Energy is
Destiny.

Daratha Atomics is on a mission to build nuclear energy microreactors so nuclear power can be deployed like an aircraft engine, standardized, manufactured, and delivered where demand emerges, from industrial parks to the open ocean.

The Energy Trilemma

Every energy source has tradeoffs. Coal and oil are cheap but dirty. Solar and wind are clean but intermittent. Batteries help, but they don't provide baseload power. Nuclear gets you pretty close to having it all.

RELIABLE GREEN AFFORDABLE Coal Oil Natural Gas Batteries Solar Wind NUCLEAR

Modular nuclear energy is the answer

01

Clean

Low carbon electricity, without the intermittency compromises of renewables.

02

Reliable

24/7 power availability, true baseload, not weather dependent supply.

03

Dense

High energy output from a small physical and land footprint.

04

Scalable

Built for industrial growth, fabs, data centres, and heavy industry.

Why Traditional Nuclear Isn't Enough

Conventional nuclear plants are proven technology built on a model too slow, too capital intensive, and too centralized for the load growth ahead.

Our approach: we want to build reactors like aircraft engines.

One standard design, manufactured at scale in a gigafactory and deployed wherever power is needed, instead of building a massive custom project from scratch every time.

From construction megaproject to factory production line

Standardized // ONE DESIGN

One certified reactor design, deployed infinitely, no bespoke engineering for every site.

Factory Built // NO MEGAPROJECTS

Manufacturing on a production line replaces onsite megaproject construction.

Deployable // WHERE IT'S NEEDED

Power delivered where demand emerges, not only where the grid already reaches.

Why now: Demand, policy, and technology are all coming together at the right time.

JUST ANNOUNCED, AUGUST 26, 2026

IAEA launches ATLAS: a global framework for nuclear power at sea.

The IAEA, alongside 25 member states including India, the US, UK, Japan, and South Korea, launched the Atomic Technologies Licensed for Applications at Sea (ATLAS) initiative in Washington, D.C., a new global framework to enable small modular reactors for civilian ship propulsion and floating nuclear power plants serving offshore and remote coastal communities.

In India's national statement at the launch, the Department of Atomic Energy confirmed that at least five indigenous Bharat Small Modular Reactors (BSMRs) are targeted for deployment by 2033, with smaller capacity units specifically designed as barge mounted floating nuclear power plants. This is the exact reactor class Daratha Atomics is building.

The Daratha edge: our CTO, Rajat Pandey, contributed to India's INS Arihant, a submarine based SMR that has been fielded and operating at sea for years. Very few reactor teams anywhere have hands on experience putting a small reactor inside a marine hull, which is exactly the engineering problem ATLAS is now asking the industry to solve.

Technology

A factory built microreactor platform, ready for this scale of demand.

India's nuclear sector opened to private capital for the first time since independence, and the country's largest industrial groups are already investing.

SHANTI ACT, 2025 Private Participation Enabled Passed by Parliament in December 2025, opening nuclear power generation to private and foreign capital for the first time.
GOVERNMENT COMMITMENT $2.1B Nuclear Mission Fund Allocated to develop indigenous small modular reactors as part of India's Nuclear Energy Mission.
INDUSTRY MOVEMENT India's Largest Groups Investing Tata, Reliance, Adani, and the Aditya Birla Group have all announced or proposed nuclear investment plans.

Our Technology

A proven reactor class, engineered for a footprint that fits almost anywhere power is needed.

Engineering is in active development. These are our current target design parameters, shared at a level appropriate for public discussion.

REACTOR TYPE Pressurized Water Reactor Full tank type design, the same reactor class used in most of the world's operating nuclear power plants.
POWER OUTPUT 10 MWe / 32 MWt Electrical output sized for behind the meter industrial loads, from 32 megawatts of thermal power.
FUEL 3 to 4% Enriched Uranium Standard low enriched fuel, the same enrichment range used in commercial power reactors worldwide.
COOLANT & MODERATOR Light Water The most proven and widely deployed coolant and moderator combination in commercial nuclear power.
CONFIGURATION Two Independent Loops Each loop pairs a canned motor pump with a dedicated steam generator, feeding a common pressurizer for simplicity and redundancy.
FOOTPRINT

The entire reactor building fits inside a fraction of a football field.

FOOTBALL FIELD — 105m × 68m REACTOR BUILDING
20m × 8m × 8m reactor building, generators included
105m × 68m standard football field, for scale
The reactor building occupies roughly 2% of a football field's area, small enough to sit close to the industrial loads it powers.

Business model: One platform serving five types of industrial customers that need large amounts of reliable, always on power, often in places where the grid can't easily provide it.
