Aquatic Actinide Chemistry and Thermodynamics at Elevated Temperatures (ThermAc)

Repositories for highly active heat producing waste will feature elevated temperatures over a significant period after closure. If early canister failure occurs, radionuclides therefore may contact aquatic systems at higher temperatures. For such conditions, the chemical understanding and available thermodynamic database for actinides, long-lived fission products and relevant matrix elements in aquatic systems has to be improved.

To this end, a systematic use of estimation methods for thermodynamic data and model parameters will be compared to comprehensive experimental results. This allows for the validation of the estimations and quantum-chemistry based information. In addition, fundamental studies for improved process understanding of actinide chemistry at elevated temperatures are performed. Final goal is the assessment of the use of estimation methods to set up a workable thermodynamic database for elevated temperatures with high applicability to topics relevant for nuclear waste disposal. Furthermore, it will be clarified, to which extent systems will remain critical with regard to available thermodynamic data, and which relevant processes at elevated temperatures are still not sufficiently understood.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.

Brackets

You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).

Phrases

Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
