Submission + - UK Scientists Achieve First Commercial Tritium Production (interestingengineering.com)
fahrbot-bot writes: Interesting Engineering is reporting that Astral Systems, a UK-based private commercial fusion company, in collaboration with the University of Bristol, has claimed to have become the first firm to successfully breed tritium, a vital fusion fuel, using its own operational fusion reactor.
The milestone came during a 55-hour Deuterium-Deuterium (DD) fusion irradiation campaign conducted in March. Scientists from Astral Systems and the University of Bristol produced and detected tritium in real-time from an experimental lithium breeder blanket within Astral’s multi-state fusion reactors.
“There’s a global race to find new ways to develop more tritium than what exists in today’s world [currently about 20kg] – a huge barrier is bringing fusion energy to reality,” said Talmon Firestone, CEO and co-founder of Astral Systems.
Astral Systems’ approach uses its Multi-State Fusion (MSF) technology. The company states this will commercialize fusion power with better performance, efficiency, and lower costs than traditional reactors.
A core innovation is lattice confinement fusion (LCF), a concept first discovered by NASA in 2020. This allows Astral’s reactor to achieve solid-state fuel densities 400 million times higher than those in plasma.
The company’s reactors are designed to induce two distinct fusion reactions simultaneously from a single power input, with fusion occurring in both plasma and a solid-state lattice.
The reactor core also features an electron-screened environment. This design reduces the energy needed to overcome the Coulomb barrier between particles, which lowers required fusion temperatures by several million degrees and allows for higher performance in a compact size.
