The process of Thermal Organic Reduction (THOR) to treat Intermediate Level Waste

摘要

THOR~® (Thermal Organic Reduction) is a non-incineration thermal process using pyrolysis and steam reforming to destroy organics and convert the residue into a stable form ready for disposal. The process operates at the relatively low temperature of 850℃ to 950℃, which is below the point that radionuclides such as Cs and Tc volatise. Experience has shown that Cs and almost all other radionuclides are not volatile in the THOR~® process. Thus, the vast majority of the radionuclides are not partitioned to the off-gas, but remain in the primary solid residue.
