Nuklearer Notfall in Japan

Nuklearkrise verhindert

Am 11. März 2011 wurde Japan von einem schweren Erdbeben und einem Tsunami heimgesucht, die das Kernkraftwerk Fukushima Daiichi schwer beschädigten. Die Kühlsysteme mehrerer Reaktoren fielen aus, was zu einem Temperaturanstieg und der Gefahr der Exposition von Brennstäben führte. Die Situation eskalierte zur schwersten nuklearen Notstandskrise seit Tschernobyl.

Cooling water used to reduce radiation

In response, the Tokyo Fire Department launched a nuclear emergency operation to cool the No. 3 reactor, which contained highly toxic fuel. Firefighters used a high-tech unmanned fire truck to spray seawater from a height of 22 meters onto the reactor’s spent fuel pool, reducing direct radiation exposure to personnel.

Continuous waterflow of 3000 liter per minute

The fire truck was powered by a Hytrans mobile water system, which continuously pumped large volumes of seawater. The system supplied water at a rate of 3000 liters per minute over a seven-hour period, delivering a total of more than 1,260 tons of water. Thanks to the high capacity and flexibility of the Hytrans submersible pump and hose system, critical cooling was achieved, and explosions were prevented during a time when conventional infrastructure had been destroyed.

The Hytrans units were delivered to the Tokyo Fire Department several years earlier and proved to be of vital importance in this nuclear emergency situation.

Hytrans-Systeme werden vor Ort eingesetzt

• 1 HydroSub 150 zum Pumpen von Kühlwasser aus dem Meer in den Reaktor und 1 HydroSub 150 als Notstromaggregat.
• Mehrere Kilometer 6″-Schläuche
