Decommissioning and dismantlement of the Stade nuclear power ...

Dismantlement Phase I

1 Materials air lock and air recirculation unit
2 Flood tanks
During the first dismantlement phase the necessary
logistics systems are established within the radiation
control area and as many non-required nuclear
systems as possible are removed to create more
space for subsequent dismantling work. The dismantlement
of the larger plant components is also
planned at this time.
The diagram above shows some of the systems
that are dismantled and removed during
Dismantlement Phase I:

3 Control rod assembly
4 Pressurized water tanks
_ The flood tanks that feed the primary loop
during start-up and shut-down.
Dismantling these helps to create extra space
for the treatment and interim storage of waste
materials from the dismantlement process.
_ The control rod assembly.
The individual components making up this
assembly are also small and their dismantlement,
which frees up space in the reactor chamber,
is uncomplicated.
_ The pressurized emergency cooling tanks and
other nuclear-contaminated systems that are no
longer required for the subsequent dismantlement
work.
However, some non-nuclear plant components
such as the live-steam and feedwater systems,
the emergency diesel generator set, and turbine
and generator components are also disassembled
and removed during this period.
