New Safe Confinement, work on Chernobyl power plant foundation trench, 2010.
Since the disaster two major technical tasks have remained: The first is to make the destroyed unit 4 environmentally safe. The second is to safely and securely store the spent nuclear fuel from reactors 1-3, one of the most important stages in the decommissioning of these units.
Given that the original shelter was always only a makeshift solution, the stabilisation of the construction became a priority target. Accordingly, the first works carried out under the SIP were emergency repairs. The western wall was one of the structures that was most at risk from collapse, which could have caused the collapse of the roof.
Work to stabilise the roof and the western wall of the Chernobyl shelter began during 2004. It was completed in 2008. The dome shaped structure protected workers during the winter season.
During the stabilisation work strict radiation protection requirements for workers were adhered to. The site now includes a state-of-the-art change facility for 1,430 workers, with medical and radiation protection facilities and its own ambulance.
