To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

A large body of work has been conducted to investigate the embrittlement and degradation
of reactor pressure vessel (RPV) steels. This includes experiments on alloys with different …

The operating environment of nuclear reactors imposes extreme challenges on the materials
from which the structures within and surrounding the reactor are constructed. Understanding …

Cu-rich precipitates formation is associated with the precipitation hardening of Fe-Cu based
steels and the embrittlement of reactor pressure vessel steels under neutron irradiation. The …

Abstract Low enriched uranium (< 20% 235 U)-molybdenum (U-Mo) monolithic fuel is the
primary candidate for high-performance research and test reactors and is in the process of …

Irradiation-induced formation of Cu-rich precipitates embrittles reactor pressure vessel
steels. In the present work, a cluster dynamics model is used to model the precipitation of Cu …

A cluster dynamics (CD) model has been developed to investigate the nucleation and
growth of point defect clusters, ie, interstitial prismatic loops and nanoscale and sub …

In this paper a body-centered cubic (BCC) crystal plasticity model based on microscopic
dislocation mechanism is introduced and numerically implemented. The model is coupled …

Molecular dynamics (MD) simulations are employed to probe the crystallization and
precipitation behaviors in FeCu alloys. The alloys will undergo liquid phase separation at …

High-dispersed nanoscale Cu precipitates often contribute to extremely high strength due to
precipitation hardening, and whereas usually lead to degraded toughness for especially …
