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.

Understanding of the tritium release process from ceramic breeders is of importance to establish a reliable tritium recovery concept for fusion reactors. Release behavior of tritium produced in the neutron-irradiated Li4SiO4 is investigated by the Thermal Desorption Spectroscopy (TDS). Thermal annealing behavior of the irradiation damages was also studied by Electron Spin Resonance (ESR) method.
These experimental results showed that the annealing process of the damages occurred in the almost same temperature range of tritium released from the neutron-irradiated Li4SiO4. This suggested that the thermal annealing processes of the damages were closely correlated with the tritium release process. It was also found that the thermal annealing consisted of two processes. The activation energies of the two processes were determined to be 0.5 eV and 0.96 eV, respectively.
