equipment amounted to around 120ton of steel. The decommissioning project
included the dismantling of the equipment after decontamination, and the RAW
management.
Five storage tanks were used for liquid RAW before evaporation. The tanks were
made of structural steel with or without an inner layer of stainless steel. After sludge

removal, the tanks were decontaminated by high-pressure water jetting. A 63-m tank
was decontaminated, and after its integrity was checked and confirmed (Fig. 7.9)a
stainless steel liner was installed inside the tank (Fig. 7.10). This reuse saved the
resources that would have been required for the demolition of the old tank and the
fabrication and installation of a new one. The reuse also avoided radiation and indus-
trial safety issues that would have incurred during demolition of the component.

7.13 Barseb€ ack NPP, Sweden

The 615 MWe Barseb€ ack 1 BWR near Malm€ o, Sweden was shutdown in 1999 on
political grounds; unit 2 followed in 2005. During several years of social, economic,
and political discussions, much time and efforts were given to the plant’s post-
shutdown reuse. As quoted in International Atomic Energy Agency (2006) conflicting
views were put on the table. The local community preferred to use the plant’s space for
as a housing development, while local authorities were inclined to take advantage of
the existing infrastructure and use it for electricity production with a nonnuclear
source.
