Advanced Energy Structural Materials Research Section

概要

For the safe and efficient operation of advanced
nuclear energy systems, development of robust materials and establishment of reliable system management
methods are essential. This section addresses the mission of establishing the maintenance management
methodology as well as material R & D for advanced
nuclear energy systems such as fusion and fission reactors. Our research interests are as follows:
(1) Theory, modeling, numerical simulation and
data-driven science & technology of irradiated materials
Radiation damage processes in materials during irradiation occur at a wide variety of time and length
scales. To understand this process, so-called multiscale viewpoint and statistical arguments are required. In this section, efforts are made to model material behavior during irradiation complementarily using several computational techniques such as molecular dynamics, ab-initio quantum calculations, kinetic
Monte-Carlo, rate-equation theory analysis, FEM and
CFD. Recently, additional efforts have also been devoted to this research using machine learning, AI (artificial intelligence) and data-driven techniques. ...
