The ThermAc project aims at extending the chemical understanding and available thermodynamic database for actinides, long-lived fission products and relevant matrix elements in aquatic systems at elevated temperatures. To this end, a systematic use of estimation methods, new experimental investigations and quantum-chemistry-based information is intended. ThermAc is coordinated by KIT-INE and was developed in order to improve the scientific basis for assessing nuclear waste disposal scenarios at elevated temperature conditions.
