What is an EPR?
EPRs – originally known as European Pressurised Water Reactors – are a type of Pressurised Water Reactor (PWR). The design of the UK EPRs that will be built at Hinkley Point C represents a major development on previous PWRs, making them amongst the safest and most efficient civil nuclear power generators ever designed.
The UK EPR design marks significant progress towards sustainability. It has been designed to use less uranium and produce almost a third less long-lived radioactive wastes compared with water reactors in operation today.
Tailored for the UK
The UK version of the EPR meets the most stringent safety standards, having gone through the UK’s rigorous, four-year Office for Nuclear Regulation (ONR) Generic Design Assessment (GDA) process.
Since we want Hinkley Point C to be a world leading nuclear power station, EPR technology is the obvious world leading choice to power it.
The EPR turns the nuclear energy in uranium atoms into electrical energy that can be used in homes and businesses. When the nucleus of an atom is split (nuclear fission), the heat produced turns water into pressurised steam, which turns turbines and generates electricity.

The EPR's large core means it uses 17% less uranium than older technology
separate safety systems in the EPR protect against all hazards, including earthquakes and flooding
