Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Molecular dynamics simulations were conducted using six interatomic potentials for face-centered cubic metals that differed only in the stacking fault energies (SFEs). We investigated the effects of the SFE on interactions between an edge dislocation and a void of 4.0 nm diameter at 13 intersection positions. In the high SFE, most interaction morphologies at the depinning are such that the two partial dislocations reverse into the perfect dislocation locally at the void interface. In contrast, in the low SFE, the partial dislocations are depinned individually from the void with some certain time lag. The critical resolved shear stress (CRSS) is not symmetrical about the center of the void. CRSS is higher when the center of the void is located not on the glide plane, but in the compressive side of the edge dislocation. In some cases for these conditions, climb motion is observed, which further increases CRSS. The probability of climb motion occurrence is higher with higher SFE. In lower SFE, climb motion occurs temporarily, followed by the disappearance of jog by dislocation releasing several vacancies inside of the void. CRSS is higher with higher SFE for all the intersection positions.
