Thermochemical Database

The TDB project aims to produce a database that: contains data for all the elements of interest in radioactive waste disposal systems; documents why and how the data were selected; gives recommendations based on original experimental data, rather than compilations and estimates; documents the sources of experimental data used; is internally consistent; and treats all solids and aqueous species of the elements of interest for nuclear waste storage performance assessment calculations. The database compiles formation data (Gibbs energies, enthalpies, entropies and heat capacities) for each aqueous species and solid phase of interest, as well as chemical reactions and their corresponding thermodynamic data. Non thermodynamic data (diffusion or kinetics) and sorption data are not considered in the TDB project.

TDB项目旨在构建一个数据库，其中包含放射性废物处置系统中所有感兴趣元素的数据；记录数据选择的原因及方法；基于原始实验数据而非汇编和估算给出建议；记录所使用实验数据的来源；内部保持一致性；并处理所有感兴趣元素在核废料储存性能评估计算中的固态和液态物种。数据库汇集了每个感兴趣液态物种和固态相的形成数据（吉布斯自由能、焓、熵和热容），以及相应的化学反应及其热力学数据。TDB项目不考虑非热力学数据（扩散或动力学）和吸附数据。
