Nuclear power plants are licensed by the NRC for 40 years. It contains information on operating experience of worldwide nuclear power plants. Britain’s old nuclear power stations supply about a fifth of electricity supplies and are a key part of the energy system. Total nuclear capacity declines by 20% by 2030 in the EU, with the largest reductions in Germany, Belgium, Spain and France. The capacity factor for renewable resources such as a utility-scale wind or solar facility is significantly less than a baseload nuclear, coal or natural gas plant due to the variability of the wind and sun. Except for the reactor, a nuclear power plant is similar to a large coal-fired power plant, with pumps, valves, steam generators, turbines, electric generators, condensers, and associated equipment. This post looks into the reasons for this large difference and also … "However, there is an increasing trend in some countries for nuclear reactors to operate in a load-following mode, which will reduce the overall capacity factor." The capacity factor for the global fleet stood at 82.5% in 2019, up from 79.8% in 2018. The capacity factor of a conventional nuclear or coal fired power plant is under management control and may be over 80%, whereas the capacity factor of wind generators or solar power plants depends on the elements and is typically less than 40% with 25% not being unusual.
