Times Cited Count:64 Percentile:90.64(Computer Science, Interdisciplinary Applications)Thermodynamic sorption models (TSMs) can be utilised to provide a scientific basis for Kd setting in the safety case, and for assessing the response of Kd to changes in chemical conditions. The TSM development involves a series of decisions on model features such as surface sites, sorption reactions and electrostatic corrections. There is a lack of consensus on the best ways to develop TSMs, and the NEA has therefore co ordinated an international project to assess the strategies and processes for building a TSM. This paper presents recommendations from the project on a number of aspects of TSM development in the context of radioactive waste disposal. Key recommendations include: definition of modelling objectives, identification of major decision points, a clear decision making rationale with reference to experimental or theoretical evidence, a suitable consultative and iterative model development process, testing to the maximum practicable extent, and documentation of key decisions.

Times Cited Count:1 Percentile:6.7(Physics, Applied)We performed high-resolution scanning tunneling microscopy/spectroscopy on an optimally-doped CaNaCuOCl crystal. The so-called checkerboard local-density-of-state modulation manifests in the spectroscopic map of the optimally-doped sample. In addition, spatially-inhomogeneous energy gap is observed. The gap tends to be buried at elevated temperatures and correlates with the checkerboard modulation. These results suggest that the gap is related to superconductivity which coexists with the checkerboard modulation.
