460 metres.
• Improve our scientific understanding of the deep repository’s safety margins and gather data
for assessments of long-term safety.
• Train personnel for execution of various parts of the deep repository project.
• Provide information on technology and methods that are being developed for the deep
repository.
According to the plans, the activities at the Äspö HRL, which are largely being pursued in
collaboration with other countries, will continue until the initial operation of the deep repository
is concluded. The evaluation of the results of initial operation and of ongoing experiments in
the Äspö HRL will serve as a basis for an application for a licence for regular operation of the
deep repository. An important role for the Äspö HRL in this perspective is therefore to conduct
long-term experiments where different aspects of the function of the deep repository are tested
over a long period of time, in some cases 15–20 years.
Activities are being conducted within the following areas:
• Natural barriers (mechanical, hydrological and chemical properties of the rock).
• Engineered barriers (buffer and backfill).
• Deep repository technology (rock extraction, design, handling technology).
The different experiments and development projects being pursued in the Äspö HRL are
presented in this programme under the appropriate research heading. An overview of the
experiments and their location is provided in Figure 1-3.
Äspö research school
In 2002 the University of Kalmar established an environmental science research school with
activities at the Äspö HRL. A professor is associated with the school, and four doctoral candidates
where working there at the beginning of 2004. SKB and Oskarshamn Municipality are
