Meuse/Haute Marne Underground Research Laboratory

The Meuse/Haute Marne Underground Research Laboratory is a scientific facility roughly 500 meters beneath the surface with extensive tunnels for studying rock formations and storage capabilities. The above-ground installations contain research buildings and transport systems that serve the underground operations.

Construction of this scientific facility began in 1999 under the direction of Andra, the French nuclear waste management agency, to research deep geological disposal methods. The project has since become one of Europe's leading research sites for long-term radioactive waste storage.

The facility engages with local residents through guided tours and educational events that explain how radioactive materials can be safely stored deep underground. Visitors gain insight into the scientific thinking behind long-term safety and environmental responsibility.

Two main shafts provide access to the underground sections, where visitors can explore the network of tunnels and research spaces. It is advisable to wear comfortable clothing and prepare for cool, steady temperatures underground.

The facility focuses on Kimmeridgian claystone, an ancient rock layer that may safely isolate nuclear waste for thousands of years. Scientists use this location to test how well this natural material withstands heat radiation and chemical reactions over extremely long timescales.
