Abstract
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 they displaying solid solutions over the full range of relative concentrations. Field emission scanning electron microscopy analysis reveals that the synthesized hydroxyapatite particles were spherical in shape and that their sizes were in the nanometer range. At higher temperature shape is changed due to the sintering process. Nano-emulsion strategy procedure provides a simple pathway for immobilization of Sr isotopes as a single-phase Sr hydroxyapatite at room temperature.
