Carbon sorbents for immobilization of tritium-containing waste oils
Tóm tắt
Emission of tritium from the pump oil-carbon sorbent-cement compositions (where the carbon sorbent is thermally expanded graphite or charcoal fabricated by thermal or radiation evaporation of a cellulose material) was studied. The compositions are characterized by a high hold-up ability with respect to oil components, when the matrix is contacted with water. The apparent diffusion coefficients of tritium are equal to 10−15–10−16 m2 s−1. The compositions are found to be resistant to radiation and can be recommended for solidification of radioactive waste oils.
