It took two weeks in … Major project milestones include: March 2004 An international tender for New Safe Confinement design and construction was announced. Ultimately, the final design was specified as consisting of three lines of two 4.50-by-1.00-metre (14.76 by 3.28 ft) foundation panels, each 21 metres (68.9 ft) in length, and a 4-metre (13.1 ft) high pile cap that reaches to a height of 118 metres (387 ft) of elevation.

The overall length of the structure is 150 metres (492.1 ft), consisting of 13 arches assembled 12.5 metres (41 ft) apart to form 12 bays. Chernobyl’s reactor No. This option was selected to minimize the cost of the foundation, the number of cuts into radioactive soil layers, dose uptake of workers, and risk to the environment from further contamination. David Haslewood suggested an arch, built off-site, and then slid over the existing Soviet-built sarcophagus because: Of the 394 entries, only the British submission proposed a sliding arch approach. Further upgrades to the area in preparation for New Safe Confinement construction were completed in 2010. September 1977. The New Safe Confinement (NSC) project is called to replace the original Soviet confinement constructed by November 1986, half-a-year after an ill-fated experiment at Chernobyl nuclear power plant on April 26, 1986, ended up with a thermal explosion of the active zone.The Chernobyl explosion became the biggest nuclear catastrophe of the 20th century. Balthasar Lindauer, EBRD Director, Nuclear Safety Department, said: “Despite an unprecedented level of international cooperation in the transformation of Chernobyl over the past decades, the decommissioning of the nuclear power plant and the management of radioactive waste in the exclusion zone remain the most challenging nuclear safety operations in the world. In order to provide an indestructible base for the New Safe Confinement, 396 enormous metal pipes are being hammered 25 meters deep into the ground. Rome2rio is a door-to-door travel information and booking engine, helping you get to and from any location in the world. [22][23] The storage is for both temporary high level waste as well as low and intermediate long-term level waste storage. Three types of carriages have been designed for the New Safe Confinement: The cranes' carriage interchangeability allows the rotation of the largest members to be demolished, reducing the overall size of the New Safe Confinement by approximately one arch bay.
