Notes
  • very interesting, but in purification process of radioactive sea water, is created a new radioactive waste so called - secondary ( for example spent radioactive zeolite)

    I have experimental skills with immobilisation of the radioactive waste via vitrification method and very successfully purification off gas – trapping thermally evaporated Cs137, too. I performed, on the laboratory level, the research immobilisation of Long-lived Intermediate-Level radioactive liquid waste with activity of Cs-137 approximately in the range of 1.1E+9 - 1.E+11 Bq/l so called chrompik (NPP A1 Jaslovské Bohunice - Slovakia).

    I could help with immobilisation - vitrification process because during the last 30 years I have gained the experimental skills in the inorganic chemistry mainly in the area of silicate chemistry, especially in the glass chemistry.
