EPR may refer to:

EPR (nuclear reactor)

The EPR is a third generation pressurized water reactor (PWR) design. It has been designed and developed mainly by Framatome (now Areva NP) and Électricité de France (EDF) in France, and Siemens in Germany. In Europe this reactor design was called European Pressurized Reactor, and the internationalized name was Evolutionary Power Reactor, but it is now simply named EPR.

Four EPR units are under construction. The first two, in Finland and France, are both facing costly construction delays (to at least 2018). Construction commenced on two Chinese units in 2009 and 2010. The Chinese units were to start operation in 2014 and 2015, but are now expected to come online in 2017. Two units at Hinkley Point in the United Kingdom have been approved by stakeholders EDF and CGN, but are awaiting final government approval.

EDF has acknowledged severe difficulties in building the EPR design. In September 2015 EDF stated that the design of a "New Model" EPR was being worked on, which will be easier and cheaper to build.
