The quantity of natural uranium amounts to almost 770 tonnes, when it had stabilized around 1000 tonnes between 2020 and 2022. It had almost doubled in 2020. As for the weakly enriched uranium, the stock rises to almost 141 tonnes. It was 113.6 tonnes a year earlier.
-Apparatus uranium (8 kg) and plutonium (1 kg) have not changed since 2017. Switzerland does not store thorium or highly enriched uranium abroad. As for uranium stocks from reprocessing, they were deleted in 2020.
The stocks of Swiss nuclear materials are located in Germany, France, Great Britain, the United States, Spain and Sweden, the Federal Energy Office (OFEN) said in a statement on Thursday. Their variations result from the acquisition and transformation of uranium into combustible elements, according to economic requirements and requirements related to exploitation.
Since the entry into force of the nuclear energy law and the order on the application of guarantees, all stocks of Swiss nuclear materials abroad must be declared each year to the supervisory authorities.
