A re-creation of the experiment involved in the 1945 incident. The sphere of plutonium is surrounded by tungsten carbide blocks acting as neutron reflectors.. The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb.
A major accident might result in loss of life and severe health effects, and Groves was concerned that even a minor one could disrupt vital war production – particularly of aluminum – or require evacuation of the Manhattan Project's isotope separation plants. But spreading the Oak Ridge facilities over a larger area would involve the ...
During an experiment on August 21, 1945, Daghlian was attempting to build a neutron reflector manually by stacking a set of 4.4-kilogram (9.7 lb) tungsten carbide bricks in an incremental fashion around a plutonium core. The purpose of the neutron reflector was to reduce the mass required for the plutonium core to attain criticality.
As part of the Manhattan Project, Hanford produced the plutonium to build Fat Man, the atomic weapon that was detonated above Nagasaki at the end of World War II, and for the United States ...
