The facility is surrounded by a sand berm four miles (6.4 km) around and 160 feet (50 m) high, and contained the French-built research reactor Osirak, destroyed by Israel in 1981.
The neutrons released by nuclear fission are donated, producing Pu-239 and is the cheapest and easiest way to achieve large-scale production of plutonium.
The first was a highly orchestrated event requiring industrial machinery in which large pieces of shielding from the destroyed reactors was stolen.

Although the Iraqi government was able to smuggle some steel and carbon-fiber centrifuge units into the country, they needed at least a thousand to process industrial quantities.
