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 fusion neutronics benchmark experiment on vanadium-alloy was conducted. Various nuclear quantities related to both neutrons and gamma-rays were measured. It was found through benchmark analyses that all the cross section data of mainly vanadium in recent nuclear data files still involved serious problems. Improvement of these data is strongly required. According to discussion on neutron KERMA factors, the major finding was that neutron KERMA factors based on ENDF/B-VI above 10 MeV were too large due to the larger 51V(n,n'p)50Ti cross section.
