Residue management

In the course of the residue management, solid and liquid low-radioactive residuals are treated with the objective to decontaminate them to the extent that they can be utilised without incurring damage after corresponding release. If this is impossible, they will be appropriately conditioned for ultimate storage. In the scope of the product control, these casks are subject to measurement with gamma scanner to check compliance with the required limit values. This work is performed in the residue treatment plant (ESR), which was commissioned early in spring of the year 2000.

Radioactive wastewater is collected here and decontaminated by means of a cask and ion exchange system or by precipitation. The resulting sludge and contaminated ion exchanger resins subsequently are filled and dried. Solid radioactive residues and waste can be decomposed, separated, decontaminated and conditioned in the ESR as required. Numerous different tools and equipment is available for this purpose (including, but not limited to plasma cutting machine, separation caissons, ultrasonic bath, in-drum compactor, dry-pressure blasting plant). Furthermore, the residue treatment plant also serves for the conditioning of waste suitable for pouring, which is filled into KONRAD casks according to a plan of procedures released by the Federal Office for Radiation Protection.

Next to a gamma scanner (cask measuring point), two radiochemical laboratories are available for quality assurance and production control.
