GIF ISAM (Integrated Safety Assessment Methodology) includes five analytical tools (i.e. QSR, PIRT, OPT, DPA, PSA) and it is intended that each tool be used to answer specific safety-related questions with different levels of detail during various design stages and the ISAM as a whole offers flexibility and a graded approach to analyse technical issues of complex system architectures. Although each tool can be selected for individual and exclusive use, the full value of the integrated methodology is derived from using all tools, in an iterative fashion and in combination with the others, throughout the design process. The paper describes what is ISAM and pilot examples of individual use of QSR, PIRT and OPT and also combination application of DPA-PSA.
