Beschreibung
Zusammenfassung:	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
