Fusion System • Frontier Research Reserve
Advanced Fusion Research
Advanced fusion research preserves less mature confinement, geometry, fuel, and conversion ideas without presenting them as near-term power plants. Each concept must be judged by its own measured evidence and its complete facility requirements.

Phase 4 • Concise Comparison
Engineering comparison
Fuel assumptions vary. Advanced or neutron-lean fuel cycles face substantially harder temperature, confinement, reactivity, and materials requirements than deuterium-tritium.
Concept exploration through laboratory research; individual devices and results are not interchangeable.
Plasma-physics discovery, compact-confinement research, neutron-source studies, propulsion research links, and long-horizon energy-system exploration.

System Breakdown
How this branch is organized
Mirrors & Compact Tori
Mirror machines, field-reversed configurations, and spheromaks investigate alternate magnetic geometries and compact plasma states.
Pinches & Electrostatic Systems
Pulsed pinches and electrostatic concepts support valuable experiments but require evidence-specific maturity and application claims.
Advanced Fuels & Conversion
Neutron-lean fuels and direct conversion remain frontier objectives, not established shortcuts around plasma and plant engineering.
Official Public Sources
Reference basis
Public boundary: Concept classification and public research context only. No device parameters, operating sequences, target or fuel preparation, magnet specifications, control logic, materials recipes, calculations, CAD, or build instructions.
10-Phase Reactor Program • Phase 2
Fusion taxonomy specification
Standardized public-safe fields support comparison across every fission and fusion family. Values are intentionally qualitative; licensing data, dimensions, operating windows, calculations, control logic, and build instructions remain offline.
Mirrors, compact toroids, pinches, electrostatic, and other frontier systems
Configuration-specific confinement and credible whole-plant closure
Advanced fuels do not remove activation, maintenance, or waste without demonstrated reactions and materials
Frontier and historical research families
Specification boundary: Family-level technology classification and lifecycle context—not a vendor datasheet, safety analysis, procurement specification, or construction package.
Ten-Phase Reactor Program · Phase 5
Safety and public-trust boundary
Architecture groupings and future concepts do not establish a licensing pathway or safety finding. Apply the exact reactor, material inventory, mission, site, regulator, safeguards, and emergency-planning basis before making deployment claims.
Public claim boundary: No “inherently safe,” “waste-free,” “unregulated,” “no emergency plan,” licensed, commercially ready, or guaranteed-performance claim is authorized.
