Services for Operating Nuclear Power Plants

As a licensee and operator of Loviisa nuclear power plant and waste management facil­ities, we have more than 40 years of experi­ence in mainte­nance and opera­tions. Operators all over the world encounter different kinds of technical and licensing related challenges, which eventually have impact on power production. Before starting a costly project to streamline the mainte­nance and operation of a nuclear power plant, it is worth to discuss with us about our experi­ences related to the imple­men­tation of refur­bishment projects.

Optimisation of maintenance is of the essence to increase the performance of a nuclear power plant. Sometimes annual outages include also upgrades and modernisations to increase the nuclear safety and production of the plant. A refurbishment project usually takes a lot of time and, depending on the size of the project, includes various phases. It starts with extensive planning activities including licensing plan and communication with the local nuclear safety authority. Fortum’s experience in driving complex renewal projects consist of several areas and disciplines, such as equipment reliability (ER) management, I&C modernisation, lifetime extension etc. Fortum’s knowhow about nuclear technology and plant performance update serves best when applied at an early stage of the project.
