Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

A new three-dimensional code, VENUS+f, for neoclassical transport calculations in nonaxisymmetric toroidal systems is presented. Numerical drift orbits from the original VENUS code and the f method developed for tokamak transport calculations are combined. The first results obtained with VENUS+f are compared with neoclassical theory for different collisional regimes in a JT-60 tokamak test case both for monoenergetic particles and for a Maxwellian distribution; good agreement is found. Successful benchmarking of the bootstrap current in the Wendelstein 7-X configuration with the DKES code for different collisionality regimes as well as further VENUS+f developments are described.
