All materials arriving at KTE’s disposal facilities are first processed such that non-contaminated components are separated from radioactive waste, leaving behind the smallest possible volume of radioactive waste. The following procedures are applied:
• decontamination, disassembly and compaction of solid non-combustible substances,
• incineration of solid and liquid combustible substances, and
• evaporation and solidification of liquid non-combustible substances.
The radioactive waste is conditioned and packaged ready for storage in a final repository. This must be done in such a way as to meet the storage requirements for the “Schacht Konrad” repository. Until they are transferred to the final repository, the packaged waste remains in purpose-built storage facilities at KTE. The storage capacities are virtually exhausted. They are being expanded because the “Schacht Konrad” final repository is not yet ready for operation but the dismantling projects have to continue.
Substances arriving at KTE for treatment come primarily from the on-site nuclear facilities. Waste from the Baden-Wuerttemberg state collection point, which is likewise treated and stored at this central KTE facility, accounts for only a very small proportion of the total. As far as spare capacities are available, waste treatment services are also offered to external third parties, though the latter are required to take back and store the radioactive waste themselves.
