Price: US$8.02 · Daily: 4.4% · Market cap: US$3.30B · Sector: Utilities · Industry: Electric & IPPs

NuScale Power ($SMR) designs and licenses a proprietary small modular reactor – a pressurised water reactor that produces around 77 megawatts of electricity per unit. The design is built to scale: customers can configure up to 12 modules in a single array, reaching a combined output of 924 megawatts.

With 428 employees, $SMR operates as a technology and licensing business rather than a plant operator. It aims to support customers across the full project lifecycle, from licensing and training through to fuel supply and program management, serving 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$356.28, ended at US$153.88, a change of −56.8%. Range over the period: high US$436.00, low US$138.18. Source: Stake market data. Past performance is not a reliable indicator of future performance.

Price: US$153.88 · Daily: 8.8% · Market cap: US$2.89B · Sector: Energy · Industry: Uranium

Centrus Energy Corp. ($LEU) sits at a specific point in the nuclear supply chain: it supplies the fuel that goes into reactors, rather than building or operating them. Its core business is low-enriched uranium (LEU), the fissile material that commercial utilities need to keep nuclear power plants running. $LEU sources LEU through a network of suppliers and sells it primarily to those utility customers.

The second part of the business, its Technical Solutions segment, goes a step further. It produces high assay low-enriched uranium – known as HALEU – which is the fuel type required by many next-generation and advanced reactor designs. That work serves both the U.S. government and private sector customers, and sits alongside other advanced manufacturing and technical services. With around 300 employees, led by CEO Amir Vexler, $LEU is a relatively compact operation for the role it plays in the nuclear fuel cycle.

12. Nano Nuclear ($NNE)

Nano Nuclear (NNE) share price over the last year: started at US$53.63, ended at US$16.49, a change of −69.3%. 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$16.49 · Daily: 6.3% · Market cap: US$832.9M · Sector: Utilities · Industry: Electric & IPPs

Nano Nuclear Energy ($NNE) is working on multiple parts of the nuclear supply chain at once. Its reactor arm is developing the KRONOS MMR Energy System, a microreactor the company says is designed to serve both small- and large-scale power needs. With just 36 employees under chief executive James Walker, $NNE is firmly at the development stage rather than the operational one.

Beyond the reactor itself, $NNE runs a fuel processing business aimed at building a domestic supply chain for low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) – the fuel grades that advanced reactors require. A separate transportation arm and a nuclear consultation services unit round out the portfolio. The subsidiary structure, which includes entities like HALEU Energy Fuel Inc. and Advanced Fuel Transportation Inc., reflects the company's ambition to control multiple steps of the nuclear fuel cycle rather than focus on any single piece.

Common questions

How do I invest in nuclear energy stocks in New Zealand?

All 12 stocks in this list trade on U.S. exchanges, so you'd buy them through a share trading platform with access to U.S. markets. You search by ticker or company name, place an order in USD, and shares settle in your account like any other U.S. stock. Some platforms also support fractional shares, which lets you access higher-priced names without buying a whole share.

What are the key risks of nuclear energy stocks?

Some of the key risks include regulatory hurdles, uranium price volatility, technology execution risk and currency exposure. Nuclear is among the most heavily regulated industries anywhere – new reactor designs, mining projects and fuel facilities need regulatory sign-off before they can operate, and that process can be slow or fail. Companies at an early development stage may generate little or no revenue while working toward commercialisation, making their prospects sensitive to funding availability and timeline delays. Movements between the NZD and USD affect what any purchase costs and what sale proceeds are worth in New Zealand dollars.

What are the different types of companies in this list?

The 12 names here cover at least three distinct business models. Some mine and process uranium – the fuel itself – and sell it to power generators. Others are utilities or power producers that operate nuclear generation assets, often alongside wind, solar or gas. A third group develops nuclear technology: reactor components, advanced fuel systems, or next-generation reactor designs. Revenue drivers and risk profiles differ considerably across these groups, even though they all connect to the nuclear energy theme.

What are small modular reactors?

A small modular reactor (SMR) is a nuclear reactor designed to generate electricity at a fraction of the output of a conventional plant, with a smaller footprint intended to reduce construction complexity and cost. Two companies in this list – NuScale Power and Nano Nuclear – focus specifically on SMR and microreactor technology, rather than operating existing conventional reactors. Neither has reached commercial-scale operation, so they carry meaningful technology, regulatory and funding risk at this stage of development.
