| titleOfInvention | Treatment method of radioactive solutions containing plutonium and americium |
| abstract | FIELD: power industry. n SUBSTANCE: treatment method of radioactive solutions containing plutonium and americium involves pH correction of base solutions, phase separation by filtration. In order to remove plutonium and americium from medium active waste, two-layer pH correction of the solution is used: the first one to pH=(3.5±0.5) at mixing (25±5) min till primary flocculi are formed; the second one to pH=(8.4±0.2) for deposition of plutonium and americium on deposits of hydroxides; thickened suspension is washed for three times with water at volume ratio of pulp:water of 1:3; decantats (filtrates) and intermediate waters are supply for treatment as per low active waste cleaning procedure; thickened suspension is heat treated at temperature of not more than 850°C so that calcification is obtained, which is supplied either to "temporary" storage for the purpose of removing valuable elements fro it in the future, or to solidification in the form of mineral-shaped matrixes (ferro-silicate, Sinroc-C, etc.), which are suitable for long-term disposal. n EFFECT: invention allows simplifying and cheapening the technological process of medium active waste processing and simplifying the treatment of water-tail solutions. n 1 tbl |
