LPWR deployed concept (deployedLPWR.png)
Clean, safe, affordable nuclear energy — designed for tomorrow's world.
CENERGY is developing the Low-Pressure Water Reactor (LPWR): a 300 MWe Small Modular Reactor that eliminates pumps, high-pressure systems and active safety machinery — replacing them with gravity, density and natural circulation. Meltdown risk removed by design.
Two hard-won grants now protect the LPWR design in Europe and the United States. More milestones are on the way.
We have obtained a US patent grant — issued three weeks ago — securing protection in one of the world's largest nuclear markets. Patent number US-12744130 (US App. No. 18/294,810), issued with a 398-day patent term adjustment under 35 U.S.C. §154(b).

Clean, reliable baseload power is urgent. Yet today's nuclear renaissance is held back by designs that regulators can't easily review and investors can't underwrite.
Molten salt, gas-cooled and fast-neutron technologies push important scientific frontiers and may prove vital in coming decades - but requires new materials databases, novel tech supply chains and regulatory frameworks that don't yet exist — putting utilities and financiers a decade or more from bankable megawatts.
Nuclear authorities worldwide are optimised for water-based systems. Exotic coolants demand entirely new licensing frameworks, competencies and multi-year delays.
High costs, slow development and uncertain approvals have eroded confidence in SMR startups. Capital is waiting for a pragmatic, de-risked platform.
"It must be possible to eliminate the possibility of meltdown by design, using off-the-shelf components." — Emeritus Professor Geoffrey Hewitt (1934–2019)
Density difference between cold water in the outer annulus and steam-filled chimney drives flow, exactly like water rising into a straw with air inside. No coolant pumps. No backflow.
Operating at near-atmospheric pressure (~5 bar) removes high-pressure safety injection systems, redundant active machinery and vulnerable high-pressure welding from the design entirely.
A large borated reactor water storage tank shuts down the reaction and provides cooling for 70 days with no human or computer action required. Gravity inserts shutdown rods.
The analogy of the straw: Heat the bottom of the straw and the mixture inside heats up until it bubbles to steam at some height above the core; it becomes less dense than the water outside, so the surrounding denser, higher-pressure water pushes it up the straw - endlessly. In the LPWR, the reactor core is that heat source at the bottom: the same density difference circulates the whole plant, forever, without a single moving part.
The published design concept. High-density cold water occupies the outer annulus and is pulled down by gravity; the core heats it to near-saturation, flashing to steam in the riser chimney. The saturated steam is dried at ground level and sent straight to low-pressure turbines — one vessel, one loop, no steam generators, no pressuriser.
| Feature | Other SMRs / Gen-IV | CENERGY LPWR |
|---|---|---|
| Coolant system | High-pressure or exotic coolants | Water, near-atmospheric pressure (~5 bar) |
| Core circulation | Forced circulation, pumps | Natural, passive — no pumps |
| Fuel type | Novel or unproven fuels | Standard UO₂, global supply chain |
| Capital cost ($/kW) | $8,000 – $10,000+ (FOAK) | $3,000 – $3,500 target |
| Deployment time | Typically 8–12 years (FOAK-driven) | Faster — modular, repeatable builds with established global supply manufacturers |
| Regulatory alignment | Low — new frameworks required | High — existing light-water precedent |
| Supply chain readiness | Requires new infrastructure | Compatible with existing industry |
Every thermal plant chases efficiency — but efficiency only matters when fuel is expensive. Uranium is abundant, so buying a few extra percentage points of thermal efficiency with resource-intensive high-pressure complexity has rapidly diminishing returns. Dropping from a 50 bar system to a 5 bar costs less than one-third of the thermal efficiency — and the safety and cost gains are enormous.
Low-pressure, density-driven natural circulation removes the systems that dominate conventional reactor cost — and their failure pathways:
Fossil fuels are being retired; renewables are land-intensive and weather-dependent; conventional nuclear is dense and reliable but slow and costly. The unmet need is a safe, fast, scalable way to deliver zero-carbon baseload — without rebuilding the grid.
Facing fossil retirement mandates, they need dispatchable zero-carbon baseload. A fleet of five 300 MW LPWR modules can reach first revenue in ~7 years — versus a single 1,500 MW conventional plant taking far longer.
24/7 uptime demands that wind and solar cannot meet alone. LPWR's modular siting delivers dense, clean power exactly where compute grows fastest.
Clean heat and power for industry, ports and remote regions — built with current industrial supply chains, no exotic materials required.
Same 1,500 MW — but the fleet earns revenue from Year 3.

Beyond the LPWR, CENERGY advises national programmes and companies entering nuclear — from strategy and regulatory readiness to qualifying conventional-industry manpower and suppliers for first nuclear work.
SMR concepts, thermal-hydraulics, safety engineering and licensing strategy — the same depth we apply to the LPWR.
Roadmaps, policy support, feasibility studies, site selection and power-system assessments. Our team contributed technical evaluation and assessment to MyPOWER Corp for Malaysia's potential nuclear power programme.
Commercial structuring, stakeholder engagement and deployment pathways — turning policy intent into programmes that actually reach a concrete pour.
We help companies move people from conventional industries — oil & gas, marine, power generation, heavy manufacturing — into nuclear-qualified roles: welding and NDT qualification (ASME Section IX / ISO 9606; ASNT SNT-TC-1A, PCN and ISO 9712 Level II), AWS certified weld inspection, QA/QC systems training (EN 9100 / NQA-1 principles), and HSE culture for nuclear sites.
Vendor development into nuclear supply chains: material traceability, documentation standards (NCA NQA-1 / 10 CFR 50 Appendix B), ASME Section III fabrication requirements, audit readiness and local-content programmes that keep value in-country.
GDA preparation, safety-case structuring and licensing gap analysis — grounded in firsthand experience of the Hinkley Point C Generic Design Assessment.
Completion of the LPWR demonstration test rig is expected to establish an indicative project value of approximately USD 15 million. Subsequent commercial deployment would generate design licensing revenues of USD 25–40 million per reactor unit, with additional long-term value arising from engineering services, technical support contracts, intellectual property royalties, and other recurring revenue streams.
