Thirty years after the nuclear disaster Greenpeace revisits the site and the Unit 4 with the New Safe Confinement (NSC or New Shelter).

The new giant structure is intended to contain the nuclear reactor. Its primary goal is to prevent the reactor complex from leaking radioactive material into the environment and the secondary goal is to allow a future partial demolition of the old structure.
The NSC is designed to contain the radioactive remains of Chernobyl Unit 4 for the next 100 years while giving scientists the time to create technologies to deal with the melted core of the reactor.
