Radioactive waste disposal Switzerland

Regulatory objectives and safety requirements for the disposal of radioactive wastes in Switzerland... 

The risks to humans and the environment arising from radioactive waste disposal in Switzerland shall not, at any time in the future and anywhere abroad, exceed the levels which are permissible today in Switzerland. 

Although evidence from natural systems is useful to constrain reaction mechanisms and minerals to be incorporated into such models, time-dependent information is generally lacking. A series of laboratory column experiments have been conducted as blind test cases in order to test the capabilities of two of the currently available, coupled models to predict product solids and output fluid compositions with time. The experiments reacted single minerals of importance to the radioactive waste disposal programmes in the UK, Sweden and Switzerland, with simplified young (Na-K-Ca-OH) and evolved (Ca(OHE) synthetic cement porewater leachates.

During the last 15 years much progress has been made in radioactive waste management in Switzerland including development of specific disposal concepts and implementation of different site evaluation programmes. For the realization of final repositories for low- and high-level wastes, substantial amounts of further work are still required.
