Paper Abstract:	Since operating procedures play an important role in nuclear process control by guiding and standardizing how to cope with demanding operational situations, it is important to have a clear understanding of how operating procedures are developed in the nuclear domain. We have investigated procedure development practices in two Finnish nuclear power plants. In this paper, we present a method for the analysis of these practices and some examples of the application of the method. We have interviewed procedure writers and other experts who are involved with procedure development work and explored the results using methodological tools of Practice and Activity Theory. Procedure development activity can be seen as a social practice, loosely supported by methodological guidance. Especially, the early phases of the development project seem to escape from generic characterization. Based on the interview data, some potential tensions and contradictions were identified, and they are discussed through the lens of Activity Theory.
