Requirements traceability experiences from SCORPIO core surveillance system

The purpose of the paper is to analyse the documentation produced during the development of SCORPIO-VVER core surveillance system for the Dukovany NPP in Czech Republic. The main idea was to search through the documents produced during the different life-cycle phases of the system development and try to analyse how requirements were transferred to design and further on to implementation and testing. The purpose was to examine the traceability of requirements and draw conclusions of the way how the project was carried out from the requirements engineering – especially requirements traceability – point of view
