In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

A large cylindrical assembly of 6LiD was irradiated by neutrons from a high-intensity deuterium-tritium source. Small samples of 6Li, 7Li, and 6LiH, all encapsulated in lead, were positioned along the assembly axis and served as indicators for 4He and tritium production. The amount of 4He was determined by isotope dilution mass spectrometry while the tritium content of the 6LiH wafers was measured by proportional counting of gas samples. Careful comparison of the results with TART Monte Carlo calculations showed excellent agreement. For 4He generation, the experimental values were 1.01 ± 0.06 times those of the calculations, while for tritium the ratio was 1.055 ± 0.07.
