METOD AND INSTALLATION FOR THE TREATMENT OF A RADIOACTIVE WASTES

摘要

This invention concerns a method and an installation for the treatment of radioactive wastes produced as a consequence of the operation of nuclear power plants with pressurized water reactors and boron reactivity regulation and will take place for the production of substances like borax with environmentally allowed content of radioactive isotopes that contains only the cesium isotopes with maximum total concentration of 800 Bq in one kilogram of borax; calcium, magnesium or calcium-magnesium borates with environmentally allowed content of radioactive isotopes; boron acid solution with environmentally allowed content of radioactive isotopes; sodium hydroxide solution containing only the cesium isotopes with maximum total concentration of 800 Bq in one kilogram sodium hydroxide; radioactive waste containing under 5 g/l of boron acid.
