Abstract
Abstract In Sweden, researchers are examining designs for a repository for storage of spent nuclear fuel. By the year 2010 (when nuclear power production will cease, according to parliamentary decision), approximately 10,000 m 3 of spent fuel will need to be encapsulated in the repository. One such system, the KBS-3 (abbreviation for Nuclear Fuel Safety, in English), has been evaluated over the past decade. Another design, called the Very Long Hole (VLH) system, is also being considered. The main difference between the two systems is in the shape of the rock openings in the disposal areas. This paper analyzes the properties of the rock in the near field (i.e., the rock affected by the excavation of the repository) and compares them for the two repository systems.
