OXIDE MATERIAL OF NUCLEAR-REACTOR MOLTEN CORE CATCHER Russian patent published in 2002 - IPC

Abstract RU 2192053 C1

FIELD: nuclear power engineering. SUBSTANCE: oxide material of molten core catcher incorporating Al₂O₃,SiO₂, in its composition has in addition Fe₂O₃ and/or Fe₃O₄, and target dope of one or more oxides of following group: SrO,CeO₂,BaO,Y₂O₃,La₂O₃. Proportion of ingredients is as follows, mass percent: Fe₂O₃ and/or Fe₃O₄ 46-80; Al₂O₃ - 16-50; SiO₂ - 1-4; target dope 3-15. Proposed material is characterized in that content of radioactive strontium and cerium isotopes in gas phase above molten core is reduced by 2-7 times. EFFECT: reduced radioactivity of molten core. 1 dwg, 2 tbl
