EPR Reactor- In a nutshell
EPR is the name of AREVA's Generation III + high power output Pres~surized Water Reactor (PWR).
The EPR reactor was purpose-designed to satisfy the
demands of electrical utility companies for a new gen
eration of nuclear power plants that offers increased
levels of safety and competitiveness today while more effi
ciently meeting the energy requirements of tomorrow. As a
result, the EPR reactor showed an "excellent level of compli
ance" during its 2009 review by a group of major Europeanelectricity producers, demonstrating over 99.9% conformity
with the criteria detailed in the European Utilities Require
ments (EUR) document.
From paper to concrete: Four EPR reactors are already
under construction: One in Olkiluoto, Finland, one in Flaman
ville, France and two inTaishan, China. Additionally, the United
States, the United Kingdom and India are currently perform
ing licensing or pre-licensing for their own EPR reactor pro
grammes.
An impeccable pedigree: The EPR design is the fruit of de
cades of advanced R&D programmes, in particular those at the
CEA (French Atomic Energy Commission) and the Karlsruhe
Research Center in Germany. It is a direct descendent of the
tested and proven N4 and KONVOI reactors from Framatome
and Siemens/KWU, the most modern and most powerful reac
tors in France and Germany. Moreover, the EPR was designed
using input obtained directly from both French and Germansafety authorities and has benefited from these authorities' co-
operation and indeed active involvement from the very earli
est phases of its conception. As a result, the EPR reactor is
optimised to meet the higher safety requirements of the new
generation of nuclear power plants while offering very compet
itively priced electricity generation. Dozens of pages could be
written on the state-of-the-art features of the EPR reactor. For
the purposes of a document of this kind, however, it is sufficientto note that the EPR reactor is indisputably at the forefront of
nuclear power plant design and safety.
The EPR reactor and India: Having already poured the
concrete for this new generation of nuclear reactors in Fin
land, France and China, AREVA offers NPCIL the invaluable
benefits of lessons learned - including vital experience with
streamlined construction, standardized /fine-tuned engineer
ing, licensing know-how and global optimised supply chains.

Safety and minimised risks, first and foremost: The EPR
reactor's pedigree provides utilities with a solid assurance of
minimised licensing risks and thus a seamless management and
smooth execution of the project. It also brings the surround
ing population the knowledge that early and intense scrutiny
of the EPR reactor's design has resulted in unprecedented levels of safety for them and for the environment.
