【 摘 要 】

Due to the political situation in Germany there will presumably be no final disposal for radioactive waste in the next 30 years. This means, that the operators of nuclear facilities have to ensure a secure long term intermediate storage for radioactive waste products. The Karlsruhe Research Center operated and cooperated with different nuclear research facilities and laboratories with hot cells, which are now dismantled. During operation and decommissioning of the nuclear facilities radioactive waste was produced. The Central Decontamination Department (HDB) of the Research Center Karlsruhe has been conditioning radioactive waste into waste products for final disposal. Until the opening of a final disposal the resulting waste products will have to be stored at the HDB. To ensure secure long term storage, quality preserving measures will have to be taken. For example, the corrosion-preventing coating of the containers has to be kept intact. In case of damage the container has to be repaired or should be replaced. Another long term protection measure is the casting of drums in concrete inside the containers. This provides an additional barrier layer in case of drum corrosion. At HDB 46,500 m(sup 3) of radioactive waste products are in intermediate storage. The main project of the next few years will be the realization of the quality measures. In this paper the different methods are described in detail.
