Georges Besse II Uranium Enrichment Plant, Bollène, France: Visiting Hours, Tickets, and Guide
Date: 04/07/2025
Introduction
The Georges Besse II Uranium Enrichment Plant, located near Bollène in France’s Tricastin region, is a landmark of European nuclear technology and energy independence. Named for the influential engineer Georges Besse, the facility marks a generational leap in uranium enrichment, moving from the old, energy-intensive gaseous diffusion process to modern gas centrifuge technology. This evolution has drastically reduced the plant’s energy consumption and environmental impact, underscoring France’s commitment to sustainable nuclear energy (Orano Group; World Nuclear Association).
Since its launch in 2010 and full commissioning in 2016, Georges Besse II has provided enriched uranium to France’s 56 nuclear reactors, which generate roughly 70% of the nation’s electricity (IEA France 2023 Review). The plant is currently undergoing a EUR 1.7 billion expansion to boost capacity by over 30% by 2030, a move that strengthens both European energy resilience and climate goals (World Nuclear News; Orano Group).
Due to the sensitive nature of its operations, public visits to Georges Besse II are not permitted, but educational and professional groups may apply for guided tours under strict protocols (ASN France). For the general public, Orano and partners offer virtual tours and interactive resources, allowing remote exploration of the plant’s technology and significance (Discovery Alert; World Nuclear News).
Visitors to the area are encouraged to discover Bollène’s cultural highlights, including medieval castles, museums, and scenic landscapes (Bollène Tourism). The combination of advanced nuclear engineering and regional heritage makes for a compelling, educational experience.

Origins and Historical Development
The Georges Besse II plant honors Georges Besse, a key figure in French nuclear engineering and former Eurodif CEO. Its predecessor, the Eurodif gaseous diffusion plant, operated from 1979 and was central to Europe’s uranium enrichment efforts. In the early 2000s, the need for efficiency and sustainability led to the development of Georges Besse II, which broke ground in 2006. By 2010, the first cascades were operational, and by 2016, the plant was running at full capacity (Orano Group; World Nuclear News).
Transition to Centrifuge Technology
The transition from gaseous diffusion, which consumed approximately 2,700 MW, to gas centrifuge technology, using around 50 MW for the same capacity, marked a dramatic advancement (World Nuclear Association). In centrifuges, uranium hexafluoride gas is spun at high speed, separating uranium-235 from uranium-238 far more efficiently and with a greatly reduced environmental footprint.
Role in the French and Global Nuclear Industry
Operated by Orano (formerly Areva), Georges Besse II is a linchpin of France’s closed nuclear fuel cycle, supplying enriched uranium to all domestic reactors and serving international clients (IEA France 2023 Review; Orano Annual Report). The plant’s capacity of 7.5 million SWU places it among the largest in the world, supporting both national energy independence and global nuclear supply chains.
Technological Innovations and Environmental Impact
Georges Besse II’s modular design, advanced automation, and digital controls ensure operational efficiency and safety. The plant reduces greenhouse gas emissions by roughly 90% compared to its predecessor, thanks to lower power requirements and France’s predominantly nuclear-generated electricity. Robust containment and continuous monitoring systems uphold high safety standards (ASN France).
Strategic and Economic Significance
As France’s core uranium enrichment facility, Georges Besse II underpins national energy security and reduces reliance on foreign sources (Orano Group). The plant also contributes to the French economy by supporting thousands of jobs and generating export revenue. Compliance with IAEA safeguards ensures adherence to international non-proliferation standards (IAEA France).
Visiting the Georges Besse II Uranium Enrichment Plant and Bollène Historical Sites
Visitor Access and Tours

Visiting Hours and Tickets
There are no standard public visiting hours or ticket sales, reflecting the plant’s operational and security priorities. Interested parties should use virtual tours and educational materials available through Orano’s website.
Nearby Attractions and Bollène Historical Sites
Bollène offers a wealth of historical attractions, including the medieval Bollène Castle, local museums, and scenic old town streets (Bollène Tourism). These sites provide cultural context and complement the region’s technological achievements.
Travel Tips
Bollène is accessible by train or car from Avignon and Orange. Visitors can combine a regional trip with virtual exploration of Georges Besse II, making for a rewarding blend of science and culture.
Expansion, Strategic Context, and Visitor Information
Expansion Project Overview
A EUR 1.7 billion expansion, approved in 2023, is underway to add four new centrifuge modules, raising capacity from 7.5 to approximately 10 million SWU by 2030 (World Nuclear News; Orano Group). This move is foundational to Europe’s energy independence and climate neutrality, especially as the continent seeks alternatives to Russian nuclear fuel.
Strategic Importance
The expansion is backed by a EUR 400 million loan from the European Investment Bank and complies with Euratom and European Commission regulations (Orano Group). It will help supply low-carbon electricity to as many as 120 million households and fortify European energy security.
Technology, Environmental Features, and Timeline
The new modules will build on Georges Besse II’s established energy efficiency and environmental performance. Construction and operation will adhere to stringent safety and sustainability standards, with phased commissioning through 2030.
Key Milestones:
- September 2023: Project formally notified under Euratom Treaty.
- October 2023: Investment approval by Orano’s board.
- October 2024: Foundation stone laid (Orano Group).
- March 2025: EIB loan agreement signed.
- 2028: Initial operations of new modules expected.
