Very-low-level waste repository

The CSTFA very-low-level waste repository (located at Morvilliers in the Aube district) has been commissioned in August 2003. Its overall capacity is 650,000 m3.

At the end of 2007, the volume of waste disposed of was about 91,300 m3. Waste is disposed of in special vaults excavated in a clay formation and protected by a synthetic membrane and, in the future, by a clay cover.

This disposal facility is operated by Andra.

A few figures:

• Siting & construction cost: 40M Euros
• Operational mean cost: 270 Euros/ton
