The Working Group on Operating Experience (WGOE) has observed that events with heavy loads are a contemporary issue to address after several operating experiences in recent years. The WGOE made a proposal to analyse events as well as to determine the regulatory approach to licensee management of the lifting of heavy loads in nuclear power plants within NEA countries. Specifically:

  • To collect and review operating experience from events involving the lifting of heavy loads.
  • To compare regulatory requirements for nuclear lifting systems.
  • To identify lessons learnt for sharing knowledge among regulatory bodies (RB).

To achieve a good result and be able to analyse the subject, each member country was asked to respond to a questionnaire (see Annex 1) and to search their national databases. Eleven countries responded to the questionnaire and 114 events from 16 countries have been analysed.
