|ILW-LL waste disposal cell|
The diagram provides an overview of the design and architecture of an intermediate-level long-lived waste repository. In the bottom right, primary waste packages are visible inside a concrete disposal package. The disposal packages' cube shape allows them to be stacked in long disposal cells, which would only be sealed when the facility was closed. The disposal cells in a given module extend into the rock in a parallel formation, and are connected to an access tunnel.
