Over the past years, many Nuclear Power Plants (NPP) organizations have performed Probabilistic Safety Assessments (PSAs) to identify and understand key plant vulnerabilities. As part of enhancing the PSA quality, the Human Reliability Analysis (HRA) is key to a realistic evaluation of safety and of the potential weaknesses of a facility. Moreover, it has to be noted that HRA continues to be a large source of uncertainly in the PSAs. Within their current joint collaborative activities, Indizen, UPM and CSN are developing the so-called SIMulator of PROCedures (SIMPROC), a tool aiming to simulate events related with human actions and able to interact with a plant simulation model. The tool helps the analyst to quantify the importance of human actions in the final plant state. Among others, the main goal of SIMPROC is to check the Emergency Operating Procedures (EOPs) been used by the operating crew in order to lead the plant to a safe shutdown state. Currently SIMPROC is has been coupled with SCAIS software package [1], but the tool is flexible enough to be linked with other current plant simulation codes.

Results of SIMPROC application to the assessment of a LOCA accident in a PWR plant will be reported to illustrate the tool.
