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.

Deep particle fueling into a fusion-relevant plasma can be performed by the injection of cryogenic hydrogen or deuterium pellets. However, the penetration depth and fueling efficiency can be greatly limited when enhanced pellet ablation by fast particles occurs. Only a limited database exists for the penetration depth of ice pellets into stellarators. The penetration depth is measured during pellet injection into purely electron cyclotron resonance heated plasmas on the Wendelstein 7-AS (W7-AS) stellarator. These data are compared with the International Pellet Ablation Database (IPADBASE). Good agreement is found, if the neutral gas shielding model is applied for the scaling law of the penetration depth. The experimental data from W7-AS are used as a basis for planning a new pellet injection system for the Wendelstein 7-X stellarator, which is now under construction.
