A secret emergency plan has been drawn up as an underground blaze creeps towards a waste dump containing radioactive waste from the Manhattan Project, Daily Star reports.
The leaked document warns a “catastrophic event” will be triggered if the nuclear material is ignited.
A mushroom cloud of radioactive smoke could erupt over the densely-populated area of St Louis, in the US.
The fire is just 300 METRES from the dump. The underground blaze – at Bridgeton Landfill – has been allowed to smoulder for at least FIVE YEARS.
It has been creeping closer and closer to West Lake Landfill – next door – which was contaminated with radioactive waste from uranium processing illegally dumped in 1973.
The toxic pile includes material from the Manhattan Project – which created the first atomic bomb in the 1940s.
Fallout from the Chernobyl Nuclear Disaster, in Ukraine in 1986, reached as far as BRITAIN as winds carried the radioactive particles across the world.
But a recent report already found radioactive contamination in trees outside the landfill’s perimeter.
But the barriers are reportedly breaking down.
Missouri Attorney General Chris Koster warned Republic Services: “does not have this site under control.”
