the results. For example, in a previous study , the “What If” analysis was chosen due to the relative immaturity of the reactor design being analyzed at the time of the study. However, in the present work, the two methodologies selected are the Hazards and Operability (HAZOP) study and the Failure Modes and Effects Analysis (FMEA).
