The Akademik Lomonosov floating nuclear power plant (NPP) in Russia’s Arctic Chukotka region has generated its first billion kilowatt hours, approaching five years since entering commercial operation. The floating nuclear power plant (FNPP), part of Rosatom’s Rosenergoatom division, provides about 60% of the energy for the western Chukotka region and Chersky in Yakutia and has been increasing its output each year. It began commercial operation in May 2020. It is the world’s only operating floating nuclear power plant. It is based, with its coastal infrastructure, on the city of Pevek – population 5000 – to which it supplies heat and power. The Akademik Lomonosov has two KLT-40S reactors generating 35 MWe each. It can provide electricity to a city with a population of up to 100,000 people.
