Swiss nuclear power and the case for long-term operation
Designed for 40 years but built to last far longer, Switzerland’s nuclear power plants have all entered long-term operation. Yet age alone says little about safety or performance. Through continuous upgrades, strict regulatory oversight, and extensive aging management, the country’s reactors are being prepared for decades of continued operation, in line with international practice.

One of the two German spent-fuel management options envisages the direct (i.e., no reprocessing) final disposal of spent-fuel assemblies from nuclear reactors in a geological repository. The reference repository will be located in a salt dome. The spent fuel will become inaccessible immediately after its emplacement in drifts, and this rules out a retrieval of the nuclear material from the repository. The Nuclear Non-Proliferation Treaty requires compliance verification by inspection regimes. A safeguards approach has been developed for the German reference disposal concept, which would be applicable today and which would meet the requirements of the International Atomic Energy Agency as well as the recommendations of the 1995 Consultants Meeting on Safeguards for Geological Repositories. It foresees cask verification in the aboveground area (material balance area I) and design information verification in the aboveground and belowground (material balance area II) areas of the repository. Safeguards have to continue even after closure and decommissioning of the repository mine.
