Chernobyl Confinement Shelter
Tony Gee was appointed to carry out the independent check of the temporary towers and foundations for the strand jack installation as well as the stage by stage analysis and check of the steel arch and piled foundations. This included seismic design and a response spectrum analysis in accordance to Eurocodes, as well as consideration of Russian and Ukrainian Standards. The scheme comprises the design and construction of an arch-shaped confinement shelter; an 18,000-metric ton metal structure.
The arch was assembled to the west of the damaged reactor (unit 4) and will be slid into place above the existing sarcophagus. Its prime aim is to contain the radioactive material, protect against weather damage to the existing sarcophagus built just after the accident in 1986, and to allow work to progress on the deconstruction of Unit 4.
