This paper reports results of a qualitative analysis of procedure usage in NPP process control. The data was gathered in a test series that was conducted at the training simulator of the Fortum Loviisa nuclear power plant (NPP) in autumn 2008. The aim of the research is to construct understanding of the role of operating procedures in process control on a general level. In addition, the role of emergency operating procedures in structuring the activity in a specific accident scenario is studied. To demonstrate the methodology and to analyse in detail the role of procedures in one accident situation, the results concerning one run and one crew are presented.
