHER Russian patent published in 2003 - IPC

Abstract RU 2212719 C2

FIELD: nuclear power engineering; sacrifice materials for water-cooled tank reactors. SUBSTANCE: oxide material used for molten core confinement in case of beyond design basis accident includes in its composition Al₂O₃, SiO₂, and also Fe₂O₃ and/or Fe₃O₄. In addition material also includes first additive in the form of Gd₂O₃ or Eu₂O₃, or Sm₂O₃ and second additive of one or more oxides of following group: SrO, CeO₂, BaO, Y₂O₃, La₂O₃. Proportion of ingredients in proposed oxide material is as follows, mass percent: Fe₂O₃ and/or Fe₃O₄, 46-80; Al₂O₃, 16-50; SiO₂, 1-4; first additive, 0.1-4.0; second additive, 3-15. EFFECT: enhanced effectiveness of molten core confinement at beyond design basis accident. 3 cl, 1 dwg, 2 tbl
