Summary:Interaction of lava-like fuel-containing masses of Unit 4 at the Chernobyl NPP with structural concrete in the active phase of the accident of April 26, 1986, was studied. It was found that the fission fragments and the accumulated products contained in spent nuclear fuel penetrated the concrete from lava with different fractionation coefficients K fr . The absolute values of K fr were calculated, and this phenomenon was identified as a factor to be taken into account when estimating the total amount of radioactive waste for the Shelter.
