Emission-free nuclear

UK nuclear revival helps bring about energy independence

The UK’s electricity grid is in a state of transition as Parliament has set the ambitious goal of cutting the nation’s greenhouse gas emissions to zero by 2050. With much of its current nuclear fleet fast-approaching end-of-life, modern innovations like GEH’s BWRX-300 small modular reactor (SMR) promise to help the UK deliver on its net-carbon-zero promise and become energy independent.


The solution to climate change is not living with less energy. The solution is embracing better technology, which must include nuclear energy.

SMR benefits

Smarter, safer, faster, more economical

GEH’s BWRX-300 represents the latest evolution of the economic simplified boiling water reactor (ESBWR). Melding proven ESBWR technology with advanced construction solutions and innovative building techniques results in a SMR that is smarter, safer, faster to construct, and less costly to operate.

Innovative construction

Modular and open-top construction enables a BWRX-300 to be built in 24–36 months with 50% less concrete.

Proven technology

Built on a 60+-year legacy of developing BWR nuclear reactors currently operating around the globe.

Economical advantages

Offers up to 60% less capital cost per MW compared to large reactors and even other SMR designs.

Frequently asked questions

Certainty comes with experience

Is nuclear power a clean energy technology?

Nuclear’s carbon footprint is miniscule compared to fossil fuels. In fact, if all the world’s coal and natural gas plants were replaced with low-carbon nuclear, global CO2 emissions would be reduced by nearly 13 billion tons annually.

Does the UK use nuclear power now?

Yes! There are nine operating commercial nuclear power reactors at five nuclear generating stations in the UK which, in 2022, produced 5.9 GWe—approximately 16% of the UK’s electricity. However, at its peak capacity in 1997, 26% of the UK’s electricity came from nuclear energy. Four of those reactors are slated for closure by the year 2030.

Will a nuclear power plant take up a large amount of land?

Nuclear is already the most land-efficient means of electricity production, requiring only 2.4 km²/TWh per year. However, an SMR like the GE Hitachi BWRX-300 is also designed to reduce building volume in plant layout by about 90 percent, resulting in a minimal impact on natural habitats compared to fossil fuels.

Is nuclear power safe?

Many countries have safely used nuclear power for well over 60 years. It is one of the most closely monitored and regulated industries in the world and actually has the lowest rate of fatalities and injuries per unit of electricity compared to all other electric power generation. Cyber security and physical on-site security are top-tier and on guard 24/7/365.

The reactors themselves are built to strident safety specifications, constantly monitored, and layered with multiple redundancy systems to maintain the unprecedented track record of safety the industry has achieved.

How is the nuclear energy industry regulated in the UK?

The Office for Nuclear Regulation (ONR) is the UK’s nuclear regulator. It is an independent agency with legal authority to regulate nuclear safety, civil nuclear security and safeguards, and—at authorized defense sites—conventional health and safety at the licensed British nuclear sites.

The ONR ensures that security arrangements are adequate for dealing with special nuclear material and information. It also regulates the transportation safety and security of civil nuclear and radioactive materials by road, rail, and inland waterways.
