Keep an eye on the shift supervisor.
"It was noticed that the solution was a combination of organic and aqueous solution [gunk in the tank.] Two operators [instructed by the shift supervisor] used an improvised setup to decant the dark brown [concentrated plutonium] organic solution. The shift supervisor then left to tend to other duties. During the second filling of the bottle, a mixture of aqueous and organic solution was drawn in. As a result, the operators stopped filling the bottle."
One asked the shift supervisor for further instructions. He was told to continue decanting the solution. This operator "poured it into the 60 L vessel for a second time. After [most] of the solution had been poured out, the operator saw a flash of light, and felt a pulse of heat. Startled, the operator dropped the bottle, ran down the stairs, and from the room."
The plutonium was too concentrated, and he had accidentally started a nuclear chain reaction! The alarms sounded, and everyone evacuated. So far, no fatal errors. But a second criticality happens while everyone is safely underground. Here's where it gets good.
"The shift supervisor insisted that the radiation control supervisor permit him to enter the work area. The radiation control supervisor resisted, but finally accompanied the shift supervisor back into the building. As they approached the basement room where the accident had occurred, the radiation levels continued to rise. The radiation control supervisor prohibited the shift supervisor from proceeding. In spite of the prohibition, the shift supervisor deceived the radiation control supervisor and entered the room."
So, with things more or less under control, the shift supervisor tricks the radiation control supervisor and goes into the room full of plutonium.
His "subsequent actions were not observed by anyone. However, there was evidence that he attempted to pour [the plutonium] into a floor drain. His actions caused a third excursion, larger than the first two, activating the alarm system in both buildings."
The shift supervisor proceeded to set off an even bigger nuclear chain reaction!
"The shift supervisor, covered in plutonium organic solution, immediately returned to the underground tunnel. He died about one month after the accident," having received four times the fatal dose of radiation. Everyone else survived.
Even if the shift supervisor had lived, he would still qualify for a Darwin Award. That much radiation causes sterility.
"A flash of insight."
"Now hiring: Nuclear Plant Shift Supervisor."
