As can be seen from the figure, the PMIS at EWN is of the stand-alone type and was tailored to the
specific needs of the decommissioning process. Issues such as 'Work package approval', covering the
internal approval process, and 'Mass flow/Disposal' are two aspects that play a specific role in
decommissioning projects and would not be found in a traditional or conventional construction
project. Another aspect included in EWN’s PMIS is personnel development, relevant for
decommissioning, which is not necessarily included in a standard PMIS for a construction project.
To demonstrate the complexity of such a decommissioning project the EWN project structure
hierarchy is shown in Figure 23. Included are the six sub-projects:
Deconstruction of the nuclear power plants at Rheinsberg (KKR) and Greifswald (KGR);
Refurbishment of tools necessary for decommissioning;
Operation of the interim waste storage facility Zwischenlager Nord (ZLN);
Waste management (e.g. waste treatment, release from regulatory control, etc.), and
Site remediation and re-use.

The hierarchy of the complete projects split into 24 part projects, those into 81 programmes, etc., and
reaches down into 7 312 single tasks. Some of those, on all different levels, are interrelated, some are
independent. Each step requires specific resources, competences, etc.. To keep an overview and to
