Show HN: SCPN Fusion Core – Tokamak plasma SIM and neuromorphic SNN control
anulum Thursday, February 12, 2026
SCPN Fusion Core is an open-source Python/Rust suite for tokamak plasma simulation with neuro-symbolic compilation to stochastic spiking neural networks for real-time, fault-tolerant control.
Key features: - 26 simulation modes (equilibrium, transport, optimizer, flight simulator, neuro-control, etc.) - Neuro-symbolic compiler: Petri nets → stochastic LIF neurons (sub-ms latency, 40%+ bit-flip resilience) - Validation: SPARC high-field equilibria + ITPA H-mode database (20 entries, 10 machines) + IPB98(y,2) scaling - Multigrid solvers, property-based testing, Rust acceleration, Streamlit dashboard - Install: pip install scpn-fusion

Built to explore neuromorphic approaches to fusion reactor control. Happy to answer questions about the models, compiler, validation, or performance.
