Pernilla Allwin is a consultant from Risk Pilot AB. She works full-time in the Hanhikivi 1 project as a Human Factors Engineering (HFE) Specialist. Before joining Fennovoima, Pernilla was a member of the HFE team for the large modernisation project of Oskarshamn NPP in Sweden.

Human factors contributing to the safety of the Hanhikivi 1 nuclear power plant

Fennovoima's human factors engineering team ensures that the Hanhikivi 1 nuclear power plant is designed in such a way that it allows the future operating personnel to perform their work safely and effectively in all foreseeable operating conditions.

Around 80% of all incidents or accidents are either caused or significantly contributed to by human performance. Our task in Fennovoima’s human factors engineering (HFE) team is to ensure that we design the Hanhikivi 1 nuclear power plant in such a way that the plant can be operated successfully in every foreseeable operating condition, from normal day-to-day operation and outages to severe accident management. We approach the question systematically and consider the human role in delivering plant performance in all of those conditions over the whole operation phase and into decommissioning.

In practice, we are interested in the things that affect human performance. We apply scientifically based assumptions about how people are able to perform in their work and look at several factors behind that. For example, we look at staffing, training, competence within job roles, and the design of the organization. We also consider matters such as the impact of stress on human performance and the design's inclusiveness. After testing the assumptions, we implement it all in the design to ensure that the Hanhikivi 1 plant is designed in such a way that the operators, maintainers, and security staff can do their jobs reliably every day.

Adapting human factor engineering requirements to the practical conditions of the Hanhikivi 1 project has been challenging, but the situation is improving. Over the past couple of years, we have set the foundations of an effective and compliant human factors program that supports the plant's safety, availability, and compliance with regulations and requirements. We have developed clear expectations for both RAOS Project and Fennovoima to achieve the overall goal of human factors contributing to safety. We still have challenges integrating human factors across the design, both in the supplier scope and owner scope. However, we now have a solid technical foundation for the work.

The design decisions we make today fundamentally affect how safely and effectively the Hanhikivi 1 nuclear power plant can be operated by our workforce in the future.
