Abstract. EURAD, the European Joint Programme on Radioactive Waste Management (RWM), is the European Research Programme on RWM, aimed at supporting member states with
the implementation of their national programmes. It brings together over
100 organisations from different backgrounds and countries, which work
together in RD&D projects, Strategic Studies and Knowledge Management
(KM). The importance of KM is recognised by EURAD and reflected in a number of
activities. One essential activity is the capture of the current State-of-Knowledge in the field of RWM and its transfer to the implementation of the
different national programmes. This is done by different types of Knowledge
Documents that are made available through a dedicated IT tool (e.g. a
Wiki). The development of the individual EURAD KM documents is performed by
recognised experts. These experts will share their view on the most relevant
knowledge on a specific topic, highlighting safety functions and operational
aspects. Additionally, signposting to pre-existing documents is performed
(State-of-the-Art Documents, Scientific Papers, etc.). The hierarchy of the
works for the KM documents (Theme Overview, Domain Insight,
State-of-Knowledge, Guidance) is closely linked to the generic EURAD
Roadmap/GBS (Goals Breakdown Structure). It provides a hierarchical structure
that facilitates definition, organisation and communication of topics. All of
this allows knowledge to be captured and presented with the level of detail
that is required by the end-user, from a broad overview down to an increasing
level of detail (pyramid of knowledge). To ensure the quality and consistency
of the documents with the overall EURAD KM approach, quality assurance and
editorial procedures are applied. Collection of end-user feedback will aid the
optimisation and further development of the KM activities. To facilitate the
transfer of knowledge, the EURAD KM programme goes beyond documents and
strives to facilitate exchange between people and signpost to other resources,
such as Training and Mobility activities (also organised by EURAD Work
Package 13 Training & Mobility) or Communities of Practice. All these
activities will contribute to a useful and end-user-friendly EURAD KM
programme that is designed to be operational well beyond the runtime of
EURAD-1. This presentation will provide further insight into the approaches,
status of work and an outlook on future activities that will support member
states with the implementation of their national programmes.
The quantum-mechanical theoretical model for the quantitative description of phase contrast images from non-crystalline objects with arbitrary shapes has been developed. It takes into account multiple scattering effects both in the object (particularly, refraction and phase change) and in the crystals of monochromator and analyzer. Presence of homogeneously and inhomogeneously distributed microdefects and macrodeformations in monochromator-and analyzer-crystals, which influence significantly on the scattering pattern, has been taken into account.
З використанням раніше відкритого авторами явища дисперсійної (фазової) структурної чутливости картини багаторазового розсіяння створено теоретичні й експериментальні основи трикристальної динамічної дифрактометрії багатошарових кристалічних систем з неоднорідно розподіленими мікродефектами та макродеформацією. Враховано динамічний характер когерентного і дифузного розсіяння від дефектів у всіх шарах системи, а також багаторазовість розсіяння між шарами. С использованием ранее открытого авторами явления дисперсионной (фазовой) структурной чувствительности картины многократного рассеяния созданы теоретические и экспериментальные основы трёхкристальной динамической дифрактометрии многослойных кристаллических систем с неоднородно распределёнными микродефектами и макродеформацией. Учтены динамический характер когерентного и диффузного рассеяния от дефектов во всех слоях системы, а также многократность рассеяния между слоями. With using the previously discovered by authors phenomenon of dispersion (phase) structural sensitivity of multiple-scattering patterns, the theoretical and experimental bases of the triple-crystal dynamical diffractometry of multilayer crystalline systems with inhomogeneous strain and randomly distributed defects are created. The dynamical character of both coherent and diffuse scattering from defects in all the layers of the system as well as the multiple scattering between layers are taken into account.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
