METHOD FOR TREATING WASTE MATERIAL
The present invention relates to a method for treating waste material comprising organic components and low and/or medium level radioactive agents. The method comprises encapsulating the waste material into a matrix, gasifying the waste material at a temperature between 600 and 950°C to form a gaseo...

| description | The present invention relates to a method for treating waste material comprising organic components and low and/or medium level radioactive agents. The method comprises encapsulating the waste material into a matrix, gasifying the waste material at a temperature between 600 and 950°C to form a gaseous fraction and a solid fraction comprising low and/or medium level radioactive agents and combustion residues of the organic components and encapsulating the solid fraction by a geopolymer matrix comprising metakaolin.
Esillä oleva keksintö koskee menetelmää jätemateriaalin käsittelemiseksi, joka jätemateriaali käsittää orgaanisia komponentteja ja matalan ja/tai keskitason radioaktiivisia aineita. Menetelmä käsittää jätemateriaalin kapseloinnin matriisiin, jätemateriaalin kaasuttamisen 600-950 °C:n lämpötilassa kaasumaisen osan ja kiinteän osan muodostamiseksi, käsittäen matalan ja/tai keskitason radioaktiivisia aineita ja orgaanisten komponenttien palamisjäännöksiä ja kiinteän osan kapseloinnin metakaoliinia käsittävällä geopolymeerimatriisilla. |
