ILW-LL (Intermediate level) waste repository
The intermediate-level long-lived waste repository would be divided into two sections, or sub-zones, one of which designated for waste packages containing organic matter, the other for packages that do not, such as compacted waste packages. The purpose of this distinction is to mitigate the consequences (in particular the release of hydrogen) of long-term decomposition of organic matter under the effect of radiation.
