A group of 400 miners descended deep below reactor 4. The miner’s task was to fill the space below with more concrete so the reactor wouldn’t burn through. Without the stabilizing concrete, radioactive material would reach the Black Sea, contaminating the drinking water of millions. Although the Black Sea was never effected, no more risks could be taken.  As of November 29, 2016, 30 years and 7 months later after the initial explosion, the final steel sarcophagus was laid where it sits to this day. The final sarcophagus sits atop the original concrete “sarcophagus”. The need for a new sarcophagus appeared as the original was deteriorating, letting radiation leak. The new sarcophagus predicts to last another century. In total, over 600,000 liquidators were part of the Chernoby process, but the process still isn’t finished. Once technology further advances, the radioactive material under the sarcophagus will be disposed of.  Extensive protocols were enforced after “the worst nuclear accident in history”, an accident of Chernobyl’s nature will never happen again. ​​​​​​​
