Panic at massive nuclear plant as airspace locked down
An emergency was declared at a massive nuclear complex in the US after a fire broke out at a laboratory handling radioactive materials, triggering restrictions on air and rail traffic and incoming vehicles. The fire prompted an emergency declaration at Savannah River National Laboratory in South Carolina , a vast facility where the US government once produced materials used in nuclear weapons, including tritium and plutonium-239. Incoming traffic was shut down, while air and rail services in the surrounding area were restricted as emergency measures were put in place.

TL;DR
- An emergency was declared at the Savannah River National Laboratory in South Carolina.
- A fire broke out in a laboratory handling radioactive materials.
- Air and rail traffic were restricted in the surrounding area.
- Incoming traffic to the facility was shut down.
- The laboratory previously produced materials for nuclear weapons, including tritium and plutonium-239.
