Background and objective

Participative development with human factors focused frameworks and models is known to add value for safety management. Technologically driven and proceduralized nuclear industry still lacks full utilization of this option to improve overall system capacity, safety and competence.

Participative development for supporting human factors of safety (PARSA) project speeds up learning and verbalizes tacit knowledge through participatory research and practices in nuclear industry. PARSA models nuclear maintenance work and facilitates learning and communication between organizational levels as well as among nuclear actors by conducting case studies at two NPPs.  The project uses video-based reflection and collaborative work process analysis as methods, and conducts a critical inquiry to nuclear specific human performance tools, with applicative targets.

Results exploitation and effect on safety

We aim to improve new ways of action, guidance, operational practices and practical solutions that promote nuclear safety competence and organizational learning, by modelling tacit knowledge, mastery of work processes and human focused work practices in nuclear maintenance operations. The end users are regulators, NPPs, researchers, practitioners and students at nuclear domain, as well as at other safety critical fields. The first findings will be available at the end of 2019, and the final results in 2022.

News on Project

llkka Asikainen, Parsa-project team member
We have started the PARSA project with preliminary interviews of the workers, experts and management of Finnish nuclear power plants. We have gained a good understanding of what the actors consider development priorities in nuclear maintenance work. This helps us focus the project to topics that are considered relevant in the plants. Next, we will continue prioritizing the research topics in the joint workshops with nuclear actors, and preparing to move on to the next phase of the project – holistic modeling of nuclear maintenance work. We are also planning the following year’s events with Finnish plants and other nuclear actors.
