Investor brief
India's first sovereign private tokamak stack
Executive Summary
Pranos Fusion is the first private tokamak developer in India. The company is vertically integrating HTS magnet manufacturing, advanced plasma control software and the device itself — explicitly targeting a sovereign Indian fusion stack so no single import becomes a bottleneck.
Strategic Thesis
India needs its own end-to-end fusion supply chain; build the magnets, the controls and the machine together so none of them become an import bottleneck.
Technical & Economic Profile
Architecture class
Tokamak & Spherical Tokamak Vanguard
Most mature dataset in fusion. HTS REBCO magnets shrink reactor volume; D-T cycle exploits the highest nuclear cross-section at the lowest temperatures.
Reactor design
Magnetic / Tokamak
Core tech focus
Sovereign domestic HTS manufacturing
Key milestones
Closed seed funding 2024.
How Pranos Fusion sits vs peers
India's vertically integrated sovereign-HTS play. Designed around supply-chain independence rather than a single-shot physics breakthrough.
Class engineering bottlenecks
- 14.1 MeV neutron flux degrades RAFM steel and tungsten armor above ~80 dpa, forcing periodic first-wall replacement.
- Achieving a Tritium Breeding Ratio > 1.0 in compact geometry — especially on space-constrained spherical-tokamak center-posts — is unresolved.
- REBCO tape suffers irreversible critical-current loss above 0.4% tensile strain; > 30 T fields generate GPa-class Lorentz forces requiring MP35N superalloy substrates and carbon-fiber cocoons.
- Sudden plasma disruptions vaporise plasma-facing components — repair downtime is the single dominant LCOE variable per ARPA-E pyFECONs.
LCOE drivers
- Disruption-driven capacity-factor losses (AI digital-twin control projected to cut NOAK LCOE 17–20%).
- ⁶Li enrichment supply chain: ~100 t per plant at $5,000/kg can hit 80% of overnight capital cost.
- Balance-of-plant (steam turbine, heat exchangers, cooling towers) dominates D-T capex.

The Problem
Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.
Low-Aspect-Ratio HTS Tokamak
A compact low-aspect-ratio tokamak combined with domestic HTS magnet manufacturing and an Indian plasma-control software team. The architecture follows the CFS/Energy Singularity high-field compact playbook adapted to the Indian industrial base.
Domestic HTS Manufacturing
Indian REBCO tape and magnet manufacturing capability built in parallel with the device.
Compact High-Field Tokamak
Low-aspect-ratio tokamak geometry to maximise β at small machine scale.
Plasma Control Stack
Indian-developed control software, integrated with the device from day one.
Fuel Strategy
Deuterium-Tritium
Standard D-T fuel cycle.
Product Platform
Pranos Prototype Tokamak
India's first private tokamak under development.
Energy Conversion
Thermal (Rankine/Brayton)
Neutronic (D-T)
33–40% electrical
Deuterium-tritium fusion releases ~80% of its energy as 14.1 MeV neutrons, which deposit their kinetic energy in a surrounding blanket. The heat drives a conventional steam (Rankine) or supercritical-CO₂ (Brayton) turbine.
Conversion chain
- 1D-T plasma
- 214.1 MeV neutrons (80%) + 3.5 MeV alpha (20%)
- 3Neutrons → lithium-bearing blanket (heat + tritium breeding)
- 4Heat → steam/CO₂ turbine → electricity
The most thoroughly understood fusion fuel cycle, highest cross-section at achievable temperatures, and proven back-end engineering (steam turbines are 19th-century technology). Trade-offs: neutron-induced materials damage, tritium handling, ~33–40% Carnot-limited efficiency.
Economic Vision
A vertically integrated Indian fusion stack benefits from a low-cost engineering base and avoids the import-licensing risk that has historically slowed Indian nuclear projects.
Vision
India as a sovereign fusion power producer.
Mission
Build India's first private fusion reactor, end-to-end.
Engineering Bottlenecks
- Domestic REBCO tape supply
- Plasma control talent pipeline
Milestone Timeline
2024
Seed funding round closed
The description above reflects Pranos Fusion's publicly stated technology goals, roadmap and architecture. Many elements — particularly net-energy gain at scale, advanced fuel cycles, and grid-relevant economics — remain ambitious objectives that have not yet been demonstrated commercially anywhere in the fusion industry. Forward-looking statements should be treated as engineering targets, not certainties.
