Pilot tests on radioactive waste disposal in underground facilitiesFunded under: FP2-RADWASTOM 4C
In order to improve the final concept for the safe disposal of high-level radioactive waste (HAW) in salt, thirty highly radioactive canisters containing the radionuclides caesium 137 and strontium 90 in quantities sufficient to cover the bandwidth of heat generation and gamma radiation of genuine HAW will be emplaced in six boreholes located in two test galleries at the 800 m level in the Asse salt mine in the Federal Republic of Germany. For the emplacement of the radioactive canisters into the underground boreholes a complete handling system has been developed and fabricated. A scientific investigation of the interaction of the radioactive canisters and the rock salt was performed in situ as well as in the laboratory. This programme included measurement of thermally and radiolytically induced water and gas release from the rock salt and the radiolytical decomposition of salt minerals. The duration of the emplacement of the radioactive canisters will be approximately five years.
