CFS working with NVIDIA, Siemens on SPARC digital twin
Commonwealth Fusion Systems, a fusion firm headquartered in Devens, Mass., is collaborating with California-based computing infrastructure company NVIDIA and Germany-based technology conglomerate Siemens to develop a digital twin of its SPARC fusion machine. The cooperative work among the companies will focus on applying artificial intelligence and data- and project-management tools as the SPARC digital twin is developed.

Experiments of H2-HT isotope separation were carried out with a hot wire column of 3 cm in diameter and 1.5 m in length. Separation factors were measured with cut changed from 0.1 to 0.9, and other operational conditions; pressure, feed rate and temperature difference, fixed. First, the feed rate was altered under the constant pressure, and next, pressure was changed. Experimental results were compared with those from an axisymmetric separative analysis, based on a Newton iterative solution of a convection-diffusion equation. Pressure dependence of separation factors agreeed qualitatively with those from theory. The separative power has a maximum value at 0.12 ∼ 0.16 MPa, when the feed rate was under 100 cm3/m(at 0.1 MPa, 25°C).
