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.

Understanding helium transport and clustering is important for full understanding of fusion material degradation due to neutron irradiation. Molecular dynamics simulations are carried out to study the clustering of He in FeCr alloy. The simulations are performed for He fractions from 0.1 to 0.4 in FeCr alloy at temperatures ranging from 300 to 800 K. It is observed that a minimum of five He atoms is required to form a stable cluster at temperatures in the range 700 to 800 K. An He5-(Fe/Cr)2-V2 complex is found to exist at 300 K. At higher temperatures, the cluster displaces the Fe and Cr atoms from their lattice sites, forming an He5-V complex. The constituent element of the displaced material is then found to migrate inside the system, depending upon the conditions prevailing there.
