The New
Atomic Age for India.

ONIX Nuclear builds factory-made reactors — 1 to 300 MWe — to power data centres, industry, and remote grids beyond the limits of the legacy grid.

SCROLL

Nuclear has always been bespoke.
We're making it a product.

Since its invention, nuclear power has been a one-off, decade-long civil engineering project — a gigawatt plant, poured in place, taking ten years and ten billion dollars to build. To power what India needs next, reactors have to be factory-built, standardized, and shipped on a truck. That's what we're building, beyond the grid.

A New Model

One platform. Two reactor classes.

1–40 MWe
50–300 MWe
050100150200250300 MWe
Proven Technology

Molten salt and TRISO — architectures the world already trusts.

Our reactors use stable molten-salt core architecture as the Phase 1 deployment path, with TRISO-fuelled cores as the Phase 2 upgrade — pairing an unmatched safety profile with a fuel form that is effectively impossible to melt.

Microreactor

ONIX-1

1 – 40 MWe

A sealed-core reactor you can ship. Factory-built, walk-away safe, ten years between refuels — designed for the sites a grid will never reach.

Strategic / Remote Island Grids Industrial Captive Military Bases
Runtime
10 years, no refuel
Footprint
≈ 500–700 m² per unit
Deployment
Factory-built, ~18-month build cycle
Safety
Walk-away passive, natural circulation
Target LCOE
USD 0.08 / kWh
Regulatory
AERB, five-stage consenting track
Small Modular Reactor

ONIX-S

50 – 300 MWe

A modular, multi-unit design that scales in 50 MWe increments — built for grid-scale baseload and the AI data-centre campuses that a single microreactor can't carry alone.

AI Data Centres Utility Baseload Steel / Refining / Aluminium Process Heat / H₂
Configuration
Multi-unit, scalable in 50 MWe steps
Deployment
Modular, factory-assisted (target: 24–36 months)
Positioning
Bridges microreactors and BSMR-class 200 MWe+ designs
Safety
Walk-away passive, inherited core architecture
Regulatory
Same AERB track and SHANTI Act framework
Status
Design target — not yet operationally validated
Built On India's National Reactor Stack

In dialogue with the institutions that built India's nuclear program.

BARC
NPCIL
IGCAR

Early-stage technical dialogue underway, building toward a formal joint R&D collaboration on molten-salt and TRISO-adjacent reactor architecture.

Roadmap

Eighteen months to a validated stack.

Month 06
BARC MoU

AIC-BARC affiliation. Technical liaison appointed.

Month 09
TRISO Sample

Joint fabrication at BARC. FLiNaK loop access.

Month 12
Two LOIs

Data-centre and industrial captive off-take in dialogue.

Month 15
Regulators Open

AERB and NRC pre-application both active.

Month 18
Series A

Validated stack. Open regulatory track. Signed PPAs.

Where we are today — early-stage technical discussions opened with BARC and NPCIL, non-binding LOI conversations underway, core team assembled.

India needs 12× the nuclear capacity it has today. We're building the reactors small enough to get there fast.

This is the atomic decade for India — and it starts with reactors you can ship, not ones you spend a decade pouring in place.
