As Generation II reactors reach the end of their service life, some countries replace them with Generation III reactors or what is deemed "Generation III+ reactors". While Generation IV reactors include small modular reactors, the majority of "evolutionary" designs like the EPR have a higher capacity than comparable reactors of earlier generations. Furthermore, countries like Canada, which decided to refurbish its existing CANDU reactors, among them Bruce Nuclear Generating Station, the most powerful single site nuclear power plant outside Asia, have increased capacity at existing reactors by optimising efficiency. , Italy is the only country that has permanently closed all of its formerly functioning nuclear plants, with Germany phasing out the remaining 3 plants by the end of the year. Lithuania and Kazakhstan have shut down their only nuclear plants, but plan to build new ones to replace them, while Armenia shut down its only nuclear plant but subsequently restarted it. Austria never used its first nuclear plant that was completely built. Due to financial, political and technical reasons Cuba, Libya, North Korea and Poland never completed the construction of their first nuclear plants (although North Korea and Poland plan to). Azerbaijan, Bangladesh, Georgia, Ghana, Ireland, Kuwait, Oman, Peru, Venezuela have planned, but not constructed their first nuclear plants. Between 2005 and 2021 the global production of nuclear power increased by 1.1%. Overview A popular movement against nuclear power exists in the Western world, based on concerns about more nuclear accidents and concerns about nuclear waste. Anti-nuclear critics see nuclear power as a dangerous, expensive way to boil water to generate electricity. The 1979 Three Mile Island accident and the 1986 Chernobyl disaster played a key role in stopping new plant construction in many countries. Major anti-nuclear power groups include Friends of the Earth, Greenpeace, Institute for Energy and Environmental Research, Nuclear Information and Resource Service, and Sortir du nucléaire (France). Several countries, especially European countries, have abandoned the construction of new of nuclear power plants. Austria (1978), Sweden (1980) and Italy (1987) voted in referendums to oppose or phase out nuclear power, while opposition in Ireland prevented a nuclear program there. Countries that have no nuclear plants and have restricted new plant constructions comprise Australia, Austria, Denmark, Greece, Italy, Ireland, Norway and Serbia. Poland stopped the construction of a plant. Belgium, Germany, Spain, and Sweden decided not to build new plants or intend to phase out nuclear power, although
