5. International experience of decision-making on decommissioning strategy
Germany has the most extensive and successful experience of NPP decommissioning planning and implementation in the world. That experience is the closure of 5 VVER-440 power units at NPP Nord near the town of Greifswald on the Baltic Sea coast. There the decision on the reactor decommissioning, which followed the «BROWN FIELD» scenario, was taken due to the socio-political situation of the day and technical state of the nuclear plant.
Following a strategy since the early 1990s, the social infrastructure of the nuclear neighborhood was transformed without serious social disruption. Problems related to the loss of thousands jobs were resolved. It became possible due to the social partnership of authorities, business and public. This experience is presented in detail in appendixes 1, 2 and in the video attachment to this document.
A large techno park has been established on the former NPP site using its buildings and
structures. The techno park provides conditions for entrepreneurship and different kinds of economic activities. It hosts hi-tech companies oriented toward the dismantling and recycling of contaminated equipment, operation of long-term RW and SNF storage facilities and radiation safety provisions.
New facilities and companies include biofuel production, pontoon manufacturing, a sea terminal in the NPP discharge channel, etc.
The German experience has shown that:
- contaminated equipment can be dismantled without waiting for 50-70 years necessary for the short-lived radionuclides decay; at this the dose rate for the personnel employed in dismantling was lower than during the plant operation;
- in the decommissioning of power units, which reached the design time limit, it is expedient to use the existing NPP infrastructure - this helps to cut the cost of dismantling, create new work places, reduce the unemployment problem.
In this topic, the stages and possible scenarios of decommissioning nuclear power plants are examined.
