The Äspö HRL (hard rock laboratory) outside Oskarshamn is a unique facility. SKB is conducting full-scale research and development here in preparation for the construction of a final repository for spent nuclear fuel.
Microbial studies have been done for almost three decades at Äspö HRL by national as well as international groups.
There are various ways to protect the anaerobic samples. This is one of them.
