Nuclear power plants in France in 2023

Please share:

France’s nuclear power plants comprise 56 reactors at 18 strategically located sites across the country. These facilities are crucial to the country’s energy economy, supplying a substantial proportion of the electricity consumed. Among these emblematic sites, the Flamanville nuclear power plant is particularly well known for its plans to build a third-generation EPR (European Pressurized Reactor) reactor.

Nevertheless, the project has been plagued by various delays and technical complications, raising questions about the safety and reliability of France’s entire nuclear fleet.

However, the government, led by Emmanuel Macron, maintains a firm commitment to this energy source with the creation of new reactors, its Acceleration Bill and ongoing investment in modernization and safety projects.

Where are France’s 19 nuclear power plants?

France’s energy landscape is dominated by nuclear power plants, with a total of 19 facilities spread across the country. These power plants play a crucial role in electricity generation in France, supplying around 70% of the energy consumed.

However, the location of these nuclear power plants remains a matter of concern for many citizens, especially those living nearby. France’s nuclear power plants are mainly located along the coast, near major rivers or in remote areas. This ensures an adequate supply of water for cooling the reactors, and minimizes risks in the event of an accident.

France’s largest nuclear power plants include :

Flamanville, Gravelines, Paluel and Penly are all located along the northern coast of France. These plants have several reactors and are capable of producing large quantities of electricity.

The Cattenom nuclear power plant, near the border with Luxembourg and Germany, is also one of the country’s main facilities. Other nuclear power plants are located near major rivers such as the Loire, Garonne and Rhône. These include the Belleville, Chinon, Saint-Laurent, Bugey and Tricastin power plants. Thanks to the proximity of these watercourses, power plants can benefit from an adequate water supply and an efficient cooling system.

Finally, some nuclear power plants are located in remote areas of France, such as the Fessenheim plant in Alsace. The plant is one of the country’s oldest, and is due to be shut down in the coming years, in line with the government’s objective of reducing France’s dependence on nuclear power.

Flamanville nuclear power plant

Flamanville nuclear power plant

The Flamanville power plant in Normandy is a nuclear facility that uses an EPR (European Pressurized Reactor) to generate electricity. The construction program at Flamanville, known as Flamanville 3, began in 2007, but has been subject to numerous delays and technical problems. The Flamanville EPR was originally scheduled for commissioning in 2012, but due to these problems, the commissioning date has been pushed back several times. The site’s rising costs and construction times have been the subject of much criticism and controversy.

Power

The FlamanvilleEPR is designed to deliver 1,650 megawatts of power, making it one of the most powerful reactors in the world. However, due to construction delays and technical problems, it is difficult to say exactly when the plant will be fully operational. What’s more, the exact price of the Flamanville EPR is also controversial. Initially estimated at 3.3 billion euros, the cost of construction has risen significantly over the years. According to some estimates, the total cost of the Flamanville EPR could reach up to 12.4 billion euros, making it one of the most expensive reactors ever built.
The Flamanville power plant is currently undergoing pre-commissioning tests and trials. Once fully operational, it should supply a significant proportion of the electricity required by the Normandy region. Despite past difficulties, the Flamanville plant represents an example of perseverance and determination in the pursuit of new-generation nuclear power in France.

Nuclear safety in France is a major concern

The French Nuclear Safety Authority (ASN) rigorously supervises the safe operation of nuclear facilities in France. France currently operates 56 nuclear reactors, mostly pressurized water reactors, in 18 power plants. These facilities are managed by Électricité de France (EDF) and closely monitored by ASN.

In terms of regulation, strict laws govern the safety and security of the nuclear sector in France.

All reactors, whether under construction or already operational, must comply with the safety standards defined by the ASN. Compliance with these guidelines is vital to the long-term future of the nuclear industry, which plays a key role in the country’s energy supply.

In short, nuclear safety in France is a government priority, and multiple players, including ASN and EDF, work in synergy to ensure the safe operation of nuclear facilities. It is imperative to refer to up-to-date data for accurate information, as the sector is constantly evolving.
