It was pushed on Teflon pads by hydraulic pistons, and guided by lasers. The next video is starting stop. 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. Skip navigation. This feature is not available right now. Retrieved March 2, Special consideration was necessary for the excavation required for foundation construction due to the high level of radioactivity found in the upper layers of soil. Confinement de Tchernobyl : l'histoire - Duration: Retrieved February 9,

    One of the most ambitious projects in the history of engineering passes a major milestone today as the arch shielding radioactive waste caused by the Chernobyl nuclear power station accident has started sliding into place. Cologne, Germany. As a result of this, no assumptions about the load-bearing properties of the technogenic layer were made during the design of the foundation.

    Each of the steel tubes is made of high-strength steel to reduce cost and assembly weight.

    The exact methods for disposing of wastes generated by the demolition process have not been determined, and may include on-site burial outside the New Safe Confinement for low-level waste, and long-term storage inside the New Safe Confinement for medium and high-level wastes.

    The New Safe Confinement shows what is technically possible. Radioactive dust in the shelter is monitored by hundreds of sensors.

    It is expected that the primary contamination of most demolished elements will be loose surface dust and can easily be removed. Ultimately, the final design was specified as consisting of three lines of two 4.

    Fragmentation tools include plasma arc cutting torches, diamond circular cutting wheelsand diamond wire cutting. The study selected the sliding arch concept as the best solution for their further investigations and recommendations, primarily to reduce the chance of the construction workers receiving a harmful dose of radiation.

    These external panels are also used on the end walls of the structure.
