Within the scope
of the preliminary planning, Babcock Noell Nuclear worked out a conception for the
dismantling of the reactor pressure vessel and closure, its internals and of the
biological shield, based on a dry dismantling procedure.
Particular attention was paid to a time schedule-related and logistic decoupling of the reactor pressure vessel dismantling from the other dismantling measures. Dry dismantling of the reactor pressure vessel in the reactor well was planned in order to dismantle the equipment for provision and sewage of water independant from the work on the reactor pressure vessel. Besides optimal shielding by the existing building structure situation, design of the devices and equipment for underwater operation is not necessary.
In total, this conception is also characterized by high flexibility and a favourable price.
