Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

In this work, the immobilization of simulated radionuclide 90Sr by fly ash-slag-metakaolin–based geopolymer was investigated. It was found that the thermal stability (high-temperature and freeze-thaw resistance) of the geopolymer waste forms were better than that of cement. The geopolymer waste forms can acquire a compressive strength up to 10 MPa after 2 h calcination at 1000°C. Furthermore, the leaching tests revealed that the fly ash-slag-metakaolin–based geopolymer waste forms had lower cumulative fraction leaching rates of 90Sr than that of cement. These results gave encouragement for the idea that the fly ash-slag-metakaolin–based geopolymers could be used as low cost and high efficiency host materials for the immobilization of radioactive wastes.
