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.

The "hydrodynamic source term" has been identified as a possible issue for thick liquid protection schemes in inertial fusion energy reactor cavities. The hydrodynamic source term refers to the ejected droplets due to the primary turbulent breakup of the jets themselves. Droplets are continuously ejected from the surface of the jets and spread about the chamber, possibly interfering with driver propagation and target injection. Published correlations are examined in order to estimate upper limits for the hydrodynamic source term in the case of the robust point design (RPD-2002), an update to the High-Yield Lithium Injection Fusion Energy II (HYLIFE-II) design. Experimental data for vertical turbulent sheets of water issuing into ambient air downward from nozzles of thickness (small dimension) = 1 cm and aspect ratio of 10 are compared with the empirical correlations at near-prototypical Reynolds numbers of 1.3 × 105. A simple mass collection technique was developed to estimate the amount of ejected droplets from the jet surface. Boundary layer cutting is examined as a means of reducing the source term and improving surface smoothness. Alternate flow conditioning schemes are also explored to establish the relative importance of "traditional" flow straightening elements. Planar laser-induced fluorescence was used to visualize the free-surface geometry of the liquid sheet in the near-field region up to 25 downstream of the nozzle exit. These results indicate that boundary layer cutting can suppress the hydrodynamic source term for a well-conditioned jet but is not a substitute for proper flow conditioning.
