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.

Some properties of the tritide phases formed by the intermetallic compounds Mg2Ni, ZrNi, and LaNi5 have been studied. Whereas ZrNiT3 will retain its stoichiometry indefinitely when sufficient gaseous tritium is available, the stoichiometrics of Mg2NiT4 and LaNi5T6.9 decrease with time. Although all three intermetallic tritides can retain large quantities of the helium-3 tritium decay daughter product in the solid phase, irreversible release of helium begins after several hundred days for ZrNiTx and Mg2NiTx. However, LaNi5Tx retains all of the helium generated in the solid for at least 2400 days. NMR measurements for ZrNiTx and Mg2NiTx imply that helium is retained in microscopic bubbles as previously observed in several binary metal tritides.
