Our next star is Helical Fusion getting pre-seed investment from Rheos Capital Works, Sony Innovation fund, @plugandplayjp , Biotope and former Microsoft Japan president @J_Miyazawa
Radiative pulsed L-mode operation in ARC-class reactors - fresh one from @CFS_energy and @MIT_Fusion
Enhanced confinement & internal transport barriers create large pressure gradients providing significant bootstrap current fractions. High confinement time allows minimization of plasma current improving stability while also reducing external current drive requirements needed
Recently, high temperature superconductor (HTS) technology has dramatically increased achievable on-axis magnetic field in reactor designs. Since fusion power density scales, this technological advancement provides opportunities to improve self-consistent reactor scenarios
Right now, the tritium used in fusion experiments like @iterorg, and the smaller JET tokamak in the UK, comes from a very specific type of nuclear fission reactor called a heavy-water moderated reactor
Many of these reactors are reaching end of their working life, there are fewer than 30 left in operation worldwide —20 in Canada, 4 in South Korea, and 2 in Romania, each producing about 100 grams of tritium a year. (India has plans to build more, but who knows where it ends
