| 摘要 |
The invention relates to a method and system 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 accompanied by the simultaneous production of environmentally acceptable substances of, for example, borax, calcium-magnesium borates, boron acid and sodium hydroxide solutions. As a result of the radioactive waste treatment method and system according to the invention, the following products are obtained: borax with an environmentally acceptable content of radioactive isotopes that contain only the cesium isotopes with a maximum total concentration of 800 Bq in one kilogram of borax; calcium, magnesium and/or calcium-magnesium borates with an environmentally acceptable content of radioactive isotopes; boron acid solution with an environmentally acceptable content of radioactive isotopes; sodium hydroxide solution containing only the cesium isotopes with a maximum total concentration of 800 Bq in one kilogram of sodium hydroxide; and radioactive waste containing under 5 g/l of boron acid.
