Operating results 2019In2019theseven(7)Germannuclearpowerplantsgenerated75.10billionkilowatthours(kWh)ofelectricitygross.Attheendof2019the Philippsburg 2 nuclear power plant ceased commercial operation duetotherevisionoftheGermanAtomicEnergyActinthepoliticalaftermath of the accidents in Fukushima, Japan, in 2011. Seven nuclear power plants with an electric gross output of 10,013 MWe wereinoperationduringtheyear2019.All seven nuclear power plants in operation in 2019 achieved
results with a gross production greater than 10 billion kilowatt hours, one power plant, The Isar 2 unit even produced more than 12 billion kilowatt hours.AdditionallytheIsar2unitachievedoneoftheworld’stenbest
production results in 2019 (“Top Ten”, sixth place). At the end of2019,449reactorunitswereinoperationin31countriesworldwideand 54 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 oftheirefficiency,availabilityandreliability.
TheTaishan-1nuclearpowerplant inChina(capacity:1,750MWegross, 1,660 MWe net, reactor type: EPR, the most powerful nuclear power plant worldwide and the most powerful single power plant worldwide) achieved the world record in electricity production in 2019withappr.13billionkilowatthours.
Worldwide, 41 nuclear power plant units achieved production resultsofmorethan10billionkilowatthoursnetintheyear2019.AdditionallyGermannuclearpowerplantsareleadingwiththeir
lifetime electricity production. The Brokdorf, Emsland, Grohnde, Isar 2 and Philipsburg 2 nuclear power plant have produced more than350billionkilowatthourssincetheirfirstcriticality.
* Availability factor (time availability factor) kt = tN/tV: The time availability factor kt is the quotient of available time of a plant (tV) and the reference period (tN). 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 2019.
**** 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.

Inthereviewyear2019,unitCofGundremmingen(KRBC)nuclearpower plant was operated at full load without any major restrictions except for one planned outage for refuelling.From 4 April to 21 April unit C was in stretch out operation.
During the shutdown a total of 152 fuel elements were unloaded and replaced with 112 fresh and 40 (2 MOX) partially spent fuel elements.
During the outage all safety relevant workings were monitored by the relevant nuclear controlling authority, the Bavarian State MinistryoftheEnvironmentandConsumerProtection(StMUV),andconsulted authorized experts. The inspection of the technical systems withregardtosafetyandreliabilityconfirmedtheexcellentconditionof the plant.Agrosstotalof10,381,798MWhofelectricitywasproduced.

General pointsDue to increased oil temperatures at the engine of the main coolant pumpJEB30AP001,aprecautionarybearingoilchangewascarriedout. For this purpose, theplantoutputwas reducedon10August2019from07:00hrstotheminimumloadpointof360MWwithagradient of 30 MW/min.Afterthescheduledcompletionoftheexchangeandstartofthe
main coolant pump, full load operation was reached again around 6:34 pm.
Aninternalemergencyexercisewasconductedon18November2019.The exercise started within the normal working hours. The scenario assumed was an earthquake close to the site, which caused the failure of the external main electricity supply and the cooling water supply of the emergency diesel generators as well as leakages in the storage pool cooling water pipe. In addition, the failure of various communication systems was assumed in the course of the exercise.
The emergency exercise was completed professionally and purposefully by a highly motivated team.

In 2019, the Neckarwestheim II nuclear power plant (GKN II) generated a gross output of 10,411,400 MWh. Net electrical generation was 9,758,339 MWh, of which 9,371,600 MWh weresuppliedtothepublicthree-phasegridand1,039,800MWhtothestatic converter system of Deutsche Bahn AG. The plant wasconnected to the grid for 7,699.8 hours. This results in a timeutilizationof87.90%.
Since the three-phase alternating current machine was commissioned,340,241,584MWhgrossand318,174,476MWhnethave been generated.

The completeness and effectiveness (conformity) of the process- oriented IMS, including the quality management measures, were confirmedbyappropriateinternalauditsaswellasbyaseveral-dayinspection by the assessor (ESN) and the supervisory authority at the GKN and KKP sites.
The modular and demand-oriented structure of the IMS according to KTA 1402 also enables continuous and efficient adaptation to thesite-specificrequirementsinoperation/post-operationinsubsequentyears. Another important focus will be the gradual integration of dismantling aspects into the IMS in order to exploit synergy effects.

Integrated management system (IMS) EnKK (NPP P, GKN, KWO)The integrated management system (IMS) of the EnBW Kernkraft GmbH (EnKK) with its partial system for nuclear safety (SMS), quality management (QMS/QSÜ) as well as environmental and energy management (UMS, EnMS, Umwelt- und Energie-managementsystem) were also in 2019 continuously further developed. Scope and content of each process descriptions were gradually adapted to the different internal requirements and related approval criteria. Besides the confirmation of conformity for theIMS, the recertification of the EnKK energy management system(EnMS, Energiemanagementsystem) according to DIN EN ISO 50001 took place in 2019 to improve energy efficiency. The certificate was thus exten ded by three years.
The completeness and effectiveness of the process-oriented IMS, including the quality management measures, were confirmed by appropriate internal audits as well as by a several-day inspection by the expert (ESN) and the supervisory authority at the GKN and KKP sites.
