Abstract:

Chernobyl Nuclear Power Plant, Ukraine -- Construction continues on the New Safe Confinement (NSC) dome intended to cover the sarcophagus entombing the remains of the No. 4 reactor at the Chernobyl Nuclear Power Plant destroyed by explosion in 1986. 

Following the April 1986 accident, then Soviet Union threw "liquidators" (soldiers, miners, and impressed workers) into hastily construction of the original sarcophagus. Built with great loss of life due to radiation exposure and subsequent illness, Soviet engineers soon calculated the original containment building would last only about 30 years and would require constant maintenance to mitigate leaks.
