Rolls Royce Holdings And 2 British Nuclear Stocks To Watch

Headline inflation in Australia has returned to 4%, and higher energy costs are part of that story. That keeps the debate around reliable low carbon power firmly on the table for investors. Nuclear energy stocks give you exposure to companies tied to that conversation, from uranium to reactors. This article highlights three nuclear energy stocks from our screener that could help you position your portfolio for this theme.

The three nuclear energy stocks below are just a starting sample, and the full screen surfaced 6 more companies with equally compelling narratives that are not covered here. To size up the full field, identify your preferred angle on the theme and analyze potential high conviction ideas, head straight to the Nuclear Energy Stocks screener.

Rolls-Royce Holdings (LSE:RR.)

Rolls-Royce Holdings builds and services complex power systems across civil aviation, defence and industrial power, with its nuclear link coming from submarine reactors and propulsion in the Defence arm. Civil Aerospace produced about £11.8b in revenue, Defence £5.0b and Power Systems £5.5b, with the group valued at roughly £123b.

For investors tracking nuclear energy as a real-world supply chain rather than a pure uranium story, Rolls-Royce Holdings offers exposure to submarine reactor know-how wrapped inside a much larger aero engine and power systems powerhouse, which is exactly where the next quote picks up the thread.

"A significant portion of current narrative and valuation appears premised on Power Systems segment growth, especially the data center power generation boom, continuing at near-peak rates (20%+ per year) as cloud and AI infrastructure expand."

What really matters now is how one quiet shift in the defence and propulsion mix ultimately feeds through into future margin resilience.

That margin story is only half the picture, and the full narrative for Rolls-Royce Holdings shows how defence nuclear expertise, capital needs and Power Systems momentum could be decoupling beneath the surface.

National Atomic Company Kazatomprom JSC (LSE:KAP)

Kazatomprom is a uranium specialist, with the Uranium division generating about KZT 1,697b of its roughly KZT 1,998b operating revenue, alongside smaller Ulba Metallurgical Plant and other activities. The stock carries a market value near US$17.3b.

Kazatomprom provides direct exposure to nuclear fuel itself, since its main activity is finding, extracting, processing and selling the uranium that keeps reactors running, rather than building power plants or turbines.

"Global structural undersupply of uranium driven by increasing nuclear build-outs, plant lifespan extensions, and a lag in bringing new projects online is supporting a multi-year demand upcycle, positioning Kazatomprom for sustained pricing power and higher sales volumes, which is positive for revenue and margin growth."

The main swing factor is how one rising cost pressure interacts with that tight uranium market to shape future profitability and cash generation.

That cost pressure is only the starting point, and the full narrative for National Atomic Company Kazatomprom JSC shows how uranium pricing, contracts and capital demands could be quietly reshaping Kazatomprom's long term potential.

Centrica (LSE:CNA)

Centrica is a broad-based energy group that supplies gas and electricity, runs services like boiler repair, and generates power, including from UK nuclear assets that tie it into this theme.

Retail activities produced about £16.3b of revenue, with Optimisation adding £6.0b and Infrastructure £1.6b. After inter-segment and contract adjustments, the group carries a market value of roughly £6.6b.

Centrica gives you exposure to nuclear generation inside a much wider energy and services portfolio, where regulated assets and long-term contracts can matter more than daily wholesale price swings.

"Centrica's expanding investment in regulated, low-carbon generation assets (notably the Sizewell C nuclear project), combined with opportunities in potential nuclear life extensions and carbon storage (Morecambe Net Zero), positions the company to capture stable, long-duration, inflation-linked returns amid accelerating decarbonization policies, supporting predictable revenue and enhanced margins over the long term."

What really moves the needle is how one future policy decision shapes the balance between those long-lived projects and the rest of the business.

If that policy call is what really tilts Centrica’s future mix, the full narrative for Centrica shows how regulated nuclear, retail exposure and cash flows could be quietly decoupling.
