Reliable, predictable and CO2-free power generation
The Finnish Government has granted a new operating licence for Fortum’s Loviisa nuclear power plant until 2050Nuclear
Nuclear power plays an important role in clean energy production. As a reliable, CO2-free energy source, it helps satisfy today’s electricity needs and improve security of supply while mitigating climate change. Over its lifecycle, nuclear power has a carbon footprint as low as wind, hydro and solar power.
CO2-free for climate
Nuclear power generates electricity without releasing harmful emissions into the air and helps to achieve carbon neutrality targets.
Stable and reliable
Our nuclear power plants provide a steady and reliable supply of electricity to the society. It improves energy self-sufficiency and security of supply.
Proven safety
Multiple isolation, redundancy and extensive training ensure that nuclear power is safe.
Clean energy
Climate change and the transition to a low-carbon energy system means that reliable, emission-free power generation is more important than ever. As a CO2-free energy production method, nuclear power is a key part of our strategy for a clean-energy future and supports achieving Finland’s and Europe’s carbon neutrality targets.
Always on
A steady source of electricity is critical during periods of increased energy consumption. And unlike other CO2-free production methods, we can count on nuclear power because electricity is generated at a consistent rate regardless of weather conditions. Nuclear helps to improve energy self-sufficiency and security of supply.
40 years of safety
Extensive employee training with our plant operation simulator continues to strengthen our safety-oriented work culture and large annual investments in plant modifications ensure that all aspects of daily operation are considered as we continuously improve safety.

FAQ - Nuclear power
What is nuclear power?
Nuclear power production is based on the utilisation of the thermal energy generated by a controlled chain reaction. A nuclear power plant works much like a conventional power plant, but instead of burning e.g. coal, natural gas or peat, a nuclear power plant uses uranium as a source of energy.
How does nuclear power work?
A nuclear power plant uses heat from a nuclear reaction to create high pressure steam which is put through a turbine to generate electricity. Light water reactors, such as the pressure water reactors at Loviisa nuclear power plant, use enriched uranium as fuel.
What is nuclear energy used for?
It is mainly used to produce electricity, but heat generated by the nuclear reaction can also be used to provide heating for homes in a residential area (district heating).
Is nuclear power safe?
Nuclear safety is based on multiple isolation and parallel safety measures. Systematic maintenance and modernisation as well as training of personnel guarantee operation in line with current standards and strengthen safety-culture.
Light water reactors, such as the pressure water reactors at our Loviisa NPP, are simple in their basic characteristics and inherently stable. Their natural safety characteristics, which are based on physical feedback loops that moderate the increase of power output, together with the basic design of the reactors make the uncontrollable increase of reactor power output impossible. Light water reactors are very suitable for energy production, and they have proven safe and reliable, which explains their popularity. For these reasons, the further development and construction of new nuclear power plants has mainly focused on light water reactor technology.
