AI Fusion Plasma Control

Machine learning for fusion plasma stability and confinement optimization

The Problem

AI Fusion Plasma Control for Stable Confinement and Grid-Aware Power Delivery

Organizations face these key challenges:

1

Plasma dynamics are nonlinear, coupled, and difficult to model accurately in real time

2

Diagnostic streams are high-frequency, heterogeneous, and noisy

3

Rare but costly disruption events create severe class imbalance for model training

4

Control actions must meet strict latency and safety constraints

5

Physics teams, control engineers, and grid operators often use disconnected toolchains

6

Renewable-heavy grids introduce fast voltage fluctuations and congestion uncertainty

7

Operators need explainable recommendations before trusting AI in high-risk environments

8

Historical data may be sparse across new operating regimes and reactor configurations

Impact When Solved

Reduce plasma disruption frequency through earlier instability detection and faster control actionsIncrease confinement quality and pulse performance by optimizing actuator trajectoriesLower experiment downtime caused by failed shots, recovery procedures, and manual retuningImprove grid export value by coordinating plant output with congestion forecasts and voltage constraintsReduce switching wear on stabilizing devices through smoother real-time voltage controlAccelerate controller development using ML surrogates instead of only expensive full-physics simulations

The Shift

Before AI~85% Manual

Human Does

  • Review diagnostic trends after each shot and assess plasma stability risks
  • Tune actuator settings and operating limits between shots based on expert judgment
  • Approve conservative protection thresholds and disruption mitigation actions
  • Decide whether to continue, modify, or terminate high-performance operating scenarios

Automation

  • Provide basic alarms from fixed-threshold diagnostic monitoring
  • Run offline model calculations to support post-shot analysis
  • Generate standard control setpoints from preconfigured physics-based controllers
With AI~75% Automated

Human Does

  • Approve operating envelopes, risk tolerances, and control objectives for each campaign
  • Review AI-recommended control actions during exceptions or unusual plasma regimes
  • Authorize mitigation, derating, or shutdown decisions when disruption risk exceeds policy limits

AI Handles

  • Continuously fuse diagnostic streams into a unified real-time plasma state view
  • Predict instability and disruption risk with actionable warning time
  • Recommend or execute constraint-aware actuator adjustments to sustain stable high-performance operation
  • Adapt control targets in real time as plasma conditions change within approved limits

Operating Intelligence

How AI Fusion Plasma Control runs once it is live

AI runs the operating engine in real time.

Humans govern policy and overrides.
