But the situation at the nuclear power plant remains very serious and new strategies are considered to stop nuclear fire and radiation. According to a CNN report first tests are now planned to pump concrete into the plant's No. 4 reactor spent nuclear fuel pool and containment vessel. This means high performance concrete pumps, a sophisticated delivery line system, non-ballasted stationary booms and demanding concrete mixtures. Putzmeister, the German manufacturer of concrete pumps, and the largest in its field, is now at Fukushima to help. The company has experience from the Chernobyl disaster and is the world record holder pumping concrete to a height of more than 700 m at Burj Khalifa Tower, currently the tallest man-made structure ever built.
