Training and retraining based on knowledge management is necessary to ensure that NPP personnel remain highly qualified to do their tasks. Programmes for initial and upgrades in training, including the use of simulators should be in place. These should also include the following aspects: Training in safety culture, particularly for management staff, the adoption of a questioning attitude, etc.

Many NPPs will be entering their new licensing period, which may be regarded as being beyond the nominal design life, but not their technical life, thanks to PLiM measures. In particular, these highly experienced personnel not only possess detailed knowledge concerning the particular SSC they were responsible for, but also have a good general appreciation for the characteristic behaviour of the NPP as a whole. A factor in a NPP’s PLiM strategy must therefore be to ensure that sufficient replacement personnel are available and that the transfer of knowledge is guaranteed via adequate on-the-spot training and comprehensive documentation.
