The 2024 total is an increase of 66 TWh on the total achieved in 2023, with anadditional 40 TWh of generation in France making a significant contribution,as reactors continued to return to service after outages in 2022 and 2023. Construction started on nine reactors, six in China and one each in Pakistan,Egypt and Russia. Seven reactors were connected to the grid, four in China,and one each in France, India, UAE and USA. Four reactors shut down, twoin Canada and one each in Russia and Taiwan, China. Sama Bilbao y LeónDirector GeneralWorld Nuclear Association At the end of 2024, the 440 operable nuclear reactors worldwide had a totalcapacity of 398 GWe, up 6 GWe on 2023. This includes 19 GWe of capacityin Japan in suspended operation. The average capacity factor for the 410 reactors that generated electricityin 2024 was 83%, up from 82% in 2023. These high capacity factors areachieved by reactors of all ages, with no overall age-related decline incapacity factors observed. The case studies in this edition of the World Nuclear Performance Reporthighlight different aspects of nuclear reactor construction and operation.The first case study looks at how construction and operation of reactorsat Hongyanhe, in China, have been carried out to protect and support themarine wildlife in the region. The second case study looks to ways in whichthe future applications of the planned reactors at the UK’s Sizewell C couldbe diversified. With rising demand from new sectors, such as data servers and AI, thechallenge for the nuclear industry is to accelerate growth at the scale andspeed required to meet future needs. 1Nuclear industryperformance 1.1 Global highlights Nuclear reactors generated a total of 2667 TWh of electricity in 2024, up 66 TWh from 2601 TWh in 2023. This is thehighest ever generation from nuclear in one year, surpassing the previous record of 2660 TWh in 2006. Generation increased in Asia, with five of the seven reactors connected to the grid in 2024 being located in that region.Generation also increased in West & Central Europe, with the return to service of reactors in France following outages in2022 and 2023 contributing to this. In other regions, total generation in 2024 was broadly similar to the previous year. In 2024 the end-of-year capacity of operable nuclear power plants was 398 GWe,up 6 GWe on the 392 GWe at the end of 2023. This includes 19 GWe of capacityin Japan and less than 1 GWe capacity in India where the status is categorizedas 'Suspended Operation' by the International Atomic Energy Agency (IAEA). The total number of operable reactors at the end of 2024 was 440, up threefrom the previous year. The total capacity of reactors that produced electricity in 2024 was 369 GWe, up 1 GWe on the 2023 total. In additionto the 20 GWe of offline reactor capacity in Japan and India, a further 11 GWe of operable reactors did not produceelectricity in 2024. The six reactors at Zaporizhzhia in Ukraine comprise nearly 6 GWe of this. Figure 4 shows total global electricity generation from nuclear power plants by age in each year since 1970, withgeneration from reactors of different ages shown in distinct colours. The rapid expansion of nuclear capacity in the 1970s and 80s is reflected in the predominance of electricity generatedfrom young reactors. As the number of new reactors coming online fell in the 1990s and the reactors built in the 1970sand 1980s entered their second and third decades of operation, the proportion of electricity generated from olderreactors increased. Over the last decade, with the number of new reactors entering service each year gradually increasing, the amount ofelectricity generated by younger reactors has started to increase again. Most of the reactors
