Information and Computer Systems in Automation:
Reliability of Energy Infrastructures


As the emerging smart electric grid and next generation nuclear power plants employ unprecedented levels of software, a multitude of new cyber-physical reliability challenges emerge from the interdependencies of software and physical components. Our group focuses on the specialized software platforms used in such applications as well as simulation and integration of simulators needed to identify risks in the cyber-physical system. We are engaged in interdisciplinary collaborations inside Aalto University and internationally to complement our background in software with electrical and mechanical reliability expertise.


We aim to use modern pedagogical methods to bring real-world relevance to teaching on the subject; for example, we run a safety-critical software development project against a simulator of a boiling water nuclear reactor’s refueling machine, in which the student teams are audited by a professional inspector.
