# The meeting of the Bureau of the Department of Physical and Technical Problems of Power Engineering of the NAS of Ukraine

The meeting of the Bureau of the Department of Physical and Technical Problems of Power Engineering of the NAS of Ukraine was held in National Academy of Sciences of Ukraine on October 8, 2019. Sergii Gabielkov, Doctor of Physical and Mathematical Sciences, Senior Researcher, Head of the Department of Radiation Materials Science and Radiation Instrumentation participated in the meeting. Sergii Gabielkov made a scientific report on the topic “Research of lava-like fuel-containing materials (LFCM) from the complex “New Safe Confinement – Shelter Object”. Using the results of brown ceramics as an example, the main attention was focused on the current state of LFCM. Data on the phase composition, the origin of all detected phases, the crystallization of a glass matrix, the oxidation of uranium oxides in inclusions, and radiation-induced phase formation of uranium silicate weeksite are presented. Specialists of the department take the results into account. It is proposed to complete studies of other types of LFCM ceramics and summarize data for the subsequent development of methodological and technological approaches for creating solid-phase conditioning methods for LFCM to ensure conditions for their long-term storage and/or disposal in the future.
