A multiscale viewpoint is introduced into the modeling methodology of radiation damage processes in fission and fusion materials, where the p rocesses occur at a wide variety of time and length scales. Attempt is also made to apply this viewpoint to the reactor integrity technology....

Multiscale viewpoint of material's degradation due to irradiation and its possible application to the lifetime assessment of nuclear power plants

Challenging efforts are discussed to establish an advanced methodology for prediction of material's property and performance changes by irradiation, which will be necessary by all means for the advanced reactor maintenance technology in the future. The changes of material's properties and perfor mance caused by irradiation, such as irradiation-induced hardening, ductility loss, and material's degradation leading to reduction in reactor lifetime, are primarily determined by microstructural changes in materi...
