nuclear power. the cost of extending plant lifetimes is competitive with other electricity generation technologies, including new solar and wind projects. In the United States, licenses of almost half of the operating nuclear reactors have been extended to 60 years. The U.S. NRC and the U.S. Department of Energy have initiated research into light water reactor sustainability which is hoped will lead to allowing extensions of reactor licenses beyond 60 years, provided that safety can be maintained, to increase energy security and preserve low-carbon generation sources. Research into nuclear reactors that can last 100 years, known as Centurion Reactors, is being conducted. As of 2020, a number of US nuclear power plants were cleared by Nuclear Regulatory Commission for operations up to 80 years. Post-Russian Invasion of Ukraine Following the Russian invasion of Ukraine on the 24th February, the situation has changed. With the Versailles Declaration agreed in March 2022, the EU leaders of the 27 member states agreed to phase out the EU’s dependence on Russian fossil fuels as soon as possible.The World Economic Forum has published energy policy changes, which were made because of the Russian Invasion. Korea is planning to "increase renewables in electricity [...] [and] nuclear power to over 30%". Japan has decided to "restart nuclear power plants aligned with the 6th Strategic Energy Plan [...]". Germany has decided to put off the shutdown of its three remaining nuclear power plants until April 2023. France, a country which welcomes nuclear power, is restarting all its nuclear plants. According to the EDF, France's biggest nuclear plant operator, 27 nuclear reactors must restart by the end of December, followed by 5 others between early January and mid-February 2023. These plans have since been changed, as a number of them wre closed down because of stress corrosion, which takes longer to repair References Nuclear power
