Decommissioning & Dismantling

The careful and meticulous dismantling of our plants is an aspect that is very close to our hearts. Demolition of the nuclear power plants at Stade (Lower Saxony) and Würgassen (North-Rhine Westphalia) is well advanced. These two projects have provided us with comprehensive experience in dismantling power reactors and we have demonstrated that we are able to demolish nuclear power plants in a safe and environmentally compatible way. We use tried and tested techniques, standard commercial methods and drive innovation. Because we take responsibility: here and now!

 

Dismantling of Isar 1

PreussenElektra intends to dismantle KKI 1 using the direct method. With this method, it is assumed that some of the irradiated fuel elements will still be present in the plant when the demolition work commences.

It is currently planned to dismantle the plant in two phases, for which separate permits have been requested under the Atomic Energy Act. Once these permits have been issued, it will be possible to carry out the work packages for the two phases in parallel, so long as they do not interfere with each other and are in keeping with the protective aims, as well as radiation protection, health & safety and fire protection requirements.

Dismantling of Stade

First commercially operated Pressurized Water Reactor in Germany to be dismantled.

The Stade nuclear power plant was Germany's very first purely commercial nuclear power plant to use a Pressurized Water Reactor (PWR). Its output was about half that of subsequent plants. Nevertheless, when it was commissioned it was the most productive PWR plant in Federal Germany. In autumn 2000, the decision was taken to decommission the plant for economic reasons, starting in the autumn of 2003. Once the licence had been obtained, dismantling work started in September 2005. 

Dismantling of Unterweser

PreussenElektra intends to dismantle Unterweser using the direct method. With this method, it is assumed that some of the irradiated fuel elements will still be present in the plant when the demolition work commences.

It is currently planned to dismantle the plant in two phases, for which separate permits have been requested under the Atomic Energy Act. Once these permits have been issued, it will be possible to carry out the work packages for the two phases in parallel, so long as they do not interfere with each other and are in keeping with the protective aims, as well as radiation protection, health & safety and fire protection requirements.

Dismantling of Würgassen

Dismantling of the nuclear section successfully completed!

The Würgassen nuclear power plant is the first commercially operated power plant in Germany to be released from the control of nuclear legislation. In 1995, after 23 years of electricity production, the then PreussenElektra AG decided to decommission Würgassen NPP on economic grounds. The dismantling work was completed on schedule on 29 August 2014, once all the control measurements had been performed. The very last operating system, the back-up ventilation system, had only just been decommissioned the day before. This marked the completion of all dismantling and decontamination work in the control and monitoring area.

"17 years of dismantling work have given rise to plenty of challenges, which we have always overcome with a fair amount of creativity and great determination. Our experience has already proved useful for our second dismantling project, Stade, and will serve us well in our upcoming dismantling projects," says plant manager Markus Wentzke. 

Dismantling of Grafenrheinfeld
