Computer-based emergency operating procedures offer some benefits compared with the paper-based EOP. However, most of them do not fully provide clear and necessary information related to the procedure steps, such as future plant behavior and the affected components after taking an action of each step because of the limited space available on the virtual display unit. This paper investigates a technique to derive and indicate such kind of information using a Multilevel Flow Modeling model of simplified EOP of steam generator tube rupture accident of a pressurized water reactor plant. In this case, the MFM model is built based on operator’s action on each procedure step. Then, by using the influence propagation rules for function primitives of MFM model, the influenced functions of plant components necessary for confirming the procedure step can be gathered. This information will help operators to understand and take the actions in order to achieve the objective of each procedure step.
