Fortum and Framatome have successfully modified the Preventive Protection System (PPS) at the Loviisa nuclear power plant. The Preventive Protection System uses control rods to monitor the reactor power and contributes to the safe operation of the plant and is part of the modernisation of the plant’s I&C system.
The project started in 2016 when Fortum awarded Framatome the contract to modify the PPS systems. The PPS systems are implemented in Framatome I&C platform, originally commissioned in 2008 (Unit 1) and 2009 (Unit 2).
Framatome’s I&C teams prepared the required documentation, designed and engineered the system modification and performed the final testing, installation and commissioning on site during the 2018 outage. These tasks are essential for the functionality of the entire system and are also mandatory for obtaining the licensing by the Finnish safety authority STUK.
"Both Fortum and Framatome have comprehensive knowledge of PPS systems and long term experience of working in Loviisa power plant. Together, we were able to build on the lessons learned and work done already in the previous LARA project. A joint team approach and close cooperation between Framatome and Fortum at all stages of the project were key to ensuring successful completion on time and to budget," says Site Manager Ulf Linden from Loviisa power plant.
