Flamanville 3

Flamanville 3 is the First Of A Kind EPR in France - Generation III+ reactor and the 100th reactor ordered from AREVA.

It is part of the French nuclear fleet renewal program. This is aimed at renewing the country's nuclear heritage before gradually dismantling the oldest facilities as of 2020.

Since the end of 2007, teams from AREVA NP have been working on this site belonging to EDF, a world leader in nuclear energy. The largest industrial project in Northern Europe along with Olkiluoto 3 in Finland, Flamanville 3 brings together the expertise of over 4,000 people from 55 different countries.
