Nuclear power

Nuclear power in general

Nuclear power produces reliable and CO2-free supply of electricity at a competitive and predictable price.
As a carbon dioxide free form of electricity nuclear power has an important role to play in mitigating climate change. Nuclear power life cycle greenhouse gas emissions are as low as wind, hydro and solar power.
In 2014, nuclear power accounted for approximately 16% of electricity production globally. Nuclear power accounts for about one third of the electricity production in Europe. Also in Finland one third of electricity production is nuclear power. While no new nuclear power plants have been taken into use for decades, has nuclear production increased due to power upgrades of the existing power plant units.

The majority of the world's nuclear power plant reactors are light water reactors that use ordinary water as the neutron moderator and as the fuel coolant. There are two basic types of light water reactors: boiling water reactors and pressurised water reactors. Of the world's nuclear reactors used for electricity production, about 66% are pressurised water reactors and about 23% boiling water reactors.
power plant (CHP). This would increase the plant's energy efficiency by several tens of percents.
