Autonomous, Zero-Carbon Baseload Energy
Rapid on-site installation.
Fully factory-assembled primary systems.
Output: 30 MWt / 10MWe
Global industry and modernized energy grids face an urgent dual challenge: meeting unprecedented baseload power demand while eliminating carbon emissions. Variable renewables alone cannot bridge the gap without expensive backup infrastructure.
The STAR (Safe Tiny Atomic Reactor) nuclear system bridges this divide. Operating on proven Light Water Reactor (LWR) technology, STAR provides 30 MWt of thermal energy and up to 10 MWe of dispatchable electricity. Designed for factory prefabrication, underground deployment, and autonomous operation, STAR offers a bankable, rapidly deployable clean energy asset that functions seamlessly within interconnected grids, local microgrids, or fully isolated power islands.
Proven Physics: The Monoblock Advantage
Eliminating massive pressure vessels in favour of factory-built precision and proven light water physics.
Unlike conventional nuclear reactors and competing Small Modular Reactors (SMRs) that require massive, capital-intensive reactor pressure vessels, STAR utilizes an advanced channel-type core housed within a compact, thin-walled Reactor Monoblock Vessel (RMV).
Field-Tube Channel Core
STAR Pods feature 138 independent pressure channel field tubes, engineered to allow coolant to flow through the fuel assembly, eliminating the need for massive forged pressure vessels.
Proven Light Water Technology
STAR Pods avoid experimental coolants by using well-understood light water as both the coolant and the moderator, alongside standard UO2 fuel and corrosion-resistant E-110 alloy cladding.
Integral Monoblock Housing
The entire primary circuit, including reactor channels and steam generators, is integrated into a single helium-filled steel monoblock vessel for maximum safety.
