Rolls-Royce share price analysis now turns on a simple split: most of the group still earns money from Civil Aerospace, Power Systems and Defence, but a smaller nuclear arm could become a bigger driver later. Rolls-Royce Holdings designs nuclear powered submarine reactors, and Rolls-Royce SMR is already moving beyond the concept stage.
That matters because the group generates £11.8b from Civil Aerospace, £5.5b from Power Systems and £5.0b from Defence, while only part of that business is linked to nuclear propulsion. For investors looking at British nuclear exposure, the share price case depends on whether the reactor work becomes a meaningful extra revenue stream rather than a side line.
Rolls-Royce SMR in three countries
Rolls-Royce SMR has already secured multi-country selections and is in execution for units in the UK, Sweden and the Czech Republic. The plan reaches a first production step in the mid 2030s, when it aims to commission up to 2 small modular reactors per year.
At maturity, that target rises to up to 8 per year. That is the scale that could change how the market values the nuclear business, because it points to recurring output rather than a one-off project pipeline.
UK energy pressure lifts nuclear focus
The wider backdrop is tighter interest in low carbon power as energy bills across the UK come under pressure and European oil import costs rise sharply. In that setting, nuclear assets are being treated less as a niche and more as a supply and pricing hedge.
Centrica fits that theme from a different angle. It supplies power and services, including electricity generated from nuclear assets, and it generates about £16.3b from Retail, £6.0b from Optimisation and £1.6b from Infrastructure.
Kazatomprom and fuel supply
National Atomic Company Kazatomprom JSC adds another route into the sector through uranium rather than reactors. The Kazakhstan based producer supplies natural uranium fuel and related products to global nuclear utilities, and The Uranium segment generates about KZT 1,697,002 million of revenue.
Ulba Metallurgical Plant and other activities contribute smaller amounts across diversified products and services. For Rolls-Royce, though, the investment case is narrower and more direct: the market is watching whether the SMR buildout can scale fast enough for the nuclear arm to matter alongside the group’s much larger aerospace and power businesses.
