Global certainty for generations to come

AREVA's EPR™ reactor, is the first Generation III+ PWR reactor design currently being built to answer the world's growing demand for clean and reliable electricity generation.
Under construction in Finland, France and China, the EPR™ reactor is also being considered by America, United Kingdom, India ... and other countries for the development of their nuclear fleet.

A safe and evolutionary design

The EPR™ reactor is a 1,650 Mwe pressurized water reactor (PWR). The PWR technology is the most widespread (in late 2005 it represented 56% of operational reactors) and AREVA has mastered it perfectly: the group has built 87 PWR reactors in 11 countries of which 84 are still in operation.

AREVA’s EPR™ design incorporates unbeatable know-how provided by an uninterrupted track record of reactor building activities and backed by more than two thousand years of feedback experience from operating PWRs, including the most recent.

A leader in state-of-the-art technology

The EPR™ reactor boasts the following evolutions:

An axial economizer inside each steam generator allows a higher level of steam pressure and plant efficiency.
A heavy neutron reflector surrounding the reactor core lowers uranium consumption.
An outer shell covering the reactor building, the used fuel building and two of the four safeguard buildings provides protection against a large commercial or military aircraft crash.
A core catcher allows passive collection and retention of the molten core should the reactor vessel fail in the unlikely event of a core melt.
Digital technology and a fully computerized control room with an operator-friendly human-machine interface improve the reactor protection system.
