Inertia and LLNL accelerate fusion fuel manufacturing

For Inertia, this capsule has a diameter of about 4–5 mm. Formation of a sufficiently smooth D-T ice layer is crucial for ignition. (Image: Inertia)
Inertia Enterprises and Lawrence Livermore National Laboratory have developed a manufacturing process for the thin layer of cryogenically frozen deuterium-tritium (D-T) used in its target design, reducing production time from days to hours, according to the company.
The advance makes target fueling cheaper and reduces the amount of tritium that Inertia would need to hold at a pilot plant, which lowers material handling costs, regulatory burden, and dependence on scarce fuel inventories.
