Abstract The ARC (FN) – FUTURE NOW reactor is a conceptual compact tokamak-based fusion power plant that prioritizes dynamic stability engineering over traditional brute-force magnetic confinement. Drawing on Global Complexity Stability Theory (GCST), the design treats plasma as an accelerating complex system governed by the instability field evolution equation: ∂Ψ/∂t = D ∇² Ψ + C α − γ Ψ The reactor aims to maintain the GCST-Plasma Number Gₚlasma = γ / (α C) ≫ 1 through active, real-time suppression of turbulence and MHD modes, rather than relying solely on high toroidal field strength. Key innovations include the L-Resonator geometry, adaptive magnetic lattice with spectral feedback, resonant zonal-flow excitation, and pulsed parametric heating. The target performance is Qₚlasma > 15, Pfusion ≈ 400–600 MWₜh, and net electric output of 150–250 MWₑ in steady-state operation, with potential transition to aneutronic p-¹¹B fuel cycle.
