Neckarwestheim. Unit II of the Neckarwestheim nuclear power plant (GKN II) was finally disconnected from the electricity grid at around 11:59 pm last night (15 April 2023). EnBW has thus complied with the requirements under the Atomic Energy Act within the specified time limit. The shutdown process proceeded technically according to plan and without incident. In the coming weeks, EnBW will begin the initial preparatory work for dismantling the unit. The necessary licence has already been issued.
GKN II is a pressurized water reactor with an electrical output of 1,400 megawatts (MW). It fed electricity into the public grid for the first time on 3 January 1989. At around 11 billion kilowatt-hours per year, the unit has generated a total of over 375 billion kilowatt-hours of electricity in its 34 years of operation. GKN II met about one-sixth of total electricity demand and about two-thirds of private household electricity demand in the state of Baden-Württemberg.
The final shutdown of GKN II was a standard technical process comparable to previous shutdowns prior to annual inspections. During shutdown, the reactor power level was continuously reduced by gradually inserting what are known as control rods into the reactor core. After lowering the reactor power level in this way, the unit was disconnected from the public electricity grid at around 11:59 pm.
