Energy technology firm AMPERA has confirmed that its new modular, supercritical nuclear systems will operate on thorium obtained from Australian suppliers. The raw material will be managed and processed through an internal supply chain established by the business.

“Our strategy is to secure thorium directly at the source and vertically integrate the entire fuel value chain, from mineral supply through advanced fuel production,” said AMPERA Founder and CEO Brian Matthews.

“Thorium offers a compelling combination of abundance, energy potential, economics, and safety, making it an ideal fuel for AMPERA’s advanced microreactors and a promising resource for the broader nuclear industry.”

To manage the import logistics, the business launched an overseas branch named Ampera Australia earlier this year. This expansion builds upon a bilateral critical minerals agreement signed by the United States and Australian governments late last year, which sets guidelines for the extraction and processing of rare-earth elements.

Domestic production strategy

Following the launch of its primary office in Florida this past April, the organization intends to set up a secondary facility within the state dedicated to fuel production.

The manufacturing plant will focus on turning the raw material into tri-structural isotropic (TRISO) fuel kernels. This fabrication process involves proprietary liquid jetting methods and additive manufacturing techniques. The company has filed more than 60 patents and established trade secrets to safeguard these technical designs.

“Thorium is the future for ultra-safe, clean power production,” Matthews added. “By producing TRISO thorium kernels in the United States, we can ensure ample access to the needed fuel supply as we scale up and also minimize price volatility risk.”

Domestic production is intended to shield the company’s manufacturing pipeline from international market shifts. Internalizing the assembly phase ensures that the business maintains a predictable volume of fuel as it expands its hardware assembly lines.

Technical profile of thorium fuel

Using element 90 presents alternative mechanics compared to standard uranium-based nuclear designs. The material is widespread, with crustal reserves measuring approximately three times larger than those of uranium.

When utilized in advanced cycles, it demonstrates a higher fuel utilization rate, which means a larger percentage of the material undergoes fission rather than turning into heavy waste. The material starts out as weakly radioactive and fertile, meaning it must absorb a neutron to become fissile reactor fuel.

Additionally, the chemical byproducts are less suited for weapons production, and the cycle yields a smaller volume of long-lived transuranic elements compared to typical uranium-plutonium processes. 

Documentation from the International Atomic Energy Agency (IAEA) indicates that these fuel cycles could support global electrical infrastructure requirements over a long time horizon.

Generating decades of electricity

The firm’s compact units use a subcritical design that will be permanently enclosed during initial assembly. These modules are intended to generate electricity continuously for three decades without needing a replacement fuel core.

“Through its proprietary TRISO fuel platform, neutron-source technology and advanced additive manufacturing, AMPERA delivers scalable, factory-built, rapidly deployable, emission-free power for data centers, defense, industrial and maritime applications,” concluded the company in a press release.

Thea Energy will develop a virtual model of its planned fusion power plant using software engineering and computation tools. The enterprise aims to replicate its upcoming “Helios” facility as a digital twin, which allows engineers to simulate the plant’s operational variables before construction begins.

To execute this project, the firm is working with technology companies NVIDIA and Synopsys, alongside two federal entities: Argonne National Laboratory and Princeton Plasma Physics Laboratory.

The initiative connects to the US Department of Energy’s Genesis Mission, an agency program that applies data analytics to accelerate projects outlined in the national Fusion Science and Technology Roadmap. 

By simulating physical systems through software, the team expects to lower the capital requirements typically needed for hardware-based exploratory testing. The engineering timeline targets the delivery of grid-ready baseload electricity by 2035.

Distribution of technical responsibilities

The participating organizations provide distinct computational and physical datasets to build the overarching virtual architecture.

NVIDIA provides its Omniverse computing infrastructure to ingest Thea Energy’s baseline code. This framework allows engineers to view three-dimensional operational data and track potential design adjustments simultaneously.

Synopsys is responsible for integrating structural data into a multiphysics software environment. Its primary objective is to analyze the performance of the plant’s breeding blanket, a component that absorbs thermal energy from the fusion core and provides a radiation barrier for the surrounding magnetic systems.

Argonne National Laboratory delivers specialized data on particle interactions and neutronics. By feeding this data into the virtual model, the lab helps train software algorithms to predict how the physical blanket components will handle high-energy particle bombardment.

Princeton Plasma Physics Laboratory supplies numerical codes that map plasma behavior. These calculations provide the digital twin with the rules necessary to model highly turbulent ionized gases under elevated temperature and pressure conditions.

Mechanical design shift

Traditional stellarators require complex, curved three-dimensional magnetic coils to contain plasma. Thea Energy alters this approach by utilizing flat, repeatable planar magnetic coils arranged in a specific geometry. 

Because flat magnets are easier to manufacture, the physical complexity of plasma containment is transferred to computer software.

The control software regulates the magnetic fields dynamically. This configuration permits the system to adjust for physical deformation or material degradation during continuous operations without requiring manual mechanical interventions.

Development sequence

The road map for deployment consists of two primary hardware systems. The initial system, named Eos, serves as a large-scale prototype designed to achieve steady-state fusion and test structural integrity under real operational loads.

Following the validation of the prototype, the company will build the Helios facility, which will operate as a commercial power station in the 2030s. The digital twin framework is designed to function as an active feedback loop between these two systems. 

Engineers will apply data derived from the virtual Helios model to optimize the engineering components of the Eos prototype during its active testing phases.
