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 by Areva.

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 2016 and 2017.

Design

The main design objectives of the third generation EPR design are increased safety while providing enhanced economic competitiveness through improvements to previous PWR designs scaled up to an electrical power output of around 1650 MWe (net) with thermal power 4500 MWt. The reactor can use 5% enriched uranium oxide fuel, reprocessed uranium fuel and 100% mixed uranium plutonium oxide fuel. The EPR is the evolutionary descendant of the Framatome N4 and Siemens Power Generation Division "Konvoi" reactors.

EPR1

Effector cell peptidase receptor 1, also known as EPR1, is a human gene.

This locus represents an antisense transcript of the survivin locus.This record was withdrawn in collaboration with HGNC. It was defined by L26245.1, which appears to be a cloning artifact (PMID 10891443).(This information come from http://www.ncbi.nlm.nih.gov/gene?term=L26245.1)
