The video discusses the damaged Chernobyl nuclear reactor, encased in a sarcophagus since the 1986 accident. Due to weathering, a new confinement structure is being built nearby, costing billions and lasting 100 years. This is a temporary solution, as uranium-238's half-life is 4.5 billion years, meaning it will persist long after Earth's life ends.
