Designing of automation is proceeding in the Olkiluoto 3 project


The Finnish Radiation and Nuclear Safety Authority (STUK) has reviewed the plans submitted by Teollisuuden Voima Oyj (TVO) concerning the functional entity comprised of the automation systems of the Olkiluoto 3 nuclear power plant unit. According to STUK's understanding, no notable change needs are foreseeable for the design of  Olkiluoto 3 automation.

STUK states that considerable progress has been made in the design of automation. However, STUK has requested TVO to update the reviewed documentation in such a manner that it provides the necessary initial information for detailed system design in an unambiguous format. In particular, STUK requires that the principles of securing the mutual independence of systems backing up each other are defined clearly enough.
