The ninth edition of the annual NEA Thermochemical Database (TDB) Project course on the topic of thermodynamic data collection and assessment will take place in person on the 20 September 2025 at Le Méridien, New Orleans, US, in conjunction with the 19th Conference on the Migration of Actinides and Fission Products in the Geosphere.
The course is designed to familiarise scientists with current NEA TDB activities and standards, provide an overview of data collection and analysis techniques and work through some real system examples to demonstrate the critical evaluation and data assessment process. Retaining high scientific standards for the collection, interpretation, critical review and application of thermodynamic data is a key goal of the NEA TDB, and helps assure that a strong scientific basis for the safety case is maintained to support international nuclear waste management options.
Ideally designed for graduate students, young scientists (typically postdoctoral students) or any scientists who are new to the nuclear chemistry field and its application to nuclear waste management (repository science as well as environmental remediation/containment of near-surface contamination sites). The course also further targets scientists interested in broader environmental applications of the NEA TDB and the collection and application of thermodynamic data.
Tentative Programme:
Topic 1: Backgroud - The TDB Project
Topic 2: Perspective in radioactive waste management and international updates
Topic 3: NEA-TDB Guidelines for ionic strength corrections. Critical review criteria within NEA-TDB
Topic 4: Experimental approaches and design
Topic 5: Thermodynamic databases for radionuclides building on NEA-TDB
Topic 6: Use cases of thermochemical data tables
Topic 7: Use of thermodynamic approaches in nuclear waste disposal Safety Case: insights from the EURAD-2 DITUSC work package
Date and time: 20 September 2025, 09:00-18:00 (Louisiana time)
Location: Le Méridien, New Orleans, USA
Registration deadline: 5 September
Registration fee: EUR 65
