Interaction of Selected Actinides and Lanthanides with Degradation Products of Organic Low and Intermediate Level Waste

Organic compounds present in LILW in a deep geological disposal are exposed to different conditions affecting their structure and chemical properties. Ionizing radiation, high pH, and microbial activity may lead to the generation of small water soluble organic compounds. These degradation products can probably enhance the mobility of radionuclides due to complex formation. Therefore the interaction of selected degradation products with certain actinides/lanthanides has to be investigated. This is necessary to predict the safety and long term evolution of a nuclear waste repository. This poster presents the objectives of the doctoral thesis and first results.
