NuScale Power ($SMR) develops a proprietary small pressurised water reactor called the NuScale Power Module, which generates around 77 megawatts of electricity per unit. The design is modular – customers can configure anywhere from one unit up to 12 in parallel, reaching up to 924 megawatts of combined output.

Beyond the reactor hardware itself, $SMR provides services across a plant's full life cycle, from licensing support and testing through to fuel supply and program management. Its customers include domestic and international governments, utilities, state-owned enterprises and technology and industrial companies seeking carbon-free power.

11. Centrus Energy ($LEU)

Centrus Energy (LEU) share price over the last year: started at US$219.10, ended at US$189.19, a change of −13.7%. Range over the period: high US$436.00, low US$146.61. Source: Stake market data. Past performance is not a reliable indicator of future performance.

Price: US$189.19 · Daily: -0.08% · Market cap: US$3.77B · Sector: Energy · Industry: Uranium

Centrus Energy ($LEU) sits in the fuel supply chain rather than the mining or generation side of nuclear power. The company sources and sells low-enriched uranium – the fissile material that goes into the fuel rods utilities load into commercial reactors. Its customers are mainly power plant operators who need a reliable supply of that material to keep their plants running.

The second part of the business is more specialised. Through its Technical Solutions segment, $LEU produces high-assay low-enriched uranium, known as HALEU, which is the fuel type required for many next-generation reactor designs. That work serves both the U.S. government and private customers developing advanced nuclear technologies. With around 300 employees, Centrus is a compact operation, but its role in domestic HALEU production puts it in a part of the supply chain that few other companies currently occupy.

CEO Amir Vexler oversees both the commercial fuel supply business and the government-facing technical work, which gives the company exposure to two distinct customer bases within the same industry.

12. Nano Nuclear ($NNE)

Nano Nuclear (NNE) share price over the last year: started at US$35.13, ended at US$19.38, a change of −44.8%. Range over the period: high US$56.63, low US$14.88. Source: Stake market data. Past performance is not a reliable indicator of future performance.

Price: US$19.38 · Daily: 4.4% · Market cap: US$1.04B · Sector: Utilities · Industry: Electric & IPPs

Nano Nuclear Energy ($NNE) is building out what it describes as a vertically integrated nuclear energy business – covering reactor design, fuel production, fuel transport, and consulting services, all under one roof. Its flagship product is the KRONOS MMR Energy System, a microreactor the company is developing for both small- and large-scale power generation.

The fuel side of the business is equally central. Through subsidiaries HALEU Energy Fuel Inc. and American Uranium Inc., $NNE is working to establish a domestic supply chain for low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) – the fuels that next-generation reactors require. Advanced Fuel Transportation Inc. rounds out that picture by handling the logistics end of moving nuclear fuel.

With just 36 employees under CEO James Walker, $NNE is still firmly in the development phase. Its broad subsidiary structure – including Nano Nuclear Space Inc. and True North Nuclear Ltd. – signals ambitions well beyond a single reactor design, though all of these ventures remain at early stages.

Common questions

How can Australian investors buy nuclear energy stocks?

All 12 stocks in this list trade on U.S. exchanges, so you'd need a share trading platform that provides U.S. market access. Each company is searchable by its ticker. Because these stocks are priced in USD, movements in the AUD/USD exchange rate affect the value of holdings when converted back to Australian dollars.

What are the key risks of nuclear energy stocks?

The risks shift depending on where a company operates. Uranium producers face commodity price swings driven by mine supply, enrichment capacity and government purchasing decisions. Reactor developers carry licensing, construction and commercialisation risk – nuclear regulatory approval processes are lengthy and outcomes are uncertain. Utilities face energy market regulation and the economics of plant licence renewals, and all 12 companies carry AUD/USD exposure given they trade in U.S. dollars.

How do the types of companies in this list differ?

The 12 stocks cover three distinct parts of the nuclear energy landscape. Some are in the fuel supply chain – mining or processing uranium, converting it, or enriching it into reactor-grade fuel. Others are technology and engineering businesses that design reactor systems, manufacture nuclear components or service existing plant. The third group are utilities and power generators that own operating capacity and sell electricity to the grid, treating nuclear as one generation source among several.

What are small modular reactors?

Small modular reactors (SMRs) are nuclear reactor designs built around a smaller, more standardised format than conventional large-scale power plants, with the aim of using factory-manufactured components to reduce construction complexity. NuScale Power ($SMR) has a pressurised water reactor design capable of generating around 77 megawatts per module, scalable up to 924 megawatts across 12 modules. Nano Nuclear Energy ($NNE) is developing microreactor technology through its KRONOS MMR system, alongside a domestic fuel supply chain. Both companies are at early commercial stages, carrying more development and regulatory uncertainty than the established operators and uranium producers in this list.
