The Personal Organisation in German NPP is described in the Operational

Manual.

The Organigram is split into a part with licensed personnel and a part with

non-licensed personnel.

The Outage Office Team is gradually being built up during the planning phase

ca. 3 months before begin of outage.

These licencees organise different works together with the system engineers

and prepare the safety measures � Few interfaces!
