2001 (English)Patent (Other (popular science, discussion, etc.))
NOVELTY - Oxide material of molten core catcher incorporating Al2O3,SiO2, also contains Fe2O3 and/or Fe3O4, and target dopant of one or more oxides of following group: SrO,CeO2,BaO,Y2O3,La2O3. Proportion of ingredients is, in mass percent: Fe2O3 and/or Fe3O4, 46-80; Al2O3, 16-50; SiO2, 1-4; target dopant, 3-15. The material has content of radioactive strontium and cerium isotopes in gas phase above molten core that is reduced by 2-7 times. USE - For nuclear reactor molten core catcher. ADVANTAGE - Reduced radioactivity of molten core.
