Nuclear materials under extreme conditions II

Increasing electricity use for mobility with simultaneous reduced CO2 emissions is only feasible employing nuclear together with renewables. Scientists are searching for new materials and fuels for advanced reactors to ensure both safe operation and efficient energy supply. The symposium will discuss the latest results and planning of next routes.

Scope:

The science and engineering of nuclear materials and fuels, and especially the combined effects of radiation, temperature and chemistry, is an active research field. Many workshops and conference on the subject are therefore application-oriented with a certain lack in addressing basic principles. The scope of our symposium is to highlight basic theoretical and experimental principles, focusing on the fabrication of nuclear materials and fuels to describe key mechanisms responsible for their aging and degradation under the given exposure. The main goal of the symposium is to review the latest progress and chart future advances in experimental and modelling multi scale approaches to describe the synthesize and behavior of these materials under extreme environments like irradiation, mechanical/thermomechanical stress, high temperature and and/or chemically reactive environment.

The symposium will address topics pertaining to nuclear structural materials and fuels, their fabrication and performance under nuclear reactor conditions, especially advanced systems with more demanding parameters in temperature, radiation dose and corrosion. Moreover, the behavior of the waste forms in the repository or alternatively the reprocessing of fuel will be discussed. The addressed theoretical methods span many orders of magnitude from ab-initio up to the mesoscale size. The experimental approaches emphasize the role of advanced techniques, which will allow the understanding of basic processes in synthesis of materials or their degradation mechanisms contributing to the validation of modelling results. As a special form of the connection between experimental and computations methods, machine learning will also be addressed in the symposium, both, for the understanding of the materials, and for the use in advanced manufacturing.
