Application of three-dimensional engineering models for engineering support of of decommissioning of NPPs

Early establishment of local information systems decommissioning allows to keep the knowledge of the power unit configuration for future generations of experts that carry out the practical work on the decommissioning. Completing the information databases should be a new way of fixing the results from the comprehensive engineering radiation surveys (CERS), carried out for the decommissioning of nuclear power units. Implementation of the comprehensive engineering and radiation survey should be formed taking into account the information, stored in local decommissioning databases. Information about CERS results must be entered in the database. The local database should be the basis of the information at all stages of the work for decommissioning of nuclear power plant: CERS, project development, practical work. It is necessary to provide access to the stored for all participants in decommissioning work.
