In this work immobilization of Sr long-lived fission product (LLFP) was evaluated using stable isotope instead of radioactive isotope. Nano-emulsion technique was applied for synthesis calcium - strontium hydroxyapatite as the inert matrix for transmutation of LLFP at room temperature. X-ray powder diffraction analysis accompanied reviled that synthesized powders were single-phase hydroxyapatite and...
CaO-TiO2-SiO2 (sphene) based ceramics has been prepared from a powder mixture (calcite, rutile and amorphous silica) using vibro-milling for homogenization and activation of the precursors. Sphene can be used for nuclear waste disposal. Although many approaches like multi-barrier, glass and ceramic waste forms are available for the nuclear waste disposal, the ceramic waste form is still attractive...
