Abstrakt: This paper is devoted to the study into the structure of core melts of reactors such as water-moderated water-cooled power reactors. The quenching method is used to experimentally investigate the structure of U-Zr- O melts with an atomic ratio of U/Zr = 1.2–1.6 at a temperature of 2773 K. It is found that, for the most probable compositions of U-Zr-O melts under conditions of heavy accident with the Zr oxidation level above 30%, no separation of the corium melt into immiscible liquids is observed.
