Abstract :
The former process for the cementation of transuranic (TRU) low-level wastes poses several technical problems. Specifically in the US a TRU waste-form has not yet passed the Waste Isolation Pilot Plant prohibition for free liquid. For this reason, treatment of the portland cement based waste-form with supercritical carbon dioxide (SCCO2) is shown to satisfy regulations. The effect of SCCO2 treatment by applying different CO2 pressure and temperature conditions (8.4 MPa
