Finnish nuclear regulator STUK has approved the overall architecture of the instrumentation and control (I&C) systems for Olkiluoto 3\u00a0but has asked for further studies to be completed before final approval.<\/strong><\/h4>\n

The Olkiluoto 3\u00a0EPR is being built for Finland\u2019s TVO by an Areva-Siemens consortium under a fixed-price \u20ac3\u00a0billion ($4\u00a0billion) turnkey contract. A press release by Areva said the company \u201cwelcomed\u201d STUK\u2019s approval as a \u201cnew, important step\u201d for the project and expressed its confidence in its I&C technology. However, statements by both STUK and TVO highlighted the additional evidence the regulator has requested.<\/p>\n

The additional information centres on the independence of the plant\u2019s digital I&C and backup systems: the regulator requires reassurance that the automated systems, which would ensure plant safety in the event of an emergency, do not rely on the same systems that are in use during normal operations.<\/p>\n

TVO\u2019s Olkiluoto 3\u00a0project director Jouni Silvennoinen said that testing of some I&C systems had commenced in parallel with STUK\u2019s review of the I&C architecture, but said that the plant supplier still needed to complete work on analyses of all possible I&C failure situations.<\/p>\n

Construction of Olkiluoto 3\u00a0began in 2005\u00a0but has faced many challenges resulting in several revisions to its estimated start-up date. TVO continues to say that it is not able to provide any estimate of the unit\u2019s likely start-up date at the current time, adding that the supplier consortium is responsible for the time schedule.<\/p>\n","protected":false},"excerpt":{"rendered":"
