Ampera develops a thorium fuel supply chain from an Australian mine to the United States.
**TL;DR**
The Florida-based startup Ampera has set up an Australian subsidiary to secure a supply of thorium for its advanced nuclear fuel program, aiming to vertically integrate its operations from mining to TRISO kernel production, although it currently lacks an operational reactor.
Ampera announced on Monday that it has created Ampera Australia Pty Ltd to procure and import thorium to the United States as part of its advanced reactor program. This subsidiary was established in February 2026 to aid in this endeavor.
As part of its strategy to complete the nuclear fuel value chain, Ampera intends to source raw thorium from Australian deposits, process it, and produce TRISO fuel kernels in Florida, handling all stages internally.
**Why Thorium**
Thorium is found in the Earth's crust three to four times more abundantly than uranium. It generates less long-lived radioactive waste, is difficult to weaponize, and exhibits greater thermal efficiency in specific reactor designs.
However, despite these benefits, thorium has never been used as a large-scale commercial nuclear fuel. The current global nuclear framework is centered around uranium, with no country having established a commercial thorium fuel supply chain. Ampera aims to develop this from the ground up.
**The Reactor**
Ampera describes its system as a factory-built, scalable nuclear energy platform utilizing supercritical technology. The company holds over 60 patents related to nuclear fuel manufacturing, including unique jetting technology for creating TRISO fuel kernels.
TRISO (tri-structural isotropic) particles are small fuel spheres encased in layers of carbon and ceramic, designed to endure extremely high temperatures without melting. This form of fuel is also utilized by X-Energy's Xe-100 reactor, which raised $1 billion through a Nasdaq IPO earlier this year to support AI data centers.
**The Australia Connection**
Australia possesses some of the largest thorium reserves globally, found mainly as a byproduct of rare-earth mineral deposits. In October 2025, the US and Australia unveiled a framework for cooperation in critical mineral supply, focusing on the mining and processing of rare-earth elements.
Ampera's CEO, Brian Matthews, stated that the company's strategy is to “secure thorium directly at the source and vertically integrate the entire fuel value chain, from mineral supply through advanced fuel production.” The Australian subsidiary marks the initial step in this process.
**The Context**
This announcement comes amid rising demand for nuclear energy in the AI sector. Data center operators have entered conditional offtake agreements for about 45 gigawatts of capacity from small modular reactors, nearly doubling the pipeline from a year prior.
Most of this pipeline is centered on uranium-fueled designs, while thorium reactors are still in earlier stages of development. Ampera has not provided a timeline for its first operational unit and is currently in a pre-revenue and pre-reactor phase, with its immediate goal being TRISO kernel production rather than power generation.
Should Ampera achieve commercial-scale production of thorium TRISO fuel, it would provide reactor developers with an alternative to the uranium supply chain largely dominated by Russia, Kazakhstan, and a few Western enrichment facilities. This is significant in a market where energy security and supply chain independence are becoming equally important as cost per megawatt. However, transitioning from 60 patents to a functional fuel supply chain will require years and substantial financial investment, rather than just announcements.
