Due to the Swiss moratorium against the export of spent nuclear fuel in 2006 it was necessary to store
the spent fuel locally at the nuclear power plant site. The prolongation of this moratorium in 2016
does not allow reprocessing of spent fuel in the next years. As a direct conclusion from this moratorium
it was decided to build a wet storage pool at Gösgen/Däniken which entered operation in 2008 with a capacity
of 504 fuel assemblies. In a second stage of completion another 504 fuel assemblies can be stored in the pool.
Two cooling towers will be available for the cooling of the wet storage pool with a maximum cooling capacity of
1.5 MW after the second stage of completion.
The wet storage building of the nuclear power plant Gösgen/Däniken is the first building for the long term wet storage of spent nuclear fuel in Switzerland. For the estimation of time windows for accident management measures PSI has done several calculations with the MELCOR code under loss of cooling conditions for different loading patterns in the wet storage pool.
