The Nogent Nuclear Power Plant is located in the French commune of Nogent-sur-Seine, on the right bank of the Seine, in the west of the Aube department.

The plant houses two reactors each of 1300 MWe and the site has a total area of 100 hectares.

It produces about a third of the yearly electricity consumption of Île-de-France and employs around 700 regular workers.

On 5 December 2011, nine Greenpeace anti-nuclear activists cut through a fence at the Nogent Nuclear Power Plant.

They scaled the roof of the domed reactor building and unfurled a "Safe Nuclear Doesn't Exist" banner before attracting the attention of security guards.
