<strong>atw</strong> Vol. 63 (<strong>2018</strong>) | Issue 5 ı May 336 Operating results 2017 – Part I* REPORT In 2017 the German nuclear power plants generated 84.63 billion kilowatt hours (kWh) of electricity gross. The Gundremmingen B nuclear power plant ceased operation on 31 December 2017 due to the revision of the German Atomic Energy Act in the political aftermath of the accidents in Fukushima, Japan, in 2011. Eight nuclear power plants with an electric gross output of 11,357 MWe were in operation on 31 December 2017. Three power plants in operation until 31 December 2017 achieved operating results with a gross production greater than 10 billion kilowatt hours and two power plants even produced more than 11 billion kilowatt hours. German nuclear power plants achieved two of the world’s ten best production results in 2017 (“Top Ten”). At the end of 2017, 449 reactor units were in operation in 31 countries worldwide and 56 were under construction in 16 countries. The share of nuclear power in world electricity production was around 11 %. German nuclear power plants have been occupying top spots in electricity production for decades thus providing an impressive demonstration of their efficiency, availability and reliability. The Shin Kori 3 nuclear power plant in the Republic Korea (capacity: 1,475 MWe gross) achieved the world record in electricity production in 2017 in its first year of commercial operation with 12,921,000 MWh. The German nuclear power plants Isar 2 (KKI 2, 11,523,513 MWh) and Emsland (KKE, 11,323,704 MWh) took the ninth and tenth place. * The reports with additional operating results of European nuclear power plants will be published in a further issue of <strong>atw</strong>.

The time availability factor is a degree for the deployability of a power plant. ** Energy availability factor kW = WV/WN: The energy availability factor kW is the quotient of available energy of a plant (WV ) and the nominal energy (WN). The nominal energy WN is the product of nominal capacity and reference period. This variable is used as a reference variable (100 % value) for availability considerations. The available energy WV is the energy which can be generated in the reference period due to the technical and operational condition of the plant. Energy availability factors in excess of 100 % are thus impossible, as opposed to energy utilisation. *** Inclusive of round up/down, rated power in 2017. **** The Gundremmingen nuclear power plant (KRB B) was permanently shutdown on 31 December 2017 due to the revision of the German Atomic Energy Act in 2011.
