Cattenom Nuclear Power Plant

Cattenom Nuclear Power Plant  ( French: Centrale nucléaire de Cattenom ) is located in Grand Est in the Cattenom commune, France, on the Moselle River. between Thionville (7 km upstream) and Trier (48 km downstream).

It is close to the city of Luxembourg (22 km) and Metz (32 km).

This nuclear power plant consists of 4 pressurized water reactors, all of which were built between 1979 and 1991, each generating 1300 MW, and the total Installed capacity is 5,200 MW. The power plant is a relatively modern large nuclear power plant.

In 2019, its power generation was second only to Gravelines Nuclear Power Station and Paluel Nuclear Power Plant in French.

This nuclear power plant employs approximately 1,200 regular employees and approximately 1,000 employees during the power outage.

Cattenom Nuclear Power Plant obtained ISO 14001 certification in 2005 and ISO 9001 and OHSAS 18001 in 2007.

The Cattenom nuclear facility uses water from the Moselle River.

It uses 4 independent cooling towers, which use 890,000,000 m³ (3.1 × 10¹º cubic feet) of water from the Moselle River each year.

In addition, the Mirgenbach lake water reserve was established on site. The creation of this lake has led to the flooding of the subterranean portions of Ouvrage Kobenbusch, part of the Maginot Line. In 1985 an artificial lake was also created in the Pierre-Percée valley in the Vosges.

During the 2003 European heat wave, the factory was allowed to send the waste water used for cooling directly to the Moselle River.

Three condensers of the plant were removed and retubed in 2019, which involved the replacement of a total of 64,200 tubes.
