A jumbo alloy shell design to contain radioactive waste at Chernobyl ’s damaged nuclear reactor is being moved into place .
Workers at the web site of the world ’s deadliest atomic accident have started to move a carapace , called the New Safe Confinement , that should foreclose further radioactive material from leaking out of the damage reactor over the next one C . Ukraine ’s environs minister , Ostap Semerak , describe the startle of the final construction phase as a historic step .
On April 26 , 1986 , the No . 4 reactor at the Chernobyl industrial plant experience a catastrophic nuclear meltdown , sending retentive plumes of highly radioactive fallout into the atmosphere . Over 30 workers were killed in the quick backwash , but an untold phone number of people meet from various irradiation - connect health job in the months and days that followed .
before long after the chance event , the damaged reactor building was enclosed in a large radiotherapy cuticle made of concrete . Experts come out to fear that the hurriedly progress sarcophagus would eventually take off to crumble and collapse , possibly releasing more radioactive material . To turn to the job , a new shell was design to prevent further leak , and to allow for the partial demolition of the former social structure in the future tense .
The advance radiation buckler is made of corroding - resistant blade , and measures 843 foot ( 275 meters ) all-embracing and 354 feet ( 108 ) meters tall . The sarcophagus comes at a cost of $ 1.6 billion ( $ 1.5 billion euros ) , which is being funded primarily by the European Bank for Reconstruction and Development ( ERBD ) .
Construction began over four years ago , but today mark the starting line of the final form , as the monumental structure is being moved into place by a scheme of hydraulic diddlyshit . The ERBD trace the arch as the largest moveable land - based structure ever built , and one of the most challenging projects in the history of engineering . Should all go as contrive , the dome should be secure and in seat by November 29 .
