Low-temperature distillation is recommended as the method for removing sodium from sodium-bonded, sintered, mixed-carbide fuel pellets. Distillation of the sodium at 5 × 10−6 torr pressure and 485 ± 10°C has no deleterious effect on the microstructure, whereas the porosity may be altered by dissolution techniques.
