Rolls-Royce wins contract to upgrade Loviisa I&C system

22 April 2020

Rolls-Royce has been awarded a significant contract by Finnish power company Fortum to perform the partial renewal of the Engineered Safety Features Actuation System (ESFAS) functions of the Loviisa nuclear power plant in Finland.

The ESFAS is a critical safety nuclear instrumentation and control system. The ESFAS 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 onsite installation will be carried out within planned outages in 2020 and 2021, without any impact on their duration," said Stephane Lessi, Business Unit Director, Rolls-Royce Civil Nuclear France.

In addition, the modernised system will be integrated into an existing Long Term Service Agreement between Fortum and Rolls-Royce. This agreement "guarantees the necessary support to operate the I&C systems provided by Rolls-Royce until the end of the plant's lifetime,' Lessi added.

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

In March 2019, Rolls-Royce completed a two-year I&C modernisation at Loviisa nuclear power plant.
