AtkinsRéalis Group And 2 More Nuclear Power Stocks To Watch

China’s latest producer price jump, partly linked to higher energy costs, shows how power hungry the global economy has become as AI and heavy industry demand more electricity around the clock. Investors now face a simple question: Who owns the assets that can supply reliable, carbon free power at that scale? This article walks through three stocks from our nuclear power shortlist that directly plug into that long term theme.

The three stocks that follow are just a small sample from this theme, and the full screen surfaced 14 more nuclear players with equally compelling long term stories that are not covered below. To see the wider field and focus on your own highest conviction ideas, head straight into the Nuclear Renaissance screener to identify, compare, and analyze the most interesting opportunities in one place.

AtkinsRéalis Group (TSX:ATRL)

Overview: AtkinsRéalis Group is a global engineering and project delivery firm, with a dedicated Nuclear segment supporting reactor projects and long term plant operations.

Market Cap: CA$13.9b

AtkinsRéalis Group matters for the Nuclear Renaissance theme because its nuclear engineers and project teams are directly involved in designing, building and extending the life of reactors that can keep AI data centers and grids supplied with round the clock carbon free power.

"Record nuclear revenue growth in early 2026 and an increased full year nuclear revenue outlook to about $2.7b indicate that AtkinsRéalis Group is monetizing its nuclear backlog and recent contract wins, which directly supports higher future revenue and earnings quality."

What happens to margins and cash generation if a single assumption about how efficiently that contracted work converts into profits breaks?

If that question is on your mind, go straight to the full narrative for AtkinsRéalis Group to learn how AtkinsRéalis Group’s nuclear work could decouple backlog, earnings quality and risk.

Cameco (TSX:CCO)

Overview: Cameco is a Saskatoon based uranium and nuclear fuel supplier. Its mining, fuel services and Westinghouse operations power 24/7 carbon free electricity.

Operations: Cameco generates about CA$2.9b from Uranium, CA$555 million from Fuel Services and CA$3.6b from Westinghouse, plus minor Other revenue.

Market Cap: CA$43.8b

Cameco matters for the Nuclear Renaissance theme because without a secure flow of uranium and fuel services, new and existing reactors cannot keep AI data centers supplied with constant low carbon power.

"Cameco continues to be tied to a global wave of new nuclear construction, with government-backed programs in countries such as Canada, the U.S. and those pledging to expand nuclear capacity expected to support uranium and fuel demand over many years, which can feed into higher long-term revenues."

The real test for Cameco’s Nuclear Renaissance role lies in how one pressure on its uranium economics ultimately shapes long term margin potential.

That margin pressure is exactly where the story gets interesting. Read the full narrative for Cameco to see how Cameco’s fuel mix could reshape long run earnings power.

TKMS & Co KGaA (XTRA:TKMS)

Overview: TKMS AG & Co KGaA designs and builds submarines, surface warships and integrated naval electronics that support nuclear-capable fleets.

Operations: TKMS generates about €1.3b from Submarines, €543 million from Surface Vessels and €833 million from Atlas Electronics each year.

Market Cap: €5.0b

TKMS & Co KGaA ties into the Nuclear Renaissance theme through its submarines, support ships and sonar systems that sit beside nuclear-powered fleets underpinning 24/7 defense and energy security. Sales of €1,890 million for the first nine months of 2026 reflect demand for these long-life assets. Investor returns may depend on how pressure on profitability influences the economics of future contracts.

Those contract economics are already shifting. Read the analysis report for TKMS & Co KGaA to see how TKMS & Co KGaA’s order book could reshape the quality of future earnings.
