Energy Chernobyl Interactive Panoramas An up-close look at the continuing cleanup at Chernobyl. by Kevin Bullis June 21, 2011 Sponsored by This is the control room where workers monitored the tests that led to an explosion in reactor number four. Outside reactor building four, you can see the supporting structure erected to keep the sarcophagus encasing the ruins from collapsing. Opposite that is the construction site of an enormous arched structure that will be pulled over the top of the sarcophagus, encasing it and allowing it and the ruins inside to be dismantled for permanent storage. Concrete pads will serve as foundations for 19 towers that will be used to erect a new containment structure big enough to enclose the Statue of Liberty. A total of 396 25-meter long tubes will be driven into the ground to support the structure. Some 18,000 spent fuel assemblies are stored here—the metal plates conceal a deep pool that keeps the fuel assemblies cool.View a photo gallery of the nuclear cleanup of Chernobyl.
