Anutara Atomics is building Agaram — a 20 MWe two-fluid, thermal-spectrum thorium molten salt energy system on beryllium-free FLiNaK chemistry. Containerised, dispatchable, inherently walk-away safe, and proliferation-resistant by physics. Designed for AI data centres, heavy industry, and the global supply of life-saving medical isotopes.
India has set a target of 100 GW of advanced power generation by 2047 — and dismantled the state monopoly to get there.
The SHANTI Act of 2025 has opened the sector to private capital, capped operator liability for sub-150 MW systems at a manageable ₹100 crore, and granted statutory independence to the regulator. For the first time, private innovators can build, own, and operate advanced thorium systems on Indian soil.
Beyond the reactor itself, Anutara is committed to advancing the full ecosystem of critical technologies in thorium — supporting development across salt chemistry, materials science, fuel-cycle engineering, isotope extraction, and digital simulation. We see our mission not as building a single product, but as helping mature an entire sovereign capability.
Anutara is positioned as a first mover. Our 20 MWe Agaram concept solves India's energy trilemma — security, affordability, sustainability — using the element we have more of than almost any nation on Earth.
Thorium is mined in Kerala, Tamil Nadu, and Andhra Pradesh. No import dependence. No geopolitical exposure. India's reserves alone can power the country for centuries.
Modular factory build, online refuelling, >95% fuel burn-up, and high-temperature thermal efficiency drive an LCOE that undercuts every alternative dispatchable source.
Carbon-free, dispatchable, 24/7 power. Independent of weather, grid stability, and fossil-fuel price shocks. Aligned to Net Zero — by design, not by storage stack.
Agaram is a two-fluid, thermal-spectrum thorium system. A FLiNaK fuel salt carrying denatured uranium tetrafluoride circulates through a moderated core, hydraulically separated from a thorium-fluoride blanket loop that breeds the next generation of fuel. The fuel is the coolant. There are no fuel rods to melt, no high pressures to contain, and no beryllium in the chemistry. What remains is a problem we have solved by physics, not by paperwork.
A separate thorium-fluoride blanket loop breeds U-233. The bred fissile is denatured with U-238 below weapons-usable enrichment — proliferation resistance built into the fuel chemistry, not bolted on by safeguards.
Lithium-Sodium-Potassium fluoride eutectic. Melts at 454°C. No beryllium toxicity, no Li-7 enrichment burden, no problematic tritium pathway. Characterised by BARC. ~40% cheaper than FLiBe with superior actinide solubility.
A moderated thermal-spectrum core keeps the fissile inventory small. Hydraulic separation of fuel and blanket recovers the neutron economy that single-fluid designs sacrifice when they dilute with U-238.
700°C primary output drives an sCO₂ Brayton cycle through ultra-compact Printed Circuit Heat Exchangers. 45%+ thermal efficiency. Steam Rankine optional.
The most cited molten salt — FLiBe — uses beryllium. Beryllium is acutely toxic, expensive, and generates problematic tritium. We chose FLiNaK because the better engineering and the better economics happen to be the same answer.
Agaram's fuel chemistry is engineered so the fissile stream is non-weaponisable at every point in the cycle. The U-233 we breed is diluted with U-238 below the IAEA's weapons-usable threshold, and is intrinsically hardened by U-232 — a co-produced isotope whose decay chain emits a 2.6 MeV gamma signature that makes covert handling and weapons fabrication both impractical and remotely detectable.
A 20 MWe two-fluid thorium molten salt system on FLiNaK chemistry, engineered to fit inside a standard 40-foot shipping container. Factory-built, road-transportable, pump-free. A reactor you install.
Salt circulates via buoyancy forces alone. No mechanical primary pumps — historically the most catastrophic single point of failure in liquid-cooled systems. We eliminated it.
The entire primary loop is a sealed, replaceable cartridge with a 7–10 year lifespan. Material degradation becomes a factory-controlled recycling process, not a field maintenance crisis.
Manufactured in controlled environments to aerospace tolerances. Transported by road or rail. Installed on site in weeks, not years. ~60% cost reduction vs. traditional builds.
The Agaram is not deployed alone. Each physical unit ships with a continuously running AI digital twin — a high-fidelity virtual replica that simulates the reactor's thermohydraulics, neutronics, and salt chemistry in real time, second by second.
For a liquid-fuel system, this is not a convenience. It is core engineering. The twin lets us observe states that no sensor can directly measure, predict degradation before it happens, and validate every operating decision against physics before it reaches the hardware.
A physics-accurate virtual reactor runs in parallel to every physical unit. Engineers test operating scenarios, fuel-cycle strategies, and fault conditions in the twin first — never on the live system.
Machine-learning models continuously interpret sensor streams from across the salt loops — temperature, flow, redox potential, voltammetry — detecting anomalies and inferring internal states that no probe can measure directly.
The twin forecasts corrosion progression, component fatigue, and cartridge end-of-life — converting maintenance from reactive repair into scheduled, factory-planned replacement well ahead of any failure.
Our twin is not a black box. It is built on validated open-source physics solvers — OpenMC for neutron transport and OpenFOAM for thermohydraulic fluid dynamics. A machine-learning layer accelerates these solvers and continuously re-calibrates them against live plant data, closing the loop between first-principles physics and real-world behaviour. This fusion is itself a critical technology in our roadmap — and one we intend to mature for the wider thorium ecosystem.
We are not competing with the grid. We are competing with diesel gensets, captive thermal plants, and the impossibility of running an AI hyperscaler on intermittent renewables. The Agaram is sized for the customers who cannot wait for transmission.
Hyperscalers need dispatchable, dense, carbon-free power on a 10-year horizon. Renewables plus storage cannot meet the round-the-clock load profile of GPU clusters. The Agaram drops in at the rack-park boundary, 24/7, 99.99% available.
700°C process heat directly substitutes for natural gas and coal in industrial production. Captive deployment at steel mills, cement kilns, and remote defence installations — insulated from grid volatility and import shocks.
The liquid fuel is, by nature, a continuous radiochemical processor. Online milking of Actinium-225 and Molybdenum-99 from the salt — produced as a co-product of power, not as a competing burden.
The same neutron flux that breeds our fuel also seeds a medical-isotope cascade in the blanket. Trace U-232 — an intrinsic by-product of every thorium cycle — decays through Th-228 and Ra-224 to Ac-225, the alpha emitter at the heart of next-generation cancer therapy. We extract it from the salt continuously. Pharmaceutical margins subsidise the cost of electricity. One system. Two revenue streams. Investors get paid before the first kilowatt-hour clears the meter.
A milestone-gated path that retires technology risk before it consumes capital.
