Rolls-Royce Wins ‘Significant’ Contract For Loviisa Nuclear Station

UK engineering company Rolls-Royce has been awarded a “significant contract” by Finland utility Fortum to perform the partial renewal of the engineered safety features actuation system (Esfas) functions at Fortum’s Loviisa nuclear power station.

Esfas is a critical safety nuclear instrumentation & control (I&C) system which automatically manages safety features such as the isolation of main steam lines, main feedwater and emergency feedwater.

Rolls-Royce said it will partially replace the existing analogue systems with a digital system using its Spinline technology.

The installation will be carried out during planned outages in 2020 and 2021. The modernised system will be integrated into an existing long-term service agreement between Fortum and Rolls-Royce, which guarantees support to operate the I&C systems provided by Rolls-Royce until the end of the plant’s lifetime.

The renewed system will be designed, manufactured, tested, installed and commissioned by the Rolls-Royce I&C centre of excellence based in Grenoble, France, which has already provided I&C solutions to 150 nuclear power and research reactors.

The Loviisa nuclear station, operated by Fortum, has two 503-MW pressurised water reactors’ units. Unit 1 began commercial operation in May 1977 and Unit 2 in January 1981.
