The EPR is a Generation III+ pressurised water reactor design. It has been designed and developed mainly by Framatome (part of Areva between 2001 and 2017) and Électricité de France (EDF) in France, and by Siemens in Germany.[1] In Europe this reactor design was called European Pressurised Reactor, and the internationalised name was Evolutionary Power Reactor, but is now simply named EPR.

The first operational EPR unit was China's Taishan 1, which started commercial operation in December 2018.[2] Taishan 2 started commercial operation in September 2019.[3] European units have been so far plagued with prolonged construction delays and substantial cost overruns. The first EPR unit to start construction, at Olkiluoto in Finland, originally intended to be commissioned in 2009, started commercial operation in 2023, a delay of fourteen years.[4] The second EPR unit to start construction, at Flamanville in France, also suffered a more than decade-long delay in its commissioning (from 2012 to 2024).[5] Two units at Hinkley Point in the United Kingdom received final approval in September 2016; the first unit was expected to begin operating in 2027,[6][7] but was subsequently delayed to around 2030.[8]

EDF has acknowledged severe difficulties in building the EPR design. In September 2015, EDF stated that the design of a "New Model" EPR (later named EPR2) was being worked on and that it would be easier and cheaper to build.[9]
