Nuclear power plants may be sited in underground caverns, on slopes, or in pits. When a possible site is being considered, geoengineering and rock mechanical factors must be considered with respect to the feasibility of construction and the protective effect of the surrounding rocks as a barrier against internal accidents and external hazards.
The Federal Institute for Geosciences and Natural Resources carried out a preliminary evaluation of suitable sites in Germany in the 1980's using geoengineering and rock mechanical criteria. Three suitable rock types were defined: quartzite, schist and New Red Sandstone. These theoretical studies must be supplemented by in situ measurements, especially with respect to the efficiency of the rock as a geological barrier.
