12 ILW INTERIM STORAGE FACILITIES
12.1 Introduction
ILW generated by the operation of the EPR will be stored in an Interim Storage Facility (ISF).
The ISF is located separately from the WTB and will continue to provide interim storage for ILW
following delicensing and return of the site to an agreed end state with the regulators and local
planning authority.
The ISF will be used to store operational ILW that has accumulated during the 60 years of plant
operation and can be adapted to store any additional ILW that is generated during
decommissioning of the plant after final shut down. The expected lifespan of the facility is 100
years.
As such the site selected for the construction of the EPR and the building design itself will
permit the expansion of the building for storing decommissioning wastes as they are generated.
The facilities will be designed to handle the different waste packaging geometries that will be
stored in the ISF.
The ILW will be stored in fully covered, concrete storage compartments that provide individual
storage volumes. The fully concrete storage compartments permit operator access, loading and
unloading, visual inspection and ventilation of the concrete storage compartments amongst
other functions.
The ISF will consist of areas performing the following functions:
· Receipt and dispatch area;
· Interim storage space for all operational ILW and possibly all decommissioning ILW
until a final disposal / solution facility becomes available (up to 100 years);
· Package Inspection area;
· A storage area that permits removal of ILW that may become LLW following a period of
decay storage.
