Description

The Felslabor Grimsel (Grimsel Test Site GTS) is an underground laboratory established by the Swiss National Cooperative for the Disposal of Radioactive Waste. It is located underground inside the famous Grimsel granite. It was established for scientific research concerning the safe management and disposal of radioactive waste.

In Switzerland, the producers of this waste are responsible for its safe disposal. So the NAGRA is a joint venture of the Swiss Federal Government and half a dozen corporations which are involved in nuclear sciences. This institution established and manages several underground nuclear laboratories. This one is open to the public.

The laboratory is rather close to the hydro-electric electric power plant. The reason is easy: the power plant needed numerous underground tunnels, which were reduced to minimize costs of this laboratory. The site is not intended for the disposal of radioactive waste.
