Bure underground laboratory
The underground laboratory in Bure, on the boundary between the Meuse and Haute Marne departments features surface facilities extending over approximately 17 hectares as well as 1 kilometre of underground installations excavated directly into the Callovo-Oxfordian clay formation, 445 and 490 metres underground. These deep-lying clay layers in the Paris Basin are impermeable and very stable, making them candidates for disposal of long-lived high-level waste with effect from around 2020.
