ISN – Interim Storage Facility North
A central component of EWN’s disposal concept for dismantling the nuclear plants in Greifswald/Lubmin and Rheinsberg is the use of the Interim Storage Facility North (ISN) for storing nuclear fuel and the interim and decay storage and processing of accumulated radioactive residual materials and waste.
Both the waste store and the transport container store are housed in ISN’s storage building. Nuclear fuel, waste containing nuclear fuel, low and medium-level contaminated residual materials and waste are stored temporarily in eight storage buildings which are connected along the front side by a loading hall.
The long-term plan is for the nuclear fuel and the waste containing nuclear fuel currently in the Interim Storage Facility North to be moved to a federal final storage facility for heat-generating radioactive waste. The residual radioactive substances remain in the ISN until they can be moved to the KONRAD final storage facility or recycled conventionally or disposed of in landfill after processing and cleaning and subsequent official approval.
As a processing station, the ISN is designed so that, with the exception of nuclear fuel, almost all accumulating radioactive waste and waste can be processed. With the other facilities at site, i.e. the Central Active Workshop and the Central Decontamination and Water Treatment Plant, the conditioning and treatment of radioactive waste and waste will be separated spatially and temporally from the dismantling activities.
The ISN waste storage facility has a permit under the Radiation Protection Ordinance for the handling of other radioactive substances. Approval authority is the responsible Ministry of the Land Mecklenburg-West Pomerania.
