Our Pick Of The Best Australian Nuclear Stocks In September 2026

Oil price volatility is keeping energy security on the agenda for policymakers and investors. Reliable baseload power is back in focus, and Australian nuclear related stocks linked to uranium and reactor supply chains are drawing fresh attention as part of that conversation. This article walks through three nuclear energy stocks from our screener so you can see how different business models offer exposure to this long term power theme.

The three nuclear energy stocks below are just a starting sample. The full screen surfaced 23 more companies with equally compelling narratives that are not covered here. To explore the broader opportunity set, head straight to the Nuclear Energy Stocks screener to identify, filter and analyze potential high conviction ideas.

Worley (ASX:WOR)

Worley is a global engineering and project services company that supports energy, chemicals and resources projects across their full lifecycle, including design, construction, operations, decommissioning and digital solutions. Its nuclear link comes through project delivery and asset management work for nuclear power plants and fuel cycle services, although this sits within a broader portfolio that also spans conventional and low carbon energy. The business generates about A$6.2b of revenue from the Americas, A$4.5b from EMEA and A$1.3b from APAC, and has a market cap of roughly A$4.8b.

Investors looking at nuclear infrastructure may find Worley interesting because it offers a pure service angle on the theme through nuclear project delivery, decommissioning and waste management, rather than exposure to uranium prices. The company has been leaning into energy transition and sustainability work, but recent results showed pressure on margins and a drop in net income, which raises questions about how quickly higher value advisory and digital projects can reshape earnings quality. Funding large, complex nuclear and grid projects with a balance sheet that leans on external borrowings adds another layer of risk. If Worley can translate its nuclear lifecycle role and strong project pipeline into steadier margins and better covered dividends, the story appears more compelling than the headline numbers alone suggest.

Worley’s nuclear project pipeline and global reach could be masking a much sharper margin story than the headline A$6.2b, A$4.5b and A$1.3b revenue split suggests. Get the full picture, including how funding and dividend coverage fit together, in the Worley financial health report

Silex Systems (ASX:SLX)

Silex Systems is a technology commercialization company best known in nuclear circles for its SILEX laser isotope enrichment process, which is being commercialized for uranium enrichment and used to produce fuel for nuclear power reactors through its Silex USA business and licensing. The group reports around A$13.3 million of revenue from its Silex Systems segment and about A$2.1 million from Translucent, with a small inter segment offset, reflecting that nuclear linked enrichment is part of a broader set of projects that also include silicon and medical isotope enrichment. The company has a market cap of about A$1.4b, which prices in meaningful expectations on how far this enrichment technology can scale.

For investors who want direct exposure to the nuclear fuel cycle rather than just uranium mining, Silex Systems offers a rare way to tap into uranium enrichment through its laser based SILEX technology. The company is still loss making and relies on external borrowing, so the risk side of the story is real. The latest full year results in August 2026 showed revenue of A$13.71 million and a loss of A$38.62 million, which underlines how early this commercial rollout still is. A key consideration is whether the enrichment licensing pipeline and long tenured management team can turn that nuclear link into sustainable cash flows that justify the valuation premium.

Silex Systems is already priced for big expectations, yet its laser enrichment story is still early. See how the analyst forecasts for Silex Systems stack up against that A$38.62 million loss and what the market might be missing.

Paladin Energy (ASX:PDN)

Paladin Energy is a uranium focused miner whose Langer Heinrich operation in Namibia supplies uranium used as fuel for nuclear reactors, putting it squarely in the nuclear energy theme. The business currently reports all its US$304 million of revenue from Namibia, with sales flowing mainly to Asia, North America and Europe. The stock has a market cap of about A$5.3b.

Paladin Energy provides direct exposure to producing uranium at a time when nuclear power is back in the energy mix conversation, with Langer Heinrich now at full mining operations and Patterson Lake South in Canada building out a long term growth pipeline. The company has only recently moved into profitability and still carries funding and execution risk as it ramps production and advances PLS, and recent one off losses make the earnings picture harder to read. That combination of growing uranium production, contract backed sales and expectations of premium pricing is a key reason many investors are watching Paladin closely, and why it can be useful to look past the headlines to see what is really driving the story.

Paladin Energy’s uranium story is accelerating, and the real twist sits beneath the surface of those contract backed sales and fresh profitability. Get the full context in the analysis report for Paladin Energy
