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.

The Frascati Tokamak Upgrade (FTU) neutron activation system has been calibrated using indium foils and a 252Cf spontaneous fission neutron source located at several positions within the tokamak. The same experimental arrangements have been simulated with the MCNP Monte Carlo neutron and photon transport code in order to numerically reproduce the activation response coefficients measured experimentally. The main purpose of the comparison is to assess the accuracy of the numerical simulation and of the modeling of the FTU device. This analysis has a more general relevance in view of the use of the activation system as an independent method for the absolute measurement of the neutron yield in next-step fusion devices. An overall agreement at the 22% level between experiment and calculation has been demonstrated.
