A criticality accident occurred on December 30, 1958, at Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, in the United States It is one of 60 known criticality events that have occurred globally outside the controlled conditions of a nuclear reactor or test; though it was the third such event that took place in 1958 after events on June 16 [1] at the Y-12 Plant in Oak Ridge ...
The two criticality accidents occurred at the Los Alamos Laboratory in New Mexico on August 21, 1945, and May 21, 1946. In both cases, an experiment was intended to demonstrate how close the core was to criticality with a tamper (layer of dense material surrounding the fissile material). Still, the core was accidentally put into a critical ...

These changes did not prevent another criticality accident from happening at Los Alamos the following year. Louis Slotin, a colleague of Daghlian's, was killed in 1946 while performing criticality tests on the same plutonium core. [6]
