Nuclear energy stocks are back in focus as Europe searches for more reliable electricity.
France’s EDF plans to develop 10 small modular reactors, or SMRs, across the EU by 2035.
The goal is simple:
more electricity + less dependence on imported fossil fuels + stronger energy security.
What Is a Small Modular Reactor?
An SMR is a smaller nuclear reactor designed to be easier to build than a traditional large nuclear plant.
EDF’s planned reactors would produce around 400 megawatts each.
That is much smaller than a large conventional nuclear station, but still enough to provide substantial electricity or industrial heat.
The idea is to build reactors in a more standardized way instead of designing every nuclear plant almost from scratch.
Why Europe Needs More Power
Europe’s electricity demand is growing.
The main drivers include:
- AI data centers
- electric vehicles
- industrial electrification
- heat pumps
- lower use of fossil fuels
The IEA says electricity demand is now growing about three times faster than total energy demand globally.
Europe also faces high electricity prices and limited grid capacity.
That means producing enough reliable power is becoming an economic issue, not just an environmental one.
Why Nuclear Is Attractive
Nuclear power has one major advantage:
it can generate electricity continuously.
Wind and solar depend on weather conditions.
Nuclear plants can produce power day and night.
That makes nuclear useful alongside renewables, especially when electricity demand from data centers and industry keeps rising.
France already gets around 70% of its electricity from nuclear power, giving EDF significant experience in the sector.
Why SMRs Could Be Different
Traditional nuclear plants can be extremely expensive and take many years to build.
SMRs aim to reduce those problems.
Potential advantages include:
Smaller projects
Less capital may be required for each individual reactor.
Standardized construction
Using similar designs repeatedly could reduce costs.
Industrial heat
SMRs could supply heat directly to factories as well as electricity.
Flexible locations
Smaller reactors could potentially be built closer to industrial demand.
EDF expects electricity from its proposed reactors to cost around €100 per megawatt hour, which it says could compete with gas-fired generation.
Where Could EDF Build Them?
The first reactor is expected in France.
EDF also plans one in Italy, working with companies including Edison, Saipem and Webuild.
The company is exploring opportunities in:
- Poland
- Belgium
- Finland
Italy is particularly interesting because it is moving toward allowing nuclear power again after nearly four decades without it.
Why Nuclear Energy Stocks Could Benefit
A European SMR buildout would create demand across a wide supply chain.
Potential beneficiaries include companies involved in:
- uranium
- nuclear fuel
- reactor equipment
- engineering
- construction
- turbines
- electrical systems
The broader nuclear revival is already increasing pressure on uranium supply and enrichment capacity.
The U.S. Department of Energy recently warned that enrichment capacity needs to expand faster to avoid shortages as global nuclear demand rises.
That means Europe’s SMR plans fit into a much larger global nuclear trend.
But SMRs Still Need to Prove Themselves
The biggest risk is execution.
SMRs sound cheaper and faster in theory, but relatively few commercial projects have been completed at scale.
Projects still face:
- regulatory approval
- financing
- construction delays
- nuclear-waste concerns
- public opposition
EDF itself previously scaled back a more ambitious SMR design because of cost and complexity concerns.
So the important question is not simply whether Europe announces more reactors.
It is whether they can actually be built on time and at a competitive cost.
What Should Investors Watch?
The key signals are SMR approvals, construction costs, EDF project timelines, uranium prices and European electricity demand.
The central question is simple:
Can Europe build nuclear capacity faster than its electricity demand grows?
If EDF proves that SMRs can be built economically and repeatedly, small nuclear reactors could become an important part of Europe’s energy system.
If costs and delays remain high, the technology may struggle to deliver on the promise.
