This technical report describes the results of the Nuclear Energy Agency's CLAYTRAC project, in which natural tracer data from nine sites was evaluated to assess potential impacts of disposal of radiological waste in geological repositories. It shows scientific information from numerous sites and applies robust analytical methods to improve the understanding of radionuclide migration and evolution of sites for deep geological disposal. These results improve the understanding of sites, and thus the confidence in safety, for geological disposal of radioactive waste.

L'analyse statistique des données spatiales et spatio-temporelles constitue un champ de recherches intense en statistique tant sur le plan théorique que celui des applications. Cet ouvrage fait le point sur les développements les plus récents dans ce domaine. Les domaines d'applications de ces modèles vont de la géostatistique à l'épidémiologie en passant par l'environnement, l'écologie, l'économie...

GEOTRAP is the OECD/NEA Project on Radionuclide Migration in Geologic, Heterogeneous Media carried out in the context of site evaluation and safety assessment of deep repository systems for long-lived radioactive waste. Retention of radionuclides within the geosphere for prolonged periods is an important safety function of deep geologic disposal concepts for radioactive waste. The extent to which retention processes can be relied upon in repository performance assessment depends upon the existence of well-established theoretical bases for the processes. It also depends on support for the operation of specific retention processes, and models for their quantitative evaluation, from a wide range of laboratory and field experiments and observations from nature. The fifth GEOTRAP workshop, "Geological Evidence and Theoretical Bases for Radionuclide-retention Processes in Heterogeneous Media" held in May 2001, looked at radionuclide-retention processes and their consideration and representation in performance assessments. Current approaches to characterising and modelling retention processes, and suggestions for future improvements, were presented and discussed. In addition to the material presented during the workshop, this publication includes a technical synthesis reflecting the discussions that took place as well as the conclusions and recommendations made, notably during the working group sessions.

The first comprehensive book of its kind, this comparison of key features of pension systems of OECD countries provides coverage of retirement ages, benefit accrual rates, ceilings, and indexation. Future pension entitlements are shown for full-career workers at different earnings levels. Indicators measure redistribution in pension systems, the cost of countries' pension promises, and potential resource transfer. Thirty country chapters explain pension systems and replacement rates in detail. Named a ""Notable Government Document"" by the American Library Association. "" Pensions at a Glance
