Abstract: Results of detailed analysis of material substance of lava-like fuel-containing materials sources (FCM) and clusters with high uranium concentration were presented. Material and energy balance are aggregated in a process model for optimal composition of sacrificial materials and FCM. Quantitative estimate is given for spent nuclear fuelĺ afterheat in a number of other heat energy sources in reactor vault. Conclusion was made that upon condition of 50 % heat loss, remained amount of ôusefulö heat would be sufficient for proceeding of blast furnace version of fuel-containing materials.

Keywords: uranium, fuel-containing materials, sacrificial materials, heat sources, fuel afterheat, material and energy balance.
