France’s Framatome has been awarded a contract for modernisation of reactor protection system (RPS) at Switzerland’s Goesgen nuclear power plant, operated by the Swiss utility Kernkraftwerk Gösgen-Däniken (KKG).  

“This contract marks another important milestone in the long-lasting cooperation between Gösgen NPP and Framatome,” said Frédéric Lelièvre, Framatome’s senior executive vice president in charge of Sales, Regional Platforms and the Instrumentation and Control Business Unit. “It is yet another example showing how, over the years, we have managed the transformation from analog to digital technology successfully together.”

The scope of the contract includes modernisation of the entire RPS using Framatome‘s proven digital instrumentation and control (I&C) platform, TELEPERM XS. In addition, important functions will be realised with a diverse hardwired back-up system. Installation and commissioning of the new RPS are scheduled for the plant’s 2022 outage. Framatome said the modernisation project enhances plant safety, supports long-term operation and protects investments into the future.

The signing of the contract was preceded by the successful modernisation of the plant’s four emergency diesel generators, including the upgrade of the entire I&C and electrical systems with Framatome’s digital technology.
In 2014, Framatome completed the digital modernisation of the plant’s reactor control and limitation.  

Goesgen, a 1010MWe pressurised water reactor was connected to the grid in 1979. KKG operates the plant on behalf of its five owners: Alpiq AG (40%), Axpo Power AG (25%), the City of Zurich (15%), Centralschweizerische Kraftwerke AG (12.5%) and the Energie Wasser Bern (7.5%). The plant generates about 13% of Switzerland's electricity.
