The training will start by recalling the basics on quality control, quality assurance and their evolution to Quality Management System and Integrated Management System. The requirements of international standards (ISO, IAEA…) will be discussed and compared in order to understand their respective approach, similarities and differences. Emphasis will be given on the process approach as recommended by IAEA in its recent publications and also on important issues like satisfaction of interested parties, graded approach, continuous improvement, transparency, communication to the public. A part of this training will be also devoted to introduce the importance concept of Safety Culture and provide examples of its integration in the Management System. Examples will be presented to show how the requirements from ISO 9001 and IAEA GS-R-3 are implemented in some Management Systems.
