Abstract
Nuclear microanalysis was used to determine the elemental composition of individual components of the batch for synthesizing surrogates for the lava-like fuel-containing mass and to determine the composition of the surrogates themselves. The elemental composition of the surrogates obtained is compared with that of the real materials. Brown surrogates are found to contain uranium in amounts exceeding 8 mass %. It is found that the elemental composition of the surrogates is nonuniform in different sections of a slab; this could be an indication of incomplete melting of the batch components or the presence a temperature gradient in the heating facility. The decrease of the initial mass of the batch during vacuum melting is due to silicon, calcium, iron, and oxygen losses.
