Good news! Nuclear fusion beats unreliable, intermittent and nature spoiling wind and solar power!
Will ML & AI accelerate the development of nuclear fusion power? You bet! I am also quite sure it will not be "nuclear fusion is decades away from being a viable alternative energy."
"An international collaboration is trying to solve the world’s energy crisis by building a unique kind of fusion reactor.
SMART (SMall Aspect Ratio Tokamak) is a fusion device being put together at the University of Seville in Spain. Over the past month, the team behind its construction has published several papers outlining the fusion technology behind SMART. ...
SMART is unique because it is the only tokamak with negative triangularity. ..."
"... Triangularity refers to the shape of the plasma relative to the tokamak. The cross section of the plasma in a tokamak is typically shaped like the capital letter D. When the straight part of the D faces the center of the tokamak, it is said to have positive triangularity. When the curved part of the plasma faces the center, the plasma has negative triangularity. ...
negative triangularity should offer enhanced performance because it can suppress instabilities that expel particles and energy from the plasma, preventing damage to the tokamak wall. ...
The spherical shape of SMART should make it better at confining the plasma than it would be if it were doughnut shaped. ...
The spherical shape of SMART should make it better at confining the plasma than it would be if it were doughnut shaped. ...
SMART will be the first spherical tokamak to fully explore the potential of a particular plasma shape known as negative triangularity. ..."
From the abstract:
"Linear magnetohydrodynamic (MHD) simulations for the SMall Aspect Ratio Tokamak (SMART) have been carried out for the first time, for both positive (PT) and negative triangularity (NT) shaped plasmas using the MARS-F code. The MHD stability of projected SMART plasmas against internal kinks, infernal modes and edge peeling-ballooning modes have been analyzed for a wide range of realistic equilibria. A stabilization of internal kinks and infernal modes is observed when increasing the safety factor profile and reducing plasma beta. PT shaped plasmas are more stable against both internal kinks and infernal modes than their counterpart NT shaped plasmas. Toroidal flows have little impact on the MHD stability of the internal kinks, but they have a strong stabilizing effect on infernal modes, which can be further mitigated in NT shaped plasmas. The MHD stability of peeling-ballooning modes is reduced in NT shaped plasmas, as observed in conventional tokamaks."
A new and unique fusion reactor comes together with PPPL’s contributions (original news release) "First plasma is coming soon to the University of Seville’s compact spherical tokamak called SMART"
